== Computer Virus Catalog 1.2: BYTE BANDIT PLUS Virus (5-June-1990) ===
Entry...............: BYTE BANDIT PLUS Virus
Alias(es)...........: ---
Virus Strain........: BYTE BANDIT Virus
Virus detected when.: September 1989
              where.: Elmshorn, FRG
Classification......: system virus (bootblock), resident
Length of Virus.....: 1. length on storage medium: 1024 byte
                      2. length in RAM           : 1024 byte
--------------------- Preconditions -----------------------------------
Operating System(s).: AMIGA-DOS
Version/Release.....: 1.2/33.166, 1.2/33.180 and 1.3/34.20
Computer model(s)...: AMIGA 500, AMIGA 1000, AMIGA 2000A, AMIGA 2000B
                         (and only with those memory expansions of
                          $0C000000 type)
--------------------- Attributes --------------------------------------
Easy Identification.: typical text: ---
Type of infection...: self-identification method: ---
                      system infection: RAM resident, reset resident,
                         bootblock
Infection Trigger...: reset (CONTROL + Left-AMIGA + Right-AMIGA)
                      operation: any disk access
Storage media affected: only floppy disks (3.5" and 5.25")
Interrupts hooked...: vertical blank interupt
Damage..............: permanent damage: overwriting bootblock, maybe
                         killing opened files when the screen and the
                         keyboard are shut off and the user has to
                         restart the computer using CONTROL+LEFT-AMIGA
                         +RIGHT-AMIGA keys; allocates available memory
                         minus 86016 byte
                      transient damage: screen buffer manipulation:
                         screen becomes dark, keyboard seems to mal-
                         function, transient damage may only be inter-
                         rupted by pressing a special key combination:
                         LEFT-ALT+LEFT-AMIGA (on newer AMIGAS the
                         COMMODORE key)+SPACE+RIGHT-AMIGA+RIGHT-ALT
                         (but the virus is still active )
Damage Trigger......: permanent damage: reset
                         operation: any disk access
                      transient damage: only under following condition:
                         2 resets AND 6 infections AND execution of
                         BYTE BANDIT's own interrupt routine 5208 times
                         (about 7 minutes)
Particularities.....: uses StartIOVector
                      other resident programs using the system resident
                         list (KickTagPointer,KickMemPointer) are shut
                         down
                      copy counter: 19th word
Similarities........: clone of BYTE BANDIT with some new code instead
                         of bootblock text, using undocumented system
                         adresses, manipulates background color, seems
                         to steel 86016 byte of system memory depending
                         from a counter at memory location $0007FC00
