Bypassing Antivirus using Amber (Reflective PE Packer)

Amber is a proof-of-concept tool used for bypassing antivirus software. Amber uses techniques that convert Portable Executables (PEs) to reflectively load those PEs. This can be used as a multi-stage payload for infection on a target system. Amber takes advantage of in-memory execution methods. In-memory fileless execution can be defined as executing a compiled PE inside the memory, without actually writing data to storage. This results in fewer footprints, as the malware does not leave a file on the hard drive.
