Kernel Karnage – Part 7 (Out of the Lab and Back to Reality)

Switching hats With Interceptor being successful in blinding $vendor2 sufficiently to run a meterpreter reverse shell, it is time to put on the red team hat and get out of the perfect lab environment.

Introduction - Status Report In the course of these 6 weeks, I’ve covered several aspects of kernel drivers and EDR/AVs kernel mechanisms. I started off strong by examining kernel callbacks and why EDR/AV products … Continue reading Kernel Karnage – Part 6 (Last Call)
