Intelligence agencies retrace alleged spy's trail across NATO and Canadian institutions

Espionage investigation tracks what Biwei Zhang accessed at NATO and agencies Canada and Europe review potential damage, security logs and links—see the latest

Western intelligence agencies are reviewing what an accused Canadian intern may have accessed during placements at NATO and several governmentrelated organizations. Belgian authorities arrested Biwei Zhang in July on espionagerelated allegations, and she remains in pretrial detention after being denied release on appeal. CBC reports that investigators in Canada and Europe are trying to reconstruct Zhang’s decadelong path through internships and jobs at organizations including Statistics Canada, the Canadian Space Agency, the European Space Agency, the World Trade Organization and NATO’s military headquarters in Belgium. The aim is to determine what information could have been exposed, whether any damage occurred and whether she acted alone. CSIS says it is coordinating a multidepartment damage assessment with federal partners. Experts quoted in the report say the review will likely focus on security logs, badge records, surveillance footage and possible links to broader networks. NATO says its critical systems were not compromised, while Belgian officials have not publicly identified who may have been behind the alleged espionage.
