An estimated 80 percent of Android smartphones and tablets running Android 4.4 KitKat and higher are vulnerable to a recently disclosed Linux kernel flaw that allows hackers to terminate connections, spy on unencrypted traffic or inject malware into the parties' communications. Even the latest Android Nougat Preview is considered to be vulnerable. The security flaw was first appeared in the implementation of the TCP protocol in all Linux systems deployed since 2012 (version 3.6 and above of the Linux OS kernel) and the Linux Foundation has already patched the Linux kernel on July 11, 2016. However, the vulnerability ( CVE-2016-5696 ) is now affecting a large portion of the Android ecosystem. According to a blog post published Monday by mobile security firm Lookout, the Linux flaw is present in Android version 4.4 KitKat and all future releases, including the latest developer preview of Android Nougat . Around 1.4 BILLLLLION Android Devices Affected This means that 80%

Linux TCP Flaw allows Hackers to Hijack Internet Traffic and Inject Malware Remotely

If you are using the Internet, there are the possibilities that you are open to attack. The Transmission Control Protocol (TCP) implementation in all Linux systems deployed since 2012 ( version 3.6 and above of the Linux kernel ) poses a serious threat to Internet users, whether or not they use Linux directly. This issue is troubling because Linux is used widely across the Internet, from web servers to Android smartphones, tablets, and smart TVs. Researchers have uncovered a serious Internet flaw, which if exploited, could allow attackers to terminate or inject malware into unencrypted communication between any two vulnerable machines on the Internet. The vulnerability could also be used to forcefully terminate HTTPS encrypted connections and downgrade the privacy of secure connections, as well as also threatens anonymity of Tor users by routing them to certain malicious relays. The flaw actually resides in the design and implementation of the Request for Comments: 5961 ( RF
