DarkForums is a niche data-leak platform that first appeared in 2022 and remains active. The community is small and the administrator team is largely inactive, but the site still hosts posts and may be worth monitoring if you're researching recent leaks or underground data markets.

BreachStars is widely regarded as the successor to BreachForums, largely due to its connections with the Scattered Spider group. The site remains in early development, but it has attracted much of the original BreachForums community, which continues to be active there.

LeakBase is a well-known but not overly popular forum, mainly because it doesn't feature a marketplace. Despite that, it's built a tight-knit community focused on cracking, logs, and combo lists, and it's definitely worth checking out.
