Two consecutive spam waves of Bagle virus

Only on September 20 and 21, the latest variant of Bagle.DI-U opened two attacks, disabled antivirus software, blocked access to the security website to pave the way for hackers to control the device. charged without obstruction.

Bagle.DI-U spreads through spam containing a blank header, the content is just "new price" and the attachment has the name "09_price.zip," "price_new.zip," and "price2.zip".When users open these files, the virus quickly infiltrates the computer, changes the registry, opens the backdoor and turns off the security program.

Beginning to appear in January 2004, the Bagle worm has expanded at least 70 variants with equal risk levels.

Another round of e-mail viruses, disguised as e-cards from "a person who admires you", has caused a series of computers to be infected in just a few days this week.

The worm called Dloader.UT will immediately download to the computer when the user clicks on the link to the page containing the e-card.The Trojan then controls the entire computer, allowing hackers to install any software on the system to send spam or make other online attack weapons.

The risk behind the e-cards has been pretty much warned recently.The typical example of this trick is the Zafi.D worm, attached to an e-card for Christmas, has dominated the charts of the most dangerous viruses in the past.

UK security firm Sophos recommends that users avoid opening attachments in spam and ensure their antivirus software is up to date."People need to think carefully before clicking on a certain spam. They often make us' think bad 'and then steal personal and financial information," said Carole Theriault, Sophos' security advisor."More and more people writing Trojan programs and spyware use spam to maximize the number of victims."
