Black Berserk is a relatively unsophisticated ransomware strain analyzed in late 2023. It operates under a single‑extortion model—encrypting files and demanding payment, with no documented abilities or threats for data exfiltration or public leaks. In observed cases, the malware appends the .Black extension to encrypted files (e.g., 1.jpg.Black) and leaves a ransom note titled Black_Recover.txt, which urges victims to make contact to negotiate payment or test decryption with benign files. The infection method appears opportunistic, delivered via isolated incidents or broad malware distribution—not linked to targeted campaigns or infrastructure. There is no evidence of it functioning as a RaaS operation or targeting any specific victim profiles or sectors.

Ransomware

Babuk‑Locker emerged in early 2021 as a Ransomware‑as‑a‑Service (RaaS) gang targeting high‑value “big game” enterprises across sectors like healthcare, telecommunications, finance, education, and government. It initially deployed crypto-ransomware—encrypting files using ChaCha8 encryption with keys secured via elliptic‑curve Diffie‑Hellman—and later added a double‑extortion model involving data theft and leak site threats. Notable incidents include attacks on the Washington, D.C. Metropolitan Police Department and other organizations. In mid‑2021, Babuk’s source code was leaked, prompting both a fragmentation of its core operations and emergence of variants like Babuk Tortilla and Babuk V2. Affiliates exploited vulnerabilities in ESXi hypervisors to deliver destructive variants, and law enforcement actions eventually disrupted key operators.
