Toronto police are denying the allegations in a U.S. court document that says names and addresses of more than 500 confidential police informants were hacked by an online group led by a former U.S. navy nuclear systems administrator.

The tiny American group, known as “Team Digi7al,” successfully attacked Toronto police computers between May 23 and June 1, 2012, according to a document filed this week by the U.S. Attorney’s Office in a Tulsa, Okla., court.

The allegations have not been proven in court.

“No informants were compromised,” Toronto police spokesman Kevin Masterman said Thursday. “They didn’t breach any internal systems.”

Hackers were able to access some outdated information such as crime alerts and community bulletins, but nothing of a confidential nature, Masterman said.

His comments are at odds with the court document, which refers to a juvenile hacker known as “Member B”: “Between May 23, 2012, and June 1, 2012, TD (Team Digi7al) Member B hacked at least one TPSC (Toronto Police Service) protected computer and downloaded a large file containing over 100 tables with the following sensitive and private information: more than 3,500 email addresses; over 2,500 usernames and cleartext passwords, including administrator usernames and cleartext passwords; names, addresses, phone numbers, and email addresses of citizens who gave police tips through TPSC’s online tip system; names, addresses, phone numbers and email addresses of greater than 500 police informants; suspect descriptions; and press releases, police reports, and Tweets.”

The alleged hackers were motivated by a mixture of anti-government politics, ego and boredom, according to the court papers.

They were led by Nicholas Knight, 27, of Virginia, who once worked as a nuclear system administrator on the aircraft carrier Harry S. Truman and who went by the online names of “Inertia,” “Logic” and “Solo,” the document states.

Knight, a hacker since age 16, has since been kicked out of the U.S. Navy after he was caught trying to hack into a navy database while at sea, according to the court document.

It states that Knight “called himself a ‘nuclear black hat’ who fought for the people of the United States, not the government.”

Also charged was Illinois community college student Daniel Krueger, who studied network administration and was known online as “Thor,” “Orunu” and “Gambit.”

Knight and Krueger are due back in court on May 20. They each face a possible five-year prison term and $250,000 fine.

Three underaged members of their group from Alabama, Louisiana and Georgia were also mentioned in the court papers as “Members A, B and C.”

Knight and Krueger have each been charged with conspiring to steal identities, obstruct justice and damage a protected computer.

The men tried to hack into the computers of more than 30 organizations, including the U.S. Navy, the U.S. Department of Homeland Security, Los Alamos National Laboratory and the World Health Organization, according to the statement issued this week from the U.S. Attorney’s Office for the Northern District of Oklahoma.

According to the court document, group members used Twitter to taunt Toronto police and boast about their exploits on what they called the “lulz crusade across #Canada.”

A Twitter account still online with the group’s name shows the user fired off tweets to a Globe and Mail staffer and the CBC, boasting of their alleged hacks.

On June 3, 2012, someone tweeted: “@Torontopolice why is there nothing on your site about us hacking you? Don’t tell us your trying to sweep it under the rug into the dark. (sic)”

On June 8, 2012, the Twitter user posted: “@TorontoPolice you are trying to figure out who hacked you? It was us as we said numerous times.”
