Synonyms: Syslock, 3555
|
|||
|
|
|
|||
|
|
Host Machine: PC compatibles.
|
|||
|
|
|
|||
|
|
Host Files: Encrypting, non-resident. Infects COM, EXE files.
|
|||
|
|
|
|||
|
|
Increase in Size of Infected Files: 3551-3555 bytes.
|
|||
|
|
|
|||
|
|
Nature of Damage: Corrupts COM and EXE files. May corrupt data files.
|
|||
|
|
|
|||
|
|
Detected by: Scanv56+, F-Prot, Pro-Scan.
|
|||
|
|
|
|||
|
|
Removed by: CleanUp, Scan/D, or F-Prot.
|
|||
|
|
|
|||
|
|
Scan Code: Uses self-encryption.
|
|||
|
|
|
|||
|
|
When an infected program is run, SysLock searchs through the COM and
|
|||
|
|
EXE files and subdirectories on the current disk, picking one executable
|
|||
|
|
file at random to infect. The infected file will have its length
|
|||
|
|
increased by about 3,551 bytes.
|
|||
|
|
|
|||
|
|
The SysLock virus will damage files by searching for the word
|
|||
|
|
"Microsoft" in any combination of upper and lower case characters, and
|
|||
|
|
when found replace the word with either "MACROSOFT". If it finds an
|
|||
|
|
environment variable of "SYSLOCK" has been set to "@" (hex 40), the virus
|
|||
|
|
will not infect any programs or perform string replacements, but will
|
|||
|
|
instead pass control to its host immediately. The author may have used
|
|||
|
|
this during the creation of the virus.
|
|||
|
|
|
|||
|
|
One known variant is called Macho-A. It is identical to the SysLock
|
|||
|
|
virus, except that "Microsoft" is replaced with "MACHOSOFT".
