CRY0 is a ransomware group first observed in May 2026 with an apparent financial motivation, though its limited activity to date makes comprehensive attribution difficult. With only a single confirmed victim recorded and a targeting pattern focused on the transportation and automotive sectors, the group remains nascent and has not yet accumulated sufficient operational history to establish a well-documented profile in open-source intelligence reporting by organizations such as CISA, the FBI, Mandiant, or comparable security research firms. No confirmed country of origin, RaaS affiliation, or links to established threat actor clusters have been publicly documented at this time. Similarly, specific details regarding initial access vectors, tooling, encryption methodologies, or data exfiltration practices have not been publicly attributed to CRY0 by reputable sources, and no notable high-profile campaigns, record ransom demands, or law enforcement actions have been recorded against the group. Given its emergence in May 2026 and minimal victim count, CRY0 should be regarded as an emerging and unverified threat actor warranting continued monitoring, particularly within transportation and automotive industry verticals, as future activity may yield more substantive intelligence to support a fuller threat assessment. The group has been linked to 3 public disclosures across our corpus. First observed on a leak site on May 17, 2026; most recent post August 6, 2026. The operation is currently active.

If your organisation is affected
A listing by CRY0 means Hope's Windows 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, CISA (United States), as required for your jurisdiction.
- Monitor for the data appearing on CRY0's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
