Using data provided by BinaryEdge, our scans have found 25,617 Linksys Smart Wi-Fi routers are currently leaking sensitive information to the public internet, including:
- MAC address of every device that’s ever connected to it (full historical record, not just active devices)
- Device name (such as “TROY-PC” or “Mat’s MacBook Pro”)
- Operating system (such as “Windows 7” or “Android”)
In some cases additional metadata is logged such as device type, manufacturer, model number, and description – as seen in the example below.
Other sensitive information about the router such as the WAN settings, firewall status, firmware update settings, and DDNS settings are also leaked publicly.
