-
- We have received a trojan horse version of VIRUSCAN. The hacked SCAN has
- apparently been uploaded to BBSes in Michigan, USA under the filename
- SCANV78.ZIP. Running PKZIP -V on the file reveals:

- The number listed for the Fantasia BBS is NOT a BBS number and has no
- connection with the trojan horse. I have called the phone number and asked
- the party at the other end to contact me.
-
- Running PKUNZIP on the file reveals the following:
-
- .PKUNZIP (R) FAST! Extract Utility Version 1.1 03-15-90

-
- While the Authentic Files Verified Message appears, the Serial Number is NOT
- correct. McAfee Associate's Serial Number is NWM405.
-
- Examination of the AGENTS.TXT, README.1ST, VALIDATE.*, and VIRLIST.TXT files
- revealed that these are straight from VIRUSCAN Version 77--the version number
- in the VIRLIST.TXT file was still V77.
-
- The SCAN78.DOC file had been modified so that all occurrences of V77 were
- switched to V78. Additionally, the following text was added for the
- validation data:
-
- . The validation results for Version 77 should be:
- .
- . FILE NAME: SCAN.EXE
- . SIZE: 23,008
- . DATE: 05-06-1991
- . FILE AUTHENTICATION
- . Check Method 1: 2C21
- . Check Method 2: 022E
- .
-
- For the What's New section, the following text was added:
-
- . WHAT'S NEW
- . Version 78 of SCAN removes a few small bugs and continues
- . to optimize the procedures SCAN uses to find viruses, as in Version 77,
- . as well as adding a few more to the list of known viruses. SCAN is now
- . much more compressed than was previously thought possible, so please enjoy
- . the shortened file size, it should still work just fine.
-
- . Refer to the enclosed VIRLIST.TXT file for a schematic
- . description of the new viruses. For a complete description, please
- . refer to Patricia Hoffman's VSUM document.
- .
- Examination of the SCAN.EXE file has show that it contains the help message
- that VIRUSCAN displays as well as the program information message. However,
- the program does not contain any of the other messages that VIRUSCAN has in
- it.
-
- The REGISTER.DOC file distributed with the trojan version of VIRUSCAN is not
- a text file, but rather another .ZIP file containing a file named TB1.COM:
-
- . PKUNZIP (R) FAST! Extract Utility Version 1.1 03-15-90
- . Copr. 1989-1990 PKWARE Inc. All Rights Reserved. PKUNZIP/h for help
- . PKUNZIP Reg. U.S. Pat. and Tm. Off.
- .
- . Searching ZIP: REGISTER.DOC
- . Extracting: TB1.COM -AV
- .
- . Authentic files Verified! # TJB859 Zip Source: McAFEE ASSOCIATES
- .
-
- When unZIPped, the REGISTER.DOC file displays the same Authentic Files
- Verified Message as the SCANV78.ZIP file did. Examination of the of the
- TB1.COM file revealed that it contains the Whale virus.
-
- This is all I currently know about the SCANV78.ZIP trojan. If you see any
- copies of this file, please ask the system administrator or sysop to remove
- it and ask them to contact the uploader to warn them that it contains a
- virus.
