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.

IBM shares fell as much as 5% in extended trading on Wednesday after the tech conglomerate issued second-quarter results that topped Wall Street projections.
Here’s how the company did in comparison with LSEG consensus:
- Earnings per share: $2.80 adjusted vs. $2.64 expected
- Revenue: $16.98 billion vs. $16.59 billion
IBM’s revenue increased nearly 8% year over year in the quarter, according to a statement. Growth in the first quarter was below 1%. Net income, which includes costs related to acquisitions, rose to $2.19 billion, or $2.31 per share, from $1.83 billion, or $1.96 per share, a year ago.
Software revenue climbed about 10% to $7.39 billion, exceeding the $7.43 billion consensus among analysts surveyed by StreetAccount. Hybrid cloud revenue, including Red Hat, showed 16% growth. The software unit’s gross margin of 83.9% was barely narrower than StreetAccount’s 84.0% consensus.
Revenue from consulting rose almost 3% to $5.31 billion, higher than StreetAccount’s $5.16 billion consensus. Infrastructure revenue went up 14% to $4.14 billion, above the $3.75 billion StreetAccount average estimate.
During the quarter, IBM announced the next-generation z17 mainframe computer and the acquisition of data and artificial intelligence consulting firm Hakkoda.
IBM called for over $13.5 billion in 2025 free cash flow, similar to a projection from April. The company still sees at least 5% revenue growth at constant currency for the year.
As of Wednesday’s close, IBM shares were up 28% so far in 2025, while the S&P 500 index has gained around 8% in the same period.
Executives will discuss the results with analysts on a conference call starting at 5 p.m. ET.

Texas Instruments shares plunged 12% after the automotive and industrial semiconductor supplier warned of ongoing tariff aftershocks.
The company said it expects third-quarter earnings between $1.36 and $1.60 per share, a midpoint of $1.48 per share. That fell short of an LSEG estimate of $1.50.
Texas Instruments anticipates revenues between $4.45 billion and $4.48 billion. The midpoint of $4.63 billion was slightly ahead of the $4.59 billion expected by analysts.
In an earnings call with analysts, CEO Haviv Ilan said the company is experiencing a “shallow” recovery in the automotive sector and said customers may have lingering worries over tariffs and geopolitical uncertainty.
Despite the post-earnings slump, Texas Instruments posted a 16% year-over-year jump in revenue. The company reported earnings of $1.41 per share on $4.45 billion in revenue, surpassing the earnings of $1.35 per share on $4.36 billion in revenue expected by LSEG analysts.
Ilan said that some of the second-quarter strength may have come from a pull forward in demand to acquire inventory ahead of tariffs.
Net income for the company rose 15% to $1.3 billion, or $1.41 per share, from $1.13 billion, or $1.22 per share, a year ago.
