Hacking and tracking correspondence.
How does it work?
To hack an account, the software exploits a data transmission protocol vulnerability caused by restoring account access. The application launches the account recovery process and intercepts an SMS message with a verification code. After gaining access to the Viber account database, the software logs into the compromised account on a virtual device, copies correspondence files, deploys them to the VBSpy interface, and starts background tracking of updates.
