  • Quantum computers threaten exposed private keys rather than blockchains, Europol warns

    Quantum computers threaten exposed private keys rather than blockchains, Europol warns

    The agency aimed to draw a clear distinction often lost in warnings about quantum computing: the hash functions that help secure a blockchain’s history, including bitcoin mining, remain far more resistant to quantum attacks than the public-key cryptography used to control wallets.

    “Cryptocurrencies will not collapse due to quantum computing,” Europol said. The immediate concern is ownership of the assets held in wallets, not whether a quantum computer could rewrite the bitcoin blockchain.

    That distinction is more critical for addresses from the earliest days of Bitcoin – referred to as the “Satoshi era” – whose public keys have already become visible onchain. A powerful enough quantum computer could use those keys to drive the corresponding private key. Roughly 6.9 million bitcoin sit in addresses with exposed public keys, including early pay-to-topublic-key outputs and many long-dormant holdings.

    Europol said exposed keys cannot be made safe retroactively, an issue that has sparked massive debates and controversies across the bitcoin community as the dilemma of whether or not to freeze BTC in Satoshi-era wallets increases as the quantum threat nears.

    The more difficult task today is updating the network itself. Europol cited a 2024 study estimating that converting every bitcoin unspent transaction output, or UTXO, to a quantum-resistant format would require at least 76 days of cumulative block space. Reserving 25% of each block for the migration, that study adds, would stretch that process to about 300 days.

    At this point, Srinivasan says that Bitcoin could become the reserve currency of Western institutions, while Zcash would become the currency used by individuals for financial privacy.

    Emphasis on Institutional Reserves for Bitcoin, Zcash for Individuals!

    According to Srinivasan’s assessment, Bitcoin could assume the role of a reserve currency or reserve asset, particularly for Western institutions seeking to demonstrate solvency and financial soundness.

    This approach reinforces the idea that Bitcoin could move beyond being merely a digital asset preferred by individual investors and instead occupy a more significant position in the balance sheet and reserve strategies of institutions.

    Srinivasan also pointed out a different cryptocurrency for individual users. According to him, Zcash can be used as a form of money for individuals who want to protect their financial privacy.

    Srinivasan also considered $ZEC as a shield that could help users regain the financial privacy they have lost. This view is based on the expectation that the privacy-focused technology, one of Zcash’s core features, may become even more important in the future.

  • The Microsoft Event Is Here: New Surface Hardware and the Next Era of Windows AI

    The Microsoft Event Is Here: New Surface Hardware and the Next Era of Windows AI

    At Microsoft’s Surface and Windows event today, I’m hoping to learn more details about the Surface Laptop Ultra and get a better handle on the company’s long-term Windows strategy. I’ll be live-blogging about all the announcements as they happen alongside my colleague Brian Westover, who is reporting live from the event.

    Meanwhile, Microsoft’s new head of Copilot says it is a business productivity tool first and foremost, which is a stark departure from how the previous lead argued it was an intimate life companion. (Yes, seriously!) But that doesn’t interest me so much as the company’s continued memory optimization work on Windows 11.

    Read on for everything you need to know about Microsoft’s fall event, Copilot’s new business focus, and the Windows team’s most recent memory efficiency promises.

    Microsoft’s AI Problem, Explained by Someone Who Loves Windows


    Follow Our Live Coverage of Microsoft’s Big Windows Event

    PCMag’s principal hardware writer Brian Westover will be on the ground in San Francisco to cover Microsoft’s Surface and Windows event today. The event starts at 10 a.m. PT (1 p.m. EST), and he and I will be posting news, impressions, and analysis to a live blog throughout the week. If you want to watch the presentation yourself, you can always tune into Microsoft’s live video stream.

    At the event, we’re expecting an hour-long conversation followed by demonstrations for attendees. Microsoft CEO Satya Nadella, Microsoft head of Windows and Devices Pavan Davuluri, and Nvidia CEO Jensen Huang will all be in attendance, so it’s a good bet that the RTX Spark-powered Surface Laptop Ultra will be a major topic of conversation. I shared my predictions for Windows a few weeks ago, and here’s what Brian expects.


    Microsoft recently merged the business and consumer versions of its Copilot app, removing a variety of consumer-focused features in the process, including the animated Copilot Mico avatar and the ability to change Windows settings. Moreover, Satya Nadella called Copilot an “OS for work,” further cementing its identity as a productivity-focused business tool. In a report from The Verge, the new head of Copilot, Jacob Andreou, even described Copilot (and the Microsoft 365 suite) as a business-focused productivity tool that some people choose to use at home rather than something meant for home use.

    This represents a massive shift in the company’s vision for Copilot. Mustafa Suleyman, Microsoft’s previous head of Copilot, envisioned it as an AI companion that would know you “so intimately and so personally that it will come to live life alongside you.” He also said that “Copilot will certainly have a kind of permanent identity” and that “it will have a room that it lives in, and it will age.” Suleyman is now in charge of Microsoft AI, where he works on underlying Microsoft AI models rather than Copilot itself, so his vision appears to have fallen out of favor internally.

    I don’t think either approach is correct. I’d still much rather Microsoft focus on making it into as useful an assistant as Apple’s Siri in macOS rather than a business tool or life companion.

    Windows 11 Memory Usage Remains a Top Priority

    Microsoft’s Pavan Davaluri claims that memory usage is “top of mind” for the industry. He says the Windows team has work to do, and that engineers are trying to improve the memory efficiency of both apps and the OS itself. Windows Latest reported the statement from a recent episode of Microsoft’s Inside Windows podcast in which Davaluri sat down with Microsoft design and research lead Marcus Ash. Specifically, Ash describes “hidden but deep performance and reliability work” on Widgets and other aspects of the OS, detailing that most of Microsoft’s engineers are working on low-level improvements to the OS.

    The RAM crisis is unsurprisingly forcing Microsoft to rethink its OS priorities across the board. Windows 11’s 26H2 update brings relatively minor memory-efficiency improvements, so I hope more are on the way.

    Girard B. asks: “Will Microsoft add Print to the File Explorer context menu? I never understood why it went missing in the first place. Also, will Microsoft speed up File Explorer search? It’s always been painfully slow.”

    Hi Girard, thanks for your question! Windows 11’s shiny new context menus don’t include a Print option, but the classic context menus still do. To find it, hold the Shift key when you right-click a file in File Explorer, or right-click a file normally and select Show More Options.

    Microsoft likely removed this option to streamline its menus. However, after five years, Windows 11 is finally getting customizable context menus, which means you can add the Print option back. I’ve tried the new customizable menus, and they’re a huge improvement. This feature is already available in Insider builds, and it might arrive in stable builds in the coming months. Stay tuned!

    As far as File Explorer’s search feature, you can make it faster by heading to Settings > Privacy & Security > Search. Under Find my files, activate an Enhanced index, and Windows will search everything on your PC faster. If you’re not satisfied with the file search speed after enabling this setting, I recommend trying the free Everything app, which is my lightning-fast file search tool of choice.

  • US arrests suspect in connection with Tumbler Ridge school shooting

    US arrests suspect in connection with Tumbler Ridge school shooting

    The suspect, from the western state of Washington, allegedly gave money and advice to the attacker over the internet.

    Law enforcement in the northwestern United States have charged a suspect in connection with a deadly shooting at a Canadian school in Tumbler Ridge, British Columbia.

    On Tuesday, prosecutors charged 30-year-old James Cody Bryant, a resident of Washington state, with conspiracy to murder persons in a foreign country.

    list of 3 itemsend of list

    Bryant allegedly provided money and technical advice to the attacker in conversations over the internet, starting six months before the February 10 attack.

    The shooting was “a horrific tragedy for that small community and for all of Canada”, acting US Attorney Neil Floyd said at a news conference in Seattle. “Indeed, here in the Pacific Northwest, we felt the pain of those families devastated by this violence.”

    Canadian officials have described the attack as one of the country’s worst mass shootings.

    The suspect, 18-year-old transgender woman Jesse Van Rootselaar, shot and killed her mother and half-brother at their home before travelling to the Tumbler Ridge Secondary School and opening fire.

    Six people were killed, including five students, and 27 other victims were injured. Van Rootselaar, a former student at the school, died by suicide at the end of the attack.

    Police in Canada said at the time that Van Rootselaar had a history of mental health issues.

    Alleged online advice and financial support

    US prosecutors allege Bryant and Van Rootselaar had been in touch through the social media service Discord and had discussed how to carry out the mass shooting.

    The pair discussed how to maximise notoriety after the attack, with Bryant allegedly agreeing to livestream it through Twitch, Floyd said on Tuesday.

    Bryant also allegedly provided money for items like a pair of shoes for the attack and instructed Van Rootselaar on how to start and then drive a car to reach the school.

    Prosecutors alleged Bryant, whom officials cited by The Associated Press and Reuters say identifies as female, had admitted to investigators that she was “maybe the only one who could have stopped the shooter”.

    Warning signs ignored

    In September, the British Columbia government sued the technology company OpenAI in a California court, saying its ChatGPT platform played a role in the shooting.

    Van Rootselaar, the Canadian officials alleged, had been flagged by OpenAI’s safety team for her statements about gun violence, and her account had been suspended. But law enforcement authorities were not alerted to the problem.

    In its lawsuit, British Columbia sought financial compensation from the company to cover its emergency response to the shooting and community recovery efforts.

    It also asked the court to force OpenAI to reform how it identifies and handles users who threaten violence.

    OpenAI CEO Sam Altman said he was “deeply sorry” his company had not contacted law enforcement in a public letter two months after the shooting.

    “While I know words can never be enough, I believe an apology is necessary to recognize the harm and irreversible loss your community has suffered,” he wrote, adding that OpenAI would take steps to prevent such “tragedies” in the future.

    The lawsuit filed in California alleges Altman’s company never undertook the promised policy changes.

    By the time of the filing, OpenAI was facing more than 30 other lawsuits in California, where it is based, from victims’ families, survivors and others affected by the Tumbler Ridge attack over alleged negligence.

  • Ring’s First Smart Lock Comes With a Clever Solution for Dead Batteries

    Ring’s First Smart Lock Comes With a Clever Solution for Dead Batteries

    Ring has been synonymous with video doorbells and home security cameras for years, but it hasn’t really made a way to physically secure front doors with its products until now. The company just announced its first smart lock, and it comes with a (literally) powerful twist.

    The Ring Smart Lock looks like a standard smart lock equipped with multiple ways to unlock it. You can use an app, Alexa, the built-in fingerprint reader, or the number pad to unlock manually. That’s a solid suite of verification methods, even if it doesn’t extend to rarer biometric lock tech like the Lockly Visage Zeno’s facial recognition or the Lockin Veno Pro’s palm-vein reader.

    It also has a feature I haven’t seen in any other smart lock yet, albeit one that doesn’t directly lock or unlock anything. When a smart lock’s battery runs dry, it obviously can’t unlock your door. Some smart locks have hidden ports or charging contacts so you can give them enough juice to function, but the Ring Smart Lock takes a different approach. It has a power dial you can turn to generate just enough power to drive the lock, basically letting you crank-start it so you can get inside and fully charge the battery. It’s a simple but clever solution to the problem.

    The Ring Smart Lock retails for $249 and comes in black, silver, and brass finishes. You won’t see any of them for a few months, though; the lock doesn’t ship until early 2027.

    New models in Ring’s bread-and-butter category of security cameras were also just announced, and they’ll be coming out much sooner. They’re higher-resolution versions of cameras Ring already offers, and include the Ring Pan-Tilt Indoor Cam in 2K ($69.99), the Ring Indoor Cam Plus in 4K ($99.99), the Ring Outdoor Cam Plus in 4K, ($149.99), the Ring Spotlight Cam Plus in 4K ($199.99), and the Ring Floodlight Cam Plus in 4K ($219.99).

  • CNN, CBS News now under one roof as Paramount-Warner Bros merger closes

    CNN, CBS News now under one roof as Paramount-Warner Bros merger closes

    Paramount Skydance has completed its $110bn merger with Warner Bros Discovery to form Skydance.

    The deal, which closed on Tuesday, brings together two entertainment giants that own movie studios and theme parks, but also brings two of the United States’ most influential news brands under one roof — CNN and CBS News.

    list of 4 itemsend of list

    Skydance CEO David Ellison, son of tech tycoon Larry Ellison, who is also a close ally of US President Donald Trump, has appointed Ynon Kreiz as co-CEO. Kreiz previously led Mattel.

    The road to the merger has included lawsuits from unions and 12 different state attorneys general. But the deal was ultimately settled after the company agreed to appoint an independent editorial board to oversee both news networks amid concerns that the merger would lead to skewed coverage at the two networks.

    On Monday, the company announced that Mark Thompson will stay on as CNN’s editor-in-chief, while Bari Weiss, editor-in-chief at CBS News, who was appointed to the role a year ago on Monday, will stay in her position.

    Thompson’s continuation brought “a sigh of relief” among journalists at CNN, its media industry newsletter, Reliable Sources, reported.

    Ever since the merger had been announced, there had been a wave of concerns at the network that major changes would be made to CNN if the Ellisons took over.

    A looming future

    There are still a lot of unknowns about what news will look like under Skydance. In a memo to staffers on Monday, Thompson said that “the specifics of how CNN will plug into and operate in the new company have yet to be finalized.”

    That means looming fears of layoffs and consolidation still weigh on both news divisions as the combined company will carry $80bn in debt, while the entertainment giants look to cut costs, grow their streaming footprint and have pledged to produce 30 movies per year.

    Thompson’s stay may be temporary, as The New York Times reported that his contract is up in the spring.

    It is also not yet clear whether the networks will stay separate or combine in the long term, amid concerns that CBS News’ Weiss could be handed additional charge of CNN. In the past, the network’s top talent, including journalist Anderson Cooper, has threatened to leave if she came on board.

    Weiss took over the network one year ago, and viewership has slumped across the board. Most recently, the news magazine programme 60 Minutes saw viewership slump during its season premiere last month, dropping 21 percent from the prior year and marking its worst viewership for a season premiere in 25 years, according to Nielsen ratings.

    Editorial questions

    The terms of the attorneys general’s lawsuit settlement require an independent editorial oversight board for both the networks. Skydance has 180 days to put it together. Press freedom experts do not believe that will help maintain editorial independence.

    “It doesn’t take effect for 180 days. The newsroom can be totally overhauled in 180 days,” Seth Stern, director of advocacy for the Freedom of the Press Foundation, told Al Jazeera.

    It is not the first time a publication has appointed an editorial board to weigh in on concerns about editorial influence. In 2007, when News Corp acquired Dow Jones, the parent company of the Wall Street Journal, the Bancroft family, which owned the publisher at the time, was concerned that new owner and media mogul Rupert Murdoch would impact the paper’s editorial independence with his conservative tilt.

    The paper appointed a five-person independent committee to preserve editorial integrity. But it was later revealed, including by former members of the board during a roundtable discussion hosted by the Freedom of the Press Foundation, that it did not deliver the oversight that it was originally intended to provide.

    In Skydance’s case, the board is to be made up of five journalists appointed by Ellison, and there is no requirement for the company to disclose its findings to the public. The terms say that no more than two people on the board can be affiliated with the same political party.

    “The truth isn’t dictated by the fifty-yard line between political parties. Sometimes neither political party is even close to the truth. So having a commitment to bipartisan representation, as opposed to a commitment to truth-telling, totally misunderstands what news is,” Stern said.

    On Wall Street, the new company began trading under the ticker symbol SKYD. Since opening on Tuesday, the stock has dropped 2.5 percent.

  • Christa Pike lawyers say she is speaking one week after failed execution

    Christa Pike lawyers say she is speaking one week after failed execution

    The 50-year-old has regained consciousness and is receiving care nearly one week after being sent to the hospital following a botched lethal injection.

    Lawyers for Christa Pike say she is awake and able to speak after her botched execution attempt by the state of Tennessee on September 30.

    Tuesday’s statement marks the first public indication that Pike’s condition has improved after she was transported to a Nashville hospital after receiving two doses of pentobarbitol, lethal injections intended to end her life.

    Her failed execution has sparked debate about the use of the death penalty in the United States. Pike is thought to be the first person to have survived such an injection in the country.

    “Against all odds, Christa Pike is conscious, speaking, and continues to receive critical medical care,” Pike’s lawyers said in a statement.

    “Despite the severe damage she endured to her arms, she is still handcuffed and shackled to the bed. Her recovery is medically unprecedented. Her prognosis remains unclear but, at a minimum, we expect a long recovery.”

    The statement also expresses gratitude to medical workers who the lawyers say have “treated Christa like a human and have provided exceptional care to her”.

    Pike’s lawyers had previously stated that she was unconscious and on a ventilator. They described her arms as “swollen, burned and blistered” by the failed execution.

     

    Pike was convicted and sentenced to die in 1996 for her participation in the murder of a classmate, Colleen Slemmer, when she was 18 years old. Two co-defendants received lesser sentences.

    Pike’s defence lawyers had pointed to her mental health struggles in their attempts to commute her sentence. But the Slemmer family had advocated for the death penalty, pointing to the violent nature of the 19-year-old’s murder.

    Accounts of Pike’s failed execution describe her kicking off the sheet covering her body and, at one point, appearing to snore. She reportedly expressed feeling pain as the lethal injections were administered.

    The incident has brought attention to the prevalence of botched executions in the US criminal justice system.

    Critics have argued that botched executions — defined as those that deviate from established procedures through unforeseen issues, delays or administrative incompetence — can cause unnecessary pain and suffering for those being put to death.

    Citing the researcher Austin Sarat, the Death Penalty Information Center, a nonprofit, estimates that 3 percent of executions in the US from 1890 to 2010 were botched.

  • David Ellison Defends Meeting With Trump Amid  Paramount-Warner Bros Merger Review, Comments On What Was Said About CNN

    David Ellison Defends Meeting With Trump Amid Paramount-Warner Bros Merger Review, Comments On What Was Said About CNN

    Skydance CEO David Ellison defended meeting with Donald Trump as Paramount sought to complete its merger with Warner Bros Discovery, while addressing concerns that he talked to the president about the future of CNN.

    “For absolute clarity, we have not talked to any political leader of any party about news, other than to say that we want to be in the truth business and we want to be in the trust business, and we believe in complete editorial independence,” Ellison told reporters Tuesday at an afternoon press conference on the Paramount lot, hours after its merger with WBD closed.

    At a town hall meeting earlier Tuesday, Ellison said he supported CNN’s legal challenge to Trump’s ban on the network from the White House grounds, with MS NOW and Politico also restricted. A federal judge sidelined that ban at least temporarily, and will hear arguments at a Thursday hearing on the media outlets’ motion for a preliminary injunction.

    Ellison was asked about a comment he made in August 2025, on the date that Skydance’s acquisition of Paramount closed, that he did not want to see that company politicized.

    As it turned out, the Paramount-WBD process became unusually politicized for a media transaction, and Ellison himself met with Trump, including hosting a dinner for his administration in April and attending the UFC match on the White House grounds in June.

    “What I would say is, we have a good relationship with this administration,” Ellison said. “I also had a really good relationship with President Biden. I have a good relationship with Senator Tim Scott, and I have a good relationship with Governor Gavin Newsom. I think it is important to talk to everybody on both sides of the aisle.”

    He added, “When you’re operating within a business-friendly administration, you should always have those relationships,” pointing out that Ari Emanuel and Dana White sat next to the president at the UFC event, as well as tech figures like Tim Cook and Jeff Bezos who have visited the White House and were at the recent state dinner for Chinese President Xi Jinping.

    “We want to speak to everybody. We do not want to politicize the company,” he said. “We were in a transaction review process, but with that said, we are now turning that page. We are operating. We are moving forward, and again, we want to speak to the largest audiences humanly possible. So I understand how some people feel about that. The best thing I can say is we want to prove it over time.”

    Ellison also said that he was in Washington, D.C., to push for a federal tax incentive since October of last year. He said that it was Sen. Lindsey Graham (R-SC) who “actually really shepherded that endeavor,” with multiple meetings with him and Trump. That is “really what got the president to effectively say, ‘Yes, I see this, and yes, I want to support this.’ “

    He said that he and Makan Delrahim, Paramount’s chief legal officer, were in Washington last week to try to get the incentive legislation “done by December 11 and the end of the year.” There are hopes among boosters of the federal incentive that it can be attached to a year-end government funding bill, with the current legislation running out on that date.

    RELATED: Lawmakers Introduce Bill For 20% Federal Film & TV Incentive — Read The Bill

    He added that they have had conversations with both of California’s gubernatorial candidates, Xavier Becerra and Steve Hilton, as well as Attorney General Rob Bonta, “about what could hopefully be done to make California basically more competitive with other states.” Even with the federal rebate, Ellison said, the state would still face competition from New Jersey and Georgia with larger packages of incentives.

    “So if this federal rebate can get done, which can only get done bipartisan, it’s not possible any other way, it should be one of the most significant booms to out film business in this country,” he said.

    “We want to see these lots and our soundstages filled with people making movies and telling stories again, and the only way you can do that is to speak with the elected leaders on both sides of the aisle, including the White House, to hopefully accomplish that goal,” he said.
