New AcidRain Linux Malware Variant “AcidPour” Found Targeting Ukraine

SentinelLabs researchers disclosed "AcidPour," a new Linux x86 variant of the AcidRain wiper observed in Ukraine; compiled for x86 rather than MIPS, it shares some strings with AcidRain but has a distinct codebase and expanded wiping logic that references UBI and LVM virtual block devices, suggesting broader destructive targets. The scope and specific victims remain unclear; SentinelLabs has alerted stakeholders and recommended defensive measures such as user training against phishing.
