White House Warns of Possible Russian Cyberattacks
The White House has issued its starkest warning that Russia may be planning cyberattacks against critical-sector U.S. companies amid the Ukraine invasion.
Context: The alert comes after Russia has lobbed a series of digital attacks at the Ukrainian government and critical industry sectors. But there’s been no sign so far of major disruptive hacks against U.S. targets even as the government has imposed increasingly harsh sanctions that have battered the Russian economy.
- The public alert followed classified briefings government officials conducted last week for more than 100 companies in sectors at the highest risk of Russian hacks, Neuberger said. The briefing was prompted by “preparatory activity” by Russian hackers, she said.
- U.S. analysts have detected scanning of some critical sectors’ computers by Russian government actors and other preparatory work, one U.S. official told my colleague Ellen Nakashima on the condition of anonymity because of the matter’s sensitivity. But whether that is a signal that there will be a cyberattack on a critical system is not clear, Neuberger said.
- Neuberger declined to name specific industry sectors under threat but said they’re part of critical infrastructure —a government designation that includes industries deemed vital to the economy and national security, including energy, finance, transportation and pipelines.
