OpenWrt fingerprint scan finds over 2.3 million routers, highlighting remote work security gaps.

A recent scan using the ZoomEye search engine identified over 2.3 million internet-connected devices running the OpenWrt firmware as of late September 2026. This open-source software is commonly used on consumer and home office routers, which have become critical network edges in remote work environments. These devices often have remote management enabled and are updated infrequently by their owners, creating potential security vulnerabilities. Security recommendations include treating home networks as untrusted and using managed tunnels and device checks for corporate access.
