Researchers have found a new data wiping malware used in attacks against Ukrainian networks just as Russia moves troops into regions of Ukraine. Symantec shared the hash of the new data-wiper on Twitter, which is currently being detected by only 16/70 security engines on Virus Total. This data-wiper is the second one used against Ukrainian networks in the last two months.
