Over the past few years we have seen plenty of news about data being stolen from misconfigured Amazon S3 buckets and other cloud based services. Now attackers are figuring out ways to further abuse these systems beyond simply stealing data.

Magecart, a threat actor group involved in a large amount of attacks, has a currently active campaign targeting S3 hosted sites; the attack infected these sites with malicious javascript that steals customer’s credit card data.

Their attack methodology involves specifically looking for buckets that have write permissions enabled for everyone. When one of these buckets is found, it looks for javascript in the bucket – increasing the likelihood that it’s being used to host a site, or serving assets for a site hosted elsewhere. Javascript files are then edited by the attacker and the Magecart malicious javascript is injected into it.

The javascript runs in the customer’s browser, looks for specific forms, and sends that data to another server when it is submitted. Without detailing this further, as there are many other good breakdowns of exactly what this attack entails that are available. The key take away here will be what can you do to make sure a site you have isn’t hosting this code.

Times are getting hard for concerns that collect or sell information about individuals. People are becoming more concerned about their privacy and want their personal information protected. It’s taken a while, but folks are waking up to the fact that information about who they are, where they live, what they like to do, what they like to buy and a plethora of other information is being systematically collected and sold all the time.

National information security and privacy legislation has been bandied about now for a long time, but with no results as yet. So, the States are getting sick of waiting and are drafting their own privacy acts, especially since the inception of the European Union’s General Data Protection Regulation (GDPR).

Several paths led me to a blog on this topic. I have a friend and a close relative who are currently going through a home loan process. In addition, in a work-related project, I have been researching mortgage fraud and real estate scams. Statistics reveal about 1% of loan applications contained an element of fraud, and it has been on a general upward trend for the last decade.

We are at the end of the second decade of the 21^st century now, and we are still suffering from poor application coding security practices of all sorts. This is costing us big-time in dollars, intellectual property, privacy, security, apprehension and consternation!

As individual consumers, we tend to think of things like identity theft, invasion of privacy and loss of services when we consider the problem of poorly secured applications. But the problem is much broader and deeper than that. Holes in application coding security can also be used to attack communications systems, utility and industrial control systems, supply chains and transportation systems, and military command and control and weapons systems. These kinds of failures can lead to wide-scale confusion, outages, disasters and the deaths of innocents; possibly lots of innocents.

On May 14, 2019 Microsoft announced a vulnerability in RDP – Remote Desktop Services…formerly known as Terminal Services. The vulnerability is significant enough that Microsoft has chosen to publish a patch for Windows XP and Windows 2003 on May 15th – operating systems that have been out of support for a few years now.

Why is this important? The vulnerability is similar to the one that WannaCry leveraged, and allows an attacker to “worm” through the network. Reports say that there is a proof-of-concept exploit; as of this writing on May 19th, the MSI lab hasn’t laid hands on one to test and our research is ongoing.

To quote Microsoft:

“This vulnerability is pre-authentication and requires no user interaction. In other words, the vulnerability is ‘wormable’, meaning that any future malware that exploits this vulnerability could propagate from vulnerable computer to vulnerable computer in a similar way as the WannaCry malware spread across the globe in 2017.”

So what? So…early this morning, a search on shodan.io for “rdp” showed 1058 exposures indexed. A few HOURS later, that number increased to 1062. Externally facing RDP is a very bad idea, and attackers considered it to be low hanging fruit before this vulnerability came to light…now, the stakes are higher.

“My patching is automated” – we’re all good, right? Well…I contacted a friend in a small office yesterday, and suggested that they check. When she inventoried the 4 computers that were set to update automatically…3 of them had not received this update. Due diligence is your friend here, don’t assume.

Patch. Patch now. Share with your friends and colleagues, particularly those who are less than technically savvy. Friends don’t let friends have RDP as an externally facing service!

(Let’s not leave Adobe out of the mix. Adobe’s Patch Tuesday covers 82 CVE’s. EIGHTY TWO? People, we have to do better…)

And remember…is it really paranoia if they ARE out to get you?

Questions? Comments? Are you patched? I’d love to hear from you – lwallace@microsolved.com, or @TheTokenFemale on Twitter!

In several recent engagements, we came across some IoT (Internet of Things) devices within client networks. There’s a growing presence of these ubiquitous devices within corporate environments. They measure, they detect, they capture, they sense. Then they send the info to some app on your phone.

These devices make life easier. Safer. More convenient. Many times, just simply accessible when it was not possible before.

But there can be risks. I’ve always held the belief that security has an inverse relationship with accessibility. The more doors you have to enter a building, the more accessible it is to get inside. But with this accessibility to authorized persons with keys to the doors, likewise, the risk for a burglar to pick the locks to break in increases.

For more than 20 years now, hackers and cyber-criminals have been breaking into computer systems and networks. And for just as long a period of time, manufacturers, networking folk and cyber-security personnel have been developing devices, controls and processes to prevent these people from getting in and raising havoc. The “bad guys” come up with new ways to compromise system security, and then the “good guys” come up with new ways to protect it. Back and forth, forth and back, back and forth… it never seems to stop!
