====================== BULLETIN #1 =======================
|
||
The following 2 Articles I got from 2 magazines (I will give the reference
|
||
at the end of the article), and I thought that you might like to see this.
|
||
|
||
|
||
WARNING!
|
||
|
||
Warning: Someone is trying to destroy your data. Beware of the SUDDEN upsurge
|
||
of "Trojan Horse" programs on Bulletin Boards and in the public domain. These
|
||
programs purport to be useful utilities, but, in reality, they are designed to
|
||
sack your system.
|
||
One has shown up as EGABTR, a program that claims to show you how to maximize
|
||
the features of IBM'S Enhanced graphics Adapter, and has also been spotted as
|
||
a new super-directory program. It actually erases the file allocation tables
|
||
on your hard disk. For good measure, it asks you to put a disk in Drive A:,
|
||
then another in Drive B:. After it has erased those FATs too, it displays,
|
||
|
||
" Got You! Arf! Arf! "
|
||
|
||
Don't run any public-domain program that is not a known quantity. Have someone
|
||
you know and trust vouch for it. ALWAYS examine it FIRST with DEBUG, looking
|
||
for all the ASCII strings and data. If there is anything even slightly
|
||
suspicious about it, do a cursory disassembly. Be wary of disk calls
|
||
(INTERRUPT 13H), especially if the program has no business writing to the disk.
|
||
Run your system in Floppy only mode with write protect tabs on the disk or junk
|
||
disks in the drives.
|
||
Speaking of Greeks bearing gifts, Aristotle said that the unexamined life is
|
||
not worth living. The unexamined program is not worth running.

|
||
|
||
Another bit of information I got from the ARPANET: Be careful what you put into
|
||
your machine. There is out there making the rounds of the REMOTE BULLETIN
|
||
BOARDS a program called VDIR.COM. It is a little hard to tell what the
|
||
program is suppose to do.
|
||
What it actually does is TRASH your system. It writes garbage onto ANY disk it
|
||
can find, including hard disks, and flashes up various messages telling you
|
||
what it is doing. It's a TIME BOMB: once run, you can't be sure what will
|
||
happen next because it doesn't always do anything immediately. At a later
|
||
time, though, it can CRASH your system. Does this remind you of some of the
|
||
imbecilic copy-protection schemes threatened by companies such as Vault and
|
||
Defendisk? Anyway, you'd do well to avoid VDIR.COM. I expect there are a
|
||
couple of harmless-perhaps even useful-Public Domain programs floating about
|
||
with the name VDIR; and, of course, anyone warped enough to Launch this kind
|
||
of Trap once, can do it again. Be careful about untested "Free" software.

Well there it is, If you happen to see any of these files on this, or any other
|
||
RBBS, IBBS, FIDO or any other board, PLEASE leave the SYSOP a message or a
|
||
and let him know about the file. I will List 2 other Files that I am aware of
|
||
that will also do damage as has been reported in the past:
|
||
1. STAR.EXE presents a screen of stars then copies RBBS-PC.DEF
|
||
and renames it. The caller then calls back later and d/l the
|
||
innocently named file, and he then has the SYSOP'S and all the
|
||
Users passwords.
|
||
|
||
2. SECRET.BAS This file was left on an RBBS with a message saying
|
||
that the caller got the file from a mainframe, and could not get
|
||
the file to run on his PC, and asked someone to try it out.
|
||
When it was executed, it formatted all disks on the system.
|
||
|
||
We must remember, that there are a Few idiots out there who get great pleasure
|
||
from destroying other peoples equipment. Perverted I know, but we, the serious
|
||
computer users must take an active part in Fighting against this type of stuff,
|
||
to protect what we have. Be sure to spread this bulletin to other Boards
|
||
across the country so that as many people as possible will be aware of what is
|
||
going on. Thanks alot!
