Remote Desktop Caching : Tool To Recover Old RDP

Remote Desktop Caching tool allows one to recover old RDP (mstsc) session information in the form of broken PNG files. It is extremely useful for a forensics team to extract timestamps after an attack on a host to collect evidences and perform further analysis.

These PNG files allows Red Team member to extract juicy information such as LAPS passwords or any sensitive information on the screen. Blue Team member can reconstruct PNG files to see what an attacker did on a compromised host.
