SWEN Sure Cure

Only sure way to stop SWEN dead cold is to change your E-mail address,
then be sure it's munged to the newsgroups.

A bit of trouble sure, but what a relief.

That's not stopping it, it's running away from it. Maybe the simplest
solution for YOU, but does nothing to stop the shit.

The only way to stop Swen is to report the infected computers.

I started reporting each Swen email two weeks ago, when I was getting
75 - 100 / day. This was a fscking nuisance, but I have gotten none
for the past few days. You need to report each infection as soon as
you can; each email you're getting is also going to somebody else who
may become infected and make the problem worse.

There is one and only one valid way to identify the ISP for the
infected computer, which requires that you examine the headers. Here
is an example:

Send this complaint, with full headers, to abuse@tiscali.it.

There are any number of online whois lookup tools. I use All-NetTools
( http://www.all-nettools.com/tools1.htm ) and Broadband Reports (
http://www.dslreports.com/whois ).

Also, there are several tools which you can install. I use Sam Spade
( http://www.samspade.org/ssw/ ) and TESP ABouncer (

and both help you format and send the complaint.

Man, you've got to be kidding, right?!...

You'll never get enough people to take that much trouble.

I believe SWEN is here to stay, until most ISPs institute a program of
scanning everything and deleting (undelivered) positives for SWEN.

That's pretty ambitious, as during its peak I was receiving a copy of
Swen approximately every 10 seconds. I think I stopped counting once I
reached around 25,000 copies of it.

If I were to reply to each one, I'd be a full-time 24/7 job for me.

What I did on the fist day of mailboxes filling up; I just adjusted my spam
filters at the server level to drop it. Haven't had a SWEN mail find
it way past since.

It's a pain in the @ss, admittedly.

But it's NOT here to stay. People are becoming aware of it, and
cleaning their computers. Some folks read about it, and clean
themselves before they get a notice from their ISP. Others are
getting notices from their ISP, after somebody like me sends the ISP a
report - THEN cleaning themselves.

Some ISPs are filtering it too. Other ISPs are warning their
customers - then taking them offline til they clean themselves.

My incoming Swen has stopped anyway. Reporting it worked for me.

If everybody would report it, it would go away quickly. If a few of
us report it, it will go away slowly, and eventually it will get to
the point where the rest of us start to see a reduction. Then they'll
be able to report it too.

You don't have to report all of what you get. Just take some spare
time and report some - that lessens the load on everybody. I waited
about a week after I first started seeing it, til I had some spare
time. Then I took the most recent emails, and reported them. After a
couple days of doing that, I started to see less. Then I was able to
take the older ones and report them.

Use a tool like TESP, you can analyse, create report, and dispatch in
15 seconds. Faster if you have good eyesight and reflexes (mine are
starting to go - too much late night parties . A fast computer
helps too.

Even someone like JM will see a reduction eventually.

I started using a 3rd party email service (www.me2u2me.com) which has
free email spam and virus protection I managed to get my incoming
email SWEN reduced from 200 a day to 10 a day. But now it suddenly
creeped back to 40 a day so therefore I don't believe fighting each
and every sender is an total solution.

I am using a ISP called 3web and all the users of 3web are getting
this email. I reported the problem to them but they replied back
saying they are doing everything they can to resolve the problem.

The ONLY way this is going to stop is when most ISPs start scanning
all E-mail for SWEN and deleting anything that tests positive.

Meanwhile, some logical change to your E-mail address will stop it
cold.

Granted you wont be receiving them for a while, but probably only for a
short while. You'll be giving out your new address, and most likely to the
same infected person that affected you. If they haven't learned their
lesson....., if they're still infected....
BTW, if casagiannoni3-AT-earthlink.net is an address back to you, you might
want to know it appears in your X-Trace headers. Apparently this is new for
Earthlink.

Apparently SWEN doesm't harvest from this part of the headers since I
haven't gotten any yet.

If you munge your address, the newly infected computers will find
other addresses from Usenet, and you'll be ignored.

I was getting almost one a minute about a month ago. I started writing to
the ISPs, munged my address and I am down to 70-80 per day. Many ISPs will
contacted the suspected user - Earthlink suspends the account until the
computer is cleaned of the virus. However, Swen is here to stay because 1)
of irresponsible ISPs (which I would like to be identified in this
newgroup), 2) idiots who do not use virus protection software and have an
unnatural compulsion to open attachments from people they do not know.

But, on a good day I get a small number of responses
"found that, fixed it, thanks"
And out of the 233 hosts that have sent SWEN since last Wednesday,
168 of them sent less than 3. Perhaps that means that most of
those hosts tracked down their infected customer and put a stop
to it. Otherwise I'd guess they would have sent a dozen or more
to me like many of the rest of the hosts did.

The voice of "Don Taylor" drifted in on the cyber-winds,
from the sea of virtual chaos...


It's sad fact that you lead a horse to water but you can't make him
drink...

Current Telus actions to combat viruses:
- Free antivirus software
- Weekly virus alerts & updates via their newsletter
- A stricter TOS, with auto suspension (for 2 years now)

And despite all this there is still enough morons using Telus to keep
it in the bad graces with some of the more zealous anti-spam crowd.

To this end I've since turn off "auto purge" on my bit bin account, and
have reactivated a few alias of mine that I know Swen has, in hopes of
getting these local violators Tossed. After all, once I set-up my
servers I'd like to meet a favorable crowd, rather then get black-holed
just because I have a Telus IP...
