CyberVolk, a pro-Russian hacktivist group, has launched a new ransomware-as-a-service (RaaS) called VolkLocker, which has a significant flaw. Researchers from SentinelOne discovered that VolkLocker contains a hard-coded master key, allowing victims to decrypt their files without paying the ransom. This ransomware, which surfaced in August 2025, targets Windows systems and is part of an ongoing trend of ransomware attacks that can disrupt businesses and individuals alike. The presence of this flaw means that while the ransomware may still be a concern, victims have a potential way to recover their data without succumbing to the attackers' demands. This incident underscores the ongoing battle between cybercriminals and security researchers, as vulnerabilities in ransomware can lead to unexpected outcomes for victims.
