Beware Of Virus-Riddled Y2K E-Mail
(09/15/99, 3:36 p.m. ET)
By Lee Kimber, Special To TechWeb, TechWeb
Antivirus experts are urging computer users
not to open a year 2000 countdown program
that comes in the form of an e-mail sent by
Microsoft on Tuesday.
The e-mail was not sent by Microsoft, and the
enclosed attachment is not a Y2K countdown
program, but rather a Trojan virus. If users attempt to
open the alleged program, the virus can install itself
onto the user's computer and then is capable of
sending data and information from that system
across the Internet.
Microsoft did not return calls by publishing deadline
time.
Antivirus experts at Star Internet, a U.K.-based ISP,
along with Network Associates and Sophos, are
analyzing the e-mail attachment, called
"Y2Kcount.exe." Star has confirmed that the virus,
which has been named Count2K, originated in
Bulgaria and has also identified some key warning
signs.
"It makes a lot of socket communications calls," said
Star antivirusprogrammer Alex Shipp. "There's also a
lot of file handle calls and keyboard handling calls."
Shipp said similar to the ExploreZip virus that
decimated corporate e-mail systems several months
ago, Count2K appears to have the ability to take files
from users' systems and send them across the Net.
The destination of the files or data has not yet been
determined by Star's virus experts. On Wednesday,
Network Associates antivirus experts confirmed
Shipp's findings.
Shipp's analysis has determined -- that like the
ExploreZip Trojan virus -- both are written in Pascal.
He also said the internal programming of two viruses
are very similar.
Users who simply open the e-mail but do not attempt
to load the Y2K program are in no danger from the
virus. Users who try to install the program will see a
message saying the Y2K counter was unable to
install. It says: "Error!..Password protection error or
invalid CRC32!."
However, analysis of the program's installation
routine shows it already has connected to internal
Windows files by the time it displays the error
message, Shipp said.
"If you see that [message], you think it failed," said
Shipp. "By then, it has installed itself."
The message first raised eyebrows because of
awkward wording that didn't seem like it would come
from Microsoft. The accompanying message headers
also suggested that the e-mail passed through
CompuServe's e-mail system. No valid e-mail from
Microsoft should route through CompuServe.
Antivirus experts said they are working quickly to
develop a Count2K fix. Network Associates
confirmed that programmers in their antivirus labs
are working on a patch. Sophos has posted a
warning on its website alerting users that it is working
on a patch. Star Internet has already protected its
1,000 U.K. business customers from the Trojan by
installing a scanner on its e-mail servers. The
scanner looks for the Trojan's unique signature.
