Spurious commands are sent to printers making them print rubbish

Thousands of office printers around the world have been hit by a Trojan that has caused them to churn out pages of gobbledegook.

The malicious software, Milicenso, was first discovered by security firm Symantec two years ago. Its main aim is to hide itself from security software in an attempt to carry out attacks. The problem affecting printers appears to be an unintended consequence of this action.

Milicenso enters victims' PCs through infected email attachments or rogue links. It then downloads software that sends commands to printers instructing them to output massive numbers of pages.

More information can be found on Symantec's blog.
