In May, the Justice Department told Americans to reboot their routers. But there’s more to do — and NSA says it’s up to device makers and the public.
LAS VEGAS — The Russian military is inside hundreds of thousands of routers owned by Americans and others around the world, a top U.S. cybersecurity official said on Friday. The presence of Russian malware on the routers, first revealed in May, could enable the Kremlin to steal individuals’ data or enlist their devices in a massive attack intended to disrupt global economic activity or target institutions.
On May 27, Justice Department officials asked Americans to reboot their routers to stop the attack. Afterwards, the world largely forgot about it. That’s a mistake, said Rob Joyce, senior advisor to the director of the National Security Agency and the former White House cybersecurity coordinator.
“The Russian malware is still there,” said Joyce.
On May 8, cybersecurity company Talos observed a spike in mostly Ukrainian victims of a new malware attack. Dubbed VPN Filter, the malware used code similar to the BlackEnergy tool that Russian forces have used (in modified form) to attack Ukrainian infrastructure. The U.S. intelligence community believes the culprits are the hackers known as APT 28 or Fancy Bear, Russian military operatives who were behind information attacks against the Democratic National Committee, State Department, and others. The new malware, if activated, could allow the Russian military to peer into the online activities of hundreds of thousands of people.
“The Cisco-Talos reports on the incident estimated hundreds of thousands of devices affected worldwide,” Joyce said.
Specifically, the May 23 report said, at least 500,000 victims in up to 54 countries.
The malware executes in three stages, according to the Talos report. The first stage is akin to a tick burrowing into a victim’s skin, to “dig in” with its teeth by changing the infected devices’ non-volatile persistent memory, the portion of the memory that persists even after the machine is turned off. During this phase, the malware also establishes links to any servers it finds.
Stages two and three are about receiving and executing the orders. These could include: stealing traffic data from the victim (via port 80), launching “man in the middle” attacks, using the router as a platform to attack other computers as part of a botnet, or overwriting the memory on the router to render it unusable.
The U.S. government effort to stop the attack “was effective at knocking down their command and control. But — and this is a ‘but’ we haven’t seen talked about that much — there was a persistent ‘stage one’ on all of those routers,” said Joyce. “If it was at a stage-two or stage-three implant, it knocked it back to one, which was power- and reboot-persistent. At that point, we couldn’t call back out via those two methods to re-establish command and control,” he told the crowd.
Bottom line: “It’s still on those routers and if you know the wake-up knock you can go in, control those routers, and put a stage two or three back on them… What do you think the odds are that the actors in Russia who put those down have the addresses of the places where the put the malware? I think it’s pretty high,” he said.
