Articolo scritto da Faber Pixel

Amiga Virus - Revenge of the Lamer Exterminator

Scheda

Nome: Revenge of the Lamer Exterminator virus
Tipologia: Link Virus

Effetti:
Programmazione complessa. Lunghezza: 4560 byte.
Agisce su AvailMem, Kicksumdata, Kicktagptr, interrupt raster, BeginIO,DoIO, OpenWindow (Intuition), CloseDevice.
Il virus è codificato da una chiave casuale. Si installa all'inizio della startup-sequence.
Il suo nome è: $a0a0a0a0a0 (invisibile).

Poiché si installa senza utilizzare la funzione DOS sul disco, non è rilevabile in una directory, neanche con List.
È trasparente alla memoria ingannando le informazioni fornite da AvailMem seppur occupando $12c0 byte in ram.
Una volta attivato, cancella irrimediabilmente i dischi trovati in tutte le unità collegate contemporaneamente in meno di 3 secondi.
Il virus utilizza la velocità del formato MFM. I dischetti non possono nemmeno neanche essere letti parzialmente con un Hex editor. Possono essere riutilizzati solo dopo la riformattazione.
Utilizza una libreria DOS interna e quindi offset scarsamente documentati e utilizza funzioni quasi sconosciute tipo: execbase-630!
Visualizza il seguente testo dopo aver cancellato i dischi e resettato:
