QuadRooter, which is the new malware and about 900 Million devices are affected by it. In response to this vast vulnerability, Google has given some clarifications to source blog.
Google has said that out of 4 vulnerabilities of the QuadRooter Malware. Already, three of them can be prevented from infiltrating using the ‘Verify App’ option in every Android having version 4.2 or above. Here’s what a Google Spokeperson said to Android Central:
“We appreciate Check Point’s research as it helps improve the safety of the broader mobile ecosystem. Android devices with our most recent security patch level are already protected against three of these four vulnerabilities. The fourth vulnerability, CVE-2016-5340, will be addressed in an upcoming Android security bulletin, though Android partners can take action sooner by referencing the public patch Qualcomm has provided. Exploitation of these issues depends on users also downloading and installing a malicious application. Our Verify Apps and SafetyNet protections help identify, block, and remove applications that exploit vulnerabilities like these.“
From this we came to know that Google already had hint about this kind of bug. SO, that’s why they came with this kind of mechanism about few years ago.
