ShinyHunters Leaks 300,000 BreachForums User Records After Exiting Forum
ShinyHunters said it has abandoned BreachForums and released an updated database affecting more than 300,000 users of the cybercrime marketplace. Reports say the leak goes beyond basic credentials and includes full account profile and activity data, including usernames, email addresses, hashed passwords, salts, IP addresses, login metadata, and forum activity timestamps.
The group said maintaining the forum ecosystem became a "waste of time" after the FBI seizure of BreachForums and claimed that all currently active BreachForums domains are fake. ShinyHunters also threatened to publish fuller backups — including private messages, posts, and additional user data — unless the remaining forums shut down, while asserting it holds exploits for all MyBB 1.8 versions; the identity of the operators behind current BreachForums instances remains unclear, with speculation ranging from opportunistic criminals to possible law enforcement honeypots.
