Two New Computer Worms Detected

Two new computer worms detected

LOS ANGELES, Jan. 25 (Xinhua) — Los Angeles-based Panda Security announced on Friday that it has detected two new computerworms, Nuwar.OL and Valentin.E, that use the topic of Valentine’s Day to spread.

“Year after year, we see the appearance of several malware strains that use Valentine’s Day as bait to attract users,” said Luis Corrons, technical director of PandaLabs. “This indicates that cyber-crooks are still reaping the benefits of this technique,and many people still fall into the trap.”

Nuwar.OL reaches computers by e-mail with subjects like “I LoveYou So Much,”"Inside My Heart” or “You … In My Dreams.”

The text of the e-mail includes a link to a Web site that downloads the malicious code.

The page is very simple and looks like a romantic greeting card,with a large pink heart. Once it has infected a computer, the wormspreads by sending e-mails to the infected user’s contacts, which also creates a heavy load on networks and slows down the computer,according to PandaLabs.

Like the Nuwar worm, Valentin.E spreads by e-mail in messages with subjects like “Searching for True Love” or “True Love” and anattached file called “friends4u.”

If the targeted user opens the attached file, a copy of the worm will be downloaded. The malicious code installs on the computer as a file with the .scr extension. If the user runs it, Valentin.E shows a new desktop background to trick the user, whileit makes several copies of itself on the computer. Finally, the worm sends out e- mails with copies of itself from the infected computer to spread and infect more users.

“Both cases are clear examples of social engineering techniquesused to spread malware. They use attractive subjects — Valentine’s Day greeting cards, romantic desktop themes, etc. — to entice users to run attachments or click links that ultimately download malware onto their computers,” Corrons said.

To avoid becoming a victim to computer viruses, Panda Security offered the following tips:

— Do not open any e-mails that come from unknown sources.

— Do not click on links in e-mail messages, even if they come from reliable sources. It is better to type them in the address bar.

— Do not open attached files that come from unknown sources. Be wary of files that claim to be Valentine’s greeting cards, romantic videos, etc.

— Protect your computer with security software capable of detecting both known and new malware strains.
