We'll always have Paris

Believe it or not, that IM you just got from Paris Hilton may not be genuine.

Everyone's favourite celebrity heiress has long been used to lead innocent computer users to various parts of the internet – let's face it, you're only reading this because you typed her name into a search engine – but things have just got worse. Much worse.

According to an engineer from Kaspersky Labs, the Kelvir malware family, which famously made use of footage and images of Paris to entice lonely technophiles, is now more sophisticated than ever, improving its hit rate by, ahem, "separating the worm from the backdoor". A leap in instant-messaging hacking could be just around the corner, he added.

"The worm will only start spreading when the IRC operator (the bot master) gives a specific command in the channel, or to one specific victim machine," said Roel Schouwenberg, senior research engineer at the company. "The worm spreads as a link to the backdoor, not to itself."

More details of the malware can be perused here.

So there you have it: delete any IMs from Paris Hilton on sight. And we wouldn't recommend returning her phone calls, either.
