In the field of computer security, a wiper is a kind of malware that is designed to erase (wipe) the hard drive of the computer that it infects, therefore intentionally erasing data and applications on the infected machine.

According to SentinelOne, this might indicate that the attackers are unfamiliar with the filesystem and firmware of the targeted devices, or that they are attempting to create a reusable tool.

AcidRain was discovered on March 15 after being uploaded to the VirusTotal malware analysis platform from an IP address in Italy as a 32-bit MIPS ELF binary with the filename “ukrop.” AcidRain is a variant of the AcidRain family of viruses.
