What information was stolen?
According to a breach notification filed with the Maine Attorney General’s office, nearly 869,000 individuals were affected by the Columbia breach. This number includes students, employees, applicants and, in some cases, family members. Media outlets also reported that the threat actor claimed to have stolen approximately 460 gigabytes of data from Columbia’s systems.
Columbia confirmed that the stolen information relates to admissions, enrollment and financial aid records, as well as certain employee data. The categories of exposed information include:
- Names, dates of birth and Social Security numbers
- Contact details and demographic information
- Academic history and financial aid records
- Insurance details and certain health information
Columbia emphasized that patient records from Columbia University Irving Medical Center were not affected. Still, the breadth of stolen data poses serious risks of identity theft and fraud.

Columbia University response
Columbia has reported the incident to law enforcement and is working with cybersecurity experts. The university said it has strengthened its systems with new safeguards and enhanced protocols to prevent future incidents.
Starting Aug. 7, Columbia began mailing letters to those affected, offering two years of complimentary credit monitoring, fraud consultation and identity theft restoration services.
When contacted, Columbia referred CyberGuy to its official community updates, published June 24 and Aug. 5.
While the university says there is no evidence that the stolen data has been misused so far, the risk remains high. Criminals often wait months before exploiting stolen data.

Steps to protect yourself after the Columbia University breach
If you are among those affected or simply want to safeguard your data, take these steps today:
1) Monitor your credit reports
Check your credit reports regularly through AnnualCreditReport.com. Look for accounts you did not open or changes you did not authorize.
2) Use a personal data removal service
Since Columbia confirmed that stolen files may include names, addresses and demographic details, consider using a personal data removal service. These services help scrub your information from data brokers and people search sites, making it harder for criminals to exploit exposed details. This step reduces the chance that stolen Columbia records are linked to your broader online identity.
While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap, and neither is your privacy. These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you.

3) Set up fraud alerts and freezes
Placing a fraud alert makes it harder for identity thieves to open accounts in your name. A credit freeze offers even stronger protection by blocking new credit applications.
4) Use strong and unique passwords
Create long, complex passwords for each account. A password manager can help generate and securely store them.
Next, see if your email has been exposed in past breaches. Our No. 1 password manager (see Cyberguy.com/Passwords) pick includes a built-in breach scanner that checks whether your email address or passwords have appeared in known leaks. If you discover a match, immediately change any reused passwords and secure those accounts with new, unique credentials.
Check out the best expert-reviewed password managers of 2025 at Cyberguy.com/Passwords
5) Enable two-factor authentication
Turn on two-factor authentication (2FA) wherever possible. This extra layer of security helps protect your accounts even if a password is stolen.
6) Watch for phishing attempts and use strong antivirus software
Scammers may try to exploit fear around the breach with fake emails or texts. Verify any message before clicking links or sharing personal information.
The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe.

7) Consider identity theft protection services
Beyond the free credit monitoring Columbia offers, additional paid services can help track your data across the dark web and provide extra safeguards.
Identity theft companies can monitor personal information like your Social Security number, phone number and email address and alert you if it is being sold on the dark web or being used to open an account. They can also assist you in freezing your bank and credit card accounts to prevent further unauthorized use by criminals.

Kurt’s key takeaways
The Columbia University breach shows how even trusted institutions are vulnerable to cyberattacks. Because the investigation is ongoing and notifications will continue through the fall, individuals should remain on high alert. With so much personal, financial and health information exposed, staying alert long after the headlines fade is critical.
What more should universities and large institutions be required to do to safeguard the personal data of the people who trust them? Let us know by writing to us at Cyberguy.com/Contact

The future of local TV news has taken a Trumpian turn
A long time ago, in 2004, the Federal Communications Commission laid down a rule designed to prevent a monopoly: No one company could broadcast to more than 39 percent of all the TV households in the United States. But then Donald Trump returned to the White House in 2025. Brendan Carr became FCC chairman and immediately kicked off a deregulatory initiative called “Delete, Delete, Delete,” in which Carr vowed to get rid of “every rule, regulation, or guidance document” that placed “unnecessary regulatory burdens” on companies. And within months, Nexstar, which already owned over 200 stations nationwide and had hit its ownership cap, announced that it had entered an agreement to purchase its rival, Tegna, for an estimated $6.2 billion — something that could only happen, however, if Carr agreed to change the FCC’s rules.
If you ask Nexstar why it’s pursuing a merger that would give it control of over 80 percent of the market, it’d point to Big Tech as the culprit. As advertisers take their money to Netflix, YouTube, and other digital streamers, linear television — the local television news, the broadcast affiliates, the basic cable networks — has suffered, forcing them to consolidate and shut down newsrooms. In that sense, Nexstar argued, the merger would help it compete for ad revenue with the streaming services, thereby building more robust local journalism. However, the merger’s opponents believe that this is a basic violation of antitrust laws and principles — not to mention the danger of letting one company have editorial control over the vast majority of America’s local television newsrooms.
But the second Trump administration handles regulatory hurdles a little differently than others, and companies have found that it’s faster to get what they want if they bypass the agencies and talk (read: suck up) to Trump directly. And when Nexstar did so publicly, it confirmed its opponents’ fears about political influence. Last September, in the fraught weeks after the fatal shooting of Charlie Kirk, Nexstar announced it would no longer broadcast Jimmy Kimmel Live! — a response to Carr’s claim that the FCC could revoke the broadcast licenses of TV stations that aired the comedian’s comments related to Kirk. It briefly led to ABC suspending Kimmel’s show, though ABC and Nexstar soon reversed their decision after a massive nationwide backlash and an ABC boycott.
However, Nexstar’s loyalty to Trump himself was not enough to win over his most powerful MAGA supporters. Newsmax, a cable news network with a deeply pro-Trump bent, and its CEO, longtime Trump donor and outside adviser Chris Ruddy, filed a lawsuit objecting to the merger, claiming that Nexstar’s anticompetitive behavior would force channels like his off the air with steeper carriage fees. He specifically accused Nexstar of jacking up the fees for stations to carry Newsmax, while offering its similar network, NewsNation, for much cheaper.
The Nexstar-Tegna MAGA makeover then took a more subtle turn. NewsNation hired the pro-Trump Fox News commentator Katie Pavlich and gave her her own primetime show. (The network had already hired a slew of former Fox journalists as well.) Around this time, a political group called Keep News Local began airing ads in DC that seemed to directly address Trump, praising him for having “defeated the fake news monopolies before through independent voices and local news” and claiming that the Nexstar-Tegna merger was “crucial for MAGA to survive.” (A little self-contradictory and mildly illogical, but it’s the kind of stuff that Trump likes to hear.) When I last spoke to Ruddy in February, I asked if he’d worried that the dark money going into Keep News Local would sway Trump, and he chose his words carefully: “I think at the end of the day, Trump makes up his own mind. I’m not sure he’s going to be influenced by an ad campaign.”
For months, no one could accurately predict if Trump would override Carr’s wishes and bless the deal, as he’s often done for other companies facing regulatory scrutiny. Trump’s Truth Social posts about the merger have been a good indicator of how precarious the merger has been and who’s been able to influence him at any given moment: Last November, he blasted the deal as an “EXPANSION OF THE FAKE NEWS NETWORKS,” but by February, he posted that the deal would “help knock out the Fake News because there will be more competition.”
Several current and former NewsNation employees told Status at the time that they feared that the parent company was steering NewsNation away from the centrist, “unbiased” reputation they’d long cultivated. “A lot of people within the network believe that the network has gone hard right to appeal to Trump and Brendan Carr,” one former employee told Status. Coincidentally, days before the deal was finalized, NewsNation began ramping up its explicitly pro-Trump content, tweeting a clip of CNN’s Kaitlan Collins being berated by White House press secretary Karoline Leavitt, along with the comment “Just going to leave this here.”
When Trump greenlit the merger in mid-March, but before the FCC’s three commissioners could vote on whether to waive the ownership cap, Nexstar and Tegna immediately announced a new complication: Tegna and Nexstar had already started merging. Tegna was no more and CEO Mike Steib had already sold $22.6 million of his company stock.
In response, eight state attorneys general and satellite TV operator DirectTV, which had already been planning to file separate federal antitrust suits against the merger, asked US District Judge Troy Nunley in Sacramento for an emergency restraining order that would prevent Nexstar from taking over Tegna’s assets. The order was granted on March 27th and on April 17, Nunley issued a formal injunction, ruling that Tegna must be operated as an independent financial entity, and Nexstar must take steps to ensure it remains separate from Tegna before further legal proceedings.
For now, Nunley has allowed the states and DirecTV to combine their cases, in which both argue that the merger was a clear violation of antitrust laws and would crush news competition.
Meanwhile, Republicans and Democrats in Congress are furious at Carr. On March 30th, Sens. Ted Cruz (R-TX) and Maria Cantwell (D-WA) sent the chairman a joint letter admonishing him for allowing his staff to waive the regulations to let the merger pass, instead of having the full commission of political appointees — one from the Biden administration — vote on it. “Under these circumstances,” they wrote, “any subsequent vote risks being largely procedural rather than a genuine exercise of commission responsibility.” They also pointed out that their hasty approval without the commission’s approval would now complicate the merger financially: “In a transaction of this scale, where integration proceeds quickly and unwinding becomes impractical, delay in judicial review can insulate the decision from meaningful challenge.” Notably, though they share similar ideological views on the media and deregulation, Cruz and Carr have frequently clashed over how to achieve their objectives. Cruz previously slammed Carr as a “mafioso,” for instance, for the way he’d used the FCC to silence Kimmel.
But even if it’s legally paused, the journalistic merger’s fallout has started to hit local news. NPR’s David Folkenfirk reported on Tuesday that Tegna journalists had already started receiving orders to stop broadcasting content from major broadcasters like ABC, CBS, and NBC — media outlets being targeted by Carr — and instead begin airing content from Nexstar’s NewsNation.
- Brendan Carr’s views on using the FCC to punish major broadcasters was outlined pretty extensively in the chapter he authored in Project 2025, an initiative led by the conservative Heritage Foundation on how to reform the federal bureaucracy to be more favorable to the American right.
- Exactly how much is local television losing to digital? According to industry publication NewscastStudio, in an investor call defending the purchase, Nexstar chairman Perry Sook cited a market research study from Borrell Associates, which found that “digital advertising in local markets exceeds $100 billion, compared to just $25 billion for local linear television advertising, with nearly two-thirds of digital ad dollars flowing to five major technology companies.”

Chinese robot breaks human world record in Beijing half-marathon
NEWYou can now listen to Fox News articles!
A Chinese-built humanoid robot beat the human half-marathon world record in Beijing on Sunday, marking a breakthrough moment in a high-stakes global race for technological dominance.
A robot developed by Chinese smartphone maker Honor completed the 21-kilometer (13-mile) race in 50 minutes and 26 seconds, beating the human record of about 57 minutes set by Uganda’s Jacob Kiplimo last month.
The performance marked a dramatic improvement from last year’s inaugural event, when the top robot finished in more than 2 hours and 40 minutes.
Dozens of humanoid robots competed alongside about 12,000 human runners, navigating a parallel course to avoid collisions.

Nearly half of the robots ran using autonomous navigation, while others relied on remote control, organizers said.
Despite the breakthrough, the race still saw glitches, with some robots stumbling at the start or veering into barriers.
Engineers said the winning robot was designed to mimic elite athletes, featuring long legs of about 37 inches and advanced cooling systems to sustain performance.
US TARGETS CHINESE ROBOTS OVER SECURITY FEARS
“Looking ahead, some of these technologies might be transferred to other areas,” said Du Xiaodi, an engineer with the Honor team. “For example, structural reliability and liquid-cooling technology could be applied in future industrial scenarios.”

Spectators reacted with a mix of amazement and unease at the machines’ rapid progress.
“It’s the first time robots have surpassed humans, and that’s something I never imagined,” Sun Zhigang, who attended the event with his son, told The Associated Press.
HUMANOID ROBOTS HIT MASS PRODUCTION IN CHINA
“The robots’ speed far exceeds that of humans,” spectator Wang Wen told the outlet. “This may signal the arrival of sort of a new era.”

Experts say the race highlights China’s accelerating push to dominate robotics and artificial intelligence, even as widespread commercial use of humanoid robots remains limited, according to Reuters. The experts said Chinese robotics firms are still working to develop the AI software needed for humanoids to match the efficiency of human factory workers.

“The future will definitely be an AI era,” engineering student Chu Tianqi told Reuters. “If people don’t know how to use AI now … they will definitely become obsolete.”

The RAM shortage could last years
According to Nikkei Asia, even as suppliers ramp up DRAM production, manufacturers are only expected to meet 60 percent of demand by the end of 2027. SK Group chairman has even said that shortages could last until 2030.
The world’s largest memory makers — Samsung, SK Hynix, and Micron — are all working to add new fabrication capacity, but almost none of it will be online until at least 2027, if not 2028. SK opened a fab in Cheongju in February, but that is the only increase in production among the three for 2026.
Nikkei says that production would need to increase by 12 percent a year in 2026 and 2027 to meet demand. But according to Counterpoint Research, an increase of only 7.5 percent is planned.
The new facilities will primarily focus on producing high-bandwidth memory (HBM), which is used in AI data centers. With the companies already prioritizing HBM over general-purpose DRAM used in computers and phones, it’s not clear how much these new fabs will help alleviate the price crunch facing consumer electronics. Everything from phones and laptops, to VR headsets and gaming handhelds have seen price increases due to the RAM shortage.
