The U.S. government will try to wrestle hundreds of thousands of infected routers from control of hackers who apparently were planning to attack Ukraine. Cisco Systems and Symantec warn that a half-million internet-connected routers have been compromised, the Associated Press reports. “FBI has seized a key website communicating with the massive army of hijacked devices, disrupting what could have been — and might still be — an ambitious cyber attack by the Russian government-aligned hacking group widely known as Fancy Bear,” reports Raphael Satter, AP’s European technology reporter. “Cisco said the malicious software, which it and Symantec both dubbed VPNFilter after a folder it creates, was sitting on more than 500,000 routers in 54 countries but mostly in Ukraine, and had the capacity to render them unusable — a massively disruptive move if carried out at such a scale.”
