NetworkWorld is reporting that a new variant of the Dorkbot malware was discovered spreading through Facebook's internal chat service, in an attempt by cybercriminals to harvest users' passwords.

Bitdefender researchers discovered links to the malware circulating among Facebook users in the United States, India, Portugal, the United Kingdom, Germany, Turkey and Romania. The security firm did not know the extent of the infection on Monday, but said it counted 9,000 malicious links to the malware in 24 hours.

Bitdefender notified Facebook, which cleared the site of the infection on Tuesday.

"They' were very prompt in their response and they probably protected a lot of users," Bogdan Botezatu, senior e-threat analyst for Bitdefender said.
