Project Harvester

Project Harvester is a program created to control Linux systems remotely by uploading videos to Youtube.

The program monitors a Youtube channel until a video is uploaded, decodes the QR code from the thumbnail of the uploaded video and executes a command. The QR codes in the videos use AES-encrypted values.

Once the command has been executed, the output is exfiltrated over ICMP to our host server.
