Today's briefing:

  • Nvidia's Jensen Huang admits affair with suspected Chinese intelligence asset.

  • Hoax bomb threats divert flights across at least 16 European countries.

  • Houthi missile debris blows out windows at Riyadh's Aramco Tower.

Most of us would like to think that if a government agency learned our principal was being targeted, someone would pick up the phone. It’s a reasonable expectation, especially when the principal runs a company whose technology matters to national security. But the agency may have its own reasons for keeping what it knows to itself.

Nvidia said it expected the US government to tell it about any threat. According to The New York Times, US intelligence knew a woman it was monitoring had grown close to Jensen Huang. She was a customer executive he knew through work, and officials reportedly believe Chinese intelligence recruited her to target him. Huang received no defensive briefing.

This week, On the Circuit, we look at what that silence meant for Nvidia and what the people around a principal can reasonably expect to know.

TOP STORY

Nvidia's CEO Was Never Warned About China

Newsprint collage headlined Watched for a Year: binoculars, a calendar with all twelve months crossed out in red, and an office door marked CEO, with the label No Warning Given.

On Sunday, November 8, Nvidia chief executive Jensen Huang told staff he had been "unfaithful" to his wife of 41 years, admitting a relationship with Alice Huang, a Megaspeed executive whom US officials believe was working for Beijing. Nvidia's board, every member except Huang himself, has opened an independent inquiry with outside counsel. It says it has no reason to believe national security or company secrets were compromised, and Huang remains in charge, Al Jazeera reported.

The question now is what the US government knew, and when. The New York Times reported on October 29 that US intelligence had placed Alice Huang under surveillance over suspected chip smuggling, and that her closeness to Jensen Huang showed up in her intercepted communications. President Trump was briefed on the findings roughly a year earlier and did not act, according to the Times. Huang was never given a defensive briefing, the warning counterintelligence agencies sometimes give Americans who are being targeted by a foreign service. Telling him could have alerted her that she was being watched.

On November 6, the Times and the Financial Times reported that China's top intelligence agency had recruited Alice Huang to target him, with a US government memo describing a romantic relationship. She was reportedly tasked with gathering information and with pushing for Nvidia's advanced chips to be sold into China. It is not clear whether she was recruited before or after their business dealings began.

Her access came through ordinary industry channels. She was photographed beside Huang at an informal gathering of AI executives in Taipei during the Computex trade show in June 2024, Megaspeed went on to buy billions of dollars of Nvidia equipment, and in May 2025 Taiwanese television filmed her standing behind him after a business dinner. When the first report broke, Nvidia said Huang meets thousands of customer executives a year and that it expected the US government to tell it about any threat.

Nvidia reports earnings on November 17. The next day, three House committee chairs want Huang in a closed-door briefing on his dealings with Alice Huang and on Nvidia's safeguards against foreign espionage. No charges have been reported, no public evidence shows Huang passed sensitive information to anyone, and China calls the reporting groundless smears.

Our Take

The photographs show why this would have been hard to spot. Alice Huang was beside Nvidia’s CEO at an industry gathering in 2024 and behind him after a business dinner in 2025. She was an executive at a customer that bought Nvidia equipment. Seeing her there would have told you very little about why US intelligence was watching her.

It’s still unclear when Chinese intelligence reportedly recruited her, so we can’t say the commercial relationship was set up for that purpose. What the reporting does show is that a genuine business relationship gave her repeated access, and that Huang was never briefed on what US intelligence had learned.

Nvidia’s point that its CEO meets thousands of customer executives is fair. It also explains why the case matters. The business contact who keeps turning up has a reason to be there. That reason can remain perfectly valid even as the relationship changes in ways the company can no longer see.

Sound even smarter:

  • Intelligence authorities in the US, Singapore and Taiwan all had reason to believe Alice Huang might be a Chinese spy, the Wall Street Journal reported on October 31, though Singapore said it had not investigated her over intelligence ties.

  • Yale's Jeffrey Sonnenfeld put Huang's chances of staying on as CEO at "about a 50-50" and called the tech industry's security practices "way too lax" next to defense contractors, TechCrunch reported on November 8.

MEANWHILE
Newsprint collage headlined Hoax Threats. Real Debris.: an airliner in a red target ring with a fighter escort, a redacted email reading bomb, and a damaged office tower, with sixteen countries in red and the label Flights Hit by Bomb Hoaxes.

Hoax Bomb Threats Hit Flights Across Europe

Between Monday, November 2, and Friday, November 6, emailed and phoned bomb threats forced flights across Europe to divert, land early or be searched. On Thursday alone, departures from at least 16 countries were affected, including the UK, Ireland, Spain and Denmark, and Eurocontrol counted 14 threatened flights among roughly 26,300 in its network. Hungary scrambled fighter jets three times on Friday to escort passenger planes, and Madrid received three emailed threats in 20 minutes covering Air Europa and Iberia flights, Al Jazeera reported.

No device has been found and no one has been hurt. Ireland's national broadcaster RTÉ was evacuated after a threat and Sky in the UK received one, the Associated Press reported. No government or group has been identified as responsible. One email to Rome airport came from a group calling itself anti-feminist, and Moscow denies any involvement.

Houthi Missile Debris Hits Riyadh's Financial District

Saudi air defenses intercepted missiles fired at Riyadh early on Sunday, November 8, and falling debris blew out windows across several floors of the Aramco Tower in the King Abdullah Financial District. No one was hurt. The Houthis also claimed strikes on Riyadh's main airport and an Aramco facility at Abqaiq, which Saudi authorities have not confirmed. The UN says more than 1,600 people have been killed since a truce collapsed in July, Al Jazeera reported.

On November 7, US missions across the region issued matching alerts citing "Iranian efforts to target U.S. government officials in the region," and warned that Iran-aligned groups may target US businesses worldwide. Non-emergency US staff have been under orders to leave Saudi Arabia since October 23, and Americans have been detained for photographing airports and impact sites.

🇨🇴 Colombia. Explosive-laden drones hit an army base in Santa Rosa del Sur, northern Colombia, on November 7, killing three soldiers and wounding at least 16. No group has claimed the attack.

🇵🇱 Poland. Prosecutors are investigating a terrorist offense after a gunman with far-right views killed six people, including a Briton and an Austrian, in Krakow's Main Market Square on November 7.

🇵🇹 Portugal. Police cleared housing protest camps in Lisbon's Rossio Square and Porto's Dom João Square for a second weekend on November 1. The US Embassy says to avoid both squares.

🇭🇹 Haiti. The US Embassy reported heavy gunfire near the embassy in Tabarre on November 7 during ongoing security operations and told Americans to avoid the area.

EXTRA INSIGHT

VETTING. From November 27, US gun dealers and manufacturers can run free FBI background checks on employees and contractors who handle firearms, ammunition or unfinished gun parts, the Justice Department said. Each check needs the worker's written consent and can usually be run once a year. Employers see only a pass, pending or fail result, never the record itself, and anyone who fails can appeal.

CRISIS COMMUNICATIONS. Hackers pushed fake radiation and chemical alerts through Ukraine's Air Alert app, used by 6.6 million people, late on November 1. About two hours later, Russia's emergency ministry app told users in 33 regions that nuclear warheads had been launched. Ukraine declared its alerts false within 15 minutes, and Russia said its sirens, text messages and broadcasts were unaffected.

  • Ronny Yordrix Guanipa Chrinos was arrested in a stolen car near the White House with three guns, and DHS says he told officers he planned to kill President Trump.

  • The FBI and CISA warned that attackers are taking over exposed refrigeration controllers after hacks hit hundreds of French supermarkets and three facilities storing blood.

  • Three men were charged in New York over a $129 million scheme that used AI to imitate company CEOs and lawyers and trick staff into wiring money.

NEW RESOURCE FOR PREMIUM SUBSCRIBERS

The 2027 Threat Outlook

Newsprint collage: a protection officer walks an executive from his front door to a waiting SUV, while a red dashed route links an office tower, a hotel, a crowded venue and the car, surrounded by a planning diary, a phone, a drone and a street map

What would you actually change about the detail after reading a threat outlook? For one team, it might be taking another look at what’s publicly available about the principal’s home. For another, it might be agreeing how staff verify an urgent instruction over the phone or what the team does when a drone appears. Those are different decisions, with different costs and different people responsible for making them happen.

This week’s Premium briefing, The 2027 Threat Outlook, takes seven shifts affecting the security industry and works through what they mean for a protection team. It brings together residential exposure, state-directed activity, lone attackers, drones, cloned voices and changes to venue and travel risk. You get a worksheet to judge which shifts matter to your principal and a first-quarter plan to put the most pressing ones into the work schedule. It’s designed to help you go into the next planning meeting with something more useful than a list of threats.

It would be reassuring to think someone would tell us if they knew our principal was being targeted. They might. They might also be protecting an investigation, or they may never know enough to make the call. We still have the part of the job that was ours to begin with: understanding who has access to the principal and noticing when that access changes. A warning from outside can help us do that work. It’s a poor place to start it.

See you next week,
