The Malware: Bedep

Malwarebytes reports that the homepage of xHamster links to traffichaus.com and that an iframe hosted there serves as the gateway to a malicious ad that uses a vulnerability in Adobe Flash Player to download a piece of malware called Bedep. Unfortunately, a lot of anti-virus apps miss the infection in the iframe—according to IBTimes, 57 apps missed the iframe, and only two detected the malware being downloaded.

Once it’s downloaded, Bedep will attempt to download additional malware, and serve up fraudulent ads. The entry for Bedep on VirusRadar states that the trojan is probably part of other pieces of malware, and that it tries to download several files from a URL that’s included in its code.

Other sources say that it can steal confidential information, disable anti-virus programs to prevent detection, add your computer to a botnet, and modify your system settings.

Protecting Yourself from Bedep

Getting Rid of Bedep
