Darkfield

Operator dossier

Apt73 (also tracked as Eraleign) is a ransomware operator no longer publishing new disclosures. Darkfield has indexed 161 public victims claimed by this operator between April 22, 2024 and July 6, 2026. APT73 is a recently emerged ransomware group that began operations in April 2024, with financial motivation as their primary driver based on their targeting patterns across multiple high-value sectors. The group has demonstrated rapid growth in their operational tempo, accumulating 78 documented victims within their first months of activity. Their targeting methodology shows a preference for English-speaking markets and major economies, with the United Kingdom and United States representing their primary focus areas, followed by significant activity in India, Brazil, and France. The group exhibits a clear preference for high-value sectors including business services, technology, financial services, and healthcare organizations, suggesting a calculated approach to victim selection based on potential payment capability and operational impact. Given the group's recent emergence and limited public documentation from major threat intelligence sources, specific details regarding their initial access vectors, tooling, encryption methods, or organizational structure remain largely unconfirmed by authoritative sources such as CISA, FBI, or established security research firms. The group's current operational status appears active based on the timeline of their emergence, though comprehensive analysis of their capabilities and infrastructure requires additional intelligence gathering and documentation by security researchers.

How we know this. Operator profiles on Darkfield are built from continuous monitoring of every leak site the group is known to operate, cross-correlated with community-curated feeds (RansomLook, ransomware.live, RansomWatch, MISP-galaxy). Status flips from active to inactive when no new disclosure appears for 60 days. MITRE ATT&CK mappings shown in the interactive section below are sourced from CISA, vendor analysis, and the MITRE community catalog — we attribute each technique back to its source. Aliases reflect operator re-brands and affiliate splits.
