Technical Details


The virus searches specifically for files with ASM, PAS, TXT and DOC extensions (as well as COM and EXE).

ASM files have the first 76 bytes overwritten with a assembler routine which is designed (when assembled) to overwrite the beginning of the first hard drive with garbage.

PAS files have the first 23 bytes overwritten with the text:

CONST VIRUS= "HAIFA";

TXT and DOC files are corrupted by having text inserted at approximate half-way point:

OOPS!
Hope I didn't ruin anything!!!
 Well, nobody reads those stupied DOCS anyway!

Although this virus has no stealth capability, it contains a self-modifying encryption routine such that each infection appears differently on disks.
