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.

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.
