The Pirate 1344 virus was received in October, 1993. Its origin or
point of isolation is unknown. Pirate 1344 is a memory resident
infector of .EXE programs.
When the first Pirate 1344 infected program is executed, this virus
will install itself memory resident at the top of system memory but
below the 640K DOS boundary, not moving interrupt 12's return.
Total system and available free memory, as indicated by the DOS
CHKDSK program, will have decreased by 1,344 bytes. Interrupts 09
and 21 will be hooked by the virus in memory.
Once the Pirate 1344 virus is memory resident, it will infect .EXE
programs when they are executed. Infected programs will have a
file length increase of 1,344 to 1,358 bytes with the virus being
located at the end of the file. The program's date and time in the
DOS disk directory listing will not be altered. The following text
string is visible within the viral code in all Pirate 1344 infected
Characters from system memory may occassionally be displayed on the
system monitor on infected monochrome systems. Execution of some
programs may fail with the following message:
"Program too big to fit in memory"
