Disclosure context

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 8 public disclosures across our corpus. First observed on a leak site on April 9, 2026; most recent post June 11, 2026. The operation is currently active.

If your organisation is affected

A listing by TiMc means oncologica 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, INCIBE-CERT (Spain), as required for your jurisdiction.
Monitor for the data appearing on TiMc'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.
