History
SINA came to prominence in March 2023 when it was divulged in a court warrant for the arrest of the Austrian intelligence officer Egisto Ott, who has a relationship with Wirecard fraudster Jan Marsalek, that a SINA laptop was handed to the Russian secret services,[4][5][6][7][8][9][10][11] specifically the Lubyanka Building office of the FSB.[3]
The Austrian authorities report that Ott received €20,000 for the laptop from Marsalek.[12]
