US, UK cyber cops warn Russians are rooting around in your routers

After all, it's where all your data is flowing through

American and British crimefighters have launched another round of pin-the-tail-on-the-Russians – with a warning that Moscow-backed hackers are trying to subvert the world's network devices.

The US Department of Homeland Security (DHS), the Federal Bureau of Investigation (FBI), and the United Kingdom’s National Cyber Security Centre (NCSC) on Monday issued a joint Technical Alert describing a global assault on routers, switches, firewalls, and network intrusion detection hardware by Russian state-sponsored cyber actors.

This is not quite the same thing as last month's warning against cyber-attacks on the West's energy utilities and other critical infrastructure, or other cyber threats attributed to Russia-sponsored hacking, referred to collectively as Grizzly Steppe. But it's related.

"FBI has high confidence that Russian state-sponsored cyber actors are using compromised routers to conduct man-in-the-middle attacks to support espionage, extract intellectual property, maintain persistent access to victim networks, and potentially lay a foundation for future offensive operations," the advisory says.

The warning applies specifically to devices utilizing Generic Routing Encapsulation (GRE), Cisco Smart Install (SMI), and Simple Network Management Protocol (SNMP).

Routers give root

US and UK authorities say that since 2015 they've been receiving reports of attacks on routers and the like that aim to advance Russia's national security and economic goals. They contend that the campaign "threatens the safety, security, and economic well-being of the United States."

The advisory says network devices are ideal targets because almost all network traffic passes through them.

"Whoever controls the routing infrastructure of a network essentially controls the data flowing through the network," the advisory says, a possibility that might allow for denial of service, information manipulation or physical destruction in the context of critical infrastructure.

The warning goes on to elaborate on the reasons it's easy to find vulnerable network devices: They tend to get less security attention than servers. Few run security tools. Many are distributed with exploitable services.

Device owners often fail to change default settings, perform security hardening, or commit to regular patching. ISPs often don't replace hardware that's no longer supported by its maker. And network devices often get overlooked during cyber intrusion investigations.

Despite the ebb in relations between the US/UK and Russia – marked by diplomatic expulsions, indictments related to the Internet Research Agency and the 2016 election, the Skripal poisoning, and ongoing events in Syria – the White House appears disinclined to punish Russia for alleged bad behavior.

On Monday, the Washington Post reported that the White House halted Syria-related sanctions against Russia announced a day earlier by U.S. Ambassador to the United Nations Nikki Haley.

And after several years of naming and shaming the Russian government for backing the hacking of US government systems, not much has changed. ®

  • Despite global uncertainty, $500m hit doesn't rattle Nvidia execs
    CEO acknowledges impact of war, pandemic but says fundamentals ‘are really good’

    Nvidia is expecting a $500 million hit to its global datacenter and consumer business in the second quarter due to COVID lockdowns in China and Russia's invasion of Ukraine. Despite those and other macroeconomic concerns, executives are still optimistic about future prospects.

    "The full impact and duration of the war in Ukraine and COVID lockdowns in China is difficult to predict. However, the impact of our technology and our market opportunities remain unchanged," said Jensen Huang, Nvidia's CEO and co-founder, during the company's first-quarter earnings call.

    Those two statements might sound a little contradictory, including to some investors, particularly following the stock selloff yesterday after concerns over Russia and China prompted Nvidia to issue lower-than-expected guidance for second-quarter revenue.

  • Another AI supercomputer from HPE: Champollion lands in France
    That's the second in a week following similar system in Munich also aimed at researchers

    HPE is lifting the lid on a new AI supercomputer – the second this week – aimed at building and training larger machine learning models to underpin research.

    Based at HPE's Center of Excellence in Grenoble, France, the new supercomputer is to be named Champollion after the French scholar who made advances in deciphering Egyptian hieroglyphs in the 19th century. It was built in partnership with Nvidia using AMD-based Apollo computer nodes fitted with Nvidia's A100 GPUs.

    Champollion brings together HPC and purpose-built AI technologies to train machine learning models at scale and unlock results faster, HPE said. HPE already provides HPC and AI resources from its Grenoble facilities for customers, and the broader research community to access, and said it plans to provide access to Champollion for scientists and engineers globally to accelerate testing of their AI models and research.
