[This is Part III in a series on research conducted for a recent Hulu documentary on the 2015 hack of marital infidelity website AshleyMadison.com.]
In 2019, a Canadian company called Defiant Tech Inc. pleaded guilty to running LeakedSource[.]com, a service that sold access to billions of passwords and other data exposed in countless data breaches. KrebsOnSecurity has learned that the owner of Defiant Tech, a 32-year-old Ontario man named Jordan Evan Bloom, was hired in late 2014 as a developer for the marital infidelity site AshleyMadison.com. Bloom resigned from AshleyMadison citing health reasons in June 2015 — less than one month before unidentified hackers stole data on 37 million users — and launched LeakedSource three months later.
For the second time in as many years, hackers have compromised Verticalscope.com, a Canadian company that manages hundreds of popular Web discussion forums totaling more than 45 million user accounts. Evidence of the breach was discovered just before someone began using that illicit access as a commercial for a new paid search service that indexes consumer information exposed in corporate data breaches.
Late last month, multiple news outlets reported that unspecified law enforcement officials had seized the servers for Leakedsource.com, perhaps the largest online collection of usernames and passwords leaked or stolen in some of the worst data breaches — including billions of credentials for accounts at top sites like LinkedIn, Myspace, and Yahoo.
In a development that may turn out to be deeply ironic, it seems that the real-life identity of Leakedsource’s principal owner may have been exposed by many of the same stolen databases he’s been peddling.
A 2012 data breach that was thought to have exposed 6.5 million hashed passwords for LinkedIn users instead likely impacted more than 117 million accounts, the company now says. In response, the business networking giant said today that it would once again force a password reset for individual users thought to be impacted in the expanded breach.
