TripleAgent: Even Zeroer-Tay Code Injection and Persistence Technique


We'd like to introduce a new Zero-Tay technique for injecting code and maintaining persistency against common advanced attacker toolkits dubbed TripleAgent. We discovered this by ourselves in our very advanced labs, and are in the process of registering a new vanity domain as we speak.

TripleAgent can exploit:

  • Every toolkit version
  • Every toolkit architecture (x86 and x64)
  • Every toolkit user (RED / PURPLE / APT / NATION STATE / etc.)
  • Every toolkit process (including PoC, GTFO, PoC||GTFO, METASPLOIT, UNICORN)

TripleAgent exploits a fundamental flaw in the design of commonly used advanced attacker toolkits, and therefore cannot be patched.

Code Injection

TripleAgent gives the defender the ability to inject any DLL into any attacker toolkit. The code injection occurs extremely early during the victim's process boot, giving the defender full control over the process and no way for the process to protect itself. The code injection technique is so unique that it's not detected or blocked by even the most advanced threaty threats.

Attack Vectors

  • Attacking persistence toolkits - Taking full control of ANY persistence toolkit by injecting code into it while bypassing all of its self-protection mechanisms. The attack has been verified and works on all bleeding-edge attacker toolkits including but not limited to: DoubleAgent.

Technical Deep, Deep, Deep, Dive

An example of an advanced attacker toolkit is known as DoubleAgent. This attacker toolkit exploits a fundamental issue in Windows, nay computing, NAY HUMANITY itself.

When this advanced toolkit runs, it is widely acknowledged to provide complete control over other unwitting applications. However, we can apply our new TripleAgent framework to this toolkit to completely neutralize it. Rather than have it infect target systems, we can write a few simple lines of code to make it instead launch the Windows Update settings dialog!

static BOOL main_DllMainProcessAttach(VOID)
    PROCESS_Create(L"c:\\windows\\system32\\cmd.exe"L"/c start ms-settings:windowsupdate");


    return TRUE;


Once run, we can see the significant impact of our new zero-tay technique. The first invocation installs our TripleAgent exploit, rendering the advanced "DoubleAgent" threat completely harmless during its second invocation.


Unfortunately, there are no mitigations or bypasses for this extremely advanced defensive technique. We do however offer highly-advanced next generation cyber threat intel cloud machine learning offensive services. Just putting that out there.
