The Cece virus was received in July, 1995. Its origin or point of
isolation is unknown. Cece is a memory resident infector of .COM
and .EXE files, including COMMAND.COM.
When the first Cece infected program is executed, this virus will
install itself memory resident at the top of system memory but
below the 640K DOS boundary, hooking interrupts 01, 21, and 24.
Available free memory, as indicated by the DOS CHKDSK program from
DOS 5.0, will have decreased by 5,120 bytes. Interrupt 12's return
will not have been moved.
Once the Cece virus is memory resident, it will infect .COM and
.EXE files when they are executed or opened, but not on copy.
Infected programs will have a file length increase of 1,994 bytes
with the virus being located at the end of the file. The file's
date and time in the DOS disk directory listing will not appear to
be altered, though the years field may appear to have 36 years
added to the file date. The following text strings are encrypted
within the viral code:
"Welcome to presentation of new program, named Ce-Ce!!!"
"Can you recognize what does it mean?"
"1. Do you know the fly living in the Africa?"
"2. Do you know int3 command opcode?"
"3. Do you know that 0CCh is equal to 204?"
"4. Do you know that CC is Computer Center abriviature?"
"5. Do you know the name of main hero in Santa Barbara?"
"Do you know ..."
System hangs may occur when some programs are executed.
