A computer worm that propagates by exploiting a 2010 Windows vulnerability is responsible for some of the recent incidents involving network printers suddenly printing useless data, according to security researchers from Symantec.
Many companies have reported unauthorized printing incidents in recent weeks, prompting antivirus firms to investigate the possible causes.
On June 21, Symantec reported that
the rogue printouts were the result of computers being infected with a Trojan program called Trojan.Milicenso.
However, the company's researchers have since determined that the propagation routine of a separate piece of malware, a worm called W32.Printlove, can cause similar problems, Symantec researcher Jeet Morparia said Monday in a
blog post.
