Disclosure context

About Losttrust

Losttrust is a relatively new ransomware group that emerged in September 2023, operating with apparent financial motivations and demonstrating a broad international targeting scope across multiple sectors. The group's origin and affiliations remain largely undocumented by major threat intelligence organizations, with limited public reporting from established security firms regarding their operational structure or potential ransomware-as-a-service connections. Based on available victim data, Losttrust appears to employ opportunistic targeting methods, having compromised 53 known victims across diverse geographic regions including the United States, Italy, Germany, Argentina, and India, with particular focus on education, legal services, media organizations, food and agriculture companies, and government entities. The specific attack methodologies, initial access vectors, encryption techniques, and extortion tactics employed by Losttrust have not been extensively documented in public threat intelligence reports from major security vendors or law enforcement agencies. Given the group's recent emergence and limited visibility in established threat intelligence channels, their current operational status and activity levels remain unclear, though the breadth of their reported victim base suggests ongoing operations as of recent observations. The group has been linked to 53 public disclosures across our corpus. First observed on a leak site on September 26, 2023. The operation is currently inactive.

If your organisation is affected

A listing by Losttrust means Popovici Niu Stoica & Asociaii 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.
  • Monitor for the data appearing on Losttrust'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.
