Disclosure context

About Monti

Monti is a ransomware group that emerged in December 2022, operating with primarily financial motivations through targeted encryption attacks against organizations across multiple sectors. The group's origin and specific affiliations remain largely undocumented in public threat intelligence reports, though their operational patterns suggest they function as an independent ransomware operation rather than a established Ransomware-as-a-Service model. Monti's attack methodology and specific technical details regarding initial access vectors, encryption methods, and data exfiltration practices have not been extensively documented in publicly available threat intelligence from major security firms or government agencies. The group has reportedly compromised approximately 110 victims since their emergence, with their targeting primarily focused on organizations in the United States, Canada, Germany, France, and Italy, showing a particular preference for business services, healthcare, manufacturing, and technology sectors. Limited public documentation exists regarding specific notable campaigns or high-profile attacks attributed to Monti, reflecting the group's relatively recent emergence and lower profile compared to more established ransomware operations. As of current reporting, Monti appears to remain an active threat, though comprehensive intelligence on their current operational status is limited in publicly available sources from major cybersecurity organizations and law enforcement agencies. The group has been linked to 110 public disclosures across our corpus. First observed on a leak site on December 7, 2022; most recent post May 8, 2025. The operation is currently inactive.

If your organisation is affected

A listing by Monti means Spine West 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 Monti'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.
