Kitchener man pleads guilty in U.S. to hacking charges: DOJ

The department said he and others involved in the “widespread computer hacking conspiracy” stole billions of “sensitive customer records” and advertised the breached data for sale on cybercrime forums. The Department of Justice did not name any of the companies involved.

According to the indictment filed in court, Moucka and his co-conspirators extorted funds paid out in cryptocurrency worth approximately $2.5 million at the time.

Companies involved in the incident included major U.S.-based telecommunications, retail and health care firms, the indictment said.

The department said the Canadian man used the data obtained through the security breach to extort — and in at least in one case “re-extort” — victims of the conspiracy.

Moucka himself obtained at least $495,000, the Department of Justice release said. It said companies that were targeted lost more than $9.5 million, a figure that does not include any losses incurred by their customers.

The department said Moucka was arrested and extradited from Canada last year following an FBI investigation that received international assistance from police in Canada, Turkey, Ukraine, Spain and Australia.

DOJ records on the case said Moucka surrendered himself for extradition in March of last year and initially pleaded not guilty to all charges.
