|
||
|
||
Date of Origin: September 30, 1989.
|
||
|
||
Place of Origin: Sofia, Bulgaria.
|
||
|
||
Host Machine: PC compatibles.
|
||
|
||
Host Files: Remains resident. Infects COM, EXE files.
|
||
|
||
OnScreen Symptoms: Plays "Yankee Doodle" on the system speaker some time
|
||
after loading.
|
||
|
||
Increase in Size of Infected Files: 2885 or 2899 bytes.
|
||
|
||
Nature of Damage: Affects system run-time operation. Corrupts COM and
|
||
EXE files.
|
||
|
||
Detected by: Scanv42+, F-Prot.
|
||
|
||
Removed by: CleanUp, Scan/D, VirClean, F-Prot, or delete infected files.
|
||
|
||
This virus was written by Wladimir Bochev from Sofia, Bulgaria, as an
|
||
intellectual exercise. It was discovered in Vienna by Alexander Holy at
|
||
the United Nation's North Atlantic Project office on Sept 30th, 1989.
|
||
The virus has reportedly been transmitted to the U.S. through U.N.
|
||
employees via the game "Outrun".
|
||
|
||
The virus plays the tune "Yankee Doodle Dandy" on the system's
|
||
speaker either when the program is loaded, or 17 hours after an infected
|
||
program is loaded, depending on the version of Yankee Doodle. Both COM
|
||
and EXE files of any size can be infected, and the virus willingly
|
||
infects every such file.
|
||
|
||
Infected files grow in size by 2899 bytes. Infected files can be
|
||
recognized by the string "motherfucker" at their ends. In the early
|
||
versions, there was no damage caused by the virus. In fact, the virus was
|
||
apparently designed as a virus fighter. It will seek out and modify Ping
|
||
Pong viruses, changing them so that they self-destruct after 100
|
||
infections. Subsequent strains may format the hard disk. Several
|
||
variations on the Yankee Doodle virus have been identified. See entries
