Remote-Desktop-Caching : Recover Old RDP (MSTSC) Session Information In The Form Of Broken PNG Files

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

Choosing Option 4: Starts analyzing cache files and reconstruction process. This option creates a folder in user C drive with a name of Recovered_RDP_Sessions

Sensitive information is recovered from these binary files in the form of broken PNG images. Managed to recover LAPS password, Attacker IP address and malicious file names. It also reveals some of the crucial information about attacker activities on a compromised host. For forensics team timestamp is revealed in most of these recovered images.
