The data released by the hacker or hackers – which self-identify as The Impact Team – includes sensitive internal data stolen from Avid Life Media (ALM), the Toronto-based firm that owns AshleyMadison as well as related hookup sites Cougar Life and Established Men

Large caches of data stolen from online cheating site AshleyMadison have been posted online by an individual or group that claims to have completely compromised the company’s user databases, financial records and other proprietary information. Have an affair.”

Reached by KrebsOnSecurity late Sunday evening, ALM Chief Executive Noel Biderman confirmed the hack, and said the company was “working diligently and feverishly” to take down ALM’s intellectual property. Indeed, in the short span of 30 minutes between that brief interview and the publication of this story, several of the Impact Team’s Web links were no longer responding.

Besides snippets of account data apparently sampled at random from among some 40 million users across ALM’s trio of properties, the hackers leaked maps of internal company servers, employee network account information, company bank account data and salary information.

The compromise comes less than two months after intruders stole and leaked online user data on millions of accounts from hookup site AdultFriendFinder.

In a long manifesto posted alongside the stolen ALM data, The Impact Team said it decided to publish the information in response to alleged lies ALM told its customers about a service that allows members to completely erase their profile information for a $19 fee.

The still-unfolding leak could be quite damaging to some 37 million users of the hookup service, whose slogan is “Life is short

According to the hackers, although the “full delete” feature that Ashley Madison advertises promises “removal of site usage history and personally identifiable information from the site,” users’ purchase details – including real name and address – aren’t actually scrubbed.

“Full Delete netted ALM $1.7mm in revenue in 2014. “Users almost always pay with credit card; their purchase details are not removed as promised, and include real name and address, which is of course the most important information the users want removed.”

“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 other websites may stay online.”

It’s unclear how much of the AshleyMadison user account data has been posted online. For now, it appears the hackers have published a relatively small percentage of AshleyMadison user account data and are planning to publish more for each day the company stays online.

“Too bad for those men, they’re cheating dirtbags and deserve no such discretion,” the hackers continued. “Too bad for ALM, you promised secrecy but didn’t deliver. We’ve got the complete set of profiles in our abdlmatch zdjД™cie profilowe DB dumps, and we’ll release them soon if Ashley Madison stays online. And with over 37 million members, mostly from the US and Canada, a significant percentage of the population is about to have a very bad day, including many rich and powerful people.”

ALM CEO Biderman declined to discuss specifics of the company’s investigation, which he characterized as ongoing and fast-moving. But he did suggest that the incident may have been the work of someone who at least at one time had legitimate, inside access to the company’s networks – perhaps a former employee or contractor.

“We’re on the doorstep of [confirming] who we believe is the culprit, and unfortunately that may have triggered this mass publication,” Biderman said. “I’ve got their profile right in front of me, all their work credentials. It was definitely a person here that was not an employee but certainly had touched our technical services.”
