Chip smuggling operation that sent 53,000 banned American chips to China gets busted — $12 million worth of chips funneled through South Korean company

South Korea's customs office has busted a chip smuggling operation that involved 53,000 chips worth $11.6 million, making it by value the biggest chip smuggling bust yet. This smuggling operation was so massive that an entire company known only as 'Company A' was behind it, rather than a single individual. All executives at the company have been charged by prosecutors for the crime, which was perpetrated over three years.

From August 2020 to August 2023, 'Company A' legally bought U.S.-made chips and imported them, also legally, to South Korea, according to BusinessKorea. Some of these chips were then smuggled by air to China in 144 individual trips, simply by not declaring them to customs. Although many smaller-scale smugglers have tried to bring consumer CPUs and GPUs into China in the past, this operation involved chips made to convert analog signals to digital. Because these chips could conceivably be used for weapons of mass destruction, they have been under export and import restrictions since 2020.

Of course, 'Company A' would have left a paper trail when purchasing these chips, but the company was able to keep its scheme under wraps by skimming off the top of a legitimate business. 'Company A' ordered more chips than it actually needed from official distributors of the communications processor. If every single one of these chips were being smuggled to China, it would have roused suspicions much sooner.

The smuggling operation is by far the largest ever busted in respect to value, and probably also in respect to quantity. The previous record holder was an attempt to smuggle $4 million worth of CPUs, SSDs, and other electronics from Hong Kong to China. The would-be smuggler similarly incorrectly declared his goods to customs officials, who weren't fooled and subsequently busted the plot.

A key difference with this South Korean smuggling operation compared to most others is that the goods were all successfully smuggled, and the crime wasn't discovered until months after it reportedly concluded. While the CEO and executives of 'Company A' will likely face serious consequences, the chips are presumably being used for purposes so far unknown, perhaps even inside weapons of mass destruction as the U.S. government fears.

The news comes amid an ongoing battle -- often deemed a chip war -- between the US, China, Taiwan, and others for control over the semiconductor industry, the world's most critical resource and a key component of a vast array of products, everything from PCs and data centers to cars, lightbulbs, refrigerators, and more.

    I wonder if we will start to see mandated additions of hardware to make it harder to snuggle these. Like rfid chip embedding or something custom made and hard to remove. These chips are quickly becoming the new super weapons and I worry that distinction will cause them to get regulated to heavily.

    Just hoping someone comes up with ai that doesn't resemble a graphics card soon. We need the ASIIC of the ai world to free up gpus again.

    Years ago, Intel had upgradeable CPUs. They would be crippled till they were verified by Intel after you paid an absurd premium.

    Each GPU can contain a serial number that gets encoded and sent to companies for a unique activation code internally. It would make them traceable via IP address. It would be obvious if the GPUs were used elsewhere or a large number were activated at an IP to street address and the GPUs are no longer there. You can't activate 5000 GPUs tied to you by ip address and then have them poof.

    For me, this is the most intriguing aspect of the entire story. I have difficulty imaging any sort of ADC that's not fundamentally dual-use.

    For instance, consumer audio gear has tons of ADCs, but I guess they're too low-frequency to be relevant. Then, there's the HD video capture card market which, although it's been largely HDMI, for a long time, still existed for analog signals. There are also plenty of commodity VGA -> HDMI converters that handle 1080p60, as well. Moving into even higher frequency domains, you have things like digital oscilloscopes, which I'd imagine need probably at least 8-bit precision, into the GHz range. And then, of course, data acquisition cards for scientific and perhaps medical applications.

    So, I'd love to know what sort of line has been drawn, in this area.

    Eh, GPUs are still available near list price, as far as I can tell. It's nothing like the sort of scalping situation we had during the crypto mining boom.

    If you're talking about Nvidia H100's, those aren't really GPUs. Moreover, whatever AI-oriented ASIC might replace them would still be competing for the same TSMC wafer capacity. Just be glad they use HBM and not GDDR6.

    Huh? Intel On Demand only just launched with Sapphire Rapids, less than a year ago!

    The article isn't even talking about GPUs, just so we're clear.

    You can't stop people from getting a license key to unlock their GPU and then moving it to another machine, on another network. Also, relying on network-based location services is doomed to fail, since too many people would fall through the cracks.

    Supply and demand is a more powerful force than government sanctions and laws.

    What is China doing with all these chips? Destroying them or keeping them for themselves?

    I could be wrong but I’m guessing this is more like the DSPs in high end phones or basically what they now refer to as neural processors. They’re matrix math processors optimized for lower precision data types for AI inference style work loads. It’s surely not about some audiophile ADC.

    No. Intel sold processors with disabled cores and cache. You ran their upgrade utility after paying a small fortune online, and the additional cores and cache were made available. This was when circuit City was still around. It fell flat on its face because it cost 1/2 as much as the processor for a very small boost.

    That's said, yes you most certainly can stop them. 10,000 GPUs registered to a static IP owned by "shady x corp" and then suddenly disappearing is a good clue these GPUs have been diverted. Registering via VPN would result in a fail. Don't register the GPUs, they stay crippled. I have seen similar things done already in "sensitive" items. Case in point tagins , color laser printers, and lowjack laptops There are other examples I cannot quote and additional hardware security measures that can be taken, which I also cannot quote.

    If any of these GPUs are found in a large scale import bust, then the paper trail exist to prosecute someone. There are other ways of catching them.
