US intelligence agencies are looking into a cyber attack that disrupted broadband satellite access in Ukraine.

Western spies are said to be attempting to identify the hackers who carried out the attack concurrently with Russia’s invasion of Ukraine.

According to IT News, the investigation was revealed by “three people with direct knowledge” of the attack.

The US National Security Agency, the French cyber security firm ANSSI, and Ukrainian intelligence are among those involved in the investigation.

They’re looking into whether the hackers were aided by the Russian government.

Experts believe the satellites were targeted in order to make it difficult for Ukraine’s military to communicate during the initial Russian invasion.
