This is a Beacon Object File to refresh DLLs and remove their hooks. The code is from Cylance's Universal Unhooking research:

https://blogs.blackberry.com/en/2017/02/universal-unhooking-blinding-security-software

To use:

Load unhook.cna into Cobalt Strike via Cobalt Strike -> Script Manager

Run 'unhook' from Beacon

The Sliver Armory package uses the built-in Reflektor BOF executor. It requires
a Sliver client, server, and Windows implant with BOF v1 support; the package
does not install COFFLoader as a fallback. The optional skipmodule argument is
a comma-separated list of DLL names to leave unchanged.

To build:

make
