Sony Pictures Entertainment’s hacking ordeal has reportedly ensnared Deloitte.

Salary information for employees of the professional services and auditing firm appears to have been leaked as part of the cyber attack, according to a report Wednesday on Fusion.

“We have seen coverage regarding what is alleged to be 9-year-old Deloitte data from a non-Deloitte system,” a spokesman for the company said. “We have not confirmed the veracity of this information at this time.”

The salary information dates back to 2005, Fusion reports. It appears that the company’s information may have been stored by a Sony employee who once worked at Deloitte.

A group calling itself Guardians of Peace claimed credits for the attack, which was launched last week and left Sony without access to business systems and email for days. Five Sony films, including unreleased titles such as “Annie,” “Still Alice” and “Mr. Turner,” were leaked as part of the attack.

In related news, Sony is denying a Re/Code report that the studio will officially name North Korea as the source of the cyber attack.

“The investigation continues into this very sophisticated cyber attack,” a Sony spokeswoman said in a statement to Variety. “The Re/Code story is not accurate.”

A source close to the studio said that no announcement will be made Wednesday about the origins of the attack, as Re/Code initially reported.

North Korea is suspected of being involved in some capacity because its government is angry about the upcoming Sony comedy “The Interview,” which depicts a television personality’s attempts to assassinate Kim Jong- un. Sony is moving forward with plans to release the film on Dec. 25 and will not alter the movie itself or its promotional materials.
