Re: Anyone else notice that Swen is slowing down?
Well, to respond to the subject first: No, Swen is definately not
slowing down here... And my attempt to install amavis/clamav was a bit
of a failure, so I'm seeing a lot of crap...

Well, a virus like Swen wouldn't need root access to spread. I don't
know what Swen does to a Windows machine (and I don't care, I haven't
got any), but just to annoy people with enormous amounts of e-mail,
someone could imageinebly write a perl script with its own SMTP-engine.
If a non-priviliged user was fooled into executing the perl script, it
could still spread to any platform with Perl installed.
Indeed, it is unlikely that such a virus would make any significant
impact on the system, unless of course, it was then able to exploit a
local vulnerability to gain root (or gid 'games', I love those
upgrades! :-) ). However, most users have their most important
documents in their home dir anyway, so a virus deleting those would do
real damage anyway, and it would do real damage to Linux' reputation as
being more secure.
Scenario: A perl script deleting all the files in the homedir of
infected users, spreading to all the contacts that is in user's
addressbooks. This would likely include all the homedirs of all the
users in an organization:
PHB: Sysadmin, what's happening?
Sysadmin: A simple virus. It didn't damage the system, we're running as
PHB: What do you mean, didn't damage the system, it deleted all my
The PHB is not going to care a lot for the integrity of the system once
his files are all gone, his perception of damage is going to be very
different from yours.

I agree, and this is the major point that we have to ensure as MS
marketshare starts dropping and we start taking over the desktop, Linux
users are more clued. A company starting migration to Linux must
realize that for their own security, they have to train their employees
better than they did with MS systems.
Anyway, I think the main technical strength lies in that a lot of
seemingly unimportant fixes are given attention, so that there will not
exist many possibilities to execute code unless the user knows about
