About TiMc

TiMc is an emerging ransomware group first observed in April 2026, with limited public documentation indicating financially-motivated cybercriminal activity targeting organizations primarily in Spain and Argentina. Given the recent emergence and limited victim count of three known cases, there is insufficient public intelligence from major security agencies or researchers to definitively establish the group's country of origin, operational structure, or potential affiliations with other threat actors. The group has demonstrated a targeting preference for business services and healthcare sectors based on observed victim patterns, though their specific attack methodologies, initial access vectors, encryption techniques, and whether they employ data exfiltration or multiple extortion tactics remain undocumented in available threat intelligence reporting. No major campaigns, high-profile incidents, or law enforcement actions against TiMc have been publicly reported by CISA, FBI, Mandiant, or other established security research organizations. The group's current operational status remains unclear due to limited visibility and the nascent nature of their observed activities. The group has been linked to 5 public disclosures across our corpus. First observed on a leak site on April 9, 2026; most recent post May 15, 2026. The operation is currently active.
