Disclosure context

About coinbasecartel

CoinbaseCartel is a ransomware group that emerged in September 2025 with financially motivated operations targeting organizations across multiple sectors and geographic regions. The group has demonstrated significant activity in a short timeframe, compromising at least 102 known victims primarily across the United States, United Arab Emirates, Germany, Canada, and Brazil. Their targeting patterns show a preference for technology companies, financial services organizations, manufacturing entities, and consumer services businesses, suggesting an opportunistic approach focused on organizations likely to have both valuable data and the financial resources to pay ransoms. Given the group's recent emergence and limited public documentation from established threat intelligence sources, details regarding their specific attack methodologies, infrastructure, and organizational structure remain largely unconfirmed by major cybersecurity firms or law enforcement agencies. The group appears to maintain active operations as of late 2025, though comprehensive analysis of their tactics, techniques, and procedures awaits further investigation and reporting by established threat intelligence organizations. The group has been linked to 176 public disclosures across our corpus. First observed on a leak site on September 15, 2025; most recent post May 16, 2026. The operation is currently active.

Attack summary

Severity: high — ENGIE is a critical infrastructure operator (energy sector) active in over 70 countries; confirmed data publication by the threat actor against such a systemically important entity constitutes a high-severity incident even without explicit enumeration of data types, as any compromise of operational or business data at this scale poses significant risk.

The coinbasecartel group claims to have attacked ENGIE and has published data ('data_published' status), though the leak post does not specify whether encryption, exfiltration, or both occurred, nor does it detail the volume or nature of the data disclosed.
