“They are outraged that AshleyMadison.com failed to protect its users’ information”, the firms said in their statement.

The hack of the Ashley Madison site was first disclosed in July, with the attackers, who identified themselves as “The Impact Team“, threatening to dump the database, which is what occurred on August 19.

Two people associated with the Ashely Madison hack have committed suicide, acting staff superintendent Bryce Evans of the Toronto police revealed at a press conference on Monday. Also, several users have become victims of blackmail.

Toronto police, alongside the Ontario Provincial Police, the RCMP, FBI and U.S. Homeland Security, are probing the hack, which saw the personal information of more than 30 million site users released last week.

The San Antonio Police Department confirmed the death but would not comment on whether it was linked to the leak.

They say the website and its owner Avid Life Media didn’t do enough to keep their identities a secret.

Last week Avid Media was sued domestically in Canada in a class action lawsuit that seeks damages of more than $760 million.

“This hack is one of the largest data breaches in the world”, he said. At the time, it appeared that the Impact Team was equally perturbed with Ashley Madison’s $19 fee that purports to erase all details about a customer, which the hacking group claimed was misleading, and the fact that the site encourages extramarital affairs.

Mr Evans addressed the hackers directly, saying their actions are “illegal and will not be tolerated”. Incidents of data breaches have increased over the past few months.

This message was accompanied by music — AC/DC’s Thunderstruck, said Evans.

According to Menard, the hack has already resulted in a number of “spin-offs of crimes and further victimisation”.

Spokespersons of Avid Life Media could not be reached for a comment on demand. Hackers need to establish the fact that they have a real person’s information with a legitimate email account, and ultimately, a password, in order to steal valuable information like credit card or bank account numbers.

In the Canada lawsuit, Eliot Shore, described as a disabled widower in Ottawa, has filed a national class proceeding on behalf of all Canadians who subscribed to Ashley Madison and whose personal information was disclosed to the public.
