DoubleDrive ​

A fully-undetectable ransomware that utilizes Cloud Drive Services to encrypt target files. Presented at Black Hat USA 2023 Briefing under the title - One Drive, Double Agent: Clouded OneDrive Turns Sides

DoubleDrive Python Package ​

(Tested only on python version 3.11.4)

Implements most of the logic and tools that a DoubleDrive variant needs. In order to create a DoubleDrive variant for a certain cloud storage service, the creator must create 2 different executables using this library's tools:

• An endpoint takeover executable, implements:
  • Undetectable legitimate logic that syncs local target paths from the target computer to the cloud storage service using a built-in feature of the local cloud storage app
  • Exfiltration of the stolen authentication information so the target local paths become accessible from the cloud storage service API
• A DoubleDrive ransomware executable, implements:
  • Collection of the exfiltrated authentication information that was sent by the endpoint takeover executable
  • Encryption of all target files by sending API requests to the cloud storage service
