Artificial intelligence has changed the world of espionage. Powerful chips, cyber operations and digital surveillance now shape the contest between rival states.
Yet one of the oldest intelligence tactics remains relevant: using personal relationships to gain access to influential people.
The alleged espionage controversy surrounding Nvidia chief executive Jensen Huang has brought that tactic, commonly known as a honey trap, back into public discussion.
Huang has admitted to an affair with Chinese business executive Alice Huang. But the more serious allegation that she was recruited by China's intelligence service to gather information from him remains unproven.
The controversy has prompted Nvidia's board to launch an independent investigation. It has also raised questions about the vulnerability of senior business leaders whose decisions can carry major national and economic consequences.
When Intimacy Becomes an Intelligence Tool
A honey trap involves the use of romantic or sexual relationships to obtain information, influence decisions or create material that can later be used for blackmail.
The approach is not new. Intelligence agencies have long recognised that personal relationships can provide access that formal surveillance cannot easily achieve.
Targets may be drawn into relationships before sensitive information is requested. In other cases, intimate photographs or recordings may be used to threaten exposure and secure cooperation.
The tactic does not always involve professional seducers. Business contacts, acquaintances and people already moving within a target's social circle can also become useful sources of access.
The central objective is not necessarily romance. It is access, influence and information.
Famous Cases From the Cold War
One of the best-known names in espionage history is Mata Hari, the Dutch dancer executed by France in 1917 after being convicted of spying for Germany during the First World War.
Her story has since become part of popular spy mythology. However, historians have questioned the strength of the evidence against her and the extent of the intelligence she actually provided.
The Cold War produced other cases involving relationships and personal vulnerability.
In France, ambassador Maurice Dejean was recalled from Moscow in 1964 after an extramarital affair became a major scandal. The incident was linked to concerns about Soviet intelligence operations.
Former French president Charles de Gaulle was reported to have mocked the ambassador with the remark: "Alors Dejean, on couche?" loosely translated as, "So, Dejean, sleeping around?"
Another case involved John Vassall, a British embassy employee who was blackmailed by Soviet intelligence after compromising photographs were obtained during his time in Moscow.
The photographs exposed his homosexuality at a time when it could have carried serious personal and professional consequences. He was subsequently persuaded to pass sensitive information to the Soviet Union.
A Relationship That Led to an Abduction
A particularly striking case involved Mordechai Vanunu, an Israeli former nuclear technician who disclosed details of Israel's nuclear programme in 1986.
After the information was made public, he was approached in Europe by a woman using the name Cindy. She persuaded him to travel to Rome, where he was abducted by Israeli intelligence agents and taken to Israel.
The operation demonstrated how a personal relationship could be used to bring a target into a location where an intelligence service could act.
Another case involved French diplomat Bernard Boursicot and Chinese opera singer Shi Pei Pu. Their relationship lasted for years, while Boursicot passed sensitive information to Chinese intelligence. The case became one of the most unusual espionage scandals of the Cold War.
Not Every Operation Looks Like a Spy Film
Honey traps are often imagined as elaborate operations involving glamorous agents and secret meetings. In practice, they can be far less dramatic.
East Germany's intelligence service, the Stasi, became known for its so-called Romeo spies. Male agents were assigned to establish romantic relationships with unmarried women working in West German government departments.
The women were targeted partly because their positions could provide access to official documents and confidential information.
A CIA study later described how the shortage of eligible men after the Second World War had made some West German women more vulnerable to such approaches.
Other operations have involved business executives, journalists, wealthy individuals and people with established access to senior officials.
The common factor is the opportunity to build trust with someone who holds valuable information.
Why the Nvidia Allegations Have Raised Concern
The latest controversy has drawn attention because of the position held by Jensen Huang.
He leads Nvidia, one of the world's most important manufacturers of artificial intelligence chips. The company's technology is central to the development of advanced AI systems, making its business decisions significant to both commercial competition and national security.
Alice Huang, also known as Huang Le, was reportedly a senior executive at Megaspeed International, a Singapore-based data centre company linked to Nvidia's business network.
According to reports citing people familiar with US intelligence assessments, she was suspected of working for China's Ministry of State Security.
The allegations suggested that her relationship with Jensen Huang may have provided opportunities to gather information about Nvidia and US policy on advanced chip exports to China.
The reports also linked Megaspeed to investigations into the possible movement of restricted Nvidia chips into China. The company has previously rejected suggestions that it was involved in illegal transfers.
However, the espionage claims have not been independently established.
Huang Admits Affair as Nvidia Opens Inquiry
The controversy intensified after Huang acknowledged that he had been unfaithful to his wife, Lori Huang. In a message to Nvidia employees, he apologised for the personal harm caused by his actions.
"I was unfaithful to my wife," he wrote. "My actions hurt her and our children. There is no excuse for what I did. I am deeply sorry."
Nvidia's board subsequently announced an independent investigation into reports that its chief executive had been targeted by a foreign intelligence operation.
The company said it had no reason to believe that national security information or Nvidia secrets had been compromised. Huang has indicated that he will cooperate with the inquiry.
China has rejected the allegations. Foreign Ministry spokesman Guo Jiakun described the reports as an attempt to smear the country.
The distinction is important: the affair has been acknowledged by Huang, but the alleged intelligence operation remains under investigation.
Why Senior Executives Can Become Targets
The case has renewed questions about the personal security of business leaders whose work touches national interests.
Huang is not simply the head of a technology company. He is also an influential figure in the global debate over AI development and the export of advanced chips.
His views on allowing Nvidia products into China have attracted attention in Washington, where export controls have been used to limit Beijing's access to some advanced technologies.
That makes access to his thinking potentially valuable to foreign governments. It does not, however, establish that any confidential information was obtained through the alleged relationship.
Intelligence researchers say relationships can create risks when personal trust overlaps with professional access. The danger may involve blackmail, the disclosure of confidential information or attempts to influence decisions.
But not every close relationship with a foreign business contact is an intelligence operation. Evidence is needed before such a conclusion can be reached.
The Warning Signs of a Honey Trap
Counter-intelligence agencies have long warned officials and business leaders to be cautious about unexpected approaches from people whose interest appears unusually intense.
Some operations begin with invitations to private meetings or requests for personal contact. Others develop gradually through professional networking and social relationships.
A former French security officer recalled being approached by a woman who claimed to be a journalist seeking an interview with a senior security official.
He told AFP that she repeatedly avoided questions about her reporting work while introducing personal details and sending suggestive photographs.
Such behaviour can raise concerns, particularly when professional explanations do not match the nature of the approach. British security guidance has also warned officials to be cautious when a new contact's attention appears unusually intense or too good to be true.
The advice is straightforward: protect sensitive information, verify unexpected approaches and report suspicious contact through the appropriate security channels.
An Old Tactic in a New Technology Race
The technology used in espionage may continue to evolve. But the human weaknesses that intelligence services seek to exploit have changed far less. Attraction, loneliness, ambition and the fear of public embarrassment can all create openings for manipulation.
The allegations involving Nvidia have brought those risks into the heart of the global AI industry. They also show why senior executives can become targets when their professional relationships overlap with geopolitical interests.
For now, the facts remain under investigation. Whether the alleged relationship was part of a deliberate intelligence operation will depend on evidence that has yet to be made public.
The episode nevertheless offers a reminder: even in an age of artificial intelligence and advanced surveillance, some intelligence operations still begin with a personal connection.
