In June 2021, the organization was identified as the target of a ransomware attack carried out by the Prometheus group, which had links to the REvil operation. The attackers deployed Thanos ransomware, a 32‑bit .NET executable that employed obfuscation, base64 encoding, and AES encryption to lock files. The malware also terminated processes such as excel.exe and steam.exe, altered firewall settings, and dropped ransom notes in both HTA and text formats. Analysis of the attack revealed plaintext strings confirming the ransomware’s functionality and showed deliberate service interruptions intended to maximize disruption before encryption. No information on ownership, parent‑subsidiary relationships, or structural changes is available in the provided context.
