In my previous post “Red Team Tactics: Utilizing Syscalls in C# - Prerequisite Knowledge”, we covered some basic prerequisite concepts that we needed to understand before we could utilize syscalls in C#. We touched on some in-depth topics like windows internals and of course syscalls. We also went over how the .NET Framework functions and how we can utilize unmanaged code in C# to execute our…
Over the past year, the security community - specifically Red Team Operators and Blue Team Defenders - have seen a massive rise in both public and private utilization of System Calls in windows malware for post-exploitation activities, as well as for the bypassing of EDR or Endpoint Detection and Response.
Happy Holidays and a Happy New Year 2020 readers!
On August 22, 2019 I received yet another one of the most desired emails by aspiring Offensive Security enthusiasts and professionals…
In my previous post “Google CTF (2018): Beginners Quest - PWN Solutions (1/2)”, we covered the first set of PWN solutions for the Beginners Quest, which touched on topics such as code injection, reverse engineering, buffer overflows, and format string exploits.
