What the group claims

The Institute was established in 1970 as an initiative of the Government of Trinidad and Tobago with financial and technical support from the United Nations Development Programme (UNDP) and United Nations Industrial Development Organization (UNIDO). It was incorporated under Act of Parliament no. 19 of 1971, which was subsequently amended by Act no. 33 of 1981. Although established with funding from the Government and the aforementioned international agencies, at the outset the Institute's mandate catered for the provision of services to the Caribbean region. Traditionally, the Institute's service base has been quite diverse, comprising the provision of laboratory-based analytical and engineering services (testing utilizing state-of-the-art, internationally accredited facilities), as well as associated consultancy support, training and applied Research and Development (primarily investigative/developmental work). The base was expanded in 2014 with the establishment of CARIRI's flagshipdevelopment, the Centre for Enterprise Development (CED). Presently, the Institute provides a range of technology/technology based support services to the public and private sectors, encompassing Laboratory testing/analytical services via our St Augustine and Macoya laboratory facilities. The Institute provides Research, Entrepreneurship, Innovation, Development (REID) and ICT Consultancy Services through our Innovation Ecosystem at the Centre for Enterprise Development (CED), Freeport. company is headquartered in The University of the West Indies St Augustine Campus Trinidad and Tobago 62 Employees.

Disclosure context

About Medusa

Medusa, also known as MedusaLocker, is a financially motivated ransomware group that emerged in November 2022 and has since compromised 568 known victims across multiple countries. The group's origin and specific affiliations remain unclear from publicly available intelligence, though their operational patterns suggest they function as an independent ransomware operation rather than a documented Ransomware-as-a-Service model. Medusa primarily targets organizations in the United States, United Kingdom, Canada, Italy, and Australia, with a focus on business services, healthcare, manufacturing, and technology sectors, employing typical ransomware tactics including data encryption and likely exfiltration for double extortion purposes, though specific technical methodologies and initial access vectors have not been extensively documented in public threat intelligence reports. While the group has maintained a relatively high victim count since its emergence, detailed information about specific notable campaigns, high-profile victims, or major ransom demands has not been widely reported by major cybersecurity firms or law enforcement agencies. As of current intelligence assessments, Medusa appears to remain active in the threat landscape, continuing to target organizations across their established geographic and sectoral preferences. The group has been linked to 635 public disclosures across our corpus. First observed on a leak site on November 15, 2022; most recent post May 5, 2026. The operation is currently active.

If your organisation is affected

A listing by Medusa means Cariri 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 Medusa'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.
