Threat Description



Aliases: Flame, Stamford
Category: Malware
Platform: W32


Stoned.Flame is a newer version of the Stoned virus but does not contain any significant improvements.Like the original Stoned virus, Stoned.Flame infects hard disk MBR's and floppy boot sectors. The special thing about this virus is that it always saves the original boot sector in the same spot on the disk, no matter what the disk type is. This causes data corruption on some types of floppy disks.

After this it checks the month every time it is run. When the virus detects that the month has changed, it overwrites track 0 of the startup hard disk and displays a picture representing flames.Flame was reported to be in the wild in Finland in August 1993.
