- Panda Software warns users of the new Mimail.I worm -

Madrid, November 14, 2003 - PandaLabs has detected a new variant, of the
Mimail worm (W32/Mimail.I.worm). This variant, like its predecessors, is
designed to spread rapidly in e-mail messages that use so-called social
engineering techniques to trick users and infect their computers. In this
particular case, the message refers to the PAYPAL payment system.
Mimail.I arrives in an e-mail with the subject: YOUR PAYPAL.COM ACCOUNT
EXPIRES, while the message text tells users that they should update their
PAYPAL account as it is about to expire. Full details of the text are
available at Panda Software's Virus Encyclopedia, at
http://www.pandasoftware.com/virus_info/encyclopedia/.
The attachment that accompanies the message is called either w w
w.paypal.com.scr or paypal.asp.scr. If the user runs the file, Mimail.I
searches the computer for e-mail addresses in all files on the computer with
extensions other than: COM, WAV, CAB, PDF, RAR, ZIP, TIF, PSD, OCX, VXD,
MP3, MPG, AVI, DLL, EXE, GIF, JPG and BMP. These addresses are stored in a
file called el388.tmp. The worm then uses its own SMTP engine to send itself
to these addresses, without the user being aware of what's happening.
Mimail.I generates other files (EE98AF.TMP and SVCHOST32.EXE) in the
computer, which are really copies of the worm itself.
Finally, creates a Windows registry entry in order to ensure it is run every
time the system is started up.
Mimail.I is the latest in a string of variants that have appeared over the
last few weeks. It would therefore seem that the author or authors of these
viruses want to spread as many worms as possible in order to increase the
probability of a computer being hit by a variant of Mimail.
Due to the possibility of being infected by this variant, Panda Software
advises users to treat all e-mails received with caution, and to update
their antivirus solutions if they haven't already done so. The company has
already made the updates to its products available to users to ensure their
solutions can detect and eliminate Mimail.I. Similarly, users can also
detect and disinfect this and other malicious code using the free, online
antivirus, Panda ActiveScan, which is available on the company's website at
