A fake PornHub app installs malware into Android devices. Since Google Play Store does not allow pornographic content into it, the said app can be downloaded from unknown sources which makes the device vulnerable to viruses and malware.
Downloading software from third-party developers is a major security concern for all Android devices. The researchers from cyber security firm ESET found that a new malware disguises itself as a PornHub app. The pushed-to-go third party app will refuse to play a video and will make the user check virus in the device. Since the videos are what users were after, they will follow the instructions. Then, it will install a malware on your phone.
The malware will lock your phone, and will ask $100 in Bitcoin. The PornHub app malware will make the device a "hostage" for the user to pay something back to regain access. But ESET has provided instructions to avoid the infection, and steps to do in order to get rid of the malware if the user already contacted with it.
In order to avoid being infected by such malware, the basic thing is to install apps only within Google Play Store. But if you are too naughty to try installing a porn app like PornHub, you are also risking the possibility of getting infected by the virus.
However, if you are already infected by the malware, you have to undergo several steps to get rid of it. First, you may try rebooting the device into safe mode, to block third party apps and delete the malware. If the lock screen is infected, you may reset the lock screen using Android Device manager. If both were unsuccessful, a factory reset will be the only option - but everything on your device will be automatically deleted. That is the risk of installing apps outside Google Play Store like the PornHub app.
