Hackers from Raidforums just lately breached the location of rival hacking discussion board Cracked.to and spilled information for greater than 321,000 of its members. The hackers did so whereas a few of their victims had been discussing cracking Fortnite accounts, promoting software program exploits, and interesting in different doubtlessly unlawful actions.

In all, the dump posted on Friday to Raidforums.com uncovered 749,161 distinctive electronic mail addresses, breach-notification service HaveIBeenPwned reported. The printed information additionally included customers’ IP addresses, usernames, non-public messages, and passwords saved as bcrypt hashes. The database was generated by web site discussion board software myBB. Cracked.to describes itself as a discussion board that gives “cracking tutorials, instruments, combolists, market and plenty of extra stuff!” Raidforums, in the meantime, gives boards on most of the similar subjects.

Ars reviewed a 2.11 gigabyte file printed by Raidforums and located it contained practically 397,000 non-public messages, many who aired the sorts of particulars most hackers strenuously keep away from disclosing. The small print included the usernames, electronic mail addresses, and IP addresses of individuals looking for to purchase, promote, or help software program or providers for cracking accounts for fashionable online game Fortnite.

“Freshly cracked Fortnite accounts with skins captured,” reads the topic of 1 message. “Easy methods to change electronic mail on cracked Fortnite accounts,” the topic of one other says. Different customers promote providers for exploiting CVE-2019-20250, a vital vulnerability within the WinRAR file-compression program, which was being actively exploited earlier this yr to put in a bunch of nasty malware on weak computer systems.

It is possible that most of the folks accessing Cracked.to did so from IP addresses anonymized by Tor or another means. They most likely used electronic mail addresses and person names that had been additionally equally anonymized, or no less than pseudo-anonymized. Nonetheless, all it takes for regulation enforcement or rival hackers to pounce is to slide up simply as soon as and use the unsuitable IP tackle. The database posted on Friday ought to put all of these folks on discover.

The dump additionally serves as a cautionary story to web site directors all over the place that databases can and shall be compromised. It is nonetheless not clear how the database was obtained. Raidforums proprietor, developer, and host “All-powerful” instructed Ars it was via an “exploit,” however All-powerful offered no particulars past that. If true, that may possible imply myBB or one other piece of software program utilized by the location was hacked. Ars could not rule out the chance an administrator password was obtained, or another means.

A prime administrator at Cracked.to, in the meantime, claimed in July that “an previous individual of my belief has discussion board backups that incorporates the database and folder recordsdata.” A number of months earlier, the Cracked.to admin stated, the location had transformed from the very weak default myBB password-hashing scheme to one thing a lot stronger. In mild of the breach, the location required customers to alter their passwords.

It seems that was a significant coup that prevented the breach from being a lot worse. The brand new scheme used the industrial-strength bcrypt hashing operate with a piece issue of 12. That makes it unattainable to guess the overwhelming majority of hashes with out spending prohibitively massive quantities of money and time. Weak passwords might nonetheless be cracked, however past that, the hashes aren’t of a lot use. Had Cracked.to continued to make use of the previous scheme, cracking nearly all of hashes inside a matter of days or perhaps weeks would have been trivial.

In an interview, the Cracked.to administrator stated he regretted the leak, significantly these involving non-public messages.

“With little question, non-public messages being leaked in plaintext is the worst factor about the entire database breach,” the administrator, who makes use of the deal with floraiN, stated in an encrypted chat with Ars. “Nevertheless as a discussion board proprietor you possibly can’t actually management what individuals are coping with in DMs until you look them up immediately within the database.”

He stated the IP tackle of particular non-public messages was encoded, however that the dump included the IPs of every person’s first and most up-to-date go to. floraiN stated these particulars might nonetheless be used to trace some customers down. The admin, in the meantime, is vowing to not take the breach mendacity down.

“There shall be penalties for the discussion board that’s chargeable for distributing the backup and for the individual that leaked it,” floraiN stated in an replace posted on Friday.
