The recently discovered KRACK security vulnerability affects the majority of devices powered by Android OS that feature Wi-Fi support. Apparently, an attacker within range of an Android device can use the KRACK exploit to read information from that device, which was previously assumed to be safely encrypted.
Unfortunately, that includes sensitive data like credit card numbers, passwords, chat messages, emails, photos and just about anything that’s stored on the device.
Many smartphone companies have already released fixes for this particular security issue, but not Google. Well, it looks like the December security patch will address the KRACK issue, along with other vulnerabilities that would make an Android device less secure. You can find in-depth details about the changes included in the patch at the source link below.
