British Prime Minister Tony Blair and his Web site are the target of a new Internet worm that seems to be low-risk, antivirus software vendor Sophos said.
The worm, dubbed W32/Quaters-A, spreads via e-mail using a variety of subject lines and by Internet chat systems posing as an attempt to break a chain mail world record, Sophos said in a statement on its Web site Thursday.
When activated, the worm overwrites files on the victim's computer with the text "Infected by the WIN32.SORT-IT-OUT-BLAIR Virus!" and can display a message attacking Blair and accusing him of wasting money on immigrants instead of spending it on education or the British heath system, according to Sophos.
The worm also attempts to launch a denial of service attack on www.number-10.gov.uk, the Web site of 10 Downing Street, the prime minister's official residence in London, Sophos said.
The threat of the Quaters worm seems limited. Sophos received only a few reports of the worm infecting computers, the company said.
