A Wi-Fi security hack recently discovered leaves countless devices at risk.

The flaw comes when a new user joins a Wi-Fi network. If a signal is sent that an existing encryption key is lost, the same key will be sent again, and could be intercepted by a hacker to allow access to personal information such as passwords and financial information, Time reported. Hackers also can steal personal information that is stored on the computer.

The vulnerability, known as KRACK (Key Reinstallation Attack), can impact any kind of device with Wi-Fi that uses WPA2, which is a common protocol for routers and Wi-Fi devices.

Windows and the latest versions of Apple's macOS and iOS are largely immune to the flaw, but Android users are vulnerable, ZDNet reported. Websites that use HTPPS are encrypted from the browser to the server and also are safe, along with connections through virtual private networks (VPN).

The attacker typically needs to be in close proximity to the vulnerable devices, but with the right equipment, hackers could potentially launch the attack from hundreds of feet, ZDNet reported. Changing your Wi-Fi password will not protect you against the flaw.

Some router and network equipment makers have already created patches to address the security flaw, but major companies Cisco, HPE, and Arris have not yet announced a patch, ZDNet reported.

So far, there are no reports of any attacks, according to The Verge.
