The recent data breach that exposed private information about users of the marital affair site Ashley Madison has apparently claimed another victim. The Wall Street Journal reports that Noel Biderman, CEO of Ashley Madison parent company Avid Life Media, has resigned his post.

The company announced today that Biderman had left the firm by mutual agreement.

The move comes as authorities in the U.S. and Canada are investigating the hacking attack, along with alleged extortion attempts related to the breach. A hacker group calling itself the Impact Team has claimed responsibility for the attack.

In a statement, Avid Life Media said Biderman’s exit “is in the best interest of the company and allows us to continue to provide support to our members and dedicated employees.”

“Toronto police have said they are investigating two suicides with potential links to the leaked data,” the WSJ report notes. “They also said this week that they had confirmed cases of extortion of Ashley Madison clients, in which the clients were threatened with exposure unless they paid 300 Canadian dollars (US $227). The U.S. Federal Bureau of Investigation and the Department of Homeland Security are assisting Toronto police.”

Activity on the Ashley Madison website may be more about fantasy than about actual affairs. As we reported recently, an analysis of data on the site came to the conclusion that many of the women listed on the cheating site were fake accounts.
