Nvidia 'Honey Trap' Scalarm Puts South Korea's Chip Industry on Espionage Alert

Samsung Electronics and SK hynix together hold more than 80 percent of the global high-bandwidth memory market, and former South Korean intelligence officials now warn that both companies — and their chairmen — are prime targets for the kind of Chinese espionage operation allegedly carried out against Nvidia CEO Jensen Huang.

The trigger is a spy scandal unfolding in the United States. U.S. intelligence officials say Alice Huang, who worked as a business executive at Singapore-based data center firm Megaspeed in 2023, collected intelligence and passed it to China. She is linked romantically to Jensen Huang. The allegations have become a significant national security concern for Washington, erupting amid an intensifying race between the United States and China for global leadership in artificial intelligence.

For South Korea, the case has served as a wake-up call, according to two former officials of the National Intelligence Service (NIS) interviewed by The Korea Times. Their core argument: Seoul supplies the components that power global AI computing, and it has simultaneously dismantled the institutions designed to protect them.

Why does the Nvidia case matter for Korean chipmakers?

Jensen Huang has met repeatedly with Samsung Electronics Chairman Lee Jae-yong and SK hynix Chairman Chey Tae-won, in South Korea and in the United States, under what has been dubbed the "AI buddy alliance." Those meetings sit at the center of the AI supply chain: Nvidia designs the dominant AI accelerators, and Samsung and SK hynix supply the high-bandwidth memory those chips depend on.

Yoo Seong-ok, a retired intelligence official who served as president of the Institute for National Security Strategy during his NIS career, said the alleged operation against Huang could easily be replicated against Korean targets.

"Chinese [or] North Korean spies — or both — could have used, or may still be using, a similar honey trap to the one allegedly used against Nvidia CEO Huang to gather confidential information and pass it on to their intelligence agencies," Yoo told The Korea Times.

He raised the possibility that information about Samsung, SK hynix and their technologies may already have reached Chinese rivals, given Nvidia's close business ties with the two Korean chipmakers.

"According to media reports, the Nvidia CEO and Alice Huang are said to have been intimate. He could have unconsciously shared details of his meetings with Korean business leaders when talking to the woman. Who knows?" Yoo said.

The stakes are structural, not incidental. Samsung Electronics and SK hynix together control more than 80 percent of the global HBM market. That concentration makes the two companies — and their top executives — strategic objectives for any foreign intelligence service seeking an inside track on the AI industry's most constrained component.

How do foreign agencies actually operate?

Jang Seok-kwang, another former NIS official, said the Nvidia scandal carries broader implications for South Korea's intelligence community because foreign agencies, especially China's, do not rely solely on trained intelligence officers. They mobilize people from all walks of life — students, journalists and businesspeople — to gather intelligence.

Alice Huang's profile fits that pattern, according to the source material: a business executive at a Singapore-based data center firm, embedded in the commercial layer of the AI industry rather than in any government apparatus.

The result, in Jang's assessment, is a threat surface that extends well beyond semiconductors. He warned that other strategic sectors, particularly the defense industry, are increasingly becoming targets of foreign espionage, and he stressed that South Korea must urgently strengthen its counterintelligence capabilities to protect strategic technologies, industrial assets and national security.

"Countries such as China, Russia and North Korea have stepped up espionage operations to obtain critical technologies and intelligence. Given this situation, what South Korea has done makes little sense," Jang said.

What has South Korea done to its counterintelligence agencies?

South Korea has moved in the opposite direction from its peers, and the former officials pointed to two specific institutional rollbacks.

First, in January 2024, the NIS lost its authority to detect and investigate espionage cases. That authority was transferred to the police.

"Since then, not a single North Korean spy has been apprehended. This suggests that the country is doing virtually nothing about counterintelligence," Yoo said.

Second, in August, the Defense Counterintelligence Command was disbanded — more than a year after its involvement in former President Yoon Suk Yeol's December 3, 2024, martial law declaration. The unit's entanglement in the martial law episode preceded its dissolution.

The timing is the point. Both changes stripped or weakened specialized espionage-detection capacity at precisely the moment, according to the former officials, when adversaries were scaling up technology-focused intelligence operations.

How are other countries responding?

The global trend runs against Seoul's. Jang noted that countries around the world have intensified intelligence gathering and analysis activities to cope with the changing security environment, and the source details two concrete examples from allied democracies.

The European Commission is considering establishing an intelligence body under President Ursula von der Leyen to respond to technological and geopolitical challenges in the AI era.

Japan has undertaken a national security and intelligence overhaul since Prime Minister Sanae Takaichi took office, and has established a National Intelligence Council to oversee its intelligence strategy.

Against those moves — a potential EU intelligence service and a Japanese national intelligence council — South Korea presents the comparison case: a country with more than 80 percent of a critical AI component market, and no dedicated counterintelligence command.

What happens next?

The former officials' warnings frame the forward agenda. Yoo's claim that no North Korean spy has been apprehended since the January 2024 transfer of espionage authority to the police sets a measurable standard by which the government's current approach can be judged. Jang's identification of the defense industry as a growing espionage target, alongside semiconductors, defines the scope of what he argues must be protected.

Both men converge on the same demand: South Korea must rebuild counterintelligence capacity before, not after, an operation of the kind allegedly run against Jensen Huang reaches Samsung's or SK hynix's executive suites.
