In my last blog post, I discussed one method of dumping LSASS where we created a DLL that we injected into Task Manager. We could then create an LSASS dump from Task Manager, and the DLL would hook the API calls responsible for creating the file and change the filename to something else. This allowed […]
Going to DEF CON was a dream I never thought would come to fruition. I remember 2009 being in 8th grade. Reading a physical copy of the magazine Wired. Sitting in the back of parent's minivan on the way to visit family in Milwaukee, WI, and seeing pictures and reading about the largest hacking conference […]
Finding a great pentesting partner can be a challenge and there is much greater risk in changing firms than sticking with a partner you can trust. A good firm should have sufficient staff and work history to ensure that you can still get a new set of eyes without losing consistency or efficiency.
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.

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 […]
