- Subject: Fred Cohen's papers...
-
- The question came up recently about Fred Cohen's papers and how to
- obtain them. The address in Pittsburgh is correct (Fred Cohen, c/o P.
- O. Box 90069, Pittsburgh, Pennsulvania 15224). The cost (for those
- who have misplaced the message from December) is $20 for Fred's
- thesis, and $20 for the assorted articles.

- Subject: re: Yale virus = Alameda virus (PC)
-
- The "Yale" virus indeed does not work on 20286 machines, in the sense
- that if one tries booting a 20286 machine with an infected disk the
- machine will hang. In effect, the ONLY active part of the machine at
- that point is the virus -- if you then do Ctrl-Alt-Del with a
- non-write-protected disk in the A drive, that diskette will get
- infected. On a PC, if you boot from an infected disk, the virus is
- loaded into memory and will infect other disks upon soft-boot, but
- otherwise it is completely transparent and is not likely at all to be
- discovered. The only reason we caught it at Yale is that all our
- machines are 20286 machines, and we were suddenly faced with machines
- not booting properly. The person who we suspect brought the virus to
- Yale (unknowingly) insisted at the time that his disk, which was not
- working properly at our public facilities, was working perfectly at
- his home and elsewhere. He was using ordinary PCs at these places. I
- have also verified this effect myself using an authentic copy of the
- "Yale" virus.
-
- I personaly am convinced that the Yale virus is the same as the
- Alameda virus.
-
- Thanks,

- Subject: Disinfectant 1.1 (Mac)
-
- Disinfectant Version 1.1 Announcement & Press Release.
-
- April 16, 1989.
-
- Disinfectant 1.1 is a new release of a program to detect and remove
- Macintosh viruses.
-
- Version 1.1 recognizes the new MEV# virus that was discovered in
- Belgium a few weeks ago. Version 1.1 also fixes a few bugs and adds
- several new features. For a detailed list of all the changes see the
- new section titled "Version History" in the online document.
-
- We recommend that all Disinfectant users obtain a copy of the new
- version.
-
- With version 1.1 we are also now distributing a formatted version of
- the document, with screen shots and other pictures, a table of
- contents, etc. See the online document for details on how to obtain a
- copy.
-
- Version 1.1 has been posted to CompuServe, AppleLink,
- comp.binaries.mac, and info-mac. It should be available from those
- sources soon, as well as from many other bulletin boards, commercial
- online services, user groups, and Internet archive sites.
-
- Features:
-
- - - Detects and repairs files infected by Scores, nVIR A, nVIR B, Hpat,
- AIDS, MEV#, INIT 29, ANTI, and MacMag. These are all of the currently
- known Macintosh viruses.
- - - Scans volumes (entire disks) in either virus check mode or virus
- repair mode.
- - - Option to scan a single folder or a single file.
- - - Option to "automatically" scan a sequence of floppies.
- - - Option to scan all mounted volumes.
- - - Can scan both MFS and HFS volumes.
- - - Dynamic display of the current folder name, file name, and a thermometer
- indicating the progress of a scan.
- - - All scans can be canceled at any time.
- - - Scans produce detailed reports in a scrolling field. Reports can be
- saved as text files and printed with an editor or word processor.
- - - Carefully designed human interface that closely follows Apple's
- guidelines. All operations are initiated and controlled by 8 simple
- standard push buttons.
- - - Uses an advanced detection and repair algorithm that can handle partial
- infections, multiple infections, and other anomalies.
- - - Careful error checking. E.g., properly detects and reports damaged and
- busy files, out of memory conditions, disk full conditions on attempts
- to save files, insufficient privileges on server volumes, and so on.
- - - Works on any Mac with at least 512K of memory running System 3.2
- or later with HFS.
- - - Can be used on single floppy drive Macs with no floppy shuffling.
- - - 11,000 word online document describing Disinfectant, viruses in
- general, the Mac viruses in particular, recommendations for "safe"
- computing, Vaccine, and other virus fighting tools. We tried to
- include everything in the document that the average Mac user needs to
- know about viruses.
-
- I wrote Disinfectant with the help of an international group
- of Mac virus experts, programmers and enthusiasts: Wade Blomgren,
- Chris Borton, Bob Hablutzel, Tim Krauskopf, Joel Levin, Robert Lentz,
- Bill Lipa, Albert Lunde, James Macak, Lance Nakata, Leonard Rosenthol,
- Art Schumer, Dan Schwendener, Stephan Somogyi, David Spector, and
- Werner Uhrig.
-
- These people helped design and debug the program, edit the document,
- locate copies of the viruses for testing, and analyze the viruses. I
- wrote all the code, but I could not have written the program without
- their help.
-
- Disinfectant is an example of a new kind of cooperative software
- development over the internet. It was developed over a period of three
- and one half months starting on December 1, 1988. During this period I
- sent out nine development releases and nine Beta releases to the
- working group, and we exchanged several hundred notes. The result is a
- program that is much better than any one of us could have produced
- individually.
-
- We are offering this program free of charge as a public service. We
- hope that the Mac community finds it useful.

- Subject: Re: More on Yale virus (PC)
-
- The Yale virus (at least the one I have!) does contain a "POP CS".
- Mr. McAfee is oversimplifying slightly again; "POP CS" is a perfectly
- valid instruction on '286 machines in real mode (which is how DOS
- runs). It's just not a valid instruction in protect mode (which is
- how OS/2 runs, for instance). I'm not quite clear on when in the boot
- cycle an OS/2 machine enters protect mode; in any case, the virus does
- contain "POP CS", but that's consistent with your having seen it on
- ATs.

- Subject: Information wanted on "Stoned" virus (PC)
-
- Has anyone encountered a virus that writes the message "Your PC is now
- Stoned! LEGALISE MARIJUANA!" in the boot sector of an infected floppy?
- Any information would be appreciated.

- Subject: re: computers & media piece on virus-l
-
- Dear Dimitri,
-
- Hi. I just read your posting. It is very insightful and interesting.
- It is unfortunate that there is no practical way for those of us who
- 'understand' the issues to serve as editors-in-chiefs for all
- publications of this type.
-
- This serves as another facet of problems with the media. Presumably,
- the author of the article has some expertise. But even if he doesn't,
- the reader will still place (undue) reliance upon his statements.
-
- For some problems, unfortunately, there is no easy solution.
-
