Disclosure context

About Dan0N

Dan0N is an emerging ransomware group that first appeared in April 2024, operating with primarily financial motivations and demonstrating a focused targeting approach across multiple sectors. Based on limited public information, the group's origin and affiliations remain unclear, with insufficient data to determine whether they operate as an independent entity or as part of a Ransomware-as-a-Service model. The group has demonstrated capability to compromise organizations across diverse sectors including business services, technology, healthcare, and financial services, though specific attack vectors and technical methodologies have not been extensively documented by major security research organizations. Dan0N has maintained a relatively low profile compared to established ransomware operations, with 33 documented victims primarily concentrated in the United States, Ireland, and South Korea, suggesting either targeted regional focus or opportunistic attacks against accessible infrastructure in these countries. The group appears to remain active as of current reporting, though the limited public documentation from established threat intelligence sources indicates they have not yet achieved the notoriety or scale of operations that would trigger significant law enforcement attention or comprehensive technical analysis from major security firms. The group has been linked to 33 public disclosures across our corpus. First observed on a leak site on April 25, 2024; most recent post August 23, 2024. The operation is currently inactive.

If your organisation is affected

A listing by Dan0N means mmtransport.com 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 Dan0N'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.
