Researchers have found a huge flaw in the security used to protect Wi-Fi networks that could potentially allow hackers to steal credit card details, private messages, photos, and more.
The weakness was found in the security protocol WPA2 and is being referred to as a “key reinstallation attack” — or KRACK, for short.
But don’t worry, it only affects devices that support Wi-Fi. Uhhh, wait…
And now for the good news
Vendors were first warned about this issue back in July, so companies had time to prepare patches before the attack was publicised.
Then there’s the fact that, in order to exploit the vulnerability, the attacker needs to be on your Wi-Fi network. So, unless your Craigslist roommate is a hacker, you have a low chance of being targeted at the moment.
And lastly, other levels of encryption have not been compromised, including the HTTPS tech used by most banks and financial institutions online.
What can I do to protect myself?
According to TechCrunch, there are a few ways to decrease your chances of falling victim to a KRACK attack:
- Update every wireless item you own.
- Update your router’s firmware
- Consider using your cellular data
- Install the HTTPS everywhere extension
They also suggested moving to the woods. So, at least paranoia isn’t setting in.
