Leakbase, a Web site that indexed and sold access to billions of usernames and passwords stolen in some of the world largest data breaches, has closed up shop. A source close to the matter says the service was taken down in a law enforcement sting that may be tied to the Dutch police raid of the Hansa dark web market earlier this year.
Last week, KrebsOnSecurity detailed how BackConnect Inc. — a company that defends victims against large-scale distributed denial-of-service (DDoS) attacks — admitted to hijacking hundreds of Internet addresses from a European Internet service provider in order to glean information about attackers who were targeting BackConnect. According to an exhaustive analysis of historic Internet records, the BackConnect appears to have a history of such “hacking back” activity.
