Triplem is an obscure ransomware group that first emerged in March 2018, with limited public documentation suggesting they operate primarily for financial gain. The group's origin and potential affiliations remain unclear due to insufficient public reporting from major cybersecurity firms or law enforcement agencies. Based on available data, triplem appears to target healthcare organizations, with at least one documented victim in the United States healthcare and public health sector, though specific attack methodologies, tools, and encryption techniques have not been publicly detailed by reputable security researchers. No major campaigns, high-profile incidents, or significant law enforcement actions against triplem have been documented in open-source intelligence reports. The current operational status of triplem is unknown due to the limited public information available about this group's activities beyond the single recorded victim. The group has been linked to 1 public disclosures across our corpus. First observed on a leak site on March 30, 2018. The operation is currently inactive.

If your organisation is affected
A listing by triplem means MN Associates in Psychiatry and Psychology 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 triplem'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.
