AcidPour, as researchers from security firm Sentinel One have named the new malware, has stark similarities to AcidRain, a wiper discovered in March 2022 that Viasat has confirmed was used in the attack on its modems earlier that month. Wipers are malicious applications designed to destroy stored data or render devices inoperable. Viasat said AcidRain was installed on more than 10,000 Eutelsat KA-SAT modems used by the broadband provider seven days prior to the March 2022 discovery of the wiper. AcidRain was installed on the devices after attackers gained access to the company’s private network.
