Recent supply chain attacks have demonstrated that the most valuable targets are developers 🧑‍💻

In this new blog post, I'll walk you through the full setup of a phishing attack 🎣 (ab)using GitHub OAuth App to gain control over an account! Trusted domains, free infrastructure, social engineering tricks, ...

P.S: I've updated the blog design ✨, hope you enjoy it

New research: InsomniacUnwinding
"Call stack spoofing is mandatory for sleep masking"
No, it's not. Surgical UNWIND_INFO preservation: ~250 bytes vs ~6KB .rdata. Signatures encrypted, stack intact, no spoofing.

🚨 ProxyBlob update just dropped 🚨

This cute little blob become even more versatile, as it can now be compiled into WASM 📦 It won't work in your browser, but it will certainly run in JavaScript runtimes such as Node.js, Bun, Deno, etc.

🥳 ProxyBlob V2 is now available 🎉

As promised, here is the new version of ProxyBlob, boosted with aznet. Az-what 🤔?

This version introduces a new Go module called aznet that allows you to use Azure storage services (not just blobs 😏) as a direct replacement for net.Conn!

Complete documentation is available in the aznet repo to understand how it works 📚

Huginn Project:
Project to generate COFF-format shellcode with API for :
- Indirect syscall API
- Stack Spoofing
- Proxied LoadLibraryA calls

Great for UDRLs, stage0 and OPSEC-conscious shellcode.

Even if stealth wasn't the objective, I still wanted to test the next release during my engagement. I must say that I'm very happy with the costs incurred 💸 This is the result of a large number of actions, which led to a massive DCSync with ~ 20k hashes 🎯

Hi, I just pushed an update on OdinLdr.

I have added an EAF Bypass to resolve function addresses, NtApi calls are now made with indirect syscall and synthetic stackframe.

Majority of code is rewritted to be more clean

WSL2 is a powerful attacker hideout because it runs as a separate Hyper-V VM, and defenders rarely monitor it.

Daniel Mayer explains how attackers pivot into WSL2 and what it took to build tooling that works across WSL2 versions.

@Cyb3rMonk @magnetgang With an executable in C like printspoofer for example, you can allocate a memory region, you write the file in this region, you patch and you run it by jumping to the entry point

Santa's dropping a new BOF down the chimney!

My Christmas gift to RedTeam operators: BOF_ExecuteAssembly

[Rtl Dallas @RtlDallas]

@Cyb3rMonk @magnetgang You can do module stomping for an unmanaged process (C/C++ for example) but for an assembly when you load it with Load_3 the bytecode (assembly data) needs to be in SafeArray.

@Jean_Maes_1994 Thanks :)

[Rtl Dallas @RtlDallas]

@Jean_Maes_1994 Yes, all code : Donut, InlineExecute-Assembly, implementation in NH or BRC4 use the same method to run assembly and receive output. The big difference is in the implementation and in particular with evasion.

[Rtl Dallas @RtlDallas]

@Jean_Maes_1994 I don't understand sorry 😅

[Rtl Dallas @RtlDallas]

@harold9850 Hi, I tested my BOF on a VM with CrowdStrike and it works, BUT it's not a silver bullet. The results can differ depending on the assembly's behaviors, potential presence of custom rules by BT, execution conditions, ...

[RELEASE] As promised, I’m releasing the first blog post in a series. It covers the gaps still present in current stack-based telemetry and how Moonwalking can be extended to evade detection logic and reach “on-exec” memory encryption.
Enjoy ;)
