Brands Being Used in Pornography Search Engine Poisoning

Recently, during one of our TigerTrax™Targeted Threat Intelligence engagements, we were performing passive threat assessments for a popular consumer brand. In the engagement, we not only gathered targeted threat intelligence about their IT environments, applications and hosting partners, but also around the use of their brand on a global scale. The client had selected to take advantage of our dark net intelligence capabilities as well, and were keenly interested in how the dark net, deep web and underground portions of the Internet were engaged with their brand. This is a pretty common type of engagement for us, and we often find a wide variety of security, operational and reputational issues.

This particular time around, we ran into a rather interesting and new concern, at least on the dark net. In this case, a dark net pornography site was using the consumer brand embedded as an HTML comment in the porn site’s main pages. Overall, there were several hundred name brands in the comments. This seems to have been performed so that the search engines that index the site on the dark net, associate the site with the brands. That means when a user searches for the brand name, they get the porn site returned as being associated. In this case, it was actually the first link on several of the dark net search sites we tested. The porn site appears to be using the brand names to lure eyeballs to the site – essentially to up the chance of finding a subscriber base for their particularly nasty set of pornography offerings. Search engine poisoning has been an issue on the public web for some time, and it is a commonly understood tactic to try and link your content to brands, basically serving as “click bait” for users. However, on the dark net, this was the first time we had observed this tactic being used so overtly.

The brand owner was, of course, concerned about this illicit use of their brand. However, there is little they could do to respond, other than reporting the site to the authorities. Instead, after discussing various options, we worked with them to identify an action and response plan for how they would handle the problem if it became a public concern. We also worked with them to identify a standard process that they could follow to bring their existing legal, marketing, management and other parts of their incident response team up to date on threats like these as they emerged.

The client was very pleased to have the discussion and with the findings we identified. While any misuse of their brand is a concern, having their brand associated with pornography or other illicit material is certainly unnerving. In the end, there is little that organizations can do, other than work with authorities or work on take down efforts if the brand is misused on the public web. However, having the knowledge that the issue is out there, and working to develop the threat into existing response plans certainly goes a long way to help them minimize these kinds of risks.

3 Reasons I Believe In #CMHSecLunch And Its Mission

I get asked quite often about why I started CMHSecLunch and what the goals behind it are. I wanted to take a moment and discuss it on the blog.

First, if you aren’t a security person in Columbus, Ohio, you might not have heard of the event. Here are the details about it.

Every month, on the second Thursday, my team loosely organizes a simple lunch meet up at one of the local mall foodcourts. It is free, open to all – including non-security folks, kids and interested parties. There is usually a topic like “physical security”, “supply chain”, “threat intelligence”, “pen-testing”, etc. We also usually have something for people to fiddle with while they talk, like locks and lock picks, Legos, smart bits, cards and readers, etc. We find that having something to play with physically seems to help the attendees converse more easily.

The mission of CMHSecLunch was to emulate the “hallway conversations” part of security conferences, and to open up the security community to even larger groups of folks that may be interested, but may not have an easy way to get involved. I wanted it to be less formal than something like an ISSA/ISACA event, be free, loose in organization and really help people make personal connections with each other and the community at large.

The mission started in roughly 2012, and while we took a couple of breaks, is over 4 years old. Sure, there a lot of other events and even a couple of knock off lunches – emulation is a compliment 🙂 – but those usually include some formal presentation, vendor sponsor pitches or some other form of noise as the center of the event. I wanted to avoid all of that and put people at the center of the event. No vendor pitches, no one buys your lunch – so you don’t owe anyone anything either implicit or implied – and since it is in an open public space like a mall food court – there is no separation of infosec from the general public. Everyone can see, talk and ask questions without all of the speed bumps and smoke/mirrors and sense of separation sometimes associated with the infosec community. We’ve had middle school kids, college students, IT folks, janitors at the mall, infosec practitioners, managers and executives join us, engage and ask questions.

So, the #1 reason that I support CMHSecLunch is just that – the open nature and open discussion that comes from it. Thus far, nearly everyone who sits down with us at these events leaves their ego at home or in their car. We’ve had honest discussions from technical to personal, jokes and explanations, stories and anecdotes and even some project launches. Overall, the sense of openness and community has been one of the most amazing parts of my career. Sometimes there are 3 people, sometimes 30 – but I always leave with a smile and a renewed sense of community.

The second reason I believe in CMHSecLunch is that I have seen it bring new talent and fresh energy to the community. People have personally told me that because it was an open, public space and there was nothing expected, that they had the courage to finally approach infosec folks. Many times, people are nervous that they may not fit in, or have the skill set or knowledge of security practitioners at the more focused meetings. They may not have the management or budget support to go to conferences, ISSA/ISACA/OWASP events or even know that they exist. But a lot of people are on Twitter. A lot of people aren’t nervous to go to a mall food court. A lot of people can afford to invest in a fast food or brown bag lunch to get to know people to get started. That’s the crucial ingredient – to make it easy for new folks to join and engage. We need them. The community desperately needs new talent, fresh ideas and new resources that aren’t already locked into the echo chamber of infosec. In fact, I would say new ideas and new talent will make or break infosec over the next 10 years. I believe CMHSecLunch is an easier way for those new people to get started.

Lastly, I love bringing security discussions out of closed business conference rooms and into the mall. I absolutely get thrilled when people around us ask about lock picking or smart bits or whatever we are playing with. I love it when people lean in to listen about hacking or about how credential theft works. We have seen so many surrounding tables clearly listening in – that I have made it a habit to simply ask them to join us and explain the mission. It’s a beautiful thing. Remove the smoke, mirrors and mysticism of infosec – and everyday people are suddenly interested again. They become a little less apathetic, a little less distant and a lot more aware. Isn’t that what we have always asked for as a community? Didn’t we always want everyday users to be more engaged, more aware and more security capable? I truly believe that it will take bringing the public into the fold to make that happen. I believe that events like CMHSecLunch – loosely organized, free, open to the public, held in common public locations and developed on a spirit of inclusion, just might be a way forward. Mostly, I believe in the open, honest and caring attitudes of people, regardless of what community they believe themselves to be a part of. Thus, I believe in CMHSecLunch and our mission…

Wanna give it a try? If you are around central Ohio, you can find the schedule, locations and times here. Want to start your own event, in your area? Ping me on Twitter (@lbhuston) and I’ll be happy to discuss what I did to promote it, and how I would go about it. If I can help you get a group started, I will. That’s it. That’s why I believe. I hope you will believe too… 

Passive Assessments Continue to Astound

Our passive assessment capability continues to astound us with the things we find. I haven’t seen this many obvious hits since the early days of vulnerability scanning…

It seems that many organizations are missing issues that lie outside of their perimeter. Hosted sites, cloud-based systems and rogue network segments abound. Brand-focused assessments and passive testing of the security posture of partners, providers and external resources have proven to our clients to be a tipping point moment. It has become clear to them and us that a significant portion of the threats and attack surface have moved into wider distribution outside the network perimeter of yesterday. 

Client have been using this capability to test and audit their own risks, but also their vendors, partners and cloud “en masse”.

We are looking for 3-5 key organizations to put together a summit and think tank group to develop standards and best practices together for how to best use passive assessments and targeted threat intelligence on an enterprise level. If your organization would like to discuss passive assessment and potentially engaging in the best practices development summit, please reach out to us on Twitter (@microsolved) or contact your account executive/project manager to arrange for a quick call. Thanks and we look forward to bringing these game changing new tools to organizations around the world shortly!

3 Tools Security Teams Need to Look at Today

I would urge most security teams to hit pause for an hour and take a moment to look at these three tools that may add leverage to the work you are doing.

1. Python LogTools – This is an excellent python library that makes parsing web logs, primarily Apache logs, easy and useful. The capability also can be trivially expanded to analyze other types of logs and system outputs with a little bit of text hacking. Seriously, we know you aren’t reading the logs – find a way to use programatic tools – even if that just means you are parsing for specific issues. I know, I know – you have the SEIM – but honestly, parse the logs. You’ll likely be amazed what you find…

2. Open Source Web Task Manager – Taskfreak – Nearly every team we talk to asks about coordinating task and resource management on other security teams. Here is a free tool set that you can you can use, apart from the more difficult enterprise tools and bloatware. Get a team server or instance and share tasks and resources. Done! 

3. Nmap – yeah, we said it – NMAP! – Oh, I know – you’ve used it. It comes on Kali and nearly every distro – but forget using it for pen-testing and auditing. Now, with a clear mind – begin to think about how you can use nmap to know what’s out there. Inventory of systems and services, done. Ongoing runs to detect new devices, done. Ongoing runs to find new services on known network segments, done. Periodic runs to test network speeds and connectivity for routing issues, done. Gateway checks, done. Detection of new devices by parsing DHCP logs and launching runs – a poor man’s NAC tool, done. There are so many things you can do with nmap other than pen-testing that I am thinking of just becoming an nmap consultant. C’mon – learn the basics and then use the basic tool in new ways to solve problems you already have. Nmap and some simple scripting can up your security team’s game. Give it a shot…

The Dark Net Seems to be Changing

The dark net is astounding in its rapid growth and adoption. In my ongoing research work around underground sites, I continue to be amazed at just how much traditional web-based info is making its way to the dark net. As an example, in the last few research sessions, I have noticed several sites archiving educational white papers, economic analyses and more traditional business data – across a variety of languages. I am also starting to see changes in the tide of criminal-related data and “black market” data, in that the density of that data has begun to get displaced, in my opinion, by more traditional forms of data, discourse and commercialization.

It is not quite to the level of even the early world wide web, but it is clearly headed in a direction where the criminal element, underground markets and other forms of illicit data are being forced to share the dark net with significantly more commercial and social-centric data. Or at least, it feels that way to me. I certainly don’t have hard metrics to back it up, but it feels that way as I am working and moving through the dark net in my research. 

There is still a ways to go, before .onion sites are paved and turned into consumer malls – but that horizon seems closer now than ever before. Let me know what you think on Twitter (@lbhuston).

Great Article on Spotting Skimmers

I ran across this great article with tips on spotting credit card skimmers. Check it out for some pretty good info.

Ever wondered about the prices that criminals pay for skimmers? We recently studied this and found that the average price for magnetic stripe skimmers was between $100 – $300 US. Kits that include cameras and other techniques for also capturing PIN data (ATM & Chip/PIN transactions) were around 10x that amount on the black market. Home grown solutions are significantly cheaper to build, but often lack the subtlety and camouflage of the more “commercial” offerings.

By the way, note that even where Chip and PIN transactions have become the norm (outside the US), capturing the magnetic track data is still useful for attackers to focus on e-commerce and other card holder not present transactions.

Just a few things to think about… While the credit card theft underground is robust, interesting and dynamic, companies and issuers are working hard to stay on top of things. Unfortunately, the economics involved is complex, and attackers are continually refining all phases of their operations.  

Emulating SIP with HoneyPoint

Last week, Hos and I worked on identifying how to emulate a SIP endpoint with HoneyPoint Security Server. We identified an easy way to do it using the BasicTCP capability. This emulation component emulates a basic TCP service and performs in the following manner:

  • Listens for connections
  • Upon connection, logs the connection details
  • Sends the banner file and awaits a response
  • Upon response, logs the response data
  • Sends the response, repeating the wait and log loop, resending the response to every request
  • When the connection limit is reached, it closes the connection
It has two associated files for the emulation:
  • The banner file – “banner”
  • The response file – “response”

In our testing, we were able to closely emulate a SIP connection by creating a banner file that was blank or contained only a CR/LF. Then we added the appropriate SIP messaging into the response file. This emulates a service where thew connection is completed and logged, and the system appears to wait on input. Once input is received, then a SIP message is delivered to the client. In our testing, the SIP tools we worked with accepted the emulation as SIP server and did not flag any anomalies.

I’ll leave the actual SIP messaging as a research project for the reader, to preserve some anonymity for HPSS users. But, if you are an HPSS user and would like to do this, contact support and we will provide you with the specific messaging that we used in our testing.

As always, thanks for reading and especially thanks for being interested in HoneyPoint. We are prepping the next release, and I think you will be blown away by some of the new features and the updates to the documentation. We have been hard at work on this for a while, and I can’t wait to share it with you shortly!

MSI’s Targeted Threat Intelligence is Adding Huge Value to M&A Due Diligence

Many of our clients have been using our Targeted Threat Intelligence service offerings to assist them with due diligence efforts around mergers and acquisitions activities. For many years, clients have leveraged MSI services during and after an acquisition, usually to perform security assessments, identify control gaps and validate remediations. Our network discovery and mapping tools, including MachineTruth, have been an excellent fit for helping them understand exactly what their new architectures look like and where it makes sense for interconnections and network hardening.

Now, with TigerTrax™ and MSI’s passive assessment platform, our threat intelligence and passive assessment capabilities are aiding clients in the due diligence process, making us an excellent partner throughout the M&A lifecycle! These new offerings allow us to add brand/trend data and cyber-security analysis to potential M&A targets, before they are even aware that they are prospects and without their knowledge or contractual engagement. It allows organizations more flexibility in identifying potential Intellectual Property leaks, poor security practices or other IT risks before approaching an acquisition target. The brand/trend reputational data is blended in, providing a new lens to look for potential issues around customer service, activism, impacts from poor online or data hygiene, etc.

While these same techniques have proven to be a boon for vendor supply chain security, they have been leveraged in M&A activity for a year longer. MSI has a strong history in this space and continues to innovate with new data sources, optimized processes and bleeding edge tools for making M&A safer, more efficient and more profitable. To learn more about our M&A offerings, hear about our work and research in the M&A space or discuss how we can assist your organization with M&A services, please drop us a line at info@microsolved.com, or give us a call at (614) 351-1237 today.

Hosting Providers Matter as Business Partners

Hosting providers seem to be an often overlooked exposure area for many small and mid-size organizations. In the last several weeks, as we have been growing the use of our passive assessment platform for supply chain assessments, we have identified several instances where the web site hosting company (or design/development company) is among the weakest links. Likely, this is due to the idea that these services are commodities and they are among the first areas where organizations look to lower costs.

The fall out of that issue, though, can be problematic. In some cases, organizations are finding themselves doing business with hosting providers who reduce their operational costs by failing to invest in information security.* Here are just a few of the most significant issues that we have seen in this space:
  • “PCI accredited” checkout pages hosted on the same server as other sites that are clearly under the control of an attacker
  • Exposed applications and services with default credentials on the same systems used to host web sites belonging to critical infrastructure organizations
  • Dangerous service exposures on hosted systems
  • Malware infested hosting provider ad pages, linked to hundreds or thousands of their client sites hosted with them
  • Poorly managed encryption that impacts hundreds or thousands of their hosted customer sites
  • An interesting correlation of blacklisted host density to geographic location and the targeted verticals that some hosting providers sell to
  • Pornography being distributed from the same physical and logical servers as traditional businesses and critical infrastructure organizations
  • A clear lack of DoS protection or monitoring
  • A clear lack of detection, investigation, incident response and recovery maturity on the part of many of the vendors 
It is very important that organizations realize that today, much of your risk extends well beyond the network and architectures under your direct control. Partners, and especially hosting companies and cloud providers, are part of your data footprint. They can represent significant portions of your risk, and yet, are areas where you may have very limited control. 
 
If you would like to learn more about using our passive assessment platform and our vendor supply chain security services to help you identify, manage and reduce your risk – please give us a call (614-351-1237) or drop us a line (info /at/ MicroSolved /dot/ com). We’d love to walk you through some of the findings we have identified and share some of the insights we have gleaned from our analysis.
 
Until next time, thanks for reading and stay safe out there!
 
*Caveat: This should not be taken that information security is correlated with cost. We have seen plenty of “high end”, high cost hosting companies with very poor security practices. The inverse is also true. Validation is the key…
