Austria faces its biggest espionage scandal in decades as the arrest of a former intelligence officer brings to light evidence of extensive Russian infiltration, lax official oversight and behavior worthy of a spy novel.

BERLIN – German media report that a fugitive former top executive of payment company Wirecard was an informant for the Austrian spy agency BVT. Jan Marsalek, the former chief operating officer of Wirecard, faces allegations of fraud and other charges in connection with the company's sudden bankruptcy earlier this year. The Sueddeutsche Zeitung daily reported Friday that German federal prosecutors have evidence Marsalek was a source for the BVT agency. German lawmaker Patrick Sensburg, who sits on the parliamentary intelligence oversight committee, told business daily Handelsblatt that Marsalek may have worked for several spy agencies simultaneously. Former Wirecard CEO Markus Braun has been arrested, along with the company's former chief financial officer and former head of accounting.
