BreachForums version 5
Attack Intelligence
BreachForums version 5 was compromised in a ransomware attack attributed to shinyhunters in March 2026. The organization, operating in an undisclosed sector in Unknown, was added to the group's data leak site as part of an extortion campaign.
shinyhunters operates as a financially motivated ransomware-as-a-service (RaaS) operation, exfiltrating sensitive data and threatening public disclosure to pressure victims into paying ransom demands.
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.
Intelligence correlations link this incident to 1 vulnerability(ies) including CVE-2026-35273, which may have been leveraged as initial access vectors or for lateral movement.
