More Information
W32/Mimail-T is an email worm.
W32/Mimail-T copies itself to the Windows folder with the filename kaspersky.exe and sets the following registry entry so as to run itself on system startup:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\KasperskyAv
W32/Mimail-T harvests email addresses from the host computer, storing them in a file called outlook.cfg in the Windows folder. W32/Mimail-T also takes a checksum of the addresses and stores the checksums in a file called crc32.cfg in the Windows folder. The worm then attempts to send itself to the harvested addresses using its own internel SMTP engine.
W32/Mimail-T attempts to gather password information as the host accesses certain PayPal related websites. W32/Mimail-T stores the gathered information temporarily in the files C:\tempeg2.txt and then base-64 encoded in C:\tmpgld.txt, before emailing it to a number of addresses using its own internal SMTP engine.
W32/Mimail-T attempts to launch a Distributed Denial-of-Service attack against a number of websites related to webhosting and spam prevention.
W32/Mimail-T deletes the file zipzip.tmp in the Windows folder.
W32/Mimail-T contains the following text:
"*** GLOBAL WARNING: if any free email company or hosting company will close/filter my email/site accounts, it will be DDoS'ed in next version. WARNING: centrum.cz will be DDoS'ed in next versions, coz they have closed my mimail-email account. Who next? ***"
