PACKDIR: Is supposed to pack files
on a hard drive, but it also scrambles
FATs.
QUIKRBBS.COM: Claims to speed
the load of RBB5-PC's message file.
Doesn't work.
QUIKREF: Contains ARC513.COM.
RCKVIDEO: Displays simple animation of a rock star, then erases files.
SECRET.BAS: Disk formatter.
SIDEWAYS.COM: The good version
prints text sideways; the other version
trashes the hard disk's boot sector.
SIDEWAYS.COM, about 3K, is the
trojan. SIDEWAYS.EXE, about 30K, is
legitimate.
STRIPES.EXE:
Puts
STAR.EXE,
graphics on the screen, all the while
copying RBB5-PC.DEF into another
filename which a snoop can download
later to get passwords.
TOPDOS: A high-level hard disk formatter.
VDIR.COM: The disk killer which
Pournelle described in Byte.
There are no doubt many more.
Anyone who can RENAME a file can
RENAME a new trojan.
Buggy Programs
Of course, there are lots of buggy
programs out there and it's nice to
know which ones can fail in destructive
ways, but don't assume every bad ending is the result of a trojan. (Hardware
can act strangely, too.) Trojan stories
spread faster than trojan programs, so
be a little leery of undocumented
reports (including the ones here).
Also, be aware that stacked TSR (ter-
minate and stay resident) programs can
make a system overly sensitive to
program strangeness. Be sure your system is clean before you write off a new
utility.
The above list of trojans was taken
from the file DIRTYDZ7.ARC, put
together by Eric Newhouse. (He keeps
the file updated so watch for DIRTYDZ8.ARC.)
If you find an honest to gosh trojan,
send it in. If you know who wrote it
and why, tell us. Also, be sure to contact Eric Newhouse on his bulletin
board at 213-471-2518 (1200-2400), so
he can add your findings to DIRTYDZ.
And, if you see a very large horse
standing outside your city's wall ....
