[comp.virus] Virus-Construction-Set

jaenichen@rz.informatik.uni-hamburg.dbp.de (Matthias Jaenichen) (03/18/91)

On the Hannover-fair "CeBit" a Virus-Construction-Set for MS-DOS was
found in a BBS. The BBS is a German system called "ZERBERUS". The
program was uploaded in Hamburg. The Box-Sysops are informed and will
(hopefully) delete the entries.

It is possible to build a virus that will display a massage at a
selectable generation-count. At the same time the files "CONFIG.SYS"
and "AUTOEXEC.BAT" will be deleted.

The virus will be given the name "VCS-1.0".
The virus extends programs by 1077 Bytes.
The following string can be found at offset 50h:"A5 A5 A4 68 00 C1 C3 8A"
At the end of the virus "C:\AUTOEXEC.BAT" and "C:\CONFIG.SYS"

Codeanalysis will begin soon after the fair.
