Senator Ron Wyden, D-Ore., the chair of the powerful Senate Finance Committee, demanded on Thursday that the Justice Department and two civil regulators open separate probes into Microsoft’s “negligent cybersecurity practices” that led to a high-level, targeted hack targeting the highest echelons of President Joe Biden’s cabinet.
Chinese hackers accessed the Microsoft-powered email accounts of top China envoys, Commerce Secretary Gina Raimondo, and Secretary of State Antony Blinken. The intrusion, from May to June, occurred just ahead of a critical Sino-U.S. meeting.
Senator Wyden sent the letter to attorney general Merrick Garland, Federal Trade Commission chair Lina Khan, and Cybersecurity and Infrastructure Security Agency director Jen Easterly on Thursday.
Microsoft shares fell about 1% in Thursday morning trading.
“Government emails were stolen because Microsoft committed another error. Although the stolen encryption key was for consumer accounts, ‘a validation error in Microsoft code’ allowed the hackers to also create fake tokens for Microsoft-hosted accounts for government agencies and other organizations, and thereby access those accounts,” Wyden wrote.
Wyden asked that the Justice Department examine whether Microsoft had violated federal law through its negligence; that CISA examine whether Microsoft violated best practices for securing the highly sensitive “skeleton key;” and that the Federal Trade Commission examine whether Microsoft violated federal privacy statutes.
Wyden’s directive to the FTC focused on privacy concerns, but the agency could also examine whether Microsoft’s dominance in the cloud computing market led to heightened risk through anti-competitive behavior. That allegation has been raised by rivals and cybersecurity operators, including Google.
“While Microsoft’s engineers should never have deployed systems that violated such basic cybersecurity principles, these obvious flaws should have been caught by Microsoft’s internal and external security audits,” Wyden said.
A spokesperson for the FTC confirmed the agency had received the letter but declined to comment further. CISA and Microsoft did not immediately respond to requests for comment.
Cybersecurity experts have expressed mounting concern over the intrusion, which impacted at least a dozen government organizations worldwide. Both the State Department and the Commerce Department were targeted by Chinese hackers.
The State Department’s cyber team informed Microsoft of the attack, and was only able to do so because it had engineered more granular reporting and logging. After the hack, Microsoft said it would stop charging for the sophisticated logging and offer it for free.
Wyden noted it wasn’t the first time that a foreign government had hacked government agencies by exploiting Microsoft vulnerabilities.
“The Russian hackers behind the 2020 SolarWinds hacking campaign used a similar technique,” Wyden noted. “Moreover, while Microsoft had known since 2017 that such keys could be quietly exfiltrated from customer servers running its software, it failed to warn its customers, including government agencies, about this risk.”
Both Microsoft and federal officials have disclosed relatively little about the hack, though Microsoft has disseminated additional information and made concessions to customers to mitigate the impact of the exploitation.

China has been using its dominance in the rare earth industry to slash prices, driving foreign competitors out, U.S. Treasury Secretary Scott Bessent told CNBC on Wednesday stateside in an exclusive interview. He characterized the country as having “a nonmarket economy.”
In response, the Trump administration will “exercise industrial policy” to set price floors in a range of industries. Price floors are a limit of how low suppliers can charge for goods or services. They are typically set above the market rate and are essentially a form of government price control.
Meanwhile, Bank of America and Morgan Stanley reported blockbuster second-quarter earnings that shot way past analyst expectations. They joined other major U.S. banks, such as JPMorgan Chase and Goldman Sachs, in ihaving a blowout quarter that was turbocharged by robust dealmaking and stock market highs.
And despite U.S. President Donald Trump’s continued saber-rattling at China on the trade front, traders don’t seem ready to let go of equities. On Wednesday stateside, the S&P 500 and Nasdaq Composite rose, and the Russell 2000 hit a fresh record. After all, earnings reports are indicating that the economy isn’t yet faltering, despite firms already experiencing higher costs because of tariffs, according to the U.S. Federal Reserve’s Beige Book.
Whether traders continue pushing equities to new highs amid fractious trade relations with China will depend, in part, on the earnings of major technology companies such as Tesla and Intel due next week.

UAE National Security Advisor, Sheikh Tahnoon bin Zayed Al Nahyan meets with U.S. President Donald Trump in the White House on March 18, 2025.
Backed by Abu Dhabi’s sovereign wealth fund and launched in March 2024, MGX has emerged as a key source of capital as companies race to build out the enormous computing power needed to meet expected AI demand.
Certain transactions suggest a level of coziness with Trump.
Earlier this year, MGX reportedly provided $2 billion in funding to the crypto exchange Binance, using a cryptocurrency purchased from the Trump family’s World Liberty Financial. Its chairman Tahnoon bin Zayed Al Nahyan also visited Trump in the White House this spring to announce a $1.4 trillion investment in the U.S. over the next decade.

Arm Holdings CEO Rene Haas told CNBC’s Jim Cramer on Wednesday that moving some AI functions away from the could help reduce energy usage.
Over time, he suggested, a large number of multi-gigawatt data centers won’t be sustainable.
“You look to yourself, well, what are the kind of things that need to happen? I think there’s two vectors to it,” Haas said. “One is low power, the lowest power solution you can get in the cloud. Arm really contributes there. But I think even more specifically is moving those AI workloads away from the cloud to local applications.”
While he said AI training will likely always happen in the cloud, running AI, called inference, can happen locally — meaning on the chips inside people’s phones, computers and glasses. History has shown “we always go to hybrid models around computing,” according to Haas.
He suggested that hybrid dynamic will play out when it comes to AI, which will help alleviate huge power investments.
Chip designer Arm’s technology powers devices made by a number of major Big Tech players, including Microsoft and Amazon. Semiconductor giant Nvidia has a major stake in Arm and actually attempted to acquire the company in 2020.
Arm and Meta on Wednesday said they would expand their partnership to “scale AI efficiency across every layer of compute – spanning AI software and data center infrastructure,” according to a press release. Arm stock saw gains following the announcement, finishing the day up 1.49%.
Haas told Cramer that the partnership with Meta is “largely around data centers, but more broadly…around software and the software stacks associated with it.” He also discussed Arm’s involvement in Meta’s new Ray-Ban Wayfarer glasses, saying the AI for the technology is running both in the cloud and locally.
“For example, when you say, ‘hey, Meta,’ into those glasses, that’s not happening on the cloud, that’s actually happening in your glasses, and that’s running on Arm,” Haas said.

Marc Benioff, chief executive officer of Salesforce Inc., speaks during the 2025 Dreamforce conference in San Francisco, California, US, on Tuesday, Oct. 14, 2025.

Salesforce shares rose as much as 5% in extended trading on Wednesday after the software vendor issued new financial targets for the next few years.
The company said it now expects revenue of over $60 billion in 2030, above the $58.37 billion consensus among analysts polled by LSEG.
The guidance excludes impact from the pending acquisition of data management company Informatica. The $8 billion deal, announced in May, is slated to close in the fiscal fourth quarter or in the first quarter of the 2027 fiscal year.
“We have had some lower-stage growth for a while,” Robin Washington, Salesforce’s chief operating and financial officer, said during an investor briefing at the company’s annual Dreamforce conference in San Francisco. “That is reaccelerating.”
She company called for an organic year-over-year revenue growth rate above 10% in the 2026 through 2030 fiscal years. The growth rate has been under 10% since mid-2024.
Investors have been concerned, in part because of the rise of “vibe-coding” tools for automatically generating software with a few words of human input. Industry observers have predicted that artificial intelligence services might threaten longstanding software providers. Microsoft CEO Satya Nadella said in April that AI is creating up to 30% of new code at the company.
“There’s a certain amount of, let’s just say, nonsense that’s out there,” Salesforce CEO Marc Benioff said on Wednesday. “Like, for example, that these products are writing all the software, and that is not what’s happening.”
As of Wednesday’s close, Salesforce’s stock had fallen 29% for the year, while the Nasdaq has gained 17%.
To increase revenue, Salesforce is counting on its Agentforce software for automating customer service and other business processes, said Washington, who also sits on Salesforce’s board. The company introduced Agentforce last year as a way for brands to add chat-based customer service agents that connect large language models to internal data.
“Investors continue to ask why Agentforce adoption has been slower than anticipated,” analysts at RBC Capital Markets wrote in a note to clients earlier this month.
Salesforce executives are hoping product enhancements will attract more business.
The company on Monday released Agentforce Voice, which allows clients to have agents answer customer service calls. On Tuesday, Salesforce announced larger partnerships with AI model developers Anthropic and OpenAI, bringing their latest models to Agentforce.
At Dreamforce, Salesforce pointed to Agentforce adoption at FedEx, Pandora, PepsiCo, Williams Sonoma and other companies.
