“AcidRain” Wiper Malware Attack on Viasat

A cyberattack disrupted broadband satellite internet access coinciding with Russia’s invasion of Ukraine. The cyberattack disabled modems that communicate with Viasat Inc’s KA-SAT satellite, which supplies internet access to some customers in Europe, including Ukraine. More than two weeks later some remain offline. “This appears to have initially started with the KA-SAT service in Ukraine and then spread to almost the entire KA-SAT footprint.” SentinelLabs researchers discovered a new wiper malware they named ‘AcidRain’ which was confirmed by Visat as used in the attack on 24th against the modems.
