The US Says It Has Inserted Offensive Malware Into Russia’s Power Grid

The US has deployed code inside Russia’s power grid and other targets as part of its work to push back against hacking and disinformation from Moscow, the New York Times reports. The revelation comes just three days after the news that a Russia-linked group called Xenotime has started laying the early groundwork for potential attacks on US power companies.

Inevitably, there are few specifics given the sensitivity of the topic. However, the work is being led by the US Cyber Command, an arm of the Pentagon. It’s permitted by a new law passed last summer, which approves “clandestine military activity” in cyberspace to “deter, safeguard or defend” against attacks.
