Posters at Soyjack Party, a rival imageboard that began as a 4chan offshoot, claimed responsibility for the hack. But as with all posts on these intensely insular boards, it's difficult to separate fact from fiction. The thread shows screenshots of what appear to be 4chan's PHP admin interface, among other screenshots, that suggest extensive access to 4chan's databases of posts and users.
