About the victim

AI dossier — public-source company profile

BreachForums is a well-known underground hacking and data-breach forum that has operated under multiple administrators following repeated law enforcement seizures, including an FBI takedown. It facilitates the buying, selling, and sharing of stolen data and hacking tools. The forum has gone through numerous iterations and domain changes across its history.

Industry: Cybercrime & Hacking Forum

Attack summary

Severity: high — The threatened data includes PII such as IP addresses and email addresses of forum members at scale, along with private communications. Full exposure of this data would de-anonymise a large number of individuals, many of whom may be threat actors or victims themselves, representing significant downstream harm.

ShinyHunters claims to hold full backups of BreachForums obtained after the FBI seizure on 10 Oct 2025, and threatens to publish all private messages, email addresses, IP addresses, and posts if impostor forums continue operating. The group is leveraging possession of the data as coercion rather than a traditional ransomware demand.

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 shinyhunters

Based on the limited publicly available information, shinyhunters appears to be a recently emerged ransomware group first observed in October 2025, primarily motivated by financial gain through extortion activities targeting organizations across multiple sectors. The group's origin and potential affiliations remain unclear due to their recent emergence, and there is insufficient public documentation to determine whether they operate as a Ransomware-as-a-Service model or as an independent entity. Their attack methodology and specific technical capabilities have not been extensively documented by major threat intelligence firms, though their targeting pattern suggests a broad opportunistic approach rather than sector-specific specialization. The group has reportedly victimized approximately 77 organizations, with primary targeting focused on the United States, France, Japan, Germany, and Australia, showing particular interest in consumer services, technology, financial services, transportation and logistics, and education sectors. Given the group's very recent emergence in late 2025, there are no widely reported major campaigns or high-profile incidents documented by established security research organizations, and no known law enforcement actions have been publicly reported against this group. The current operational status of shinyhunters remains active based on available reporting, though comprehensive threat intelligence profiles from major security firms like Mandiant, CrowdStrike, or government agencies have not yet been published due to the group's recent appearance in the threat landscape. The group has been linked to 122 public disclosures across our corpus. First observed on a leak site on October 3, 2025; most recent post June 12, 2026. The operation is currently active.

If your organisation is affected

A listing by shinyhunters 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 shinyhunters'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.
