This week I was at DevSecCon in London to present my current research on Red Hat OpenShift. In this talk, I gave a brief introduction to OpenShift, demonstrated some threats that exist for such environments, and dived into different configuration issues that may affect the security of OpenShift environments. The implications of misconfigurations of such an environment have been shown in live demos.Continue reading

We are happy to announce that TROOPERS20 will feature the 5th anniversary of the popular Windows & Linux Binary Exploitation workshop!
In this workshop, attendees will learn how to exploit those nasty stack-based buffer overflow vulnerabilities by applying the theoretical methods taught in this course to hands-on exercises. Exercises will be performed for real world (32-bit) software such as the Foxit Reader Plugin for Firefox, Wireshark, and nginx.Continue reading
Also, with this blog post, we are releasing a Rekall plugin called pointerdetector that enumerates all exported functions from all DLLs and searches the memory for any pointer to them (essentially a search for dynamically resolved APIs). This plugin can assist in identifying dynamically resolved APIs and especially memory regions containing DLLs loaded with techniques such as reflective DLL injection. This blog post will contain some examples illustrating the usage of this plugin, as well.Continue reading
The Windows Insight repository now hosts three articles on Windows code integrity and WDAC (Windows Defender Application Control):
