About the victim

AI dossier — public-source company profile

BreachForums is a notorious cybercrime and data-leak forum that has operated across multiple iterations and domains following successive law enforcement takedowns. It has historically served as a marketplace for stolen data, credentials, and hacking tools. The forum has no legitimate corporate structure and operates anonymously across various clearnet and dark-web domains.

Industry: Cybercrime Forum / Underground Marketplace

Attack summary

Severity: high — Threatened disclosure includes IP addresses, email addresses, and private messages of forum members at scale — constituting significant PII exfiltration with potential to expose identities of individuals involved in cybercriminal activity; data is claimed to be in hand and release is conditional rather than speculative.

Hunters International claims to have seized control of BreachForums infrastructure following an FBI seizure on 10 October 2025, and threatens to publish full forum backups — including private messages, email addresses, IP addresses, and posts — if copycat forums continue to operate.

What the group claims

BreachForums has been run by many fakes, but by us, following the FBI seizure on 10 Oct 2025. Maintaining such an ecosystem is a waste of our time. There was an unauthorised leak on 9 Jan 2026. Ever since then, false personas going by “N/A“ and “Indra“ were successfully able to restore a similar-looking “legitimate“ forum. All the current forums are fake [ .sb, .ac, .fi, .bf, .us, ect.]. If they continue to exist, we'll leak all the BF backups, including every private message, emails, IP addresses, posts, ect. We have exploits for all 1.8 versions of MyBB.

Disclosure context

About Hunters International

Hunters International is a ransomware group that emerged in October 2023, operating with primarily financial motivations and demonstrating rapid expansion in their victim targeting across multiple sectors. The group's origin and specific affiliations remain largely undocumented by major security agencies, though their operational patterns suggest they function as an independent ransomware operation rather than a established Ransomware-as-a-Service model. Based on publicly available victim data, Hunters International has demonstrated a preference for targeting business services, technology, and manufacturing sectors, with their attacks primarily concentrated in English-speaking countries including the United States, France, and the United Kingdom. Their attack methodology and specific technical capabilities have not been extensively documented by major threat intelligence organizations such as CISA, FBI, or Mandiant, limiting detailed analysis of their initial access vectors, encryption methods, or data exfiltration practices. With 388 documented victims since their emergence, the group has shown consistent activity levels, though specific high-profile campaigns or notable ransom demands have not been widely reported in public threat intelligence reports. As of current reporting, Hunters International appears to remain active with no documented law enforcement disruptions or operational changes reported by major cybersecurity agencies. The group has been linked to 695 public disclosures across our corpus. First observed on a leak site on October 20, 2023; most recent post March 26, 2026. The operation is currently active.

If your organisation is affected

A listing by Hunters International means BreachForums version 5 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 Hunters International'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.
