Disclosure context

About Embargo

Embargo is a ransomware group that emerged in April 2024, operating with primarily financial motivations and demonstrating a focus on high-value targets across multiple sectors. The group has been observed targeting victims predominantly in the United States, Singapore, India, and France, with particular emphasis on technology, healthcare, manufacturing, business services, and financial sectors. Given the group's recent emergence and limited public documentation from major threat intelligence sources, specific details about their country of origin, operational structure, and technical methodologies remain largely unconfirmed by established security research organizations. With 37 known victims identified since their emergence, Embargo appears to follow established ransomware operational patterns typical of financially-motivated cybercriminal groups, though comprehensive analysis of their attack vectors, encryption methods, and extortion tactics has not yet been extensively documented by major cybersecurity firms or government agencies. The group's targeting of critical infrastructure sectors including healthcare and financial services aligns with broader ransomware trends observed throughout 2024, though specific notable campaigns or high-profile attacks have not been widely reported in public threat intelligence reporting. As of current observations, Embargo appears to remain active, though the limited timeframe since their emergence and sparse public documentation makes definitive assessment of their operational status challenging without additional confirmed reporting from established threat intelligence sources. The group has been linked to 48 public disclosures across our corpus. First observed on a leak site on April 21, 2024; most recent post August 20, 2026. The operation is currently active.

If your organisation is affected

A listing by Embargo means Ludlum Measurements, Inc. 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 Embargo'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.
