Shares of Nvidia were trading down 5% early Monday morning, a sign of the huge uncertainty now hanging over the AI chip giant in the wake of the company’s disclosure Sunday that it would investigate recent reporting that CEO Jensen Huang “had been the target of a foreign intelligence effort.”

Adding to the drama, Huang acknowledged having had an affair, saying he was “deeply sorry.” The New York Times reported last month that Huang had a “close relationship” with a Chinese businesswoman who allegedly shared intelligence with Beijing authorities. We don’t know where this will lead. But given Huang’s position as one of AI’s biggest advocates, the ripples could be felt everywhere in the sector.

Meanwhile, an Australian startup has come up with a new way to fight AI-enabled cybercrimes: sending an army of AI agents to pose as gullible grandmas and unsuspecting job seekers so as to lure the bad guys.

Apate.ai is going up against a multibillion-dollar scam industry powered by thousands of workers in scam compounds, mostly in Southeast Asia. These scammers have gotten more sophisticated with the help of technology. Investigators have struggled to keep pace with ever-evolving tactics, and often only begin the chase after victims report their losses.

Apate.ai, founded in 2024, thinks it’s found a way to help tip the scales. By posing as potential victims, its army of AI agents are able to engage scammers in lengthy conversations designed partly to waste time and divert attention from real victims.
