Is this email a virus?

T

Top Spin

About once a week or so, I get an email message addressed to me with:

From: Mail Delivery Subsystem [[email protected]]

Subject: Returned mail: User unknown

The body of the email is copied below. There are always 2 attachments
with names like:

ATT00013.DAT & ATT00016.TXT

This looks like I tried to send an email to (e-mail address removed), but I
have no such email address anywhere in my contact list and I do not
recognize the address.

Can anyone tell me wat this is?

Thanks

The files; ATT00013.DAT & ATT00016.TXT are not indicative of email infectors. They are
most likely generated by two different email systems trying to communicate. Extensions such
as; BAT, PIF, COM or using double extensions are signs of infectors in email.

If you were to examine the two attachments they most likey contain the orginal email message
and/or headers.

Now it is possible that your email address was found on a friend's PC who was indeed
infected and the infector sent out email using your email address. Then the failed email
came back to you by assuming you had sent the email. So it is likely the failed mail
message is the result of a an emailed virus, but what you received is not neccessarily a
virus.

If you want to be sure, sbmit both ATT00013.DAT & ATT00016.TXT to Virus Total --
http://www.virustotal.com/flash/index_en.html
The submissions will then be tested against several different AV vendor's scanners.

Another way to submit is to send the suspect file to the following email address
scan<at>virustotal.com
{ replace <at> with @ } with only the word SCAN as the subject.

Please post back the EXACT results.

OK. I forwarded the email with both attachments. The text of the reply
is below. It appears that it only scanned one of the files.

It looks like it's OK to examine the contents. Right?

I always thought that files with .dat and .txt extensions are safe to
open with WordPad or similar. Is that incorrect?

Thanks

Well, I didn't mean to "forward" the email to Virus Total, just submit the two ATT*.* files
for confirmation. ;-)

Yes, you can open .DAT and TXT files in WordPad.

An odd thing happened when I went to that site. The CPU usage
immediately jumped from 2-3% to 85%. I can go a number of other sites
and the CPU usage drops back down to single digits, but it I return to
VirusTotal, it jumps back to 85% and stays there.

What is that site doing?

It looked like I had two options: (1) I could "submit" the files,
which I thought meant that I would need to save them on my disk first,
or (2) send the files as an email attachment per the instructions on
the bottom half of the page.

The forwarding worked, but it only scanned 1 file.

I saved them both and then submitted them using the web site. Both
came back clean.

OK, I did. The contents of each are below. I removed my email address
in the second one.

Is it possible that some spyware is sending messages from my machine?

I downloaded AdAware, but stopped running it because it never found
anything. I do have the corporate edition of Norton Antivirus running
and a hardware firewall on my DSL connection. Both are instaled and
maintained by the leasing company where I get my computer systems.

Thanks

I thought maybe the virus writers had made it look like it came from
AOL so I would open the attachment and catch the virus. But this looks
like it is a real bounced email message from AOL. Right?

Is there any way to tell where the email that got bounced was sent
from? If it was from my machine, then I need to disinfect it. If from
someone I know, I would like to tell them so they can disinfect
theirs.

Thanks

I'm not that good at knowing the real source of email but my guess would be...

Look at the full header (or as much as AOL sent you back)
If it was from my machine, then I need to disinfect it. If from
someone I know, I would like to tell them so they can disinfect
theirs.

odds-on it was from some spammer who faked you as the 'from' domain. AOL
is not very canny about what it bounces or where it bounces it to. I get
them all the time.

Are you a Packard Bell customer? If not, follow the advice given in the
WHOIS info eg from
http://ww1.arin.net/whois/
re the IP number 64.175.164.2
"please send all abuse issue e-mails to (e-mail address removed)"

which means, send this file AT00016.TXT to said address, and tell them
you got a "bounce" because someone faked your address.

I don't think those two MS KB articles are relevant as the contents of the DAT and TXT files
don't jive with the information in the KB articles.
