They Used a Hairdryer to Move Serial Numbers Off $2.5 Billion Worth of Nvidia Chips

This story has a lot of extraordinary details. The one that stopped people scrolling on Thursday was the hairdryer.

According to the Department of Justice indictment unsealed in Manhattan federal court on March 19, the conspirators maintained a warehouse in Southeast Asia filled with thousands of dummy servers. These were not metaphorical dummies. They were actual physical replicas of Supermicro’s real products, empty shells assembled specifically to fool auditors into thinking the high-value AI servers packed with banned Nvidia chips were sitting right there waiting for their legitimate Southeast Asian buyer.

To make the deception hold up under inspection, someone needed to make sure the serial number labels on the real servers matched records for the fake ones. The solution, according to court documents and widely circulated in coverage from Tom’s Hardware, was a hairdryer. Heat the serial number labels off the real servers. Transfer them to the dummy shells. Photograph the warehouse full of dummy servers with the right serial numbers on them. Send the documentation to Supermicro’s compliance team as evidence the servers had arrived safely at their legitimate destination. Meanwhile, the real servers, packed with Nvidia H200 and B200 chips banned from export to China, were on their way to Chinese buyers in unmarked boxes.

The scheme ran for two years. It moved $2.5 billion worth of servers. The co-founder of one of Silicon Valley’s most prominent AI hardware companies allegedly had a direct hand in running it. He is now under federal arrest facing up to 20 years in prison.

Who Is Wally Liaw and Why His Arrest Shocked Silicon Valley

Yih-Shyan “Wally” Liaw, 71, cofounded Super Micro Computer in 1993 alongside CEO Charles Liang. For three decades he was an integral part of building Supermicro from a San Jose startup into one of the most important server manufacturers in the AI infrastructure boom. By the time of his arrest he held nearly half a billion dollars worth of Supermicro shares and served as both senior vice president of business development and a member of the company’s board of directors.

Supermicro’s stock had been one of the defining winners of the AI hardware surge. The company supplies servers to hyperscalers and AI labs, and because Nvidia’s GPUs go into those servers, Supermicro’s fortune tracks closely with the demand for AI compute infrastructure. Before the arrest news dropped, the stock had been recovering from an earlier accounting scandal that had nearly gotten it delisted from Nasdaq. Liaw was not some peripheral figure. He was one of the people who built the company and had spent the last several years helping it ride the AI wave.

The two co-conspirators charged alongside him are Ruei-Tsang “Steven” Chang, 53, Supermicro’s Taiwan general manager, who is currently a fugitive, and Ting-Wei “Willy” Sun, 44, a third-party broker and fixer who worked with the other two and is being held pending a detention hearing. Liaw was arrested in California and released on bail. Supermicro placed Liaw and Chang on administrative leave immediately and terminated its relationship with Sun. The company said it was cooperating fully with the investigation and noted that neither it nor CEO Charles Liang nor co-founder Sara Liu were named in the indictment.

The Full Scheme: Fake Companies, Dummy Servers, and $510 Million in Three Weeks

The DOJ’s description of how the operation worked is detailed enough that the full picture is worth explaining, because the level of coordination and premeditation is significant.

The pipeline the indictment describes worked in stages. Liaw and Chang allegedly identified Chinese buyers who wanted servers containing Nvidia’s restricted H200 and B200 GPU chips. Those chips are subject to US export controls that prohibit their sale to China without a license because of their potential military and strategic applications. To get around the controls, the conspirators needed an intermediary who could legitimately buy the servers from Supermicro.

They found one in an unnamed Southeast Asian company whose executives were allegedly brought into the conspiracy. That company would place purchase orders with Supermicro as though the servers were destined for its own operations. Supermicro would assemble the servers in the US, ship them to its Taiwan facilities, and deliver them to the Southeast Asian company. So far, this looks like a normal sale to a legitimate customer in a country where the export is permitted.

Then the scheme diverged from legitimate commerce. The Southeast Asian company, working with Liaw, Chang, and Sun, would arrange to have the servers repackaged. The original Supermicro packaging, with its identifying labels and serial numbers, would come off. The servers would go into unmarked boxes. A logistics company would take the unmarked boxes to their true destination in China. Throughout this process, fake documentation was generated and sent to Supermicro’s compliance team to make the servers appear to still be sitting legitimately in the Southeast Asian warehouse.

The operation grew more aggressive over time. According to the DOJ, during a three-week period from late April to mid-May 2025, approximately $510 million worth of servers assembled in the US were shipped to China under this arrangement. Half a billion dollars in banned AI hardware moved to China in three weeks while compliance teams were looking at photos of dummy servers with hairdryer-transferred serial numbers.

The Sobbing Emojis That Made the Indictment

Of all the details in the indictment, the one that captures the psychology of the operation most clearly is a single message exchange from August 2025. One of the brokers involved in the scheme sent Liaw a link to a DOJ press release about other people who had been arrested for AI chip smuggling. Liaw replied with a string of sobbing-face emojis.

He then kept working with Chang and Sun.

That detail is in the indictment. The sobbing emojis suggest Liaw understood exactly what he was doing was illegal and understood the consequences when other people got caught doing it. The decision to continue anyway, while other people were being prosecuted for the same conduct, is what the DOJ is now citing as evidence of willfulness. It is also what makes the detail so striking. Reading about other people’s arrests and responding with sadness about their consequences, and then continuing the same scheme, is the kind of behavior that makes federal prosecutors’ jobs considerably easier in court.

The indictment also notes that as pressure increased in late 2024, when Supermicro’s compliance team started an internal audit and the company was dealing with separate accounting issues that had attracted DOJ scrutiny, the defendants allegedly worked harder to hide what they were doing rather than stopping. The timing of the scheme’s most aggressive phase, the $510 million in three weeks in spring 2025, came after Supermicro had already begun the compliance audit. The defendants were allegedly accelerating as the risk increased.

Why Nvidia’s H200 and B200 Chips Are Worth Smuggling

The specific chips at the center of this case are Nvidia’s H200 and B200 GPU models, both of which are subject to US export controls that prohibit their sale to China without a government license. Understanding why these specific chips are restricted helps explain why the smuggling operation was economically compelling enough to attempt.

The H200 is the successor to the H100, which became the most strategically important piece of computing hardware in the world during the early years of the AI boom. Training large language models at scale requires enormous clusters of these chips. The H200 delivers significantly higher memory bandwidth than the H100, which is critical for inference workloads that move enormous amounts of data between the model’s parameters and the processing units. For AI labs trying to serve large volumes of inference requests efficiently, H200 availability is a meaningful constraint on what they can do.

The B200 is the flagship of Nvidia’s Blackwell architecture generation, offering even higher performance for both training and inference. A system of B200s is the most capable commercially available AI compute infrastructure that exists. China’s AI labs, which cannot legally buy either chip without an export license, face a fundamental constraint on their ability to train and deploy competitive AI models compared to their American counterparts. That constraint creates strong economic incentive to acquire the chips through any available channel, legal or otherwise.

The Financial Times reported in July 2025 that China had managed to obtain approximately $1 billion worth of advanced AI processors in the three months after Trump tightened export controls. The Supermicro scheme, if the timeline in the indictment is accurate, was a significant component of that flow. The $510 million moved in three weeks during spring 2025 represents roughly half of the entire three-month estimate of restricted chip flows, though the precise overlap with the FT’s reporting period is not exact.

The Stock Crashed 33%. Then It Got Worse.

Supermicro shares fell roughly 12 percent in after-hours trading on Thursday evening when the arrest news first broke. By Friday pre-market trading, the stock was down more than 25 percent. By the time markets closed, Seeking Alpha and CNBC were reporting a total decline of approximately 33 percent from the pre-news price.

Wally Liaw personally held nearly half a billion dollars worth of Supermicro shares at the time of his arrest. A 33 percent decline means he lost approximately $165 million in paper wealth in roughly 24 hours, in addition to facing federal criminal charges. For someone who spent three decades building a company, the financial and reputational consequences of what he is alleged to have done are comprehensive in a way that is difficult to fully quantify.

The stock decline reflects more than just investor reaction to the arrest. Supermicro was already carrying reputational weight from the accounting issues that had caused auditor EY to resign in October 2024 and had put the company at risk of Nasdaq delisting. The company had spent much of 2025 trying to restore investor confidence in its governance. The arrest of a co-founder on federal smuggling charges, while the company is simultaneously under a DOJ investigation related to accounting, is the kind of news that does not help that effort. Nvidia’s statement was pointed: “Unlawful diversion of controlled U.S. computers to China is a losing proposition across the board. NVIDIA does not provide any service or support for such systems.”

This Is Not Supermicro’s First Export Control Problem

Fortune’s deeper investigation into Supermicro’s history, published hours after the arrest, reveals a pattern worth examining. In 2006, twenty years before this indictment, Supermicro pleaded guilty in federal court to illegally exporting computer equipment to Iran and paid a $150,000 fine to the DOJ. Separately it paid $125,400 to settle parallel charges from the Commerce Department’s Bureau of Industry and Security. It also paid $179,327 to the Treasury Department’s Office of Foreign Assets Control for violations of the Iranian Transactions Regulation, violations that OFAC noted Supermicro did not voluntarily disclose.

The two cases, separated by two decades and vastly different in financial scale, share what Fortune described as a similar alleged pattern: find a neighboring country where it is legal to sell to, hide the real buyer, and ship the restricted technology to the illegal market. The Iran case used the same transhipment model at a fraction of the scale. The 2024 to 2025 operation allegedly replicated the approach with Nvidia’s most advanced AI chips at a scale 16,000 times larger in dollar terms.

Whether the 2006 guilty plea and the current indictment reflect an institutional culture problem at Supermicro or represent the conduct of specific individuals acting contrary to company policy is something the DOJ investigation will likely address. Supermicro’s public statement emphasized its “robust compliance program” and said the alleged conduct contravenes company policies. The 2006 case was resolved as a corporate guilty plea. The current indictment names individuals, not the company.

China Got $1 Billion in Banned Chips in Three Months Last Year. This Is Why.

The Supermicro scheme is the most detailed public account of how restricted Nvidia chips have been reaching China despite export controls, but it is not an isolated case. The broader picture of chip flow to China despite legal prohibitions involves multiple channels and a systematic commercial infrastructure that has developed specifically to work around export restrictions.

The transhipment model used in this case, routing hardware through a Southeast Asian intermediary country where the export is legal before repackaging and forwarding it to China, is the dominant method identified in enforcement actions and intelligence reporting. Singapore, Malaysia, Thailand, and other countries in the region have all appeared in enforcement contexts as transhipment points. The FT’s $1 billion estimate for the three months after the April 2025 export control tightening suggests that the Supermicro operation was one of multiple simultaneous channels rather than the sole mechanism.

Chinese companies have been paying significant premiums for restricted chips on secondary markets. Reports from 2025 documented Chinese buyers willing to pay two to three times the official retail price for H100 and H200 chips obtained through informal channels. At those premiums, the economics of a transhipment operation that requires building dummy server infrastructure and bribing logistics companies become compelling for anyone willing to accept the legal risk. The Supermicro scheme allegedly generated $2.5 billion in sales over two years, even accounting for the overhead of maintaining the deception.

Nvidia has consistently maintained that it strictly complies with export controls and does not provide service or support for systems it knows have been illegally diverted. That position is legally accurate. The enforcement challenge is that Nvidia sells to legitimate customers who then illegally resell or route the hardware. Detecting that diversion before it happens requires either intelligence about the end buyer’s intentions or post-sale monitoring of where the hardware actually ends up, both of which are operationally difficult at the volume Nvidia ships.

What Happens Next: Fugitives, Federal Charges, and the Chip War

Liaw was released on bail after his California arrest and has not yet entered a plea. Sun is being held pending a detention hearing. Chang, the Taiwan-based Supermicro sales manager, remains a fugitive. The DOJ has not publicly described extradition proceedings related to Chang, though the US and Taiwan have a functional law enforcement cooperation relationship despite the absence of a formal extradition treaty.

The charges against all three carry maximum sentences of 20 years per count. Federal prosecutors in the Southern District of New York, which handles many of the most significant financial and national security cases in the US, unsealed the indictment. The scale of the alleged conduct and the involvement of a co-founder of a major publicly traded company would suggest prosecutors intend to pursue the case aggressively.

For Supermicro the institutional consequences are less clear. The company is not named in the indictment and has cooperated with investigators. Its response, placing the accused employees on leave and terminating the contractor relationship, is the standard corporate posture in situations where individuals are charged without the company itself being named. Whether the DOJ investigation that was already open on accounting grounds expands to encompass export control violations at the institutional level is a question the company’s legal team is almost certainly focused on.

The broader chip war context matters for understanding why this case was prosecuted at the level it was. The Biden and Trump administrations both treated export controls on advanced AI chips as a strategic national security tool. The enforcement mechanism for those controls is exactly what is on display here: criminal prosecution of individuals who circumvent them, with sentences that carry real prison time rather than just fines. The DOJ’s description of this as the “highest-profile crackdown” on AI chip smuggling is a signal about enforcement priorities, not just a description of this case.

The Bigger Picture

The Supermicro case is the most vivid illustration yet of how valuable the chips at the center of the AI race have become, valuable enough that a 71-year-old co-founder of a publicly traded company worth billions allegedly built an elaborate two-year operation to move them illegally across borders. The dummy servers, the hairdryer, the fake paperwork, the sobbing emojis followed by business as usual: these details describe someone who understood the risk and judged the rewards worth taking it.

Whether the calculation was correct is now in the hands of a federal court. What the case demonstrates regardless of outcome is that export controls on advanced semiconductors create enormous financial incentives for circumvention, that transhipment through third countries is the dominant method for doing so, and that detection depends on specific intelligence about end-buyer intentions rather than routine compliance processes. Supermicro’s compliance team was being actively deceived with physical dummy servers. Normal compliance procedures, which rely on documentation rather than physical verification of where hardware actually goes, were specifically what the operation was designed to defeat.

The chip war between the US and China is being fought at multiple levels simultaneously: diplomatic, regulatory, and now criminal. The Supermicro indictment is the criminal enforcement level becoming visible in a way that it rarely does when it involves individual actors. Most enforcement actions at this scale stay quiet until sentencing. An unsealed indictment with a co-founder of a major AI hardware company, conspiracy charges, a fugitive, and a hairdryer used to move serial numbers is not the kind of case that stays quiet.

What do you think: are export controls on AI chips actually working, or are cases like this evidence that the restrictions are being systematically routed around faster than enforcement can keep up? Drop your take in the comments. The gap between what the policy is supposed to accomplish and what the enforcement data suggests is actually happening is the most important question in the AI chip war right now.
