Disclosure context

About Moneymessage

Moneymessage is a relatively new ransomware group that emerged in March 2023, operating with primarily financial motivations and targeting organizations across multiple sectors globally. Given the group's recent emergence and limited public documentation from major security agencies, detailed information about their origin and affiliations remains largely unknown, though their targeting patterns suggest they may operate as a smaller independent operation rather than a large-scale RaaS model. The group has demonstrated a broad targeting approach across healthcare, business services, public sector, government, and financial organizations, with their 29 documented victims spanning geographically diverse regions including the United States, Italy, Argentina, Bangladesh, and Russia, though specific attack methodologies and technical capabilities have not been extensively documented by major threat intelligence firms. Notable campaigns and high-profile attacks attributed to Moneymessage have not been widely reported by established security researchers or law enforcement agencies, likely due to the group's relatively recent emergence and smaller scale of operations compared to more prominent ransomware families. The group appears to remain active as of available reporting, though comprehensive analysis of their current operational status is limited by the lack of detailed public documentation from authoritative sources such as CISA, FBI, or major cybersecurity firms. The group has been linked to 34 public disclosures across our corpus. First observed on a leak site on March 29, 2023; most recent post July 9, 2026. The operation is currently active.

If your organisation is affected

A listing by Moneymessage means Meteksan Defence Industry 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.
Monitor for the data appearing on Moneymessage'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.
