While China cracks down on inter-state gambling by its own citizens, they may be using gambling firms to spy on rival nations. That’s the suggestion by an Indian security agency, who’ve tied increased gambling activity to recent frictions with their neighbor.

The Indian Times reports local police authorities think Chinese gambling firms may be using their apps to help phish information during times of friction. “There are many angles, including clandestinely accessing gamers’ personal information,” Hyderabad police told the outlet. “The possibility of gamers’ personal data being exported abroad cannot be ruled out.”

This possibility became hard to ignore after recent border skirmishes between the two nations. In June, 20 Indian troops were killed in a clash over the Himalayan border area after Chinese troops claimed they crossed the border. No bullets were fired, and the Indian troops were alleged to have been beaten to death with sticks and clubs.

Around that same time, authorities believe Chinese gambling firms became more aggressive in advertising to Indians.
