Facebook user accounts hacked by Ramnit worm

Facebook users, especially those in the United Kingdom and France, have been hit by the Ramnit worm recently. It’s estimated that more than 800,000 machines were infected with Ramnit since September 2011, though not all had been hit by the Facebook attack.

A worm is a self-replicating program that multiplies without needing to attach itself to an existing program or without the user's intervention. This ability means worms can spread very rapidly online. Reports say the Ramnit worm is being used to steal names and passwords from accounts. Facebookers who use the same log in and password for multiple accounts risk having information stolen from them which cybercriminals trade through online black markets.

avast! Antivirus products protect you against Ramnit and other malware, but if you are guilty of using the same log in and password for all your online services, then you could use Avast passwords free password manager. Avast passwords generates strong, unique passwords for every site you visit – with just one click. The best part is that you access your passwords using one Master Password, so you don’t have to remember lots of passwords.
