Copycat Virus Unleashed
As if the hangover from "My Party" wasn't enough to deal with, malicious copycat pranksters unleashed a new virus this week dubbed "W32.Porma@mm". The mass-mailing email worm is distributed via email with the subject line, "pornoman recommends". The Body of the message reads, "visit the site.. sex, sex, sex and more sex". The attached file, http.www.sex.com looks like a web address.
The clever part about this strain of virus is that the attachment is deceiving. It appears as a link to a web site address, but it isn't. The ".com" part of the address actually signifies that the file is a program. If you click on the .com file, you execute the program.
When the program is run, the W32.Porma@mm worm sends itself to all contacts in the Microsoft Outlook address book. It also copies itself to C:\http.www.sex.com.
Users should remain on the look-out for this new style of email worm. According to Donal Casey, of security firm Activis, this new style of worm represents " a new direction for virus authors as they are utilising the fact that web addresses can end in .com, also the extension DOS executable command files."
"As this is a new direction for viruses, I would expect to see a rash of viruses using this technique in the short term until users become educated and do not randomly click on web links delivered through email."
