Sarcoma threatens to release data in a week if ransom is not paid.
The Taiwanese printed circuit board manufacturer Unimicron had its systems compromised in an attack by the newly emergent Sarcoma ransomware operation.
According to BleepingComputer, the attackers claimed to have stolen 377GB of data, including SQL files. The Sarcoma group has threatened to expose the data next week, should the firm refuse to pay the demanded ransom.
Despite confirming that its China-based subsidiary Unimicron Technology (Shenzhen) Corp., had been disrupted by a ransomware intrusion on January 30th, Unimicron did not disclose being subjected to a data breach, as it noted an ongoing investigation into the incident.
Attacks by Sarcoma were detailed by Red Piranha to have involved phishing emails and the exploitation of n-day flaws, in addition to
supply chain intrusions but the group's origins continue to be a mystery.
