Since I have covered viruses already in existence, lets talk
about viruses that can or may exist in the near future. These are not
even close to half the ideas possible for destruction with
trojans/viruses available, but will pose as a challenge to you who
are short of ideas.
CSR Virus - A CMOS Stay Resident VIRUS that will implant itself
in the CMOS memory of the AT (286/386/486?) which will execute upon
every bootup. This one would be VERY nice.
Failsafe Virus - Preserves ALL attributes, Preserves file size,
remains TSR but hidden to TSR location programs, Modifies attributes
to get around Read-Only files, Infects ALL files (Not only COM and
EXE), encrypts all data on trigger (irreversible) but preserves
original file size/attributes.
Format Virus - A virus which is TSR and when a DOS format or any
other FORMAT type of call is called, will FORMAT every other track,
but will not allow DOS to notice.
Write Virus - A virus that intercepts write to disk, which
deletes the disk write, and marks sector as bad at write point.
ASCII Virus - Virus that would scramble ASCII text in any file
at trigger.
Low Level Format Virus - Virus that low level formats (BAD
format) HD in background with data still intact. I have seen regular
background LLF programs, and it keeps data in place, but it does it
correctly... hmmm...?
Hide Virus - A Virus that hides files slowly.
Crash Virus - Virus that emulates typical system crashes/freezes
occasionally. Causes BIOS to freeze and write BIOS ERROR messages on
screen.
Modem Virus - One that remains in boot sector and TSR and
monitors data from serial ports, puts in "artificial" line-noise.
NICE!
These are just a few I thought up... these could be really
good... Think of some more and call CPI HQ TODAY!
