I’m a fan of full featured and weaponized C2s as much as anyone else to save time if it makes my job easier. Sometimes they can make your job harder when you’re dealing with EDR. A lot of opsec considerations come into play. Just because your C2 supports a particular feature doesn’t necessarily mean you […]
There are many ways to create an LSASS dump file. One of the easiest ways is with Windows Task Manager. Simply right click the LSASS process and click “Create dump file”. This is great, except for the fact that Windows Defender will immediately flag this as malicious. Far from stealthy. Not ideal. This raised some […]

What is Lucee? Lucee is an open-source Cold Fusion Markup Language (CFML) application server and engine intended for rapid development and deployment. It provides a lot of out of the box functionality (tags and functions) to help build web applications. However, if an attacker has access to the Lucee dashboard, these very same functions allow […]
SynerComm's marketing team likes to ask our pentesters for help with their messaging. Like all good hackers, we adapt, automate and improve. So, when we asked our team for some helpful marketing messages, Dylan R. responded within seconds with this. Password security assessments are important because they help ensure that the passwords being used to […]
In February 2017, I co-authored a blog detailing our build of an 8-GPU password cracker. Over the past 8 years, it’s had millions of views and thousands of comments. To all the concerned writers, nothing has melted down and we continue to run 2 nearly identical 8-GPU crackers today. Both are currently running 8 NVIDIA […]

Whether doing security research or troubleshooting networks, network sniffers and packet analysis can be invaluable tools. If you're a network engineer like me, you've probably been holding onto your favorite 4 or 8-port 10/100 hub for 25 years now. The reason is that hubs (not switches) make great network taps. By design, all Ethernet transmissions […]
Whether you are vulnerability scanning to meet compliance requirements or doing it as part of good security practices, there is a universal need. At the time of this article, there are essentially three equally capable and qualified scanning solutions. They include products from Tenable, Rapid7 and Qualys. My point is that each of these scanning solutions, if configured correctly, should produce accurate and similar results.
In penetration testing, it’s important to have an accurate scope and even more important to stick to it. This can be simple when the scope is limited to a company’s internet service provider (ISP) or ARIN provided IP ranges. But in many cases, our client’s public systems have grown to include multiple cloud hosted servers, applications, and services.
