State Media: 'CSIS's refusal to provide a briefing to CSA with Zheng in the room eventually helped to trigger an internal investigation into Zheng in 2018.
'While Zheng was working at the agency, CSA technicians noted the presence of unauthorized software by a foreign company, say the recently filed court documents.
'At least one secure file transfer service and a messaging application were identified on the computer, violating internal policy, the documents say.
'Zheng was told of the CSA internal review on Dec. 17, 2018 and went on sick leave a few days later.
'The space agency went to the RCMP in September 2019 to report that it suspected Zheng had transmitted secret information to a third party.'
