As Promised, Over 9GB of Ashley Madison Data Dumped.

HACKERS WHO STOLE sensitive customer information from the cheating site AshleyMadison.com appear to have made good on their threat to post the data online.

A data dump, 9.7 gigabytes in size, was posted on Tuesday to the dark web using an Onion address accessible only through the Tor browser. The files appear to include account details and log-ins for some 32 million users of the social networking site, touted as the premier site for married individuals seeking partners for affairs. Seven years worth of credit card and other payment transaction details are also part of the dump, going back to 2007. The data, which amounts to millions of payment transactions, includes names, street address, email address and amount paid, but not credit card numbers; instead it includes four digits for each transaction that may be the last four digits of the credit card or simply a transaction ID unique to each charge. AshleyMadison.com claimed to have nearly 40 million users at the time of the breach about a month ago, all apparently in the market for clandestine hookups.

“Ashley Madison is the most famous name in infidelity and married dating,” the site asserts on its homepage. “Have an Affair today on Ashley Madison. Thousands of cheating wives and cheating husbands signup everyday looking for an affair…. With Our affair guarantee package we guarantee you will find the perfect affair partner.”

The data released by the hackers includes names, addresses and phone numbers submitted by users of the site, though it’s unclear if members provided legitimate details. A sampling of the data indicates that users likely provided random numbers and addresses, but files containing credit card transactions will yield real names and addresses, unless members of the site used anonymous pre-paid cards. One analysis of email addresses found in the data dump also shows that some 15,000 are .mil. or .gov addresses.

The data also includes descriptions of what members were seeking. “I’m looking for someone who isn’t happy at home or just bored and looking for some excitement,” wrote one member who provided an address in Ottawa and the name and phone number of someone who works for the Customs and Immigration Union in Canada. “I love it when I’m called and told I have 15 minutes to get to someplace where I’ll be greeted at the door with a surprise—maybe lingerie, nakedness. I like to ravish and be ravished … I like lots of foreplay and stamina, fun, discretion, oral, even willingness to experiment—*smile*”

Passwords released in the data dump appear to have been hashed using the bcrypt algorithm for PHP, but Robert Graham, CEO of Erratasec, says that despite this being one of the most secure ways to store passwords, “hackers are still likely to be able to ‘crack’ many of these hashes in order to discover the account holder’s original password.” If the accounts are still online, this means hackers will be able to grab any private correspondence associated with the account.
It’s notable, however, that the cheating site, in using the secure hashing algorithm, surpassed many other victims of breaches we’ve seen over the years who never bothered to encrypt customer passwords.

“We’re so used to seeing cleartext and MD5 hashes,” Graham says. “It’s refreshing to see bcrypt actually being used.”

Here’s how the hackers introduced the new data dump:

Following the intrusion last month, the hackers, who called themselves the Impact Team, demanded that Avid Life Media, owner of AshleyMadison.com and its companion site Established Men, take down the two sites. EstablishedMen.com promises to connect beautiful young women with rich sugar daddies “to fulfill their lifestyle needs.” The hackers didn’t target CougarLife, a sister site run by ALM that promises to connect older women with younger men.

“Avid Life Media has been instructed to take Ashley Madison and Established Men offline permanently in all forms, or we will release all customer records, including profiles with all the customers’ secret sexual fantasies and matching credit card transactions, real names and addresses, and employee documents and emails,” the hackers wrote in a statement following the breach.

To show they meant business, they posted sample files containing some of the stolen data, which included company financial information detailing employee salaries and documents mapping the company’s internal network.

The hackers appeared to target AshleyMadison and EstablishedMen over the questionable morals they condoned and encouraged, but they also took issue with what they considered ALM’s fraudulent business practices. Despite promising customers to delete their user data from the site for a $19 fee, the company actually retained the data on ALM’s servers, the hackers claimed. “Too bad for those men, they’re cheating dirtbags and deserve no such discretion,” the hackers wrote. “Too bad for ALM, you promised secrecy but didn’t deliver.”

Avid Life Media defiantly ignored the warnings and kept both sites online after the breach, promising customers that it had increased the security of its networks.

That wouldn’t matter for the customers whose data had already been taken. Any increased security would be too little too late for them. Now they face the greatest fallout from the breach: public embarrassment, the wrath of angry partners who may have been victims of their cheating, possible blackmail and potential fraud from anyone who may now use the personal data and bank card information exposed in the data dump.
