[comp.sys.mac] Disinfectant 1.6 oddity

Adam.Frix@p2.f200.n226.z1.FIDONET.ORG (Adam Frix) (03/21/90)

For reasons no one cares about, I was fiddling around in Disinfectant
1.6 using Symantec Tools.  While in the resource fork, at sector 21, 
offset 97, I found the word "fuck" stuck in there.  Lowercase, all by
itself.  Now, this sounds real strange to me--I didn't expect this in this
product, and it really blew me away.  Does anybody know the source/
reason for this?  My main worry is that despite having gotten this copy
off of CompuServe (practically guaranteed, if not absolutely guaranteed,
clean), perhaps it's been altered by someone not authorized to alter it.
I don't mean to spread panic, but this is the first thing that came to
mind, and it's managed to stick with me.

Any help is appreciated.

as you know, disinfectant looks for signatures (i.e. Hpat, nVIR etc.)
and "fuck" is just another signature ...

if you're _very_ concerned about tampering to disinfectant try to arrange
to get a copy from the source listed in the application (i.e. norstad's
home site).

Do not panic.  'fuck' is an nVIR clone that Disinfectant 1.6 catches and
removes.  Because you used SUM Tools to look at the resource fork
instead of a resource editor like ResEdit, you did not see what resource
the string 'fuck' was in.  A 'fuck' resource would mean a 'fuck'
infection, I spotted it in a 'VDEF' resource.  I don't know exactly, but
'VDEF' seems to be where John put information about what resources to
look at to spot a virus infection ('VDEF'<=>Virus DEFinition).  What you
spotted was just the instructions on how to remove the virus.

   I'll betcha a nickel that the obscenity in Disinfectant is something
that the program looks for when it riffles through your resource files.
Very likely some existing virus adds one or more resources of that type,
or by that name.  (The word also holds a strange fascination to the
sort of people who write viruses, so even if it's not part of an
existing virus, it's the sort of thing a suspicious-minded anti-virus
program might want to keep an eye out for.)
   Don't panic.

As others have pointed out, this is a "signature" of one of the nVIR 
clones.  I wondered if anybody would ever discover this, and if they did, 
if they would get worried/upset.  I considered doing some sort of mild 
encryption to "hide" such stuff, but never got around to it.  In any case, 
it's definitely nothing to worry about.

If you look at the sectors either side of that one you will also find the 
following words (amongst others): "MEV#", "nFLU", "Jude", "INIT 29", "MacMag",
and "ANTI" - all ow which are the names of viruses.

I would speculate that "fuck" is the name of a little-known Mac virus. Perhaps
a clone of nVIR B?

I believe that the first thing Disinfectant does is check itself.  If it
notices anything unusual about itself, it won't run.  (Is this right
John?)

Based on this, I think you'd have a tough time running a messed up
version of Disinfectant, so it's probably not worth worrying about.

This is correct. One of the nVir clones (yet another stupid clone) uses
a popular obscenity beginning with the 6th letter of the alphabet as
its resource type. No need to worry about Disinfectant.

Uh, you *do* realize that some versions of nVir say this if MacinTalk is
installed? ;-)

Turns out that yes, such is the name of a variant found at Stanford.  Clever
programmers these virus idiots, eh?  sheesh.
