Sunbird, the app that brings iMessage to Android, has temporarily shut down the service over “security concerns.” From a report: In a notice to users, Sunbird says it has “decided to pause Sunbird usage for now” while it investigates reports that its messages aren’t actually end-to-end encrypted. Sunbird launched in 2022 as a messaging app that attempts to put the blue versus green bubble battle to rest. It has only been available to those who sign up for its waitlist, touting numerous privacy features, like end-to-end encryption, no message data collection, and no ads.

Last week, Sunbird partnered with Nothing, the phone brand owned by OnePlus co-founder Carl Pei, on the launch of Nothing Chats. The Sunbird-powered messaging service is supposed to let owners of the Phone 2 send texts via iMessage, but it was pulled from the Google Play Store just one day after its launch. At the time, Nothing said it had to fix “several bugs” within the app. However, its removal from the Play Store came around the same time a post from Texts.blog revealed that messages sent via Sunbird may not be end-to-end encrypted.

An anonymous reader shares a report: Firefox users across the internet say that they are encountering an “artificial” five-second load time when they try to watch YouTube videos that exists on Firefox, but not Chrome. Google, meanwhile, told 404 Media that this is all part of its larger effort against ad blockers, and that it doesn’t have anything to do with Firefox at all. […] Mozilla, which makes Firefox, told 404 Media that it does not believe this is a Firefox-specific issue. Enough people have posted about it, however, that it is clearly happening for some users and not others.

In a statement to 404 Media, Google did not provide specifics but also did not deny implementing an artificial wait time. “To support a diverse ecosystem of creators globally and allow billions to access their favorite content on YouTube, we’ve launched an effort to urge viewers with ad blockers enabled to allow ads on YouTube or try YouTube Premium for an ad free experience, the spokesperson said. “Users who have ad blockers installed may experience suboptimal viewing, regardless of the browser they are using.”

Epic Games Chief Executive Officer Tim Sweeney testified that Google’s Android operating system is a “fake open platform” in a high-stakes antitrust lawsuit over claims that the technology giant thwarts app market competition. From a report: Sweeney, who founded the company that makes the blockbuster Fortnite, took the witness stand Monday in San Francisco federal court to reinforce his claims that Google Play policies are unlawful and allow Alphabet to maintain a monopoly in the Android mobile-app distribution market. The court fight started in 2020 when Epic marketed Fortnite on Android and sidestepped the Google Play billing system and the 30% revenue cut it was taking from app developers.

“We very much wanted to avoid that and do business directly with our customers,” Sweeney told jurors. Google denies abusing its market power. The jury trial started two weeks ago and is expected to wrap up in early December. If Epic prevails, Google could be forced to allow competing app marketplaces and payment methods on its app store, threatening billions of dollars in revenue generated by Google Play. Sweeney previously testified in a 2021 trial in a similar antitrust suit targeting Apple’s App Store policies as unfair and self-serving. Epic mostly lost that fight, which was decided by a federal judge in Oakland, California, after a trial. An appeals court upheld the judge’s ruling and Epic is now asking the US Supreme Court to review it.

An anonymous reader quotes a report from The Verge: Music streaming service Spotify struck a seemingly unique and highly generous deal with Google for Android-based payments, according to new testimony in the Epic v. Google trial. On the stand, Google head of global partnerships Don Harrison confirmed Spotify paid a 0 percent commission when users chose to buy subscriptions through Spotify’s own system. If the users picked Google as their payment processor, Spotify handed over 4 percent — dramatically less than Google’s more common 15 percent fee. Google fought to keep the Spotify numbers private during its antitrust fight with Epic, saying they could damage negotiations with other app developers who might want more generous rates.

Google’s User Choice Billing program, launched in 2022, is typically described as shaving about 4 percent off Google’s Play Store commission if developers use their own payment system, bringing down Google’s 15 percent subscription service fee to more like 11 percent. That often ends up saving developers little or no money since they must foot the cost of payment processing themselves. And in court, Google has focused on benefits like greater flexibility rather than cost savings. […] Harrison says Spotify’s “unprecedented” popularity was great enough to justify a “bespoke” deal. “If we don’t have Spotify working properly across Play services and core services, people will not buy Android phones,” Harrison testified. As part of the deal, both parties also agreed to commit $50 million apiece to a “success fund.”

Google acknowledged Harrison’s testimony in a statement to The Verge. “A small number of developers that invest more directly in Android and Play may have different service fees as part of a broader partnership that includes substantial financial investments and product integrations across different form factors,” says spokesperson Dan Jackson. “These key investment partnerships allow us to bring more users to Android and Play by continuously improving the experience for all users and create new opportunities for all developers.” Google would not name other developers that have gotten the company to agree to more generous rates. During the trial, we learned that Google offered Netflix a special discounted rate of just 10 percent, but Netflix refused. Netflix no longer offers an in-app purchase option on Android and no longer pays Google anything to distribute its app as a result.

The U.S. Food and Drug Administration is reviewing a cutting-edge therapy called exa-cel that could potentially cure people of sickle cell disease, a painful and deadly disease with no universally successful treatment. “If approved, exa-cel, made by Boston-based Vertex Pharmaceuticals and the Swiss company CRISPR Therapeutics, would be the first FDA-approved treatment that uses genetic modification called CRISPR,” reports CNN. From the report: CRISPR, or clustered regularly interspaced short palindromic repeats, is a technology researchers use to selectively modify DNA, the carrier of genetic information that the body uses to function and develop. […] The new exa-cel treatment under FDA consideration can use the patient’s own stem cells. Doctors would alter them with CRISPR to fix the genetic problems that cause sickle cell, and then the altered stem cells are given back to the patient in a one-time infusion.

In company studies, the treatment was considered safe, and it had a “highly positive benefit-risk for patients with severe sickle cell disease,” Dr. Stephanie Krogmeier, vice president for global regulatory affairs with Vertex Pharmaceuticals Incorporated, told the panel. Thirty-nine of the 40 people tested with the treatment did not have a single vaso-occlusive crisis, which means the misshapen red blood cells block normal circulation and can cause moderate to severe pain. It’s the top reason patients with sickle cell go to the emergency room or are hospitalized. Before the treatment, patients experienced about four of these painful crises a year, resulting in about two weeks in the hospital.

The FDA sought the independent panel’s advice, in part, because this would be the first time the FDA would approve a treatment that uses CRISPR technology, but Dr. Fyodor Urnov, a professor in the Department of Molecular and Cell Biology at the University of California, Berkeley, reminded the committee CRISPR has been around for 30 years and, in that time, scientists have learned a lot about how to use it safely. “The technology is, in fact, ready for primetime,” Urnov said. With this kind of genetic editing, scientists could inadvertently make a change to a patient’s DNA that is off-target, and the therapy could harm the patient. […] The FDA is expected to make an approval decision by December 8.

An anonymous reader quotes a report from Wired: A little-known surveillance program tracks more than a trillion domestic phone records within the United States each year, according to a letter WIRED obtained that was sent by US senator Ron Wyden to the Department of Justice (DOJ) on Sunday, challenging the program’s legality. According to the letter, a surveillance program now known as Data Analytical Services (DAS) has for more than a decade allowed federal, state, and local law enforcement agencies to mine the details of Americans’ calls, analyzing the phone records of countless people who are not suspected of any crime, including victims. Using a technique known as chain analysis, the program targets not only those in direct phone contact with a criminal suspect but anyone with whom those individuals have been in contact as well.

The DAS program, formerly known as Hemisphere, is run in coordination with the telecom giant AT&T, which captures and conducts analysis of US call records for law enforcement agencies, from local police and sheriffs’ departments to US customs offices and postal inspectors across the country, according to a White House memo reviewed by WIRED. Records show that the White House has, for the past decade, provided more than $6 million to the program, which allows the targeting of the records of any calls that use AT&T’s infrastructure — a maze of routers and switches that crisscross the United States. In a letter to US attorney general Merrick Garland on Sunday, Wyden wrote that he had “serious concerns about the legality” of the DAS program, adding that “troubling information” he’d received “would justifiably outrage many Americans and other members of Congress.” That information, which Wyden says the DOJ confidentially provided to him, is considered “sensitive but unclassified” by the US government, meaning that while it poses no risk to national security, federal officials, like Wyden, are forbidden from disclosing it to the public, according to the senator’s letter. AT&T spokesperson Kim Hart Jonson said only that the company is required by law to comply with a lawful subpoena. However, “there is no law requiring AT&T to store decades’ worth of Americans’ call records for law enforcement purposes,” notes Wired. “Documents reviewed by WIRED show that AT&T officials have attended law enforcement conferences in Texas as recently as 2018 to train police officials on how best to utilize AT&T’s voluntary, albeit revenue-generating, assistance.”

“The collection of call record data under DAS is not wiretapping, which on US soil requires a warrant based on probable cause. Call records stored by AT&T do not include recordings of any conversations. Instead, the records include a range of identifying information, such as the caller and recipient’s names, phone numbers, and the dates and times they placed calls, for six months or more at a time.” It’s unclear exactly how far back the call records accessible under DAS go, although a slide deck released under the Freedom of Information Act in 2014 states that they can be queried for up to 10 years.

Earlier this month, the entire Optus mobile network went offline nationwide following a “routine software upgrade.” According to Reuters, “More than 10 million Australians were hit by the 12-hour network blackout […], triggering fury and frustration among customers and raising wider concerns about the telecommunications infrastructure.” Now, according to the Australian Broadcasting Corporation, Optus CEO Kelly Bayer Rosmarin has resigned in the wake of the outage. From the report: She said it “had been an honour to serve” but that “now was an appropriate time to step down.” During Friday’s Senate hearing into the outage, Ms Bayer Rosmarin rebuffed suggestions she was under pressure to step down. “On Friday, I had the opportunity to appear before the Senate to expand on the cause of the network outage and how Optus recovered and responded,” she said in a statement on Monday. “I was also able to communicate Optus’s commitment to restore trust and continue to serve customers. Having now had time for some personal reflection, I have come to the decision that my resignation is in the best interest of Optus moving forward.”

Ms Bayer Rosmarin will be replaced in the interim by chief financial officer Michael Venter. Yuen Kuan Moon, the chief executive of Optus’s Singaporean parent company Singtel Group, said the company understood her decision to resign. Mr Yuen said Singtel recognised “the need for Optus to regain customer trust and confidence as the team works through the impact and consequences of the recent outage and continues to improve.” He said Optus’s priority was about “setting on a path of renewal for the benefit of the community and customers.” Singtel said Optus had also created a new chief operating officer position, which would be carried out by former Optus Business Managing Director Peter Kaliaropoulos.

Last week, Android smartphone manufacturer “Nothing” announced that it’s bringing iMessage to its newest phone through a new “Nothing Chats” app powered by the messaging platform Sunbird. After launching Friday, the app was shut down within 24 hours and the Sunbird app, which Nothing Chat is a clone of, was put “on pause.” The reason? It’s a security nightmare. Ars Technica reports: The initial sales pitch for this app — that it would log you into iMessage on Android if you handed over your Apple username and password — was a huge security red flag that meant Sunbird would need an ultra-secure infrastructure to avoid disaster. Instead, the app turned out to be about as unsecure as you could possibly be. Here’s Nothing’s statement: “We’ve removed the Nothing Chats beta from the Play Store and will be delaying the launch until further notice to work with Sunbird to fix several bugs. We apologize for the delay and will do right by our users.”

How bad are the security issues? Both 9to5Google and Text.com (which is owned by Automattic, the company behind WordPress) uncovered shockingly bad security practices. Not only was the app not end-to-end encrypted, as claimed numerous times by Nothing and Sunbird, but Sunbird actually logged and stored messages in plain text on both the error reporting software Sentry and in a Firebase store. Authentication tokens were sent over unencrypted HTTP so this token could be intercepted and used to read your messages. […]

Despite being the cause of this huge catastrophe, Sunbird has been bizarrely quiet during this whole mess. The app’s X (formerly Twitter) page still doesn’t say anything about the shutdown of Nothing Chats or Sunbird. Maybe that’s for the best because some of Sunbird’s early responses to the security concerns raised on Friday do not seem like they came from a competent developer. […] Nothing has always seemed like an Android manufacturer that was more hype than substance, but we can now add “negligent” to that list. The company latched on to Sunbird, reskinned its app, created a promo website and YouTube video, and coordinated a media release with popular YouTubers, all without doing the slightest bit of due diligence on Sunbird’s apps or its security claims. It’s unbelievable that these two companies made it this far — the launch of Nothing Chats required a systemic security failure across two entire companies.

In an interview with CNBC’s Jon Fortt today, Microsoft CEO Satya Nadella said that the governance structure of OpenAI needs to change after the AI company’s sudden firing of CEO Sam Altman. “At this point, I think it’s very clear that something has to change around the governance,” Nadella said. He added that Microsoft would have “a good dialogue with their board on that.”

Unlike traditional private company boards, OpenAI’s board consists mostly of outsiders and isn’t tasked with maximizing shareholder value. “[N]one of them hold equity in OpenAI,” notes The Verge. “Instead, their stated mission is to ensure the creation of ‘broadly beneficial’ artificial general intelligence, or AGI.” From the report: In his first press interview since Altman’s ouster, Nadella dismissed concerns of long-term damage at OpenAI and said that the critical artificial intelligence research continues as does the partnership with Microsoft. But his comments didn’t clear up confusion surrounding where Altman and fellow OpenAI co-founder Greg Brockman, who was the company’s chairman, will ultimately end up. Early Monday morning Nadella said that Altman, Brockman and their colleagues would join Microsoft as part of a new AI research group. That post followed news that ex-Twitch CEO Emmett Shear had been named OpenAI interim head as Altman looked to depart. Over the course of Monday, it became less evident that Altman and Brockman would actually be joining Microsoft.

Hundreds of OpenAI employees signed a letter to the company’s board demanding that they resign or else the staffers may choose to leave and join their former boss at Microsoft. Nadella said it’s the choice of OpenAI employees whether they stay in their current roles or move to Microsoft, adding that his company has what it needs to keep innovating on its own. “I’m open to both options,” he said. Nadella told Fortt that Microsoft respects OpenAI’s nonprofit roots and shares its belief that AI needs to be developed and rolled out in a safe manner. “We want to make sure that we’re dealing with not only the benefits of technology, but the unintended consequences of the technology from day one, as opposed to waiting for things to happen,” Nadella said. Stay tuned: Legendary tech journalist Kara Swisher is releasing a 30 minute interview with Nadella in which he says, among other things, that he felt he should have been informed earlier as a partner of OpenAI and that will change in the future. “Also lots of deets about new hire [Sam Altman], safety in AGI and even India’s loss to Australia in that cricket match,” says Swisher in a post on X.

Further reading: Some investors in OpenAI are considering suing the board. “Sources said investors are working with legal advisors to study their options,” reports Reuters. “Investors worry that they could lose hundreds of millions of dollars they invested in OpenAI, a crown jewel in some of their portfolios, with the potential collapse of the hottest startup in the rapidly growing generative AI sector.”

An anonymous reader quotes a report from Motherboard: Commercial air crews are reporting something “unthinkable” in the skies above the Middle East: novel “spoofing” attacks have caused navigation systems to fail in dozens of incidents since September. In late September, multiple commercial flights near Iran went astray after navigation systems went blind. The planes first received spoofed GPS signals, meaning signals designed to fool planes’ systems into thinking they are flying miles away from their real location. One of the aircraft almost flew into Iranian airspace without permission. Since then, air crews discussing the problem online have said it’s only gotten worse, and experts are racing to establish who is behind it.

OPSGROUP, an international group of pilots and flight technicians, sounded the alarm about the incidents in September and began to collect data to share with its members and the public. According to OPSGROUP, multiple commercial aircraft in the Middle Eastern region have lost the ability to navigate after receiving spoofed navigation signals for months. And it’s not just GPS — fallback navigation systems are also corrupted, resulting in total failure. According to OPSGROUP, the activity is centered in three regions: Baghdad, Cairo, and Tel Aviv. The group has tracked more than 50 incidents in the last five weeks, the group said in a November update, and identified three new and distinct kinds of navigation spoofing incidents, with two arising since the initial reports in September.

While GPS spoofing is not new, the specific vector of these new attacks was previously “unthinkable,” according to OPSGROUP, which described them as exposing a “fundamental flaw in avionics design.” The spoofing corrupts the Inertial Reference System, a piece of equipment often described as the “brain” of an aircraft that uses gyroscopes, accelerometers, and other tech to help planes navigate. One expert Motherboard spoke to said this was “highly significant.” “This immediately sounds unthinkable,” OPSGROUP said in its public post about the incidents. “The IRS (Inertial Reference System) should be a standalone system, unable to be spoofed. The idea that we could lose all on-board nav capability, and have to ask [air traffic control] for our position and request a heading, makes little sense at first glance” especially for state of the art aircraft with the latest avionics. However, multiple reports confirm that this has happened.” […] There is currently no solution to this problem, with its potentially disastrous effects and unclear cause. According to OPSGROUP’s November update, “The industry has been slow to come to terms with the issue, leaving flight crews alone to find ways of detecting and mitigating GPS spoofing.” If air crews do realize that something is amiss, Humphreys said, their only recourse is to depend on air traffic control.

According to Bloomberg’s Mark Gurman, Apple plans to ditch Qualcomm and build its own custom modem that could launch around 2026. MacRumors reports: Writing in his latest Power On newsletter, Gurman says that Apple’s custom technology aspirations include integrating an in-house modem into its system-on-a-chip (SoC), which would eventually see the launch of MacBooks with built-in cellular connectivity. Gurman says Apple will “probably need two or three additional years to get that chip inside cellular versions of the Apple Watch and iPad — and the Mac, once the part is integrated into the company’s system-on-a-chip.”

Apple has explored the possibility of developing MacBooks with cellular connectivity in the past. Indeed, the company reportedly considered launching a MacBook Air with 3G connectivity, but former CEO Steve Jobs said in 2008 that Apple decided against it, since it would take up too much room in the case. An integrated SoC would solve that problem. Gurman’s latest newsletter also said some of Apple’s other ongoing in-house chip projects include camera sensors, batteries, a combined Wi-Fi and Bluetooth chip that will eventually replace parts from Broadcom, Micro-LED displays for Apple devices, and a non-invasive glucose monitoring system.

An anonymous reader quotes a report from Reuters: Apple has been sued by Venmo and Cash App customers in a proposed class action claiming the iPhone maker abused its market power to curb competition for mobile peer-to-peer payments, causing consumers to pay “rapidly inflating prices.” Four consumers in New York, Hawaii, South Carolina and Georgia filed the lawsuit (PDF) on Friday in San Jose, California, federal court. They alleged Apple violated U.S. antitrust law through its agreements with PayPal’s Venmo and Block’s Cash App.

Apple’s agreements limit “feature competition” within peer-to-peer payment apps, including prohibiting existing or new platforms from using “decentralized cryptocurrency technology,” the complaint said. The lawsuit seeks an injunction that could force Apple to divest or segregate its Apple Cash business.

The use of environmentally damaging gases in air conditioners and refrigerators could become redundant if a new kind of heat pump lives up to its promise. A prototype, described in a study published last week in Science, uses electric fields and a special ceramic instead of alternately vaporizing a refrigerant fluid and condensing it with a compressor to warm or cool air. From a report: The technology combines a number of existing techniques and has “superlative performance,” says Neil Mathur, a materials scientist at the University of Cambridge, UK. Emmanuel Defay, a materials scientist at the Luxembourg Institute of Science and Technology in Belvaux, and his collaborators built their experimental device out of a ceramic with a strong electrocaloric effect. Materials that exhibit this effect heat up when exposed to electric fields.

In an electrocaloric material, the atoms have an electric polarization — a slight imbalance in their distribution of electrons, which gives these atoms a ‘plus’ and a ‘minus’ pole. When the material is left alone, the polarization of these atoms continuously swivels around in random directions. But when the material is exposed to an electric field, all the electrostatic poles suddenly align, like hair combed in one direction. This transition from disorder to order means that the electrons’ entropy — physicists’ way of measuring disorder — suddenly drops, Defay explains. But the laws of thermodynamics say that the total entropy of a system can never decline, so if it falls somewhere it must increase somewhere else. “The only possibility for the material to get rid of this extra mess is to pour it into the lattice” of its crystal structure, he says. That extra disorder means that the atoms themselves start vibrating faster, resulting in a rise in temperature.

Misplaced concern about existential risk is impeding the opportunity to expand human potential, writes venture capitalist Vinod Khosla. From his op-ed: I was the first venture investor in OpenAI. The weekend drama illustrated my contention that the wrong boards can damage companies. Fancy titles like “Director of Strategy at Georgetown’s Center for Security and Emerging Technology” can lead to a false sense of understanding of the complex process of entrepreneurial innovation. OpenAI’s board members’ religion of “effective altruism” and its misapplication could have set back the world’s path to the tremendous benefits of artificial intelligence. Imagine free doctors for everyone and near free tutors for every child on the planet. That’s what’s at stake with the promise of AI.

The best companies are those whose visions are led and executed by their founding entrepreneurs, the people who put everything on the line to challenge the status quo — founders like Sam Altman — who face risk head on, and who are focused — so totally — on making the world a better place. Things can go wrong, and abuse happens, but the benefits of good founders far outweigh the risks of bad ones. […] Large, world-changing vision is axiomatically risky. It can even be scary. But it is the sole lever by which the human condition has improved throughout history. And we could destroy that potential with academic talk of nonsensical existential risk in my view.

There is a lot of benefit on the upside, with a minuscule chance of existential risk. In that regard, it is more similar to what the steam engine and internal combustion engine did to human muscle power. Before the engines, we had passive devices — levers and pulleys. We ate food for energy and expended it for function. Now we could feed these engines oil, steam and coal, reducing human exertion and increasing output to improve the human condition. AI is the intellectual analog of these engines. Its multiplicative power on expertise and knowledge means we can supersede the current confines of human brain capacity, bringing great upside for the human race.

I understand that AI is not without its risks. But humanity faces many small risks. They range from vanishingly small like sentient AI destroying the world or an asteroid hitting the earth, to medium risks like global biowarfare from our adversaries, to large and looming risks like a technologically superior China, cyberwars and persuasive AI manipulating users in a democracy, likely starting with the U.S.’s 2024 elections.
