We have recently seen cybercriminals taking advantage of the previously reported “Android installer hijacking” vulnerability, which affects Android versions 4.3 and older, or roughly half of Android devices, to download malware into user systems. The Android hijacking bug can reportedly shortchange users who download apps from third party app stores into actually downloading malware and give these permissions without their knowledge.
If you have been following network security news closely, you would have also heard of how researchers released a scanner app for Android users to check if this vulnerability affects them. The fear of being vulnerable to this threat has given cybercriminals a way to install malware on user devices.
We found the following sites that show up when users search for the keyword “scanners” for the said flaw:

This recent social engineering tactic can be considered a test of the readiness of Internet users to anticipate threats, even those who are driven to be mindful of their digital security. Cybercriminals can be quite creative when it comes to creating lures, always taking advantage of topics that strike human interest.
These recent events were also abused to lure users into sharing personal information or downloading threats:
Always be mindful of what you click on when you're online. Cybercriminals will always try to get into your system by leveraging your online activities—which include web surfing, social networking, online shopping, checking emails, online banking, and more.

Be wary of downloading apps from third party sources and always stay updated on the recent threats to mobile safety. Protect both desktop and mobile devices with security solutions that block threats in real time without hampering device performance.
