crypto24
ransomware group · aka Crypto24, CZ (leak-site branding; used by some trackers) · Unknown; 2025 vendor research reported tooling and procedural overlaps suggesting possible ties to former Black Basta operators (unconfirmed) · active since Late 2024 / early 2025 (initial public tracking; exact date unknown)
Crypto24 is a ransomware and data-extortion group first publicly tracked in late 2024/early 2025, associated with double-extortion attacks in which stolen data is published on its leak site. Some vendor research published in 2025 reported tooling and procedural overlaps suggesting possible ties to former Black Basta operators, though attribution remains unconfirmed. The group targets large enterprises and institutions across multiple regions, with leak-site victims spanning education and research, healthcare, manufacturing, legal services, technology, and construction. This dashboard has tracked its leak site since 2026-08-31, recording 1 listed victim and a last post on that date, reflecting an intermittent claiming pattern rather than high-volume activity. The group's listing of Qatar Biomedical Research Institute (QBRI) drew attention in Qatar regional threat coverage for 2025-26.
- Double extortion: encrypts victim systems and publishes or threatens to publish stolen data on a leak site
- Selective big-game targeting of large enterprises and institutions, with named leak-site victims across the Americas, Europe, the Middle East, and Asia
- Reported tooling and procedural overlaps with former Black Basta operators in 2025 vendor analyses (unconfirmed)
- Intermittent leak-site cadence with multi-week to multi-month gaps between victim posts (observed in this dashboard's tracking)
- Initial access techniques and affiliate model: not consistently documented in public reporting (unknown)
- No specific exploited vulnerabilities (CVEs) widely attributed to the group in public reporting as of latest available research
