US and allied cybersecurity agencies warned that Russian state-sponsored hackers are actively exploiting vulnerable and poorly configured routers in critical infrastructure networks across communications, defence, energy, finance, and healthcare sectors. The advisory calls for stronger authentication, encryption, and network monitoring to counter ongoing FSB-linked cyber operations targeting device configuration data.

◆ The Wire takeaway
