Technical Details


Infection

Rogue turns off VSAFE protections while infecting files. Unlike most other viruses, Rogue turns the protection back on after infection is done. It also deletes MSAV's CHKLIST.MS files. Rogue has stealth features, as it is able to hide the size increase of infected files when the user attempts to view the file using the DIR command.

Activity

Rogue activates on the 14th of March. On this date it corrupts DBF database files when they are accessed and randomly reboots the PC.
