- The DDN SECURITY BULLETIN is distributed by the DDN SCC (Security
- Coordination Center) under DISA contract as a means of communicating
- information on network and host security exposures, fixes, and concerns
- to security and management personnel at DDN facilities. Back issues may
- be obtained via FTP (or Kermit) from NIC.DDN.MIL [192.112.36.5]
- using login="anonymous" and password="guest". The bulletin pathname is
- scc/ddn-security-yynn (where "yy" is the year the bulletin is issued
- and "nn" is a bulletin number, e.g. scc/ddn-security-9221).

- Virus Alert: "ALIENS 4"
-
- On Saturday, August 8 1992, what is believed to be a new "polymorhpic" or
- "adaptive" virus strain was detected on a Macintosh IIci running System 7
- at the Space Environment Lab in Boulder, Colorado.
-
- The NOAA/NIST staff working on the problem have been unable to identify this
- particular strain, so have given it the name "Aliens 4" because:
-
- (1) It's fast
-
- (2) It mutates
-
- (3) It likes to travel
-
- (4) Every time you think you've eradicated it, it pops up somewhere else.
-
-
- It is not known at this time whether the virus came in on an infected floppy
- or via Internet or DECnet. However, there is a strong suspicion that the virus
- can travel via networks.
-
-
- We also suspect that this virus is one of the new viral strains that can
- "mutate" into different forms, making it extremely dangerous because it is
- difficult (if not impossible) to trace and very difficult to eradicate.
-
- The investigation continues, but this is what has been found out so far:
-
- (1) It appears to infect System 7 Mac's easier than System 6.07 systems.
-
- (2) It appears as seemingly random system malfunctions (disk drives can't
- read disks, printer problems, uncommon desktop displays).
-
- (3) It does NOT appear to destroy files.
-
- (4) Symantec (and others) seem capable of detecting it, but unable to
- eradicate it completely.
-
- (5) It was first reported by anti-viral software as the nVIR A strain,
- then the MBDF A strain, and so on. For this reason, it has been
- identified as a polymorphic or adaptive filter.
-
- (6) The only 100% effective solution to date seems to be the "hard"
- re-formatting of infected disks.
-
- The point-of-contact for information about the ALIENS 4 virus is:
-
- Mr. Dave Bouwer
- dbouwer@selvax.sel.bldrdoc.gov
- (303) 497-3899
-
- If more concrete information on this virus becomes
- available, interested parties will be notified.
