Do you remember? A previous flaw called “Krack” (based on the WPA2 confidentiality agreement) allows hackers to easily steal your private information, and OS, Windows, IOS, Android, and Linux cannot escape this vulnerability.
After Microsoft, Apple, now Google also sent out the Android November update, mainly to repair this based on WPA2 protocol loopholes, and the first to be able to upgrade the taste of their own nexus and Pixel equipment (except for Pixel 2 XL).
Although Google has released the Android update, but manufacturers to follow suit, it is not known, but whenever the release of updates, it is recommended that the first time to upgrade, because it is still very important.
In short, if your device supports WiFi, the vulnerability will affect you, and the attacker would not need to crack the Wi-Fi password to easily steal the user’s credit card number, password, chat information, photos, e-mail, and online communication tool content.
PS: But the current optimism is that the researchers did not disclose the exploit code.
