There is an epidemic of the Sober worms being found, according to security outfit Kapersky Lab The company has spotted three new versions of the Sober worm which it has labeled Sober.u, Sober.v, and Sober.w.

Large numbers of emails infected with the worm have been distributed by spammers and in recent months it has been delivering far right propaganda.

The attachments are called Exceltab-packed_List.exe, Liste.zip and Reg-List-Dat_Packer2.exe., reg_text.zip Word-Text.zip, Word-Text_packedList.exe and Word-Text_packedList.zip.

It is a bit odd that Sober, which disables anti-virus software, still catches people out. It has been in the wild since 2003 and requires people to click on an attachment to work.

Once launched, the worm causes a false error message, “WinZip Self-Extractor. WinZip_Data_Module is missing ~Error”, to be displayed on screen.
