Hacker who goes online under the nickname “KingNull” has leaked online a database of the largest free web hosting provider for dark web services, Daniel’s Hosting (DH), that was obtained in a hack earlier this year. Nearly 7,600 dark web sites have been taken offline following the attack.

At the time, the owner of the hosting service Daniel Winzen said that hackers compromised his website and deleted all hosting-related databases. Later, the attacker deleted Daniel Hosting's database account and created a new one for future use. After the hack Winzen decided to shut down the hosting portal and, for now, there is no set date for relaunching the service.

According to ZDNet’s report, KingNull has uploaded a copy of DH's stolen database on a file-hosting portal. The leaked data includes 3,671 email addresses, 7,205 passwords, and 8,850 private keys of the domains attached to the dark web sites.

According to threat intelligence firm Under the Breach that analyzed the leaked database, published data contains “sensitive information on the owners and users of several thousand darknet domains”, and that leaked data “could substantially help law enforcement track the individuals running or taking part in illegal activities on these darknet sites.”
