Founder of infidelity website AshleyMadison had his private emails leaked as part of the second data dump in the high-profile hacking case.
In addition to the one million of private email addresses, credit card details and account data deposited on the dark web earlier this week, the morality conscious attackers known as the Impact Team have released a second, even larger, pack of data on Thursday including private email messages of the website’s founder and CEO Noel Biderman.
In an obvious reaction to Biderman’s earlier denial of the authenticity of the leaked data, the hackers attached a direct message to the founder saying "Hey Noel, you can admit it's real now."
Overall, 20-gigabyte of data has reportedly been released on Thursday, almost twice as much as in the first data dump.
"Everything appears to be legit,” David Kennedy, founder and security consultant at TrustedSec, told Reuters, confirming the authenticity of the data. "We have portions downloaded and its confirmed legitimate thus far."
Source code for the website as well as smartphone apps and proprietary company data have been part of the dump, which a report in Vice Media's online technology site Motherboard described as bearing the same fingerprints as Tuesday's release.
The availability of the source code could allow other hackers to set up a similar site or find and exploit vulnerabilities on the actual site, which is still operating.
Among the email addresses leaked earlier were many UK civil servants, US government officials and executives of European and North America corporations. More than 15,000 of the leaked email addresses were reportedly military and governmental.
The Associated Press reported that hundreds of US government employees - including some with sensitive jobs in the White House, Congress and law enforcement agencies - used Internet connections in their federal offices to access and pay membership fees to the website.
The Pentagon said it was aware of reports that military email addresses were among those posted earlier in the week.
