Defending Ukraine from Russian cyber attacks was ‘hand-to-hand combat’: Mandiant exec.

Russia launched a staggering number of destructive cyber attacks against Ukraine in the early days and weeks of its full-scale offensive that required digital security defenders to engage in “hand-to-hand combat in the cyber domain,” Sandra Joyce, the executive vice president of global intelligence at Mandiant, said at Semafor’s Securing the Digital Future event.


“From a cyber defender’s perspective, it was a dramatic back and forth,” Joyce said on Tuesday. “It was a harrowing first days, weeks and months.”


She said that Russia used more wipers — destructive malware that if successfully deployed destroys user data — against Ukraine in the first four months of the war than Mandiant saw in the past eight years while supporting Ukraine’s digital defenses.
