All of the modern device with Wi-Fi is vulnerable to hacks because of the Wi-Fi KRACK exploit. Earlier today the researchers revealed the serious exploit in the Wi-Fi networks using WPA or WPA 2 encryption. Now more details about the exploit are available revealing that over 41% of Android phones are affected by multiple vulnerabilities. However, as the problem is in the Wi-Fi standard itself so it affects Windows and other platforms as well.
The researchers have explained that if the breach Wi-Fi Krack is used, it will be able to access all the data sent over the network regardless of what device you use. Data such as the Credit Card details, photos, documents can be sent over the network without your knowledge and the attackers can also inject malicious codes into the devices.
“This can be abused to steal sensitive information such as credit card numbers, passwords, chat messages, emails, photos, and so on,” security researcher Mathy Vanhoef explains. “The attack works against all modern protected Wi-Fi networks,” he added.
He once again confirms that even a TV or fridge could be hacked if it supports Wi-Fi. Apparently, you should not blame Microsoft or any company because the problem is in the Wi-Fi standard itself. “Note that if your device supports Wi-Fi, it is most likely affected,” he writes. While HTTPS connection makes harder for anyone to read the data sent over the network, the exploit has even bypassed it.
On the other hand, particularly Android is most vulnerable to the devasting Wi-Fi exploit. And moreover, it is highly likely that even the OEMs wouldn’t update their Android phones anytime soon. With that being said, it is recommended to update your router, phones as soon as the updates are available.
