Technologist, Office of Technology Research and InvestigationIf you have a smartphone, laptop, or IoT device connected to a Wi-Fi network, the information you send over that network could be at risk. Researchers recently found a bug that lets attackers break the encryption that protects most wireless networks – leaving data you send exposed.
The bad news is that this is not a problem with a specific device, or even manufacturer – it’s a problem with the WPA2 encryption standard nearly all Wi-Fi devices on the market today use to scramble communications, preventing eavesdropping and tampering. Basically, if you use a device to connect to a wireless network at home, work, or elsewhere, this bug means you cannot rely on that connection being secure.
The good news is that the bug can be fixed with a security update or patch. Device manufacturers and software companies are aware of the bug and updates for affected devices should be rolling out in the near future, if they haven’t already.
In the meantime, connections other than Wi-Fi (like your smartphone’s 4G/3G carrier connection, or a connection with an Ethernet cable) are not affected. So, consider using them instead of Wi-Fi until the updates are available.
