Extracting PEAP Credentials from Wired Network Profiles
#itm4n

Naturally, he wanted to extract those credentials. Nothing extraordinary about that you might think, and yet, there was a twist… Where to start? For this blog post, I will assume the reader is a...

Behind the Code: Assessing Public Compile-Time Obfuscators for Enhanced OPSEC
#trustedsec

Recently, I’ve seen an uptick in interest in compile-time obfuscation of native code through the use of LLVM. Many of the base primitives used to perform these obfuscation methods are themselves over a year old, and…

Easy cross compilation - zig
#tool #maldev

Sometimes on engagement you need to cross compile your c(++) tools, but doing it is a headache because of lots of compilers you need for every OS and architecture. I found an interesting way to do it using only one tool: Zig compiler.

Leveraging the ability of LLVM and integrated cross-os and cross-architecture support built-in to the Zig compiler, you can cross compile for lots of OS and architectures.

Here is an example for cross compiling for x64 Windows, Linux and OSX:
👉zig c++ -target x86_64-macos hello_world.cpp -o hw_mac.out
👉zig c++ -target x86_64-linux hello_world.cpp -o hw_lin.out
👉zig c++ -target x86_64-windows hello_world.cpp -o hw_win.out

Also it can be integrated into your build system (e.g. CMake or Makefile):
👉CC="zig cc -target x86_64-macos" CXX="zig c++ -target x86_64-macos" AR="zig ar" RANLIB="zig ranlib" USE_JEMALLOC=no USE_SYSTEMD=no

In addition, you also can easily leverage a power of LLVM obfuscators (e.g. https://github.com/eshard/obfuscator-llvm) to make it harder to analyze your malware.

Btw, don't forget to strip your binary 😉
