China accuses Nvidia of backdooring its H20 GPUs

Welcome to Computing's weekly roundup of tech news in Asia. This time we look at why China is suspicious of a lifting of export restrictions on some US AI chips, and a rare glimpse into the activity of North Korea’s hackers.

For a long time Chinese AI developers have been desperate for GPUs and accelerators made by the likes of Nvidia and AMD, resorting to elaborate smuggling schemes to import them in the face of sanctions. But with the unexpected reversal of export restrictions on some chips, including Nvidia’s lower-spec H20 GPU which was originally developed for the Chinese market then sanctioned in April, the Chinese government apparently smells a rat. Nvidia executives have been called in and asked for guarantees that there are no back doors built into the H20 that would enable American snooping. Of course, it could be a tit-for-tat move by China, whose technologies are regularly banned in the west on security grounds, or it might be designed to buy time for its domestic players. The government is making concerted efforts to boost its own silicon industry, which most analysts believe is still some way behind the US in terms of its premium AI chips. This take is supported by news that DeepSeek, which developed its groundbreaking R1 LLM mainly using US-made GPUs is delaying its successor because Huawei’s premium Ascend chips aren’t up to snuff.

On the Korean peninsula, an established North Korean cyberespionage gang seems to be changing tactics, launching ransomware attacks in its southern neighbour. Meanwhile, two hackers claim to have breached a North Korean hacking group, finding evidence of attacks on South Korean government networks and companies, together with hacking tools and passwords.
