Last night, hackers made good on their promise to release data involving 37 million users of cheating site AshleyMadison.com. “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,” reports Wired. The sensitive data includes names, contact info and seven years worth of credit card and payment transactions (but not full credit card numbers). “This event is not an act of hacktivism, it is an act of criminality,” said parent company Avid Life Media in a statement. “It is an illegal action against the individual members of AshleyMadison.com, as well as any freethinking people who choose to engage in fully lawful online activities.”
