Germany’s domestic intelligence agency has warned business executives about foreign espionage operations that use romantic relationships to obtain sensitive information, following allegations involving Nvidia CEO Jensen Huang. The Federal Office for the Protection of the Constitution (BfV) issued the warning after reports linked Huang to Alice Huang, who is accused of gathering intelligence for China. According to German media reports, the agency said such operations often target prominent figures in politics and business, using romantic relationships to place them in compromising situations. The BfV warned that targets are carefully selected and that the tactics can lead individuals into either conscious or unwitting cooperation with foreign intelligence services.
