A position-independent reflective loader for Cobalt Strike. Zero results from Hunt-Sleeping-Beacons, BeaconHunter, BeaconEye, Patriot, Moneta, PE-sieve, or MalMemDetect. AceLdr Demo

Import a single CNA script before generating shellcode.

Creates a new heap for any allocations from Beacon and encrypts entries before sleep.

Changes the memory containing CS executable code to non-executable and encrypts it (FOLIAGE).

Certain WinAPI calls are executed with a spoofed return address (InternetConnectA, NtWaitForSingleObject, RtlAllocateHeap).

Delayed execution using WaitForSingleObjectEx.

All encryption performed with SystemFunction032.

• Not compatible with loaders that rely on the shellcode thread staying alive.

This project would not have been possible without the following:

• FOLIAGE
• x64 return address spoofing (source + explanation)
