When criminals expose intimate data from an infidelity website everyone is affected.
A month ago a group called Impact Team stole the user database and transaction history from Ashley Madison, a website that arranges liaisons for married people.
Last week the group released the data online. It has names, addresses, personal details and sexual preferences of more than 30 million people.
The data isn’t easy to sift. But anyone throwing a lot of resources at the problem will be able to extract information. Journalists and others have already found the names of celebrities, politicians and business leaders. No-one who was a customer will be safe.
