AcidRain is an ELF binary targeting modems and routers using MIPS architecture.[1]AcidRain is associated with the ViaSat KA-SAT communication outage that took place during the initial phases of the 2022 full-scale invasion of Ukraine. Analysis indicates overlap with another network device-targeting malware, VPNFilter, associated with Sandworm Team.[1] US and European government sources linked AcidRain to Russian government entities, while Ukrainian government sources linked AcidRain specifically to Sandworm Team.[2][3]

Enterprise ATT&CK only. Any Mobile or ICS rows on the same ATT&CK page are not carried.
AcidRain performs an in-depth wipe of the target filesystem and various attached storage devices through either a data overwrite or calling various IOCTLS to erase it.6
AcidRain iterates over device file identifiers on the target, opens the device file, and either overwrites the file or calls various IOCTLS commands to erase it.8

Standing S1125
Reach is how much of ATT&CK this malware touches. Coverage is how well defended each thing it does is, as a median per technique rather than a total — a total would just restate the reach. Each figure is ranked against all 825 ATT&CK software entries only where that population actually spreads. Where most of the population shares one value, a percentile would rank the tie instead of the entity, so the raw value is shown and no rank is claimed.
