More than 1,000 people have been tricked into installing a Trojan after clicking on a new Facebook scam that promises naked videos of their friends. According to Bitdefender Labs, the countries with the most detected infections are Romania, the UK, Italy, France and Germany.
The scam has just started to make rounds on the social network and can multiply itself and tag users’ friends extremely quickly. Over 6,000 .tk websites have been registered for malicious purposes. To avoid detection, cyber-criminals vary the scam messages from “user’s name private video” to “user’s name naked video” or “XXX private video”. Malware writers can also redirect users to fake surveys or toolbar, video and converter downloads.
When clicking the link that promises videos of their friends naked, users are redirected to a fake YouTube website where a “FlashPlayer.exe” file deploys a Trojan. The malware installs a browser extension capable of posting the scam on users’ behalf and stealing their Facebook pictures.
“Adobe Flash Player has crashed, please update to the latest version,” the fraudulent web page reads.
To increase the infection rate, the malware has multiple installation possibilities. Besides the automated and quick drop on the computer or mobile device, it also multiplies itself when users click the fake Adobe Flash Player update.
To make the scam more credible, cyber-criminals faked the number of views of the adult video. Over 2 million users have allegedly clicked on the infected “YouTube” link. To add another touch of realism, the malware creators also added a message that the video is “age-restricted” based “Community Guidelines”.
Scammers also fake the date they uploaded the malicious video by making it current. Bogus Flash Player installers have been infecting users on Facebook and Twitter for a couple of years.
The malware is detected by antivirus software provider Bitdefender as Trojan.FakeFlash.A (Trojan.GenericKD.1571215), while the fake YouTube link is marked as a fraudulent attempt. For maximum protection, the Bitdefender free application Safego also alerts users about the naked video scam circulating on the social network.
