Cisco Donates the AGNTCY Project to the Linux Foundation 7

Cisco has donated its AGNTCY initiative to the Linux Foundation, aiming to create an open-standard "Internet of Agents" to allow AI agents from different vendors to collaborate seamlessly. The project is backed by tech giants like Google Cloud, Dell, Oracle and Red Hat. "Without such an interoperable standard, companies have been rushing to build specialized AI agents," writes ZDNet's Steven Vaughan-Nichols. "These work in isolated silos that cannot work and play well with each other. This, in turn, makes them less useful for customers than they could be." From the report: AGNTCY was first open-sourced by Cisco in March 2025 and has since attracted support from over 75 companies. By moving it under the Linux Foundation's neutral governance, the hope is that everyone else will jump on the AGNTCY bandwagon, thus making it an industry-wide standard. The Linux Foundation has a long history of providing common ground for what otherwise might be contentious technology battles. The project provides a complete framework to solve the core challenges of multi-agent collaboration:

- Agent Discovery: An Open Agent Schema Framework (OASF) acts like a "DNS for agents," allowing them to find and understand the capabilities of others.
- Agent Identity: A system for cryptographically verifiable identities ensures agents can prove who they are and perform authorized actions securely across different vendors and organizations.
- Agent Messaging: A protocol named Secure Low-latency Interactive Messaging (SLIM) is designed for the complex, multi-modal communication patterns of agents, with built-in support for human-in-the-loop interaction and quantum-safe security.
- Agent Observability: A specialized monitoring framework provides visibility into complex, multi-agent workflows, which is crucial for debugging probabilistic AI systems.

You may well ask, aren't there other emerging AI agency standards? You're right. There are. These include the Agent2Agent (A2A) protocol, which was also recently contributed to the Linux Foundation, and Anthropic's Model Context Protocol (MCP). AGNTCY will help agents using these protocols discover each other and communicate securely. In more detail, it looks like this: AGNTCY enables interoperability and collaboration in three primary ways:

- Discovery: Agents using the A2A protocol and servers using MCP can be listed and found through AGNTCY's directories. This enables different agents to discover each other and understand their functions.
- Messaging: A2A and MCP communications can be transported over SLIM, AGNTCY's messaging protocol designed for secure and efficient agent interaction.
- Observability: The interactions between these different agents and protocols can be monitored using AGNTCY's observability software development kits (SDKs), which increase transparency and help with debugging complex workflows

Cyberattack Cripples Russian Airline Aeroflot (politico.com) 36

New submitter Pravetz-82 shares a report from Politico: A cyberattack on Russian state-owned flagship carrier Aeroflot caused a mass outage to the company's computer systems on Monday, Russia's prosecutor's office said, forcing the airline to cancel more than 100 flights and delay others. Ukrainian hacker group Silent Crow and Belarusian hacker activist group the Belarus Cyber-Partisans, which opposes the rule of Belarusian President Alexander Lukashenko, claimed responsibility for the cyberattack. Images shared on social media showed hundreds of delayed passengers crowding Moscow's Sheremetyevo airport, where Aeroflot is based. The outage also disrupted flights operated by Aeroflot's subsidiaries, Rossiya and Pobeda. While most of the flights affected were domestic, the disruption also led to cancellations for some international flights to Belarus, Armenia and Uzbekistan.

Silent Crow claimed it had accessed Aeroflot's corporate network for a year, copying customer and internal data, including audio recordings of phone calls, data from the company's own surveillance on employees and other intercepted communications. "All of these resources are now inaccessible or destroyed and restoring them will possibly require tens of millions of dollars. The damage is strategic," the channel purporting to be the Silent Crow group wrote on Telegram. There was no way to independently verify its claims. The same channel also shared screenshots that appeared to show Aeroflot's internal IT systems, and insinuated that Silent Crow could begin sharing the data it had seized in the coming days. "The personal data of all Russians who have ever flown with Aeroflot have now also gone on a trip -- albeit without luggage and to the same destination," it said. The Belarus Cyber-Partisans told The Associated Press that they had hoped to "deliver a crushing blow."
Russia's Prosecutor's Office said it had opened a criminal investigation. Meanwhile, Kremlin spokesperson Dmitry Peskov called reports of the cyberattack "quite alarming," adding that "the hacker threat is a threat that remains for all large companies providing services to the general public."

'Serious Delays' Hit Satellite Mega-Constellations of China's Starlink Rivals (scmp.com) 29

"A Chinese mega-constellation of communications satellites is facing serious delays," reports the South China Morning Post, "that could jeopardise its ambitions to compete with SpaceX's Starlink for valuable orbital resources." Only 90 satellites have been launched into low Earth orbit for the Qianfan broadband network — also known as the Thousand Sails Constellation or G60 Starlink — well short of the project's goal of 648 by the end of this year... Shanghai Yuanxin Satellite Technology, the company leading the project, plans to deploy more than 15,000 satellites by 2030 to deliver direct-to-phone internet services worldwide. To stay on track, Yuanxin — which is backed by the Shanghai municipal government — would have to launch more than 30 satellites a month to achieve its milestones of 648 by the end of 2025 for regional coverage and 1,296 two years later for global connectivity.
The New York Times reports that "the other megaconstellation, Guowang, is even farther behind. Despite plans to launch about 13,000 satellites within the next decade, it has 34 in orbit." A constellation has to launch half of its satellites within five years of successfully applying for its frequencies, and complete the full deployment within seven years, according to rules set by the International Telecommunication Union, a United Nations agency that allocates frequencies. The Chinese megaconstellations are behind on these goals. Companies that fail to hit their targets could be required to reduce the size of their megaconstellations.
Meanwhile SpaceX "has about 8,000 Starlink satellites in orbit and is expanding its lead every month," the Times writes, citing data from the U.S. Space Force and the nonprofit space-data group CelesTrak. (The Times has even created an animation showing Starlink's 8,000 satellites in orbit.) Researchers for the People's Liberation Army predict that the network will become "deeply embedded in the U.S. military combat system." They envision a time when Starlink satellites connect U.S. military bases and serve as an early missile-warning and interception network....

One of the major reasons for China's delay is the lack of a reliable, reusable launcher. Chinese companies still launch satellites using single-use rockets. After the satellites are deployed, rocket parts tumble back to Earth or become space debris... Six years after [SpaceX's] Falcon 9 began launching Starlink satellites, Chinese firms still have no answer to it... The government has tested nearly 20 rocket launchers in the "Long March" series.

Starlink Suffers Worldwide Outage (mirror.co.uk) 43

Longtime Slashdot reader gbkersey shares a report from The Mirror: Elon Musk's satellite internet Starlink has been hit with a global outage preventing thousands of users from accessing the internet. According to DownDetector, reports of issues began to surge around 8pm GMT, with nearly 60,000 global users affected at the peak of the outage. "Starlink is currently in a network outage and we are actively implementing a solution," the company said in a post on X. "We appreciate your patience, we'll share an update once this issue is resolved."

Outages are being reported across the U.S., as well as along the Ukrainian frontline. Meanwhile, more than 10,000 people in the UK have logged issues with Starlink since 8pm this evening. "The majority of the reports (64%) are concerning a total blackout, while the rest point to internet problems," the report says.

UPDATE: Michael Nicolls, VP of Starlink Engineering, wrote in a post: "Starlink has now mostly recovered from the network outage, which lasted approximately 2.5 hours. The outage was due to failure of key internal software services that operate the core network. We apologize for the temporary disruption in our service; we are deeply committed to providing a highly reliable network, and will fully root cause this issue and ensure it does not occur again."

UPDATE #2: Starlink said in an update at 5:18 PM PT: "The network issue has been resolved, and Starlink service has been restored. We understand how important connectivity is and apologize for the disruption."

Starlink-Powered 'T-Satellite' Service Is Now Live On T-Mobile (theverge.com) 10

T-Mobile has officially launched its Starlink-powered "T-Satellite" service nationwide, offering off-grid text messaging and location-sharing to both customers and non-customers. The service is currently $10/month (soon to be $15), supports over 60 devices, and will expand to include voice and "satellite-optimized" apps. The Verge reports: Your device will automatically connect to T-Satellite if you're in an area with no cellular coverage. As long as there isn't a heavy amount of cloud coverage or trees blocking your view of the sky, you should be able to send and receive text messages, including to 911, as well as share a link that temporarily tracks your location. T-Mobile's support page says the ability to send pictures is available on "most" Android phones, and the company plans on adding support for more devices soon.

T-Mobile is also aiming to enable voice messages and will eventually allow devices to connect to "satellite-optimized" apps, which it previously said could include AllTrails, Accuweather, and WhatsApp. The more than 650 Starlink satellites used by T-Mobile cover the continental US, Hawaii, parts of southern Alaska, and Puerto Rico. The carrier says it's working on offering satellite connectivity while abroad and in international waters as well. [...] In order to use T-Satellite, you'll need to have an unlocked device with support for eSIMs and satellite connectivity.

COVID Pandemic Aged Brains By an Average of 5.5 Months, Study Finds 34

An anonymous reader quotes a report from NBC News: Using brain scans from a very large database, British researchers determined that during the pandemic years of 2021 and 2022, people's brains showed signs of aging, including shrinkage, according to the report published in Nature Communications. People who got infected with the virus also showed deficits in certain cognitive abilities, such as processing speed and mental flexibility. The aging effect "was most pronounced in males and those from more socioeconomically deprived backgrounds," said the study's first author, Ali-Reza Mohammadi-Nejad, a neuroimaging researcher at the University of Nottingham, via email. "It highlights that brain health is not shaped solely by illness, but also by broader life experiences."

Overall, the researchers found a 5.5-month acceleration in aging associated with the pandemic. On average, the difference in brain aging between men and women was small, about 2.5 months. "We don't yet know exactly why, but this fits with other research suggesting that men may be more affected by certain types of stress or health challenges," Mohammadi-Nejad said. [...] The study wasn't designed to pinpoint specific causes. "But it is likely that the cumulative experience of the pandemic -- including psychological stress, social isolation, disruptions in daily life, reduced activity and wellness -- contributed to the observed changes," Mohammadi-Nejad said. "In this sense, the pandemic period itself appears to have left a mark on our brains, even in the absence of infection."
"The most intriguing finding in this study is that only those who were infected with SARS-CoV-2 showed any cognitive deficits, despite structural aging," said Jacqueline Becker, a clinical neuropsychologist and assistant professor of medicine at the Icahn School of Medicine at Mount Sinai. "This speaks a little to the effects of the virus itself."

The study may shed light on conditions like long Covid and chronic fatigue, though it's still unclear whether the observed brain changes in uninfected individuals will lead to noticeable effects on brain function.

California Won't Force ISPs To Offer $15 Broadband (arstechnica.com) 74

An anonymous reader quotes a report from Ars Technica: A California lawmaker halted an effort to pass a law that would force Internet service providers to offer $15 monthly plans to people with low incomes. Assemblymember Tasha Boerner proposed the state law a few months ago, modeling the bill on a law enforced by New York. It seemed that other states were free to impose cheap-broadband mandates because the Supreme Court rejected broadband industry challenges to the New York law twice.

Boerner, a Democrat who is chair of the Communications and Conveyance Committee, faced pressure from Internet service providers to change or drop the bill. She made some changes, for example lowering the $15 plan's required download speeds from 100Mbps to 50Mbps and the required upload speeds from 20Mbps to 10Mbps. But the bill was still working its way through the legislature when, according to Boerner, Trump administration officials told her office that California could lose access to $1.86 billion in Broadband Equity, Access, and Deployment (BEAD) funds if it forces ISPs to offer low-cost service to people with low incomes.

That amount is California's share of a $42.45 billion fund created by Congress to expand access to broadband service. The Trump administration has overhauled program rules, delaying the grants. One change is that states can't tell ISPs what to charge for a low-cost plan. The US law that created BEAD requires Internet providers receiving federal funds to offer at least one "low-cost broadband service option for eligible subscribers." But in new guidance from the National Telecommunications and Information Administration (NTIA), the agency said it prohibits states "from explicitly or implicitly setting the LCSO [low-cost service option] rate a subgrantee must offer."
"All they would have to do to get exempted from AB 353 [the $15 broadband bill] would be to apply to the BEAD program," said Boerner. "Doesn't matter if their application was valid, appropriate, granted, or they got public money at the end of the day and built the projects -- the mere application for the BEAD program would exempt them from 353, if it didn't jeopardize from $1.86 billion to begin with. And that was a tradeoff I was unwilling to make."

Another California bill in the Senate would encourage, not require, ISPs to offer cheap broadband by making them eligible for Lifeline subsidies if they sell 100/20Mbps service for $30 or less.

In Shallow Water Ships Trigger Seafloor Methane Emissions, Study Finds (msn.com) 52

An anonymous reader shared this report from the Washington Post: Ships trigger seafloor methane emissions while moving through shallow water, researchers report in Communications Earth & Environment. The scientists say the unexpected discovery has nothing to do with the type of fuel used by the ship. Instead, "ship-induced pressure changes and turbulent mixing" trigger the release of the gas from the seafloor. Bubbles and gas diffusion push the methane into the atmosphere, where it acts as a greenhouse gas...

Container and cruise ships triggered the largest and most frequent methane emissions, but the study suggests that ships of all kinds, regardless of their type of engine or size, trigger methane emissions. Researchers said they observed emissions that were 20 times higher in the shipping lane than in undisturbed nearby areas. Given the number of ports in similarly shallow areas worldwide, it's important to learn more about emissions in shipping lanes and to better estimate their "hitherto unknown impact," study co-author Johan Mellqvist, a professor of optical remote sensing at Chalmers University of Technology in Sweden, said in a news release.

Chinese Companies Now Authorized to Conduct Foreign Cyberattacks, Sell Access to Government (msn.com) 57

"The U.S. is absolutely facing the most serious Chinese hacking ever." That's what the Washington Post was told by a China-focused consultant at security company SentinelOne: Undeterred by recent indictments alleging widespread cyberespionage against American agencies, journalists and infrastructure targets, Chinese hackers are hitting a wider range of targets and battling harder to stay inside once detected, seven current and former U.S. officials said in interviews. Hacks from suspected Chinese government actors detected by the security firm CrowdStrike more than doubled from 2023 to more than 330 last year and continued to climb as the new administration took over, the company said... Although the various Chinese hacking campaigns seem to be led by different government agencies and have different goals, all benefit from new techniques and from Beijing's introduction of a less constrained system for cyber offense, the officials and outside researchers told The Washington Post... Chinese intelligence, military and security agencies previously selected targets and tasked their own employees with breaking in, they said. But the Chinese government decided to take a more aggressive approach by allowing private industry to conduct cyberattacks and hacking campaigns on their own, U.S. officials said.

The companies are recruiting top hackers who discover previously unknown, or "zero-day," flaws in software widely used in the United States. Then the companies search for where the vulnerable programs are installed, hack a great many of them at once, and then sell access to multiple Chinese government customers and other security companies. That hacking-for-hire approach creates hundreds of U.S. victims instead of a few, making it hard to block attacks and to decide which were China's key targets and which were unintentionally caught in the hacks, an FBI official said, speaking on the condition of anonymity to follow agency practices... "The result of that incentive structure is that there is significantly more hacking...."

China has mastered the ability to move undetected through networks of compromised U.S. devices, so that the final connection to a target appears to be an ordinary domestic connection. That makes it easy to get around technology that blocks overseas links and puts it outside the purview of the National Security Agency, which by law must avoid scrutinizing most domestic transmissions. Beijing is increasingly focused on hacking software and security vendors that provide access to many customers at once, the FBI official said. Once access is obtained, the hackers typically add new email and collaboration accounts that look legitimate... Beyond the increased government collaboration with China's private security sector is occasional collaborating with criminal groups, said Ken Dunham, an analyst at the security firm Qualys.

The article notes that China's penetration of U.S. telecom carriers "is still not fully contained, according to the current and former officials." But in addition, the group behind that attack "has more recently shown up inside core communications infrastructure in Europe, according to John Carlin, a former top national security official in the Justice Department who represents some U.S. victims of the group." And documents leaked last year from a security contractor that works with the Chinese military and other government groups "described contracts and targets in 20 countries, with booty including Indian immigration data, logs of calls in South Korea, and detailed information on roads in Taiwan.

"It also detailed prices for some services, such as $25,000 for promised remote access to an iPhone, payment disputes with government customers and employee gripes about long hours..."

SES Completes $3 Billion Acquisition of Intelsat, Expanding Global Satellite Fleet (ses.com) 4

"The Luxembourg-based satellite company SES has now completed its acquisition of the European-based satellite company Intelsat, giving the combined company 120 active satellites in a variety of low and high Earth orbits," writes longtime Slashdot reader schwit1. "Both companies are long established, with Intelsat initially founded in the mid-1960s as a consortium of 23 nations aimed at launching the first geosynchronous communications satellites over the Atlantic and Pacific serving most of the Old World and linked to the New. The merger is an attempt by both companies to compete with the new low-orbit constellations of SpaceX, Amazon, and from China." From a press release: With a world-class network including approximately 90 geostationary (GEO), nearly 30 medium earth orbit (MEO) satellites, strategic access to low earth orbit (LEO) satellites, and an extensive ground network, SES can now deliver connectivity solutions utilizing complementary spectrum bands including C-, Ku-, Ka-, Military Ka-, X-band, and Ultra High Frequency. The expanded capabilities of the combined company will enable it to deliver premium-quality services and tailored solutions to its customers. The company's assets and networks, once fully integrated, will put SES in a strong competitive position to better serve the evolving needs of its customers including governments, aviation, maritime, and media across the globe. "Our focus is clear: to grow, to lead in high-potential markets, and to shape the future of our industry," said SES CEO Adel Al-Saleh in a statement. "This is a long-term play, and we are building with the future in mind -- growing year after year, expanding our capabilities, and creating lasting value for our customers and shareholders alike."

Fierce Network notes that the FCC is preparing to auction upper C-band spectrum (3.98-4.2 GHz), previously cleared in part by SES and Intelsat and now eyed for 5G expansion by Verizon and AT&T. With new legislative backing and industry pressure, including from CTIA and FCC Chairman Brendan Carr, the agency is being urged to act quickly to auction and open this spectrum for full-power wireless use.

Transatlantic Communications Cable Doubles As Ocean Sensor (phys.org) 6

alternative_right shares a report from Phys.org: Monitoring changes in water temperature and pressure at the seafloor can improve understanding of ocean circulation, climate, and natural hazards such as tsunamis. In recent years, scientists have begun gathering submarine measurements via an existing infrastructure network that spans millions of kilometers around the planet: the undersea fiber-optic telecommunications cables that provide us with amenities like Internet and phone service. Without interfering with their original purpose, the cables can be used as sensors to measure small variations in the light signals that run through them so that scientists can learn more about the sea. Meichen Liu and colleagues recently developed a new instrument, consisting of a receiver and a microwave intensity modulator placed at a shore station, that facilitates the approach. Their work is published in Geophysical Research Letters.

Transcontinental fiber-optic cables are divided into subsections by repeaters, instruments positioned every 50 to 100 kilometers that boost information-carrying light signals so that they remain strong on the journey to their destination. At each repeater, an instrument called a fiber Bragg grating reflects a small amount of light back to the previous repeater to monitor the integrity of the cable. By observing and timing these reflections, the new instrument measures the changes in the time it takes for the light to travel between repeaters. These changes convey information about how the surrounding water changes the shape of the cable, and the researchers used that information to infer properties such as daily and weekly water temperature and tide patterns.

Japan Sets New Internet Speed Record, Surpassing Average US Broadband Speeds By 4 Million Times 37

A team of Japanese researchers has set a new world record for internet speed, transmitting data at 125,000 gigabytes per second over 1,120 miles using a new type of 19-core optical fiber. "That's about 4 million times the average internet speed in the U.S. and would allow you to download the entire Internet Archive in less than four minutes," notes Live Science. It's also "more than twice the previous world record of 50,250 Gbps, previously set by a different team of scientists in 2024." From the report: To achieve this new speed -- which has not been independently verified -- the team developed a new form of optical fiber to send information at groundbreaking speeds over roughly the distance between New York and Florida. Details about this achievement were presented April 3 at the 48th Optical Fiber Communication Conference in San Francisco, according to a statement from Japan's National Institute of Information and Communications Technology.

The new type of optical fiber is equivalent to 19 standard optical fibers in its data transmission capacity. The new optical fiber is better suited to long-haul transmission than existing cables because the centers of all 19 fibers interact with light in the same way, so they encounter less light fluctuation, which results in less data loss. The new cable squeezes 19 separate fibers into a diameter of five-thousandths of an inch (0.127 millimeters), which is the same thickness as most existing single-fiber cables already in use. This effort means the new cable can transmit more data using existing infrastructure. [...] For this demonstration, the data ran through a transmission system 21 times, finally reaching a data receiver after traveling the equivalent of 1,120 miles.

FCC Chair Accused of 'Political Theater' to Please Net Neutrality's Foes (freepress.net) 35

The advocacy group Free Press on Friday blasted America's Federal Communications Commission chief "for an order that rips net neutrality rules off the books, without any time for public comment, following an unfavorable court ruling," reports the nonprofit progressive news site Common Dreams: A panel from the U.S. Court of Appeals for the 6th Circuit ruled in January that broadband is an "information service" instead of a "telecommunications service" under federal law, and the FCC did not have the authority to prohibit internet service providers (ISPs) from creating online "fast lanes" and blocking or throttling web content... FCC Chair Brendan Carr said in a Friday statement that as part of his "Delete, Delete, Delete" initiative, "we're continuing to clean house at the FCC, working to identify and eliminate rules that no longer serve a purpose, have been on our books for decades, and have no place in the current Code of Federal Regulations...."

Responding in a lengthy statement, Free Press vice president of policy and general counsel Matt Wood said that "the FCC's so-called deletion today is little more than political grandstanding. It's true that the rules in question were first stayed by the 6th Circuit and then struck down by that appellate court — in a poorly reasoned opinion. So today's bookkeeping maneuver changes very little in reality... There's no need to delete currently inoperative rules, much less to announce it in a summer Friday order. The only reason to do that is to score points with broadband monopolies and their lobbyists, who've fought against essential and popular safeguards for the past two decades straight...."

Wood noted that "the appeals process for this case has not even concluded yet, as Free Press and allies sought and got more time to consider our options at the Supreme Court. Today's FCC order doesn't impact either our ability to press the case there or our strategic considerations about whether to do so," he added. "It's little more than a premature housekeeping step..."

Chinese Satellites Complete First High-Altitude Rendezvous For Possible Groundbreaking Refueling (extremetech.com) 14

Two Chinese satellites, SJ-25 and SJ-21, have reportedly completed the first autonomous high-altitude orbital docking. "Although unconfirmed, this is thought to be the first orbital refueling at such a height -- the two satellites are currently over 20,000 miles from Earth," reports ExtremeTech. From the report: Orbital refueling is an important component in keeping satellites and space stations in low Earth orbit flying, but any efforts beyond that have been merely speculative until the past few years, when serious efforts from a range of private and national entities have explored its possibilities. China may have gotten ahead of the curve with this latest docking, though, in an impressive world first that raises serious concerns for satellites from nations and entities that align themselves differently from China's goals and ambitions.

In January, a satellite designated SJ-25 was launched "for the verification of satellite fuel replenishment and life extension service technologies," according to the Chinese state-owned designer, Shanghai Academy of Spaceflight Technology (via Ars Technica). Sometime last week, it matched orbits with the SJ-21 satellite, which previously conducted space debris maneuvering tests in 2021 and has remained in a geosynchronous orbit ever since.

Last week, the two satellites matched orbits and seemingly docked together. Analysts believe the newer SJ-25 has likely proven refueling is possible even for geosynchronous satellites without the need for a manned crew to facilitate it. In an effort to prove this, two US Space Force's inspector satellites have positioned themselves in closer orbits to SJ-25 and SJ-21 for improved optics. [...] China continues to suggest these missions are part of a debris clean-up program, though it hasn't publicly made any statements about the recent alleged docking and refueling to celebrate its successes. If it doesn't, the only way we'll know if a refueling maneuver was successful is if the SJ-21 satellite unshackles from its younger sibling and performs fuel-demanding maneuvers that its previously estimated fuel levels shouldn't allow for.

Hacker With 'Political Agenda' Stole Data From Columbia, University Says (therecord.media) 28

A politically motivated hacker breached Columbia University's IT systems, stealing vast amounts of sensitive student and employee data -- including admissions decisions and Social Security numbers. The Record reports: The hacker reportedly provided Bloomberg News with 1.6 gigabytes of data they claimed to have stolen from the university, including information from 2.5 million applications going back decades. The stolen data the outlet reviewed reportedly contains details on whether applicants were rejected or accepted, their citizenship status, their university ID numbers and which academic programs they sought admission to. While the hacker's claims have not been independently verified, Bloomberg said it compared data provided by the hacker to that belonging to eight Columbia applicants seeking admission between 2019 and 2024 and found it matched.

The threat actor reportedly told Bloomberg he was seeking information that would indicate whether the university continues to use affirmative action in admissions despite a 2023 Supreme Court decision prohibiting the practice. The hacker told Bloomberg he obtained 460 gigabytes of data in total -- after spending two months targeting and penetrating increasingly privileged layers of the university's servers -- and said he harvested information about financial aid packages, employee pay and at least 1.8 million Social Security numbers belonging to employees, applicants, students and their family members.

Bezos-Backed Methane Tracking Satellite Is Lost In Space (reuters.com) 60

MethaneSAT, an $88 million satellite backed by Jeff Bezos and led by the Environmental Defense Fund to track global methane emissions, has been lost in space after going off course and losing power over Norway. "We're seeing this as a setback, not a failure," Amy Middleton, senior vice president at EDF, told Reuters. "We've made so much progress and so much has been learned that if we hadn't taken this risk, we wouldn't have any of these learnings." Reuters reports: The launch of MethaneSAT in March 2024 was a milestone in a years-long campaign by EDF to hold accountable the more than 120 countries that in 2021 pledged to curb their methane emissions. It also sought to help enforce a further promise from 50 oil and gas companies made at the Dubai COP28 climate summit in December 2023 to eliminate methane and routine gas flaring. [...] While MethaneSAT was not the only project to publish satellite data on methane emissions, its backers said it provided more detail on emissions sources and it partnered with Google to create a publicly-available global map of emissions.

EDF reported the lost satellite to federal agencies including the National Oceanic and Atmospheric Administration, Federal Communications Commission and the U.S. Space Force on Tuesday, it said. Building and launching the satellite cost $88 million, according to the EDF. The organization had received a $100 million grant from the Bezos Earth Fund in 2020 and got other major financial support from Arnold Ventures, the Robertson Foundation and the TED Audacious Project and EDF donors.
