An anonymous reader quotes a report from Wired: Two years ago, researchers in the Netherlands discovered an intentional backdoor in an encryption algorithm baked into radios used by critical infrastructure -- as well as police, intelligence agencies, and military forces around the world -- that made any communication secured with the algorithm vulnerable to eavesdropping. When the researchers publicly disclosed the issue in 2023, the European Telecommunications Standards Institute (ETSI), which developed the algorithm, advised anyone using it for sensitive communication to deploy an end-to-end encryption solution on top of the flawed algorithm to bolster the security of their communications. But now the same researchers have found that at least one implementation of the end-to-end encryption solution endorsed by ETSI has a similar issue that makes it equally vulnerable to eavesdropping. The encryption algorithm used for the device they examined starts with a 128-bit key, but this gets compressed to 56 bits before it encrypts traffic, making it easier to crack. It's not clear who is using this implementation of the end-to-end encryption algorithm, nor if anyone using devices with the end-to-end encryption is aware of the security vulnerability in them. Wired notes that the end-to-end encryption the researchers examined is most commonly used by law enforcement and national security teams. "But ETSI's endorsement of the algorithm two years ago to mitigate flaws found in its lower-level encryption algorithm suggests it may be used more widely now than at the time."

ZDNet's Steven Vaughan-Nichols shares his list of "what's new and improved" in the latest Linux 6.16 kernel. An anonymous reader shares an excerpt from the report: First, the Rust language is continuing to become more well-integrated into the kernel. At the top of my list is that the kernel now boasts Rust bindings for the driver core and PCI device subsystem. This approach will make it easier to add new Rust-based hardware drivers to Linux. Additionally, new Rust abstractions have been integrated into the Direct Rendering Manager (DRM), particularly for ioctl handling, file/GEM memory management, and driver/device infrastructure for major GPU vendors, such as AMD, Nvidia, and Intel. These changes should reduce vulnerabilities and optimize graphics performance. This will make gamers and AI/ML developers happier.

Linux 6.16 also brings general improvements to Rust crate support. Crate is Rust's packaging format. This will make it easier to build, maintain, and integrate Rust kernel modules into the kernel. For those of you who still love C, don't worry. The vast majority of kernel code remains in C, and Rust is unlikely to replace C soon. In a decade, we may be telling another story. Beyond Rust, this latest release also comes with several major file system improvements. For starters, the XFS filesystem now supports large atomic writes. This capability means that large multi-block write operations are 'atomic,' meaning all blocks are updated or none. This enhances data integrity and prevents data write errors. This move is significant for companies that use XFS for databases and large-scale storage.

Perhaps the most popular Linux file system, Ext4, is also getting many improvements. These boosts include faster commit paths, large folio support, and atomic multi-fsblock writes for bigalloc filesystems. What these improvements mean, if you're not a file-system nerd, is that we should see speedups of up to 37% for sequential I/O workloads. If your Linux laptop doubles as a music player, another nice new feature is that you can now stream your audio over USB even while the rest of your system is asleep. That capability's been available in Android for a while, but now it's part of mainline Linux.

If security is a top priority for you, the 6.16 kernel now supports Intel Trusted Execution Technology (TXT) and Intel Trusted Domain Extensions (TDX). This addition, along with Linux's improved support for AMD Secure Encrypted Virtualization and Secure Memory Encryption (SEV-SNP), enables you to encrypt your software's memory in what's known as confidential computing. This feature improves cloud security by encrypting a user's virtual machine memory, meaning someone who cracks a cloud can't access your data. Linux 6.16 also delivers several chip-related upgrades. It introduces support for Intel's Advanced Performance Extensions (APX), doubling x86 general-purpose registers from 16 to 32 and boosting performance on next-gen CPUs like Lunar Lake and Granite Rapids Xeon. Additionally, the new CONFIG_X86_NATIVE_CPU option allows users to build processor-optimized kernels for greater efficiency.

Support for Nvidia's AI-focused Blackwell GPUs has also been improved, and updates to TCP/IP with DMABUF help offload networking tasks to GPUs and accelerators. While these changes may go unnoticed by everyday users, high-performance systems will see gains and OpenVPN users may finally experience speeds that challenge WireGuard.

Security researchers have discovered evidence suggesting the SkyRover X1 drone sold on Amazon for some $750 is a DJI product operating under a different brand name. The findings come at a time when DJI is facing an unofficial ban at US customs.

The drone shares identical specifications and features with the DJI Mini 4 Pro and connects to DJI's online infrastructure, including DJIGlobal, DJISupport, and DJIEnterprise services.

Hacker Kevin Finisterre successfully logged into the SkyRover system using his existing DJI credentials. Security consultant Jon Sawyer found the SkyRover app uses the same encryption keys as DJI software, with the company making only basic attempts to conceal its origins by replacing "DJI" references with "xxx" or "uav." DJI didn't deny to The Verge that the SkyRover X1 is their product.

Sir Keir Starmer's government is seeking a way out of a clash with the Trump administration over the UK's demand that Apple provide it with access to secure customer data, Financial Times reported Monday, citing two officials. From the report: The officials both said the Home Office, which ordered the tech giant in January to grant access to its most secure cloud storage system, would probably have to retreat in the face of pressure from senior leaders in Washington, including Vice President JD Vance.

"This is something that the vice president is very annoyed about and which needs to be resolved," said an official in the UK's technology department. "The Home Office is basically going to have to back down." Both officials said the UK decision to force Apple to break its end-to-end encryption -- which has been raised multiple times by top officials in Donald Trump's administration -- could impede technology agreements with the US.

Brian Witten, VP/CSO of automotive technology supplier Aptiv, warns that "While seven to 10 years may sound like a long way off, preparation for quantum threats must begin now, not once they have already materialized." Organizations need time to implement post-quantum cryptography (PQC) transition plans methodically — and that applies both to anyone with an IT infrastructure and to anyone building software-defined systems. "Current encryption, such as RSA and ECC [elliptic curve cryptography], will become obsolete once quantum computing matures," said Cigent cofounder John Benkert. "Management often assumes cybersecurity threats are only present-day problems. But this is a future-proofing issue — especially relevant for industries dealing with sensitive, long-lifespan data, like healthcare, finance or government." Remediation requires long-term planning. Organizations that wait until quantum computers have broken encryption to address the threat will find that it is too late.
Start by building an inventory of what needs to change, Witten recommends. (Fortunately, "It's a matter of using newer and different chips and algorithms, not necessarily more expensive components," he writes, also suggesting requests for proposals "should ask vendors to include a PQC update plan.")

Firmware will also need quantum-resistant digital signatures. ("Broken authentication lets bad things happen. Someone could remotely take over a vehicle, for instance, or send malicious code for autonomous execution later, even after the vehicle has gone offline.") And remember that post-quantum key sizes are larger, requiring more storage space. "In some cases, digitally signed messages with security information could triple in size, which could impact storage and bandwidth."

An anonymous reader quotes a report from TechCrunch: On Sunday, Block CEO and Twitter co-founder Jack Dorsey launched an open source chat app called Bitchat, promising to deliver "secure" and "private" messaging without a centralized infrastructure. The app relies on Bluetooth and end-to-end encryption, unlike traditional messaging apps that rely on the internet. By being decentralized, Bitchat has potential for being a secure app in high-risk environments where the internet is monitored or inaccessible. According to Dorsey's white paper detailing the app's protocols and privacy mechanisms, Bitchat's system design "prioritizes" security.

But the claims that the app is secure, however, are already facing scrutiny by security researchers, given that the app and its code have not been reviewed or tested for security issues at all -- by Dorsey's own admission. Since launching, Dorsey has added a warning to Bitchat's GitHub page: "This software has not received external security review and may contain vulnerabilities and does not necessarily meet its stated security goals. Do not use it for production use, and do not rely on its security whatsoever until it has been reviewed." This warning now also appears on Bitchat's main GitHub project page but was not there at the time the app debuted.

As of Wednesday, Dorsey added: "Work in progress," next to the warning on GitHub. This latest disclaimer came after security researcher Alex Radocea found that it's possible to impersonate someone else and trick a person's contacts into thinking they are talking to the legitimate contact, as the researcher explained in a blog post. Radocea wrote that Bitchat has a "broken identity authentication/verification" system that allows an attacker to intercept someone's "identity key" and "peer id pair" -- essentially a digital handshake that is supposed to establish a trusted connection between two people using the app. Bitchat calls these "Favorite" contacts and marks them with a star icon. The goal of this feature is to allow two Bitchat users to interact, knowing that they are talking to the same person they talked to before.

Jack Dorsey has launched Bitchat, a decentralized, peer-to-peer messaging app that uses Bluetooth mesh networks for encrypted, ephemeral chats without requiring accounts, servers, or internet access. The beta version is live on TestFlight, with a full white paper available on GitHub. CNBC reports: In a post on X Sunday, Dorsey called it a personal experiment in "bluetooth mesh networks, relays and store and forward models, message encryption models, and a few other things."

Bitchat enables ephemeral, encrypted communication between nearby devices. As users move through physical space, their phones form local Bluetooth clusters and pass messages from device to device, allowing them to reach peers beyond standard range -- even without Wi-Fi or cell service. Certain "bridge" devices connect overlapping clusters, expanding the mesh across greater distances. Messages are stored only on device, disappear by default and never touch centralized infrastructure -- echoing Dorsey's long-running push for privacy-preserving, censorship-resistant communication.

Like the Bluetooth-based apps used during Hong Kong's 2019 protests, Bitchat is designed to keep working even when the internet is blocked, offering a censorship-resistant way to stay connected during outages, shutdowns or surveillance. The app also supports optional group chats, or "rooms," which can be named with hashtags and protected by passwords. It includes store and forward functionality to deliver messages to users who are temporarily offline. A future update will add WiFi Direct to increase speed and range, pushing Dorsey's vision for off-grid, user-owned communication even further.

Two accessory manufacturers have told The Verge that Nintendo has intentionally locked down the Switch 2's USB-C port using a new encryption scheme, preventing compatibility with third-party docks and accessories. "I haven't yet found proof of that encryption chip myself -- but when I analyzed the USB-C PD traffic with a Power-Z tester, I could clearly see the new Nintendo Switch not behaving like a good USB citizen should," writes The Verge's Sean Hollister. From the report: If you've been wondering why there are basically no portable Switch 2 docks on the market, this is the reason. Even Jsaux, the company that built its reputation by beating the Steam Deck dock to market, tells us it's paused its plans to build a Switch 2 dock because of Nintendo's actions. It's not simply because the Switch 2 now requires more voltage, as was previously reported; it's that Nintendo has made things even more difficult this generation.

Psylo, a new privacy-focused iOS browser by Mysk, aims to defeat digital fingerprinting by isolating each browser tab with its own IP address, unique fingerprinting defenses, and proxy-based encryption. "Psylo stands out as it is the only WebKit-based iOS browser that truly isolates tabs," Tommy Mysk told The Register. "It's not only about separate storage and cookies. Psylo goes beyond that."

"This is why we call tabs 'silos.' It applies unique anti-fingerprinting measures per silo, such as canvas randomization. This way two Psylo tabs opening the same website would appear as though they originated on two different devices to the opened website." From the report: The company claims Psylo therefore offers better privacy than a VPN because the virtual networks mask the user's IP address but generally don't alter the data used for fingerprinting. Psylo, for example, will adjust the browser's time zone and browser language to match the geolocation of each proxy, resulting in more entropy that means fingerprints created by gathering data from silos will appear to be different.

The Mysk devs' post states that some privacy-focused browsers like Brave also implement anti-fingerprinting measures like canvas randomization, but those are more effective on the desktop macOS app due to Apple's iOS restrictions. They claim that they were able to achieve better results on iOS by using a client-side JavaScript solution. Mysk designed Psylo to minimize the information available to its maker. It doesn't log personally identifiable information or browsing data that the curious could use to identify the user, the company claims, noting that it also doesn't have customer payment information, which is handled by Apple. There are no user accounts, only randomized identifiers to indicate active subscriptions. According to Tommy Mysk, the only subscriber data kept is bandwidth usage, which is necessary to prevent abuse.

"We aggregate bandwidth usage based on a randomly generated ID that is created when a subscription is made," Mysk said. "The randomly generated ID is associated with the Apple subscription transaction. Apple doesn't share the identity of users making App Store purchases with developers." Asked whether Apple could identify users, Mysk said, "Theoretically and given a court order, Apple can figure out the randomly generated ID of the user in question. If we were to hand out the data associated with the randomly generated ID, it would only be the bandwidth usage of that user in the current month, and two months in the past. Older data is automatically deleted. "We don't associate any identifiable information with the randomly generated ID. We don't store IP addresses at all in every component of our system. We don't store websites visited by our users at all." The browser is only available on iOS and iPadOS, but Mysk says an Android version could be developed if there's enough interest. It costs $9.99 per month or $99 per year in the U.S.

Western Digital has succeeded in having the sum it owed from a patent infringement case reduced from $553 million down to just $1 in post-trial motions, when the judge found the plaintiff's claims had shifted during the course of the litigation. From a report: The storage biz was held by a California jury to have infringed on data encryption patents owned by SPEX Technologies Inc in October, relating to several of its self-encrypting hard drive products.

WD was initially told to pay $316 million in damages, but District Judge James Selna ruled the company owed a further $237 million in interest charges earlier this year, bringing the total to more than half a billion dollars. In February, WD was given a week to file a bond or stump up the entire damages payment. Selna granted Western Digital's post-trial motion to reduce damages, writing that "SPEX's damages theory changed as certain evidence and theories became unavailable" and there was "insufficient evidence from which the Court could determine a reasonable royalty."

The U.S. House chief administrative officer has banned WhatsApp from congressional staffers' government devices citing data vulnerability concerns. The cybersecurity office deemed the messaging app "high-risk" due to lack of transparency in data protection, absence of stored data encryption, and potential security risks, according to an email obtained by Axios.

Staff cannot download or keep WhatsApp on any House device, including mobile, desktop, or web browser versions.

Iranian state television has instructed residents to delete WhatsApp from their smartphones, claiming the messaging platform gathers user information to share with Israel.

The local media provided no evidence supporting these allegations but additionally encouraged residents to avoid other "location-based" apps. WhatsApp has disputed the claims, with a spokesperson telling Time magazine the Meta-owned platform uses end-to-end encryption and does not track precise locations, keep messaging logs, or provide bulk information to governments.

The episode comes at a time when Iran is simultaneously experiencing a "near-total national Internet blackout," according to NetBlock, an internet governance monitoring organization. The disruption follows earlier partial outages amid escalating military tensions with Israel after days of missile strikes between the countries.

Austria's coalition government has agreed on a plan to enable police to monitor suspects' secure messaging in order to thwart militant attacks, ending what security officials have said is a rare and dangerous blind spot for a European Union country. From a report: Because Austria lacks a legal framework for monitoring messaging services like WhatsApp, its main domestic intelligence service and police rely on allies with far more sweeping powers like Britain and the United States alerting them to chatter about planned attacks and spying.

That kind of tip-off led to police unravelling what they say was a planned attack on a Taylor Swift concert in Vienna, which prompted the cancellation of all three of her planned shows there in August of last year. "The aim is to make people planning terrorist attacks in Austria feel less secure - and increase everyone else's sense of security," Joerg Leichtfried of the Social Democrats, the junior minister in charge of overseeing the Directorate for State Security and Intelligence (DSN), told a news conference.

Researchers have built a breakthrough random number generator that solves a critical problem: for the first time, every step of creating random numbers can be independently verified and audited, with quantum physics guaranteeing the numbers were truly unpredictable.

Random numbers are essential for everything from online banking encryption to fair lottery drawings, but current systems have serious limitations. Computer-based generators follow predictable algorithms -- if someone discovers the starting conditions, they can predict all future outputs. Hardware generators that measure physical processes like electronic noise can't prove their randomness wasn't somehow predetermined or tampered with.

The new system, developed by teams at the University of Colorado Boulder and the National Institute of Standards and Technology, uses quantum entanglement -- Einstein's "spooky action at a distance" -- to guarantee unpredictability. The setup creates pairs of photons that share quantum properties, then sends them to measurement stations 110 meters apart. When researchers measure each photon's properties, quantum mechanics ensures the results are fundamentally random and cannot be influenced by any classical communication between the stations.

The team created a system called "Twine" that distributes the random number generation process across multiple independent parties, with each step recorded in tamper-proof digital ledgers called hash chains. This means no single organization controls the entire process, and anyone can verify that proper procedures were followed. During a 40-day demonstration, the system successfully generated random numbers in 7,434 of 7,454 attempts -- a 99.7% success rate. Each successful run produced 512 random bits with mathematical certainty of randomness bounded by an error rate of 2^-64, an extraordinarily high level of confidence.

An anonymous reader shares a report: When Facebook bought WhatsApp for $19 billion in 2014, the messaging app had a clear focus. No ads, no games and no gimmicks. For years, that is what WhatsApp's two billion users -- many of them in Brazil, India and other countries around the world -- got. They chatted with friends and family unencumbered by advertising and other features found on social media. Now that is set to change.

On Monday, WhatsApp said it would start showing ads inside its app for the first time. The promotions will appear only in an area of the app called Updates, which is used by around 1.5 billion people a day. WhatsApp will collect some data on users to target the ads, such as location and the device's default language, but it will not touch the contents of messages or whom users speak with. The company added that it had no plans to place ads in chats and personal messages.

[...] In-app ads are a significant change from WhatsApp's original philosophy. Jan Koum and Brian Acton, who founded WhatsApp in 2009, were committed to building a simple and quick way for friends and family to communicate with end-to-end encryption, a method of keeping texts, photos, videos and phone calls inaccessible by third parties. Both left the company seven years ago. Since then, Mark Zuckerberg, the chief executive of Facebook, now Meta, has focused on WhatsApp's growth and user privacy while also melding the app into the company's other products, including Instagram and Messenger.

WhatsApp has applied to submit evidence in Apple's legal battle against the UK Home Office over government demands for access to encrypted user data. The messaging platform's boss Will Cathcart told the BBC the case "could set a dangerous precedent" by "emboldening other nations" to seek to break encryption protections.

The confrontation began when Apple received a secret Technical Capability Notice from the Home Office earlier this year demanding the right to access data from its global customers for national security purposes. Apple responded by first pulling its Advanced Data Protection system from the UK, then taking the government to court to overturn the request.

Cathcart said WhatsApp "would challenge any law or government request that seeks to weaken the encryption of our services." US Director of National Intelligence Tulsi Gabbard has called the UK's demands an "egregious violation" of American citizens' privacy rights.

An anonymous reader quotes a report from Axios: President Trump quietly took a red pen to much of the Biden administration's cyber legacy in a little-noticed move late Friday. Under an executive order signed just before the weekend, Trump is tossing out some of the major touchstones of Biden's cyber policy legacy -- while keeping a few others. The order preserves efforts around post-quantum cryptography, advanced encryption standards, and border gateway protocol security, along with the Cyber Trust Mark program -- an Energy Star-type labeling initiative for consumer smart devices. But hallmark programs tied to software bills of materials, zero-trust implementation, and space contractor cybersecurity requirements have been either rescinded or left in limbo. The new executive order amends both the Biden cyber executive order signed in January and an Obama administration order.

Each of the following Biden-era programs is now out the door or significantly rolled back:
- A broad requirement for federal software vendors to provide a software bill of materials - essentially an ingredient list of code components - is gone.
- Biden-era efforts to encourage federal agencies to accept digital identity documents and help states develop mobile driver's licenses were revoked.
- Several AI cybersecurity research mandates, including those focused on AI-generated code security and AI-driven patch management pilots, have been scrapped or deprioritized.
- The requirement that software contractors formally attest they followed secure development practices - and submit those attestations to a federal repository - has been cut. Instead, the National Institute of Standards and Technology will now coordinate a new industry consortium to review software security guidelines.

An anonymous reader shares a blog post from Google: Today, we're bringing you Android 16, rolling out first to supported Pixel devices with more phone brands to come later this year. This is the earliest Android has launched a major release in the last few years, which ensures you get the latest updates as soon as possible on your devices. Android 16 lays the foundation for our new Material 3 Expressive design, with features that make Android more accessible and easy to use.

An anonymous reader shared this report from The New York Times: Russian counterintelligence agents are analyzing data from the popular Chinese messaging and social media app WeChat to monitor people who might be in contact with Chinese spies, according to a Russian intelligence document obtained by The New York Times. The disclosure highlights the rising level of concern about Chinese influence in Russia as the two countries deepen their relationship. As Russia has become isolated from the West over its war in Ukraine, it has become increasingly reliant on Chinese money, companies and technology. But it has also faced what the document describes as increased Chinese espionage efforts.

The document indicates that the Russian domestic security agency, known as the F.S.B., pulls purloined data into an analytical tool known as "Skopishche" (a Russian word for a mob of people). Information from WeChat is among the data being analyzed, according to the document... One Western intelligence agency told The Times that the information in the document was consistent with what it knew about "Russian penetration of Chinese communications...." By design, [WeChat] does not use end-to-end encryption to protect user data. That is because the Chinese government exercises strict control over the app and relies on its weak security to monitor and censor speech. Foreign intelligence agencies can exploit that weakness, too...

WeChat was briefly banned in Russia in 2017, but access was restored after Tencent took steps to comply with laws requiring foreign digital platforms above a certain size to register as "organizers of information dissemination." The Times confirmed that WeChat is currently licensed by the government to operate in Russia. That license would require Tencent to store user data on Russian servers and to provide access to security agencies upon request.

FFmpeg has added support for WHIP (WebRTC-HTTP Ingestion Protocol), enabling sub-second latency live streaming by leveraging WebRTC's fast, secure video delivery capabilities. It's a major update that introduces a new WHIP muxer to make FFmpeg more powerful for real-time broadcasting applications. Phoronix's Michael Larabel reports: WHIP uses HTTP for exchanging initial information and capabilities and then uses STUN binding to establish a UDP session. Encryption is supported -- and due to WebRTC, mandatory -- with WHIP and audio/video frames are split into RTP packets. WebRTC-HTTP Ingestion Protocol is an IETF standard for ushering low-latency communication over WebRTC to help with streaming/broadcasting uses. With this FFmpeg commit introducing nearly three thousand lines of new code, an initial WHIP muxer has been introduced. You can learn more about WebRTC WHIP in this presentation by Millicast (PDF).
