Beware: "LOL" Virus is Roaming Facebook's Chat

Social networks are visited everyday by millions of users worldwide, so it comes as no surprise that these platforms are, nowadays, one of the main targets for hacker attacks. They come in various ways and have different specific targets, making it hard to spot and eliminate this kind of threats.

Recently, a new virus has been detected on Facebook: it has been named "LOL", because affected users received a chat message containing the colloquial expression "LOL. Together with this subliminal message comes an attachment, in the format Photo_xxx.zip or IMG_xxx.zip. The message itself is harmless - the problem comes with the attachment.

Inside that "image", you will not find a typical .jpg or .png file, but a Java file instead. This file will automatically download malware from Dropbox, infecting your system. The origin and content of this malware are still to be identified but, apparently, it comes under several variants.

The "LOL" virus will not only infect your system, as it will also hijack your Facebook account and spread the virus to all your contacts. Due to its novelty, there is not any solution available for the moment, so the best thing to do is paying attention to all the received messages and, if you receive a message fitting this description, do not open it. For people that have downloaded the attachment and executed the file, change the password of your Facebook account and scan your system for threats as fast as possible.

There are a few advices that, even though being old, are useful for this kind of situations. For example, one should never download (and open, obviously) a file that seems suspicious, be it on Facebook, email, and so on. Also, in the specific case of Facebook, pay attention to the sender of the messages you receive and, if you receive attachments from people with whom you rarely speak, be suspicious. Better safe than sorry.
