Decentralized Finance empowers individuals by eliminating traditional gatekeepers, yet it introduces a unique set of challenges, especially in terms of risk. From smart contract vulnerabilities to asset volatility and evolving regulatory frameworks, navigating the DeFi landscape requires a keen eye for potential pitfalls. Understanding the underlying technologies and identifying the associated risks critically impacts both seasoned investors and new participants alike.

This article will serve as your essential guide to effectively navigating DeFi, delving into the intricacies of risk assessment within this dynamic domain. We will explore the fundamental aspects of DeFi, dissect the potential security threats, and discuss advanced technologies for managing risks. Whether you’re an enthusiast or investor eager to venture into the world of Decentralized Finance, mastering these essentials is imperative for a successful and secure experience.

Understanding Decentralized Finance (DeFi)

Decentralized Finance, or DeFi, is changing how we think about financial services. By using public blockchains, DeFi provides financial tools without needing banks or brokers. This makes it easier for people to participate in financial markets. Instead of relying on central authorities, DeFi uses smart contracts. These are automated programs on the blockchain that execute tasks when specific conditions are met. They provide transparency and efficiency. Nonetheless, DeFi has its risks. Without regulation, users must be careful about potential fraud or scams. Each DeFi project brings its own set of challenges, requiring specific risk assessments different from traditional finance. Understanding these elements is key to navigating this innovative space safely and effectively.

Definition and Key Concepts

DeFi offers a new way to access financial services. By using public blockchains, it eliminates the need for lengthy processes and middlemen. With just an internet connection, anyone can engage in DeFi activities. One crucial feature of DeFi is the control it gives users over their assets. Instead of storing assets with a bank, users keep them under their own control through private keys. This full custody model ensures autonomy but also places the responsibility for security on the user. The interconnected nature of DeFi allows various platforms and services to work together, enhancing the network’s potential. Despite its promise, DeFi comes with risks from smart contracts. Flaws in these contracts can lead to potential losses, so users need to understand them well.

The Growth and Popularity of DeFi

DeFi has seen remarkable growth in a short time. In just two years, the value locked in DeFi increased from less than $1 billion to over $100 billion. This rapid expansion shows how appealing DeFi is to many people. It mimics traditional financial functions like lending and borrowing but does so without central control. This appeals to both individual and institutional investors. With the DeFi market projected to reach $800 billion, more people and organizations are taking notice. Many participants in centralized finance are exploring DeFi for trading and exchanging crypto-assets. The unique value DeFi offers continues to attract a growing number of users and investors, signifying its importance in the financial landscape.

Identifying Risks in DeFi

Decentralized finance, or DeFi, offers an exciting alternative to traditional finance. However, it also presents unique potential risks that need careful evaluation. Risk assessments in DeFi help users understand and manage the diverse threats that come with handling Digital Assets. Smart contracts, decentralized exchanges, and crypto assets all contribute to the landscape of DeFi, but with them come risks like smart contract failures and liquidity issues. As the recent U.S. Department of the Treasury’s 2023 report highlights, DeFi involves aspects that require keen oversight from regulators to address concerns like illicit finance risks. Understanding these risks is crucial for anyone involved in this evolving financial field.

Smart Contract Vulnerabilities

Smart contracts are the backbone of many DeFi operations, yet they carry significant risks. Bugs in the code can lead to the loss of funds for users. Even a minor error can cause serious vulnerabilities. When exploited, these weaknesses allow malicious actors to steal or destroy the value managed in these contracts. High-profile smart contract hacks have underscored the urgency for solid risk management. DeFi users are safer with protocols that undergo thorough audits. These audits help ensure that the code is free from vulnerabilities before being deployed. As such, smart contract security is a key focus for any DeFi participant.

Asset Tokenomics and Price Volatility

Tokenomics defines how tokens are distributed, circulated, and valued within DeFi protocols. These aspects influence user behavior, and, in turn, token valuation. DeFi can suffer from severe price volatility due to distortions in supply and locked-up tokens. Flash loan attacks exploit high leverage to manipulate token prices, adding to instability. When a significant portion of tokens is staked, the circulating supply changes, which can inflate or deflate token value. The design and incentives behind tokenomics need careful planning to prevent economic instability. This highlights the importance of understanding and addressing tokenomics in DeFi.

Pool Design and Management Risks

Managing risks related to pool design and strategies is crucial in DeFi. Pools with complex yield strategies and reliance on off-chain computations introduce additional risks. As strategies grow more complex, so does the likelihood of errors or exploits. Without effective slashing mechanisms, pools leave users vulnerable to losses. DeFi risk assessments stress the importance of robust frameworks in mitigating these threats. Additionally, pools often depend on bridges to operate across blockchains. These bridges are susceptible to hacks due to the significant value they handle. Therefore, rigorous risk management is necessary to safeguard assets within pool operations.

Developing a Risk Assessment Framework

In the realm of decentralized finance, risk assessment frameworks must adapt to unique challenges. Traditional systems like Enterprise Risk Management (ERM) and ISO 31000 fall short in addressing the decentralized and technology-driven features of DeFi. A DeFi risk framework should prioritize identifying, analyzing, and monitoring specific risks, particularly those associated with smart contracts and governance issues. The U.S. Department of Treasury has highlighted these challenges in their Illicit Finance Risk Assessment, offering foundational insights for shaping future regulations. Building a robust framework aims to foster trust, ensure accountability, and encourage cooperation among stakeholders. This approach is vital for establishing DeFi as a secure alternative to traditional finance.

General Risk Assessment Strategies

Risk assessment in DeFi involves understanding and managing potential risks tied to its specific protocols and activities. Due diligence and using effective tools are necessary for mitigating these risks. This process demands strong corporate governance and sound internal controls to manage smart contract, liquidity, and platform risks. Blockchain technology offers innovative strategies to exceed traditional risk management methods. By pairing risk management with product development, DeFi protocols can make informed decisions, balancing risk and reward. This adaptability is essential to address unique risks within the DeFi landscape, ensuring safety and efficiency in financial operations.

Blockchain and Protocol-Specific Evaluations

Evaluating the blockchain and protocols used in DeFi is essential for ensuring security and robustness. This includes assessing potential vulnerabilities and making necessary improvements. Formal verification processes help pinpoint weaknesses, enabling protocols to address issues proactively. Blockchain’s inherent properties like traceability and immutability aid in mitigating financial risks.

Educating teams about blockchain and smart contracts is vital, as is understanding the evolving regulatory landscape. Forming partnerships with technology and cybersecurity firms can improve capabilities, offering comprehensive services in DeFi. New risk management tools, such as decentralized insurance and smart contract audits, show a commitment to embracing innovation. Balancing technological advances with regulatory compliance ensures that DeFi systems remain secure and reliable.

Security Threats in DeFi

Decentralized Finance, or DeFi, is changing how we think about finance. It uses blockchain technology to move beyond traditional systems. However, with innovation comes risk. DeFi platforms are susceptible to several security threats. The absence of a centralized authority means there’s no one to intervene when problems arise, such as smart contract bugs or liquidity risks. The U.S. Treasury has even noted the sector’s vulnerability to illicit finance risks, including criminal activities like ransomware and scams. DeFi’s technological complexity also makes it a target for hackers, who can exploit weaknesses in these systems.

Unsecured Flash Loan Price Manipulations

Flash loans are a unique but risky feature of the DeFi ecosystem. They allow users to borrow large amounts of crypto without collateral, provided they repay immediately. However, this opens the door to scams. Malicious actors can exploit these loans to manipulate token prices temporarily. By borrowing and swapping large amounts of tokens in one liquidity pool, they can alter valuations. This directly harms liquidity providers, who face losses as a result. Moreover, these manipulations highlight the need for effective detection and protection mechanisms within DeFi platforms.

Reentrancy Attacks and Exploits

Reentrancy attacks are a well-known risk in smart contracts. In these attacks, hackers exploit a vulnerability by repeatedly calling a withdrawal function. This means they can drain funds faster than the system can verify balances. As a result, the smart contract may not recognize the lost funds until it’s too late. This type of exploit can leave DeFi users vulnerable to significant financial losses. Fixing these vulnerabilities is crucial for the long-term security of DeFi protocols. Preventing such attacks will ensure greater trust and stability in the decentralized financial markets.

Potential Phishing and Cyber Attacks

Cyber threats are not new to the financial world, but they are evolving in the DeFi space. Hackers are constantly looking for weaknesses in blockchain technology, especially within user interfaces. They can carry out phishing attacks by tricking users or operators into revealing sensitive information. If successful, attackers gain unauthorized access to crypto assets. This can lead to control of entire protocols. Such risks demand vigilant security practices. Ensuring user protection against cybercrime is an ongoing challenge that DeFi platforms must address. By improving security measures, DeFi can better safeguard against potential cyber threats.

Regulatory Concerns and Compliance

Decentralized finance (DeFi) has grown rapidly, but it faces major regulatory concerns. The US Treasury has issued a risk assessment that highlights the sector’s exposure to illicit activities. With platforms allowing financial services without traditional banks, there is a growing need for regulatory oversight. DeFi’s fast-paced innovations often outstrip existing compliance measures, creating gaps that malicious actors exploit. Therefore, introducing standardized protocols is becoming crucial. The Treasury’s assessment serves as a first step to understanding these potential risks and initiating dialogue on regulation. It aims to align DeFi with anti-money laundering norms and sanctions, addressing vulnerabilities tied to global illicit activities.

Understanding Current DeFi Regulations

DeFi platforms face increasing pressure to comply with evolving regulations. They use compliance tools like wallet attribution and transaction monitoring to meet anti-money laundering (AML) and Know Your Customer (KYC) standards. These tools aim to combat illicit finance risks, but they make operations more complex and costly. Regulatory scrutiny requires platforms to balance user access with legal compliance. As regulations stiffen, platforms may alienate smaller users who find these measures difficult or unnecessary. To stay competitive and compliant, DeFi platforms must adapt continuously, often updating internal processes. Real-time transaction visibility on public blockchains helps regulatory bodies enforce compliance, offering a tool against financial crimes.

Impact of Regulations on DeFi Projects

Regulations impact DeFi projects in various ways, enhancing both potential risks and opportunities. The absence of legal certainty in DeFi can worsen market risks, as expected regulatory changes may affect project participation. The US Treasury’s risk assessment pointed out DeFi’s ties to money laundering and compliance issues. As a result, anti-money laundering practices and sanctions are gaining importance in DeFi. Increased scrutiny has emerged due to DeFi’s links to criminal activities, including those related to North Korean cybercriminals. This scrutiny helps contextualize and define DeFi’s regulatory risks, starting important discussions before official rules are set. Understanding these dynamics is vital for project sustainability.

Balancing Innovation and Regulatory Compliance

Balancing the need for innovation with regulatory demands is a challenge for DeFi platforms. Platforms like Chainalysis and Elliptic offer advanced features for risk management, but they often come at high costs. These costs can limit accessibility, particularly for smaller users. In contrast, free platforms like Etherscan provide basic tools that might not meet all compliance needs. As DeFi evolves, innovative solutions are needed to integrate compliance affordably and effectively. A gap exists in aligning platform functionalities with user needs, inviting DeFi players to innovate continuously. The lack of standardized protocols demands tailored models for decentralized ecosystems, highlighting a key area for ongoing development in combining innovation with regulatory adherence.

Utilizing Advanced Technologies for Risk Management

The decentralized finance (DeFi) ecosystem is transforming how we see finance. Advanced technologies ensure DeFi’s integrity by monitoring activities and ensuring compliance. Blockchain forensics and intelligence tools are now crucial in tracing and tracking funds within the DeFi landscape, proving vital in addressing theft and illicit finance risks. Public blockchains offer transparency, assisting in criminal activity investigations despite the challenge of pseudonymity. Potential solutions, like digital identity systems and zero-knowledge proofs, work toward compliance while maintaining user privacy. Collaboration between government and industry is key to grasping evolving regulatory landscapes and implementing these advanced tools effectively.

The Role of AI and Machine Learning

AI and machine learning (AI/ML) are making strides in the DeFi world, particularly in risk assessments. These technologies can spot high-risk transactions by examining vast data sets. They use both supervised and unsupervised learning to flag anomalies in real time. This evolution marks a shift toward more sophisticated DeFi risk management systems. AI-powered systems detect unusual transaction patterns that could point to fraud or market manipulation, enhancing the safety of financial transactions. By integrating these technologies, DeFi platforms continue to bolster their security measures against potential risks and malicious actors.

Real-Time Monitoring and Predictive Analytics

Real-time monitoring is crucial in DeFi for timely risk detection. It allows platforms to spot attacks or unusual behaviors promptly, enabling immediate intervention. Automated tools, with machine learning, can identify user behaviors that may signal prepared attacks. Platforms like Chainalysis and Nansen set the benchmark with their predictive analytics, offering real-time alerts that significantly aid in risk management. Users, especially institutional investors, highly value these features for their impact on trust and satisfaction. Real-time capabilities not only ensure better threat detection but also elevate the overall credibility of DeFi platforms in the financial markets.

Enhancing Security Using Technological Tools

DeFi’s growth demands robust security measures to counter potential risks. Tools like blockchain intelligence, such as TRM, evolve to support compliance while maintaining privacy. The use of digital identities and zero-knowledge proofs is crucial in improving user privacy. The U.S. Treasury emphasizes a private-public collaboration to enhance cyber resilience in DeFi. Blockchain’s immutable nature offers a strong foundation for tracking and preventing illicit finance activities. Technological tools like blockchain forensics are vital for ensuring the compliance and integrity of the DeFi ecosystem, providing a level of security that surpasses traditional finance systems.

Strategies for Robust DeFi Risk Management

Decentralized finance, or DeFi, shows great promise, but it comes with risks. Effective DeFi risk management uses due diligence, risk assessment tools, insurance coverage, and careful portfolio risk management. These strategies help handle unique risks such as smart contract and liquidity risks. As DeFi grows, it also faces scrutiny for involvement in illicit finance. This calls for strong risk management strategies to keep the system safe. Smart contract risks are unique to DeFi. They involve threats from potential bugs or exploits within the code. Managing these risks is crucial. Additionally, DeFi must address systemic risk, the threat of an entire market collapse. Lastly, DeFi platforms face platform risk, related to user interfaces and security. These require comprehensive approaches to maintain platform integrity and user trust.

Due Diligence and Thorough Research

Conducting due diligence is essential for effective DeFi risk management. It helps users understand a DeFi protocol before engaging with it. By performing due diligence, users can review smart contracts and governance structures. This contributes to informed decision-making. Assessing the team behind a DeFi protocol, as well as community support, is crucial. Due diligence also gives insights into potential risks and returns. This practice can aid in evaluating the safety and viability of investments. Furthermore, due diligence often includes evaluating the identity and background of smart contract operators. This can be facilitated through Know Your Customer (KYC) services. In doing so, users can better evaluate the potential risks associated with the protocol.

Integrating Insurance Safeguards

DeFi insurance provides a vital layer of protection by using new forms of coverage. Decentralized insurance protocols, like Nexus Mutual and Etherisc, protect against risks like smart contract failures. These systems use pooled user funds for quicker reimbursements, reducing reliance on traditional insurers. This method makes DeFi safer and more transparent. Users can enhance their risk management by purchasing coverage through decentralized insurance protocols. These systems use blockchain technology to maintain transparency. This reassurance boosts user confidence, much like traditional financial systems. Thus, decentralized insurance boosts DeFi’s appeal and safety.

Strategic Partnership and Collaboration

Strategic partnerships strengthen DeFi by pairing with traditional finance entities. DeFi protocols have teamed up with insurance firms to cover risks like smart contract hacks. These collaborations bring traditional risk management expertise into DeFi’s transparent and autonomous world. Partnerships with financial derivatives providers offer hedging solutions. However, they may incur high transaction fees and counterparty risks. Engaging with industry groups and legal experts also helps. It enhances trust and effective compliance risk management within DeFi protocols. Additionally, traditional financial institutions and DeFi are seeking alliances. These collaborations help integrate and manage substantial assets within decentralized finance ecosystems, enriching the DeFi landscape.

Opportunities and Challenges in DeFi

Decentralized finance, or DeFi, is reshaping how financial services operate. By using smart contracts, these platforms enable transactions like lending, borrowing, and trading without needing banks. With these services come unique risks, such as smart contract failures and illicit finance risks. DeFi platforms offer new opportunities but also demand careful risk assessments. Companies might need advisory services from accounting firms as they adopt these technologies. AI and machine learning hold promise for boosting risk management, despite challenges such as cost and data limitations. The US Department of the Treasury’s involvement shows the importance of understanding these risks before setting regulations.

Expanding Global Market Access

DeFi opens doors to global markets by letting companies and investors engage without middlemen. This reduces costs and boosts efficiency. With access to global financial markets, businesses and investors can enjoy economic growth. From lending to trading, DeFi offers users a chance to join in global financial activities without traditional banks.

Ensuring Cybersecurity: Blocking Discord Access with Firewall Rules

Posted on June 18, 2024 by Brent Huston

I. Introduction

Purpose of Blocking Discord Access

Social media and communication platforms like Discord are everywhere in today’s digital landscape. However, their widespread use also introduces significant cybersecurity risks. Discord, known for its extensive user base and real-time communication features, can be a vector for malicious actors’ malware distribution and command and control (C2) operations. Blocking access to Discord within a corporate environment is a proactive measure to mitigate these risks.

Importance of Controlled Access to Prevent Malware Command and Control

Controlling access to external platforms is crucial in preventing unauthorized use of corporate resources for malicious purposes. By restricting access to platforms like Discord, organizations can reduce the risk of malware infections, data breaches, and unauthorized communications. This measure helps keep network integrity and security intact, safeguarding sensitive business information from cyber threats.

II. Assessing Business Needs

Identifying Users with Legitimate Business Needs

Before implementing a blanket ban on Discord, it’s essential to identify any legitimate business needs for accessing the platform. This could include marketing teams monitoring brand presence, developers collaborating with external partners, or customer support teams engaging with clients through Discord channels.

Documenting and Justifying Business Needs

Once legitimate needs are identified, they should be documented comprehensively. This documentation should include the specific reasons for access, the potential benefits to the business, and any risks associated with allowing such access. This step ensures that decisions are transparent and justifiable.

Approval Process for Access

Establish a formal approval process for users requesting access to Discord. This process should involve a thorough IT and security team review, considering the documented business needs and potential security risks. Approved users should be granted access through secure, monitored channels to ensure compliance with corporate policies.

III. Technical Controls

A. Network Segmentation

Isolating Critical Systems

One of the fundamental strategies in cybersecurity is network segmentation. Organizations can limit the potential impact of a security breach by isolating critical systems from the rest of the network. Critical systems should be placed in separate VLANs (Virtual Local Area Networks) with strict access controls.

Implementing VLANs

Creating VLANs for different departments or user groups can help manage and monitor network traffic more effectively. For instance, placing high-risk users (those needing access to external platforms like Discord) in a separate VLAN allows for focused monitoring and control without impacting the broader network.

B. Firewall Rules

Blocking Discord-Related IPs and Domains

To block Discord access, configure firewall rules to block known Discord IP addresses and domain names. For example:

! Block Discord IP addresses
access-list 101 deny ip any host 162.159.129.233
access-list 101 deny ip any host 162.159.128.233

! Block Discord domain names
ip domain list discord.com
ip domain list discord.gg
access-list 101 deny ip any host discord.com
access-list 101 deny ip any host discord.gg

! Apply the access list to the appropriate interface
interface GigabitEthernet0/1
 ip access-group 101 in

For comprehensive lists of Discord servers and IPs to block, refer to resources such as:

Creating Whitelists for Approved Users

For users with approved access, create specific firewall rules to allow traffic. This can be done by setting up a whitelist:

! Allow approved users to access Discord
access-list 102 permit ip host approved_user_ip any

! Apply the whitelist access list to the appropriate interface
interface GigabitEthernet0/1
 ip access-group 102 in

C. Proxy Servers

Filtering Traffic

Utilize proxy servers to filter and control web traffic. Proxy servers can block access to Discord by filtering requests to known Discord domains. This ensures that only approved traffic passes through the network.

Monitoring and Logging Access

Proxy servers should also be configured to monitor and log all access attempts. These logs should be reviewed regularly to detect unauthorized access attempts and potential security threats.

D. Application Control

Blocking Discord Application

Application control can prevent the installation and execution of the Discord application on corporate devices. Use endpoint security solutions to enforce policies that block unauthorized software.

Allowing Access Only to Approved Instances

For users who need Discord for legitimate reasons, ensure they use only approved instances. This can be managed by allowing access only through specific devices or within certain network segments, with continuous monitoring for compliance.

Conclusion

Blocking Discord access in a corporate environment involves a multi-layered approach combining policy enforcement, network segmentation, firewall rules, proxy filtering, and application control. Organizations can mitigate the risks associated with Discord by thoroughly assessing business needs, documenting justifications, and implementing robust technical controls while allowing necessary business functions to continue securely.

All About Credit Union Credential Stuffing Attacks

Posted on October 5, 2020 by Brent Huston

Credential stuffing attacks continue to be a grave concern for all organizations worldwide. However, for many Credit Unions and other financial institutions, they represent one of the most significant threats. They are a common cause of data breaches and are involved in some 76% of all security incidents. On average, our honey nets pretending to be Credit Union and other financial services experience targeted credential stuffing attacks several times per week.

What Is Credential Stuffing?

“Credential stuffing occurs when hackers use stolen information, such as usernames and passwords from database breaches or phishing software from one account, and attempt to gain access to another. The hackers prey on people’s habit of using the same usernames and passwords for multiple sites. Using automated tools, they run large amounts of stolen information across multiple sites looking to find the same usernames and passwords being used elsewhere. Once they find a match, they can monetize the personal and financial information they gather.” (ardentcu.org)

How Common is Credential Stuffing?

Beyond our honey nets, which are completely fake environments used to study attackers, credential stuffing and the damage it causes is quite starteling. Here are some quick facts:

It is estimated that automated credential-stuffing attempts makes up 90% of enterprise login traffic in the US. (securityboulevard.com)
It’s estimated that credential stuffing costs companies more than $5 billion a year and creates havoc with consumers. (ardentcu.org)
According to Akamai’s latest State of the Internet report on credential stuffing, its customers alone were deluged by 30 billion malicious login attempts between November 2017 and June this year, an average of 3.75 billion per month. (theregister.com)
Significant credential stuffing attacks are a favorite of professional hacking groups from Russia, India, Asia and Africa. They often gather extensive lists of stolen and leaked credentials through advanced Google hacking techniques, by combing social media for password dumps (so called “credential spills”) and by purchasing lists of exposed credentials from other criminals on the dark web. Lists of member information from compromised online banking, online retailers and business association sites are common. This information often includes names, addresses, bank account numbers/credit card numbers, social security numbers, phone numbers and other sensitive data – enabling credential stuffing and social engineering attacks against victims around the world.

What Can Credit Unions Do About Credential Stuffing?

The key to handling this threat is to be able to prevent, or at the very least, identify illicit login attempts and automate actions in response to failed logins. Cybercriminals use a variety of tools, rented botnets (including specifically built credential stuffing bots) and brute force attacks to pick off less than strong passwords all around the Internet. Then, as we discussed above, they use that stolen information to probe your credit union for the same login credentials.

The first, and easiest step, in reducing these cybercriminals’ success rate is to teach all of your legitimate users not to use the same password across multiple systems, and NEVER use passwords from public sites like Facebook, LinkedIn, Instagram, Pinterest or Twitter for example, as account credentials at work or on other important sites. Instead, suggest that they use a password manager application to make it simple to have different passwords for every site. Not only does this help make their passwords stronger, but it can even reduce support costs by reducing password reset requests. Ongoing security awareness is the key to helping them understand this issue and the significance their password choices have on the security of their own personal information and that of the company.

Next, the Credit Union should have a complete inventory of every remote login service, across their Internet presence. Every web application, email service, VPN or remote access portal and every single place that a cybercriminal could try or use their stolen credentials to gain an account takeover. Once, the Credit Union knows where login credentials can be used, they should go about preventing abuse and cyberattacks against those attack surfaces.

The key to prevention should start with eliminating any Internet login capability that is not required. It should then progress to reducing the scope of each login surface by restricting the source IP addresses that can access that service, if possible. Often Credit Unions are able to restrict this access down to specific countries or geographic areas. While this is not an absolute defense, it does help to reduce the impacts of brute force attacks and botnet scans on the login surfaces.

The single best control for any authentication mechanism, however, is multi factor authentication (MFA) (basically a form of secure access code provided to the user). Wheverever possible, this control should be used. While multi factor authentication can be difficult to implement on some services, it is widely available and a variety of products exist to support nearly every application and platform. Financial services should already be aware of MFA, since it has been widely regulated by FFIEC, NCUA and FDIC guidance for some time.

More and more, however, credential stuffing is being used against web mail, Office 365 and other email systems. This has become so common, that a subset of data breaches called Business Email Compromise now exists and is tracked separately by law enforcement. This form of unauthorized access has been wildly popular across the world and especially against the financial services of the United States. Compromised email addresses and the resulting wire transfer fraud and ACH fraud that stems from this form of credential theft/identity theft are among some of the highest financial impacts today. Additionally, they commonly lead to malware spread and ransomware infections, if the attacker can’t find a way to steal money or has already managed to do so.

No matter what login mechanism is being abused, even when MFA is in place, logging of both legitimate access and unauthorized access attempts is needed. In the event that a security breach does occur, this data is nearly invaluable to the forensics and investigation processes. Do keep in mind, that many default configurations of web services and cloud-based environments (like Office 365) have much of this logging disabled by default.

While Credit Unions remain prime targets, having good prevention and detection are a key part of strong risk management against credential stuffing. Practicing incident response skills and business recovery via tabletop exercises and the like also go a long way to stengthening your security team’s capabilities.

How Can MicroSolved Help?

Car Dealership Threat Scenario – Wireless Printer Hacking AP Fraud

Posted on September 16, 2020 by Brent Huston

Today, I wanted to talk about a threat scenario that we have modeled recently. In the scenario, the victim was a car dealership, and the target was to commit accounts payable fraud. The testing scenario is a penetration test against a large group of car dealerships, but our research shows the threat to be valid against any number of organizations.

Here’s the basics of the scenario:

The team found a car dealership with an extensive wireless network. Though the network was encrypted and not available to the public, the team was able to compromise the wireless credentials using a wifi pineapple in a backpack, while pretending to shop for a new car.
The team used the credentials to return later, appearing to wait for a service visit and working from the customer lounge. (The coffee and snacks were great! )
The team logged into the wireless network and quickly identified many devices, workstations and such available. Rather than focus on the workstations or attempt an attack on the users – the team instead focused on the shared printers.
One printer was identified with the name “BackOffice”, and access to the print spool was easily obtained through known default passwords which hadn’t been changed on the device.
Our team made notes of attack their recon attack path, and left the dealership.
Once away from the dealership a couple of simple social engineering calls were made to the accounts payable folks, pretending to be a vendor that we had observed at work at the facility. Without any real information, the accounts payable team member explained when we could expect payment, because accounts payable checks were processed every Thursday morning. The social engineer thanked them and completed the call.
On Thursday morning, the team showed up at the dealership again, pretending to wait for a service appointment. While in the lounge, they accessed the compromised network and printer. This time, taking deeper control of the printer’s file buffer.
The team waited for the accounts payable staff to submit their weekly check printing to the printer. Indeed, around 10:45, the printer file showed up in the printer spool, where our penetration testing team intercepted it.
The team quickly edited the file, changing one of the checks in amount (increasing the amount by several thousand dollars) and the payee (making the check payable to a fictional company of our choosing). They also edited the mailing address to come to our office instead of the original vendor. (PS – we alerted the manager to this issue, so that the bill could be paid later — never harm a client while doing testing!!!)
The file was then re-sent to the printer and released. The whole process occurred in under 3 minutes, so the AP person never even noticed the issue.
One expected control was that perhaps the AP staff would manually reconcile the checks against their expected checks, but this control was not in place and the fake check was mailed to us (we returned it, of course!).

This is a pretty simple attack, against a very commonly exploitable platform. Poor wireless network security and default installs of printer systems are common issues, and often not given much thought in most dealerships. Even when organizations have firewalls and ongoing vulnerability scanning, desktop controls, Anti-Virus, etc. – this type of attack is likely to work. Most organizations ignore their printers – and this is an example of how that can bite you.

These types of threat scenarios are great examples of our services and the threat modeling, fraud testing and penetration testing available.

3 Threats We Are Modeling for Clients These Days

Posted on January 20, 2020 by Brent Huston

Just a quick post today to discuss three threat scenarios we are modeling frequently with clients these days. #ThreatModeling

1) Ransomeware or other malware infection sourced from managed service providers – this scenario is become a very common issue, so common that DHS and several other organizations have released advisories. Attacker campaigns against managed services providers have been identified and many have yielded some high value breaches. The most common threat is spear phishing into a MSP, with the attackers eventually gaining access to the capability to push software to the clients. They then push a command and control malware or a ransomware infection down the pipe. Often, it is quite some time before the source of the event is traced back to the MSP. The defenses here are somewhat limited, but the scenario definitely should be practiced at the tabletop level. Often, these MSPs have successfully passed a SOC audit, but have very little security maturity beyond the baselines.

2) Successful credential stuffing attacks against Office 365 implementations leading to wire/ACH/AP fraud – This is another very common scenario, not just for banks and credit unions, but a lot of small and mid-size organizations have fallen victim to it as well via account payable attacks. In the scenario, either a user is phished into giving up credentials, or a leaked set of credentials is leveraged to gain access to the Office 365 mail and chat system. The attackers then leverage this capability to perform their fraud, appearing to come from internal email accounts and chats. They often make use of stored forms and phish their way to other internal users in the approval chain to get the money to actually move. Once they have their cash, they often use these email accounts to spread malware and ransomware to other victims inside the organization or in business partners – continuing the chain over and over again. The defenses here are to MFA, limited access to the O365 environment to require VPN or other IP-specifc filtering, hardening the O365 environment and enabling many of the detection and prevention controls that are off by default.

3) Voicemail hacking and dial-system fraud – I know, I know, it’s 2020… But, this remains an incredibly impactful attack, especially against key management employees or employees who traffic in highly confidential data. Often this is accessed and then either used for profit via trading (think M&A info) or as ransom/blackmail types of social engineering. Just like above, the attackers often hack one account and then use social engineering to get other users to follow instructions around fraud or change their voicemail password to a given number, etc. Larger corporations where social familiarity of employees and management is low are a common attack target. Dial system fraud for outbound long distance remains pretty common, especially over long weekends and holidays. Basically, the attackers hack an account and use call forwarding to send calls to a foreign number – then sell access to the hacked voicemail line, changing the destination number for each caller. Outbound dial tone is also highly regarded here and quite valuable on the underground markets. Often the fraud goes undetected for 60-90 days until the audit process kicks in, leaving the victim several thousand dollars in debt from the illicit activity. The defenses here are voicemail and phone system auditing, configuration reviews, hardening and lowering lockout thresholds on password attempts.

We can help with all of these issues and defenses, but we love to help organizations with threat scenario generation, threat modeling and attack surface mapping. If you need some insights into outside the box attacks and fraud potential, give us a call. Our engagements in this space are informative, useful and affordable.

Time to protect – BEC Series #3

Posted on November 29, 2018 by Lisa Wallace

A few weeks ago, we published the Business Email Compromise (BEC) Checklist. The question arose – what if you’re new to security, or your security program isn’t very mature?

Since the checklist is based on the NIST model, there’s a lot of information here to help your security program mature, as well as to help you mature as a security practitioner. MSI’s engineers have discussed a few ways to leverage the checklist as a growth mechanism.

Part 1 and Part 2 covered the first checkpoint in the list – Identify.

Pay Attention to Egress Anomalies on Weekends

Posted on September 19, 2016 by Brent Huston

Just a quick note to pay careful attention to egress anomalies when the majority of your employees are not likely to be using the network. Most organizations, even those that are 24/7, experience reduced network egress to the Internet during nights and weekends. This is the perfect time to look for anomalies and to take advantage of the reduced traffic levels to perform deeper analysis such as a traffic level monitoring, average session/connection sizes, anomalies in levels of blocked egress ports, new and never before seen DNS resolutions, etc.

If you can baseline traffic, even using something abstract like net flow, you may find some amazing stuff. Check it out!

From Dark Net Research to Real World Safety Issue

Posted on September 9, 2016 by Brent Huston

On a recent engagement by the MSI Intelligence team, our client had us researching the dark net to discover threats against their global brands. This is a normal and methodology-driven process for the team and the TigerTrax™ platform has been optimized for this work for several years.

We’ve seen plenty of physical threats against clients before. In particular, our threat intelligence and brand monitoring services for professional sports teams have identified several significant threats of violence in the last few years. Unfortunately, this is much more common for high visibility brands and organizations than you might otherwise assume.

In this particular instance, conversations were flagged by TigerTrax from underground forums that were discussing physical attacks against the particular brand. The descriptions were detailed, politically motivated and threatened harm to employees and potentially the public. We immediately reported the issue and provided the captured data to the client. The client reviewed the conversations and correlated them with other physical security occurrences that had been reported by their employees. In today’s world, such threats require vigilant attention and a rapid response.

In this case, the client was able to turn our identified data into insights by using it to gain context from their internal security issue reporting system. From those insights, they were able to quickly launch an awareness campaign for their employees in the areas identified, report the issue to localized law enforcement and invest in additional fire and safety controls for their locations. We may never know if these efforts were truly effective, but if they prevented even a single occurrence of violence or saved a single human life, then that is a strong victory.

Security is often about working against things so that they don’t happen – making it abstract, sometimes frustrating and difficult to explain to some audiences. But, when you can act on binary data as intelligence and use it to prevent violence in the kinetic world, that is the highest of security goals! That is the reason we built TigerTrax and offer the types of intelligence services we do to mature organizations. We believe that insights like these can make a difference and we are proud to help our clients achieve them.
