Microsoft on Tuesday said Chinese hacking groups were part of the recent attacks on its SharePoint collaboration software.

As early as July 7, the Chinese nation-state actors it calls Linen Typhoon and Violet Typhoon have been trying to exploit the vulnerability, as has a China-based actor called Storm-2603, Microsoft said in a Tuesday blog post.

On Monday, Charles Carmakal, technology chief of the Google-owned Mandiant cybersecurity consulting group, said in a LinkedIn post that “we assess that at least one of the actors responsible for the early exploitation is a China-nexus threat actor.”

On Sunday, the U.S. Cybersecurity and Infrastructure Security Agency said it was “aware of active exploitation” of the vulnerability, and Microsoft rolled out patches for two versions of its on-premises SharePoint releases. The software company issued a fix for a third version on Monday.

SharePoint is a key component of Microsoft’s widely used Office productivity software, enabling many people inside organizations to access internal files.

Last year, Microsoft CEO Satya Nadella made cybersecurity a top priority after a U.S. government report criticized the company’s handling of China’s breach of U.S. government officials’ email accounts.

Last week, the company said it would stop relying on engineers based in China to support the Pentagon’s use of cloud services, after a media report suggested that the architecture could have led to China-sponsored attacks against the U.S. defense arm.

In 2021, attackers affiliated with the Chinese nation-state group known as Hafnium targeted a different piece of Office software, Exchange Server, which provides mail and calendar services.

Elon Musk‘s flagship Tesla Diner opened Monday in Hollywood, California, and the CEO is already eyeing expansion

“If our retro-futuristic diner turns out well, which I think it will, @Tesla will establish these in major cities around the world, as well as Supercharger sites on long distance routes,” Musk wrote on X..

He later replied to a user requesting a location at the Starbase city in Texas, which is home to Musk’s SpaceX: “Ok.”

The Tesla Diner has 80 charging stations, two giant megascreens and classic American diner food. It is open 24 hours a day, seven days a week.

Diners can watch movies on two of the 66-foot screens or in their vehicle using the Tesla Diner app. The location features all things Tesla, with merchandise and an Optimus robot serving popcorn.

The China-U.S. trade war in the first Donald Trump administration saw Apple CEO Tim Cook go on a charm offensive with the president while maintaining strong relations with Beijing.  

Apple avoided U.S. tariffs and continued to grow in China, while Cook earned the reputation as a skilled policy navigator and prominent American business envoy to Beijing.

But, in Trump 2.0, not only has Apple lost its crown to Nvidia as America’s most valuable company, several tech pundits say the AI darling’s charismatic leader, Jensen Huang, has left Cook far behind in political influence. 

“Huang has become a global figure and taken on a new role politically due to his success in the AI revolution,” said Wedbush’s Dan Ives, adding that the importance of Nvidia’s AI chips has “vaulted him ahead of Cook.”  

“He has found himself in a very strong position to navigate the political landscape … [as] there is only one chip in the world fueling the AI revolution, and that’s Nvidia’s,” Ives said.

The optics of Huang’s political ascendancy have never been stronger, as Nvidia last week announced during its CEO’s latest visit to Beijing that it expected to soon resume sales of its H20 AI chips to China.

The Nvidia CEO has met with Trump many times this year, including joining him on a trip to the Middle East in May, which resulted in a massive AI deal that will see the delivery of hundreds of thousands of Nvidia’s advanced AI chips to the United Arab Emirates. 

The Emirates deal had been seen as a way for America to push its global tech leadership, solidifying its technology stack in a new market over potential rivals like China’s Huawei.

After the trip, Huang increasingly began making a case against U.S. chip restrictions, arguing that they would erode America’s tech leadership to the benefit of domestic Chinese players. 

According to a report from the New York Times, this had also been a narrative Huang had been pushing to Trump and his officials behind the scenes. 

Paul Triolo, senior vice president for China, and technology policy lead at DGA-Albright Stonebridge Group, told CNBC that Huang’s arguments aligned with the thinking of influential White House AI and Crypto Czar David Sacks, further swaying the administration to lift restrictions on H20 chip exports. 

“Sacks and Huang both argue that limiting exports of U.S. technology such as select and non-cutting-edge GPUs to China risks pushing Chinese companies to use domestic alternatives … At the end of the day, this argument likely carried the day on the H20 issue,” he said. 

It’s unclear when or if Nvidia will restart production lines of the H20, but if Nvidia is simply able to sell existing stocks of H20s, it will still be a “significant revenue boost and beneficial to Nvidia in terms of retaining clients’ goodwill in China,” Triolo added.  Nvidia said it took a $4.5 billion writedown on its unsold H20 inventory in May.

Huang said last week that every civil AI model should run on the U.S. technology stack, “encouraging nations worldwide to choose America,” as Nvidia announced resuming H20 sales soon.

In November, experts told CNBC that Musk’s close ties to Trump and his business interests in China could help soften the president’s aggressive trade stance toward Beijing, while cautioning against putting too much stock into the Tesla CEO.

Meanwhile, under Trump’s second presidency, Apple’s Cook has seen some strong pushback from the administration.

In May, Trump expressed a “little problem with Tim Cook” over Apple manufacturing products in India, despite the iPhone maker’s commitment of a $500 billion investment in the U.S., announced in February.

In response to the latest trade tensions between China and the U.S., Apple has accelerated efforts to de-risk supply chains from China by moving more iPhone production to India.

Earlier this month, Trump adviser Peter Navarro also criticized Cook, saying he was not moving production out of China fast enough.  

Apple and Cook were seen as the most influential company and CEO, respectively, in the first Trump administration, but now its Huang and Nvidia, said Ray Wang, CEO of Silicon Valley-based Constellation Research Inc. “Almost everything rides on Nvidia’s chips.”
