Microsoft warns of new Trojan hijacking Facebook accounts

Microsoft has issued a warning that a new piece of malware masquerading as a Google Chrome extension and Firefox add-on is making the rounds, threatening to hijack Facebook accounts

First detected in Brazil, Trojan:JS/Febipos.A, the malware attempts to keep itself update, just like normal, legitimate browser extensions, Microsoft noted in a security bulletin late Friday.

Once downloaded, the Trojan monitors whether the infected computer is logged into a Facebook account and attempts to download a config file that will includes a list of commands for the browser extension. The malware can then perform a variety of Facebook actions, including liking a page, sharing, posting, joining a group, and chatting with the account holder's friends.
