Description
The Prestige ransomware emerged in October 2022, with the first attacks detected on October 11 targeting organizations primarily in the transportation and logistics sectors across Ukraine and Poland. Microsoft attributed the activity to a novel ransomware operation based on forensic evidence, though no specific threat actor group was identified in the disclosure. The attacks coincided with heightened geopolitical tensions in the region but lacked explicit attribution to state-sponsored activity. Initial infection vectors were not fully detailed, though compromised IT infrastructure served as the ransomware delivery mechanism. Attackers employed living-off-the-land techniques, leveraging legitimate system administration tools and processes to evade detection while deploying the payload. The ransomware appended the .PRESTIGE extension to encrypted files and left ransom notes directing victims to contact attackers via a Tox-based communication channel. Multiple organizations reported operational disruptions, particularly affecting supply chain operations and freight management systems.

Microsoft's incident response teams engaged with affected entities to contain the ransomware's spread by isolating compromised systems and terminating malicious processes. Forensic analysis revealed the attackers selectively targeted VMware ESXi virtual machines and Windows systems, encrypting critical data stores and virtual hard drives. Recovery efforts involved restoring data from backups where available, though some organizations experienced prolonged downtime due to the encryption of operational databases. The incident impacted multiple companies within Poland's transportation sector, disrupting cross-border freight operations between Poland and Ukraine. No ransom payment amounts or data exfiltration claims were publicly verified. Microsoft Threat Intelligence Center (MSTIC) disseminated indicators of compromise to enable network defenders to identify similar attacks, including file hashes and behavioral patterns associated with the ransomware's execution chain.
