---------------------------------------------------------------------- [1.4] Ideas For Future Viruses 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!  Downloaded From P-80 International Information Systems 304-744-2253
