uid0000 / Amber

Reflective PE packer.

amber is a reflective PE packer for bypassing security products and mitigations. It can pack regularly compiled PE files into reflective payloads that can load and execute itself like a shellcode. It enables stealthy in-memory payload deployment that can be used to bypass anti-virus, firewall, IDS, IPS products and application white-listing mitigations. If you want to learn more about the packing methodology used inside amber check out below. For more detail about usage, installation and how to decrease detection rate check out WIKI.
