Name : Darth Vader
Aliases : No Aliases
Type/Size : File/784
Clones : No Clones
Symptoms : No Symptoms
Discovered : -
Way to infect: File infection
Rating : Less Dangerous
Kickstarts : 1.2/1.3 without Fastmem
Damage : Sometimes Startup-Sequence damage.
Removal : Delete File.
Comments : The Darth Vader virus is very LAME coded. The virus
allocates 1100 bytes memory. Then it copies itself
into this address and changes the CoolCapture-Vector
to stay resident in memory.
To infect other disks the virus patches the OldOpenLib
Vector. If a program now uses the OldOpenLib-Vector
the does the following:
1) Creates a invisible file ($A0) in the Root-Dir of
the actual disk.
2) Then it modifies the Startup-Sequence with the
virus name.
But this routine has a big bug which can damage
your startup-squence:
- The virus only loads/saves 1000 bytes.
- If the Startup-Sequence is longer than 1000
bytes, it will be damaged...
On every 5.th infection the virus gives out a CLI
Message:
"VIRUS (V1.1) BY DARTH VADER"
