There’s a new malware threat spreading fast on the Internet, and this time it’s targeting Facebook users.

If you get this suspicious link via Messenger from one of your Facebook friends, don’t click on it!

This malware, which replicates over Facebook’s internal messaging system, Messenger, is circulating and spreading heavily. This is a form of social engineering used to trick people and steal sensitive data.

Here’s how it works

The message includes a BIT.LY link (Bit.ly is a URL shortening service) which contains a video with the person’s name. Once the user clicks on the malicious link, it redirects the entire traffic through a big chain of malicious domains.

Un-shortening the URL leads to (sanitized for your protection):

Here is a selection of the malicious URLs involved in delivering and keeping the distribution covert (sanitized for your online safety):

Http: // bitly [.] Com / 2v8tlRs? [Name of recipient] https://docs.google [.] Com / file / d / [unique ID] / preview
http: // dilosi [.] Bid / ad / 1010442020
q.redirecting [.] Website
FlashPlayerPro_0851280053.exe

The final destination is a domain where the malware, in this case adware, is downloaded from.

This strain of adware tracks cookies, monitors your online activity, and shows different ads that lead to potentially malicious URLs.

Researchers have discovered that this campaign uses various attack angles, such as a browser extension for Chrome and Firefox, or a binary package that installs adware on users’ computers. The binary package is offered to Safari and Microsoft Edge / Internet Explorer users.

According to SecureList, when using the Firefox browser, it sends users to a website displaying a fake Flash Update notice, and then showing a Windows executable.

The browser extension for Chrome is a downloader, which will download a file to your personal computer.

Here how it looks:

The adware is installed via (sanitized for your online safety) this website: www.currentcleannew.com and is named as a “VideoPlayer”, which looks like a playable movie that users are tempted to access.

Here is an installation package that will be installed as default to the
