A recent Chinese cyber-espionage attack inside the nation’s major telecom networks that may have reached as high as the communications of President-elect Donald Trump and Vice President-elect J.D. Vance was designated this week by one U.S. senator as “far and away the most serious telecom hack in our history.”

The U.S. has yet to figure out the full scope of what China accomplished, and whether or not its spies are still inside U.S. communication networks.

“The barn door is still wide open, or mostly open,” Senator Mark Warner of Virginia and chairman of the Senate Intelligence Committee told the New York Times on Thursday.

The revelations highlight the rising cyberthreats tied to geopolitics and nation-state actor rivals of the U.S., but inside the federal government, there’s disagreement on how to fight back, with some advocates calling for the creation of an independent federal U.S. Cyber Force. In September, the Department of Defense formally appealed to Congress, urging lawmakers to reject that approach.

Among one of the most prominent voices advocating for the new branch is the Foundation for Defense of Democracies, a national security think tank, but the issue extends far beyond any single group. In June, defense committees in both the House and Senate approved measures calling for independent evaluations of the feasibility to create a separate cyber branch, as part of the annual defense policy deliberations.

Drawing on insights from more than 75 active-duty and retired military officers experienced in cyber operations, the FDD’s 40-page report highlights what it says are chronic structural issues within the U.S. Cyber Command (CYBERCOM), including fragmented recruitment and training practices across the Army, Navy, Air Force, and Marines.

“America’s cyber force generation system is clearly broken,” the FDD wrote, citing comments made in 2023 by then-leader of U.S. Cyber Command, Army General Paul Nakasone, who took over the role in 2018 and described current U.S. military cyber organization as unsustainable: “All options are on the table, except the status quo,” Nakasone had said.

Concern with Congress and a changing White House

The FDD analysis points to “deep concerns” that have existed within Congress for a decade — among members of both parties — about the military being able to staff up to successfully defend cyberspace. Talent shortages, inconsistent training, and misaligned missions, are undermining CYBERCOM’s capacity to respond effectively to complex cyber threats, it says. Creating a dedicated branch, proponents argue, would better position the U.S. in cyberspace. The Pentagon, however, warns that such a move could disrupt coordination, increase fragmentation, and ultimately weaken U.S. cyber readiness.

As the Pentagon doubles down on its resistance to establishment of a separate U.S. Cyber Force, the incoming Trump administration could play a significant role in shaping whether America leans toward a centralized cyber strategy or reinforces the current integrated framework that emphasizes cross-branch coordination.

Known for his assertive national security measures, Trump’s 2018 National Cyber Strategy emphasized embedding cyber capabilities across all elements of national power and focusing on cross-departmental coordination and public-private partnerships rather than creating a standalone cyber entity. At that time, the Trump’s administration emphasized centralizing civilian cybersecurity efforts under the Department of Homeland Security while tasking the Department of Defense with addressing more complex, defense-specific cyber threats. Trump’s pick for Secretary of Homeland Security, South Dakota Governor Kristi Noem, has talked up her, and her state’s, focus on cybersecurity.

Former Trump officials believe that a second Trump administration will take an aggressive stance on national security, fill gaps at the Energy Department, and reduce regulatory burdens on the private sector. They anticipate a stronger focus on offensive cyber operations, tailored threat vulnerability protection, and greater coordination between state and local governments. Changes will be coming at the top of the Cybersecurity and Infrastructure Security Agency, which was created during Trump’s first term and where current director Jen Easterly has announced she will leave once Trump is inaugurated.

Cyber Command 2.0 and the U.S. military

John Cohen, executive director of the Program for Countering Hybrid Threats at the Center for Internet Security, is among those who share the Pentagon’s concerns. “We can no longer afford to operate in stovepipes,” Cohen said, warning that a separate cyber branch could worsen existing silos and further isolate cyber operations from other critical military efforts.

Cohen emphasized that adversaries like China and Russia employ cyber tactics as part of broader, integrated strategies that include economic, physical, and psychological components. To counter such threats, he argued, the U.S. needs a cohesive approach across its military branches. “Confronting that requires our military to adapt to the changing battlespace in a consistent way,” he said.

In 2018, CYBERCOM certified its Cyber Mission Force teams as fully staffed, but concerns have been expressed by the FDD and others that personnel were shifted between teams to meet staffing goals — a move they say masked deeper structural problems. Nakasone has called for a CYBERCOM 2.0, saying in comments early this year “How do we think about training differently? How do we think about personnel differently?” and adding that a major issue has been the approach to military staffing within the command.

Austin Berglas, a former head of the FBI’s cyber program in New York who worked on consolidation efforts inside the Bureau, believes a separate cyber force could enhance U.S. capabilities by centralizing resources and priorities. “When I first took over the [FBI] cyber program … the assets were scattered,” said Berglas, who is now the global head of professional services at supply chain cyber defense company BlueVoyant. Centralization brought focus and efficiency to the FBI’s cyber efforts, he said, and it’s a model he believes would benefit the military’s cyber efforts as well. “Cyber is a different beast,” Berglas said, emphasizing the need for specialized training, advancement, and resource allocation that isn’t diluted by competing military priorities.

Berglas also pointed to the ongoing “cyber arms race” with adversaries like China, Russia, Iran, and North Korea. He warned that without a dedicated force, the U.S. risks falling behind as these nations expand their offensive cyber capabilities and exploit vulnerabilities across critical infrastructure.

Nakasone said in his comments earlier this year that a lot has changed since 2013 when U.S. Cyber Command began building out its Cyber Mission Force to combat issues like counterterrorism and financial cybercrime coming from Iran. “Completely different world in which we live in today,” he said, citing the threats from China and Russia.

Brandon Wales, a former executive director of the CISA, said there is the need to bolster U.S. cyber capabilities, but he cautions against major structural changes during a period of heightened global threats.

“A reorganization of this scale is obviously going to be disruptive and will take time,” said Wales, who is now vice president of cybersecurity strategy at SentinelOne.

He cited China’s preparations for a potential conflict over Taiwan as a reason the U.S. military needs to maintain readiness. Rather than creating a new branch, Wales supports initiatives like Cyber Command 2.0 and its aim to enhance coordination and capabilities within the existing structure. “Large reorganizations should always be the last resort because of how disruptive they are,” he said.

Wales says it’s important to ensure any structural changes do not undermine integration across military branches and recognize that coordination across existing branches is critical to addressing the complex, multidomain threats posed by U.S. adversaries. “You should not always assume that centralization solves all of your problems,” he said. “We need to enhance our capabilities, both defensively and offensively. This isn’t about one solution; it’s about ensuring we can quickly see, stop, disrupt, and prevent threats from hitting our critical infrastructure and systems,” he added.

How TikTok’s rise sparked a short-form video race

How TikTok’s rise sparked a short-form video race

TikTok’s grip on the short-form video market is tightening, and the world’s biggest tech platforms are racing to catch up.

Since launching globally in 2016, ByteDance-owned TikTok has amassed over 1.12 billion monthly active users worldwide, according to Backlinko. American users spend an average of 108 minutes per day on the app, according to Apptoptia.

TikTok’s success has reshaped the social media landscape, forcing competitors like Meta and Google to pivot their strategies around short-form video. But so far, experts say that none have matched TikTok’s algorithmic precision.

“It is the center of the internet for young people,” said Jasmine Enberg, vice president and principal analyst at Emarketer. “It’s where they go for entertainment, news, trends, even shopping. TikTok sets the tone for everyone else.”

Platforms like Meta‘s Instagram Reels and Google’s YouTube Shorts have expanded aggressively, launching new features, creator tools and even considering separate apps just to compete. Microsoft-owned LinkedIn, traditionally a professional networking site, is the latest to experiment with TikTok-style feeds. But with TikTok continuing to evolve, adding features like e-commerce integrations and longer videos, the question remains whether rivals can keep up.

“I’m scrolling every single day. I doom scroll all the time,” said TikTok content creator Alyssa McKay.

But there may a dark side to this growth.

As short-form content consumption soars, experts warn about shrinking attention spans and rising mental-health concerns, particularly among younger users. Researchers like Dr. Yann Poncin, associate professor at the Child Study Center at Yale University, point to disrupted sleep patterns and increased anxiety levels tied to endless scrolling habits.

“Infinite scrolling and short-form video are designed to capture your attention in short bursts,” Dr. Poncin said. “In the past, entertainment was about taking you on a journey through a show or story. Now, it’s about locking you in for just a few seconds, just enough to feed you the next thing the algorithm knows you’ll like.”

Despite sky-high engagement, monetizing short videos remains an uphill battle. Unlike long-form YouTube content, where ads can be inserted throughout, short clips offer limited space for advertisers. Creators, too, are feeling the squeeze.

“It’s never been easier to go viral,” said Enberg. “But it’s never been harder to turn that virality into a sustainable business.”

Last year, TikTok generated an estimated $23.6 billion in ad revenues, according to Oberlo, but even with this growth, many creators still make just a few dollars per million views. YouTube Shorts pays roughly four cents per 1,000 views, which is less than its long-form counterpart. Meanwhile, Instagram has leaned into brand partnerships and emerging tools like “Trial Reels,” which allow creators to experiment with content by initially sharing videos only with non-followers, giving them a low-risk way to test new formats or ideas before deciding whether to share with their full audience. But Meta told CNBC that monetizing Reels remains a work in progress.

While lawmakers scrutinize TikTok’s Chinese ownership and explore potential bans, competitors see a window of opportunity. Meta and YouTube are poised to capture up to 50% of reallocated ad dollars if TikTok faces restrictions in the U.S., according to eMarketer.

Elon Musk‘s xAI Holdings is in discussions with investors to raise about $20 billion, Bloomberg News reported Friday, citing people familiar with the matter.

The funding would value the company at over $120 billion, according to the report.

Musk was looking to assign “proper value” to xAI, sources told CNBC’s David Faber earlier this month. The remarks were made during a call with xAI investors, sources familiar with the matter told Faber. The Tesla CEO at that time didn’t explicitly mention any upcoming funding round, but the sources suggested xAI was preparing for a substantial capital raise in the near future.

The funding amount could be more than $20 billion as the exact figure had not been decided, the Bloomberg report added.

Artificial intelligence startup xAI didn’t immediately respond to a CNBC request for comment outside of U.S. business hours.

The AI firm last month acquired X in an all-stock deal that valued xAI at $80 billion and the social media platform at $33 billion.

“xAI and X’s futures are intertwined. Today, we officially take the step to combine the data, models, compute, distribution and talent,” Musk said on X, announcing the deal. “This combination will unlock immense potential by blending xAI’s advanced AI capability and expertise with X’s massive reach.”

Alphabet jumps 3% as search, advertising units show resilient growth

Alphabet‘s stock gained 3% Friday after signaling strong growth in its search and advertising businesses amid a competitive artificial intelligence environment and uncertain macro backdrop.

GOOGL‘s pace of GenAI product roll-out is accelerating with multiple encouraging signals,” wrote Morgan Stanley‘s Brian Nowak. “Macro uncertainty still exists but we remain [overweight] given GOOGL’s still strong relative position and improving pace of GenAI enabled product roll-out.”

The search giant posted earnings of $2.81 per share on $90.23 billion in revenues. That topped the $89.12 billion in sales and $2.01 in EPS expected by LSEG analysts. Revenues grew 12% year-over-year and ahead of the 10% anticipated by Wall Street.

Net income rose 46% to $34.54 billion, or $2.81 per share. That’s up from $23.66 billion, or $1.89 per share, in the year-ago period. Alphabet said the figure included $8 billion in unrealized gains on its nonmarketable equity securities connected to its investment in a private company.

Adjusted earnings, excluding that gain, were $2.27 per share, according to LSEG, and topped analyst expectations.

Alphabet shares have pulled back about 16% this year as it battles volatility spurred by mounting trade war fears and worries that President Donald Trump‘s tariffs could crush the global economy. That would make it more difficult for Alphabet to potentially acquire infrastructure for data centers powering AI models as it faces off against competitors such as OpenAI and Anthropic to develop largely language models.

During Thursday’s call with investors, Alphabet suggested that it’s too soon to tally the total impact of tariffs. However, Google’s business chief Philipp Schindler said that ending the de minimis trade exemption in May, which created a loophole benefitting many Chinese e-commerce retailers, could create a “slight headwind” for the company’s ads business, specifically in the Asia-Pacific region. The loophole allows shipments under $800 to come into the U.S. duty-free.

Despite this backdrop, Alphabet showed steady growth in its advertising and search business, reporting $66.89 billion in revenues for its advertising unit. That reflected 8.5% growth from the year-ago period. The company reported $8.93 billion in advertising revenue for its YouTube business, shy of an $8.97 billion estimate from StreetAccount.

Alphabet’s “Search and other” unit rose 9.8% to $50.7 billion, up from $46.16 billion last year. The company said that its AI Overviews tool used in its Google search results page has accumulated 1.5 billion monthly users from a billion in October.

Bank of America analyst Justin Post said that Wall Street is underestimating the upside potential and “monetization ramp” from this tool and cloud demand fueled by AI.

“The strong 1Q search performance, along with constructive comments on Gemini [large language model] performance and [AI Overviews] adoption could help alleviate some investor concerns on AI competition,” Post wrote in a note.
