Disclosure context

About mnt6

Given the limited public documentation available on mnt6, this appears to be a relatively obscure ransomware operation that emerged in April 2026 with only two known victims documented by security researchers. The group has demonstrated a focused targeting approach, conducting attacks against manufacturing and energy sector organizations specifically in Canada and New Zealand. Based on the small victim count and narrow geographic focus, mnt6 appears to operate as a small-scale independent ransomware group rather than a large RaaS operation, though their specific attack methodologies, encryption techniques, and data exfiltration practices have not been extensively documented in public threat intelligence reporting. No major campaigns or high-profile incidents have been attributed to this group, and their relatively recent emergence means there is insufficient public data from established security firms like Mandiant or government agencies like CISA and FBI regarding their operational tactics, techniques, and procedures. As of current reporting, mnt6 appears to remain active but maintains a low profile with minimal public visibility compared to more prominent ransomware families. The group has been linked to 3 public disclosures across our corpus. First observed on a leak site on April 30, 2026; most recent post May 2, 2026. The operation is currently active.

If your organisation is affected

A listing by mnt6 means Photonic 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, CCCS (Canada), as required for your jurisdiction.
Monitor for the data appearing on mnt6'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.
