Destructive new worm appeared

Exactly two weeks after the attack of the ILOVEYOU worm, a new variant of the virus has crippled several networks. The experts warn of a VB script that is a mail with the subject line beginning with “FW:” is sent.

The new variant is spreading more slowly than the original Lovebug virus, but depends much more damage to the infected computer: “A significant percentage of these computers is no longer usable,” said Vincent Weafer Manager Symantec. The virus puts all files in all folders of an affected computer to 0 bytes.

The tricky at the new worm: He looks out on the harddisk of an infected computer and sends itself a file name as a script with this name. For example, the virus finds a file named “Rechnung.doc” so planted it may be continued at all in the Outlook address book on the infected computer’s stored e-mail addresses as an attachment named “Rechnung.doc.vbs”. In the subject line only after the “FW” only the name of the document is given, but without the “. Vbs” extension.

The latest worm has, according to the experts also called “polymorphic” abilities. In any reproduction, he changed his own code a few variables, so it is difficult to fight for anti-virus software.

The experts recommend three to computers to protect them from the worm:

Network administrators should block all emails with. “Vbs” attachments.Outlook users should regularly download patches from the Microsoft site.Windows 98 users should disable the Windows Scripting Host.

As the first company Trend Micro has responded to the virus and for the users of the anti-virus software detected a patch available.

ZDNet reported in a constantly updated news to report ‘ILOVEYOU’ on the further development and is in addition to basic knowledge and links to antivirus vendors.
