You mean that if that were included in the source to a
large program (ELM, for instance) you'd notice it was there
before compiling it? I doubt I would.
Regards,
Cliff.
Yes, I think would have a good chance of noticing such a thing
(even if for no other reason that I have to tinker around with
every programm for a few hours before it compiles anyway :-).
Secondly and possibly more importantly: Someone would notice, and
fast. I dare say that if some source is available via anonymous
ftp and is not completely unpopular, no virus would go undetected
for more than one or two weeks, at most. And when it is detected
the sources WILL be removed, there will be an outcry and emergency
broadcasts on all usenet-channels (:-), and the author (or whoever
put the sources there) will be in deep trouble.
A virus in binary form , on the other hand, is hard to spot or
to trace (if it is intelligently done, of course). It may take
months before someone notices effects, and after that it can
take many more months before someone can trace this virus back
to this particular piece of software.
