Malware targets Facebook users on Google Chrome, Mozilla Firefox

Mumbai: Facebook users, especially those accessing the service on Chrome and Firefox browsers, here's something that you ought to take note of.

On its Technet blog, Microsoft has revealed that it has received reports about a wave of malware-ridden browser extensions attempting to hijack Facebook profiles. This threat, which they have detected as Trojan:JS/Febipos.A., was first discovered in Brazil. It has been found to be specifically targeting Chrome and Mozilla Firefox.

Detailing on the nature of the malware, Microsoft says that upon installation, the malware tries to update itself using URLs like -

Chrome browser - du-pont.info/updates//BL-chromebrasil.crx

Mozilla Firefox browser - du-pont.info/updates//BL-mozillabrasil.xpi

Importantly, updated versions of this malware have been verified too, and have been detected as Trojan:JS/Febipos.A.

At the outset, the Trojan sees if a user is logged in to Facebook at the time. It then tries to get a configuration file from the website - .info/sqlvarbr.php. This configuration file comprises a host of commands of what the browser extension will do.

Worryingly, depending on the file, here's what the malware can do any of the following in the Facebook profile of an infected system:

- Like a page

- Share

- Post

- Join a group

- Invite friends to a group

- Chat to friends

- Comment on a post

The post adds that the configurating file was also found to contain a command to post the following message in Facebook -
