- *** Macintosh INIT 1984 Virus Discovered ***
-
- Virus: INIT 1984
- Damage: high
- Spread: minimal
- Systems affected: Apple Macintosh computers. All types.
-
- A new virus, which has been designated "INIT 1984", has been
- discovered on Apple Macintosh computer systems. This virus is designed
- to trigger if an infected system is booted on any Friday the 13th in
- 1991 or later years. Damage from the virus includes changing the names
- and attributes of a large number of folders and files to random
- strings and the actual deletion of a small percentage (< 2%) of files.
-
- The virus infects only system extensions of type "INIT" (also known as
- "startup documents"). It does not infect the System file, desktop
- files, control panel files, applications, or document files. Because
- INIT files are shared less frequently than are applications, and
- because of the structure of the virus code, the INIT 1984 virus does
- not spread as rapidly as most other viruses.
-
- As of the date of this announcement (3/19/92), we have only a few
- reported sightings of this virus, including one from a site in Europe
- and one from a site in the USA. In both cases, the virus caused
- significant damage when infected Macintoshes were restarted on Friday,
- 3/13/92. Because only a few reports of damage were received, we have
- reason to believe that the virus is not widespread. However, it is
- conceivable that this virus might have affected Macintosh systems on
- Friday 9/13/91 or Friday 12/13/91 without being recognized as the
- cause of the damage. If you think you may have been a victim of this
- virus in 1991, please contact me via e-mail at spaf@cs.purdue.edu.
-
- The current versions of Gatekeeper and SAM Intercept (in advanced and
- custom mode) are effective against this virus. Either program should
- generate an alert if the virus is present and attempts to spread to
- other files.
-
- The virus affects all types of Macintosh computers. It spreads and
- attacks under both System 6 and System 7. On very old Macintoshes
- (those with the 64K ROMs), the virus will cause crashes at boot time.
-
- Authors of all major Macintosh anti-virus tools are planning updates
- to their tools to locate and/or eliminate this virus. Some of these
- are listed below. We recommend that you obtain and run an updated
- version of at least one of these programs.
