| Alias: | lamer_bomb, MINIDEMO.EXE |
| Strain: | LamerLink |
| detected when: | unknown |
| where: | unknown |
| Classification: | link virus (Extending), not resident |
| Length: | 1. length on medium: a) MINIDEMO.EXE file: 773 byte b) infected files are 372 bytes longer 2. length in RAM: 1000 byte |
Preconditions | |
| Operating System(s): | AMIGA-OS |
| Version/Release: | 1.2/33.166, 1.2/33.180, 1.3/34.20 |
| Computer model(s): | AMIGA 500, AMIGA 1000, AMIGA 2000 |
| Caroname: | LamerLink.gotcha_lamer |
Attributes | |
| Easy identification: | typical text: 'HAHAHE... Gotcha LAMER!!!' |
Type of Infection: | a) linking virus into: dh0:c/dir dh0:c/run dh0:c/cd dh0:c/execute b) DoIO calls hocked |
| Infection Technique: | |
| Infection Trigger: | a) starting the virus dropper MINIDEMO.EXE b) starting infected dir, run, cd, or execute |
| Storage Media affected: | a) harddisk dh0: b) only floppy disks |
| Interrupts hooked: | Trap 0 is hooked directly before the virus RESETS the computer. |
| Stealth: | |
| Tunneling/Selfprot: | |
| Oligo/Polymorphism: | |
| Encoding Method: | |
| Damage: | Overwrites disk (81 tracks!) with senseless datas, shows ALERT (text see under: Easy Edentification), and RESETS the computer. |
| Damage Trigger: | Performing DoIO call for reading $200 bytes from the BootBlock of an unwriteprotected disk. |
| Particularities: | Newer versions of the AmigaOS CLI/shell have the named commands build in, in this systems the virusdropper will not work. Systems having their commands in a different directory (like all disk- based systems) will not be infected, too. I ask myself why the viruswriter use "dh0:c/" and not "c:" ? |
