Disclosure context

About babuk2

Babuk2 appears to be a recently emerged ransomware operation first observed in January 2025, representing either a new variant or successor to the original Babuk ransomware group, with apparent financial motivations based on their targeting patterns across multiple sectors and geographic regions. Given the limited timeframe since their emergence and the naming convention, this group likely operates independently or represents a rebrand/evolution of previous Babuk operations, though definitive attribution remains unclear due to the recency of their activities. Based on their targeting patterns across diverse sectors including public sector entities, technology companies, healthcare organizations, and manufacturing firms, the group appears to employ broad-spectrum attack methodologies typical of modern ransomware operations, though specific technical details regarding their initial access vectors, encryption methods, and extortion tactics have not yet been extensively documented by major security researchers. With 180 documented victims across multiple countries including significant activity in the United States, Brazil, India, Indonesia, and China within just the first month of 2025, Babuk2 has demonstrated a notably aggressive operational tempo, though specific high-profile incidents or ransom demands have not yet been publicly detailed by major cybersecurity firms or law enforcement agencies. The group appears to remain actively operational as of early 2025, though their recent emergence means long-term operational patterns and potential law enforcement responses are still developing. The group has been linked to 180 public disclosures across our corpus. First observed on a leak site on January 27, 2025; most recent post April 23, 2025. The operation is currently inactive.

If your organisation is affected

A listing by babuk2 means Access to Indian Ministry of Defence and Military Secret (DRDO) documents By Babuk Locker ... appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
Report the incident to your national CERT, CERT-In (India), as required for your jurisdiction.
Monitor for the data appearing on babuk2's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
