AcidPour is a variant of AcidRain designed to impact a wider range of x86 architecture Linux devices. AcidPour is an x86 ELF binary that expands on the targeted devices and locations in AcidRain by including items such as Unsorted Block Image (UBI), Deice Mapper (DM), and various flash memory references. Based on this expanded targeting, AcidPour can impact a variety of device types including IoT, networking, and ICS embedded device types.[1]AcidPour is a wiping payload associated with the Sandworm Team threat actor, and potentially linked to attacks against Ukrainian internet service providers (ISPs) in 2023.[2]

AcidPour can identify specific files and directories within the Linux operating system corresponding with storage devices for follow-on wiping activity, similar to AcidRain.5
AcidPour can perform an in-depth wipe of victim filesystems and attached storage devices through either data overwrite or calling various IOCTLS to erase them, similar to AcidRain.7
AcidPour includes functionality to reboot the victim system following wiping actions, similar to AcidRain.8

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.
