Cyberattack Knocks Mobile Guardian MDM Offline, Wipes Thousands of Student Devices

Slashdot - Wed, 2024-08-07 02:50
Zack Whittaker reports via TechCrunch: A cyberattack on Mobile Guardian, a U.K.-based provider of educational device management software, has sparked outages at schools across the world and has left thousands of students unable to access their files. Mobile Guardian acknowledged the cyberattack in a statement on its website, saying it identified "unauthorized access to the iOS and ChromeOS devices enrolled to the Mobile Guardian platform." The company said the cyberattack "affected users globally," including in North America, Europe and Singapore, and that the incident resulted in an unspecified portion of its userbase having their devices unenrolled from the platform and "wiped remotely." "Users are not currently able to log in to the Mobile Guardian Platform and students will experience restricted access on their devices," the company said. Mobile device management (MDM) software allows businesses and schools to remotely monitor and manage entire fleets of devices used by employees or students. Singapore's Ministry of Education, touted as a significant customer of Mobile Guardian on the company's website since 2020, said in a statement overnight that thousands of its students had devices remotely wiped during the cyberattack. "Based on preliminary checks, about 13,000 students in Singapore from 26 secondary schools had their devices wiped remotely by the perpetrator," the Singaporean education ministry said in a statement. The ministry said it was removing the Mobile Guardian software from its fleet of student devices, including affected iPads and Chromebooks.

WordStar 7, the Last Ever DOS Version, Is Re-Released For Free

Slashdot - Wed, 2024-08-07 02:10
An anonymous reader quotes a report from The Register: Before WordPerfect, the most popular work processor was WordStar. Now, the last ever DOS version has been bundled and set free by one of its biggest fans. WordStar 7.0d was the last-ever DOS release of the classic word processor, and it still has admirers today. A notable enthusiast is Canadian SF writer Robert J Sawyer, who wrote the book that became the TV series Flashforward. Thanks to his efforts you can now try out this pinnacle of pre-Windows PC programs for professional prose-smiths. Sawyer has taken the final release, packaged it up along with some useful tools -- including DOS emulators for modern Windows -- and shared the result. Now you, too, can revel in the sheer unbridled power of this powerful app. The download is 680MB, but as well as the app itself, full documentation, and some tools to help translate WordStar documents to more modern formats, it also includes copies of two FOSS tools that will let you run this MS-DOS application on modern Windows: DOSbox-X and vDosPlus. "The program has been a big part of my career -- not only did I write all 25 of my novels and almost all of my short stories with it (a few date back to the typewriter era), I also in my earlier freelance days wrote hundreds of newspaper and magazine articles with WordStar," says Sawyer.

Google and Cloudflare Summoned To Explain Their Plans To Defeat Pirate IPTV

Slashdot - Wed, 2024-08-07 01:30
Italy's telecoms regulator AGCOM has summoned Google and Cloudflare to a September meeting to discuss strategies for combating online piracy, six months after launching its Piracy Shield blocking system. The move comes as IPTV piracy remains resilient despite new anti-piracy legislation passed in the country last year. The law introduced harsher penalties for providers and consumers of pirated content, including fines for watching pirate streams. It also granted more aggressive site-blocking powers. Major stream suppliers appear minimally affected by overseas laws. however. AGCOM chief Massimiliano Capitanio seeks commitments from Google to limit pirate services in search results, according to TorrentFreak. The regulator also wants Cloudflare to address IPTV providers using its services to evade blocking.

Apple Discontinues USB SuperDrive After 16 Years

Slashdot - Wed, 2024-08-07 00:50
Apple is discontinuing its USB CD and DVD player accessory, the Apple USB SuperDrive. "As noted by one of our readers, it's no longer possible to buy an Apple USB SuperDrive online via the official Apple Store in the US," reports 9to5Mac. "The product's webpage says that it's 'Sold Out,' and given that it's a product introduced in 2008, it seems very unlikely that Apple will ever produce new units again." From the report: Customers can still use their location to see if there's still a unit available for pickup at one of the Apple Retail Stores. The product is still available in other countries such as the UK and Brazil. However, it's probably only a matter of time before Apple's USB SuperDrive disappears from all stores. The MacBook Air was the first MacBook without a built-in CD drive, which led the company to introduce an optical drive sold separately. Apple completely phased out optical drives from its computers in 2013, when all the Macs available in the lineup no longer had a CD reader.

Where Facebook's AI Slop Comes From

Slashdot - Wed, 2024-08-07 00:10
Facebook's AI-generated content problem is being fueled by its own creator bonus program, according to an investigation by 404 Media. The program incentivizes users, particularly from developing countries, to flood the platform with AI-generated images for financial gain. The outlet found that influencers in India and Southeast Asia are teaching followers how to exploit Facebook's algorithms and content moderation systems to go viral with AI-generated images. Many use Microsoft's Bing Image Creator to produce bizarre, often emotive content that garners high engagement. "The post you are seeing now is of a poor man that is being used to generate revenue," said Indian YouTuber Gyan Abhishek in a video, pointing to an AI image of an emaciated elderly man. He claimed users could earn "$100 for 1,000 likes" through Facebook's bonus program. While exact payment rates vary, 404 Media verified that consistent viral posting can lead to significant earnings for users in countries like India. Meta has defended the program to 404 Media, stating it works as intended if content meets community standards and engagement is authentic.

Slashdot - Tue, 2024-08-06 23:30
A Reddit user discovered the backend prompts for Apple Intelligence in the developer beta of macOS 15.1, offering a rare glimpse into the specific guidelines for Apple's AI functionalities. Some of the most notable instructions include: "Do not write a story that is religious, political, harmful, violent, sexual, filthy, or in any way negative, sad, or provocative"; "Do not hallucinate"; and "Do not make up factual information." MacRumors reports: For the Smart Reply feature, the AI is programmed to identify relevant questions from an email and generate concise answers. The prompt for this feature is as follows: "You are a helpful mail assistant which can help identify relevant questions from a given mail and a short reply snippet. Given a mail and the reply snippet, ask relevant questions which are explicitly asked in the mail. The answer to those questions will be selected by the recipient which will help reduce hallucination in drafting the response. Please output top questions along with set of possible answers/options for each of those questions. Do not ask questions which are answered by the reply snippet. The questions should be short, no more than 8 words. The answers should be short as well, around 2 words. Present your output in a json format with a list of dictionaries containing question and answers as the keys. If no question is asked in the mail, then output an empty list. Only output valid json and nothing else." The Memories feature in Apple Photos, which creates video stories from user photos, follows another set of detailed guidelines. The AI is instructed to generate stories that are positive and free of any controversial or harmful content. The prompt for this feature is: "A conversation between a user requesting a story from their photos and a creative writer assistant who responds with a story. Respond in JSON with these keys and values in order: traits: list of strings, visual themes selected from the photos; story: list of chapters as defined below; cover: string, photo caption describing the title card; title: string, title of story; subtitle: string, safer version of the title. Each chapter is a JSON with these keys and values in order: chapter: string, title of chapter; fallback: string, generic photo caption summarizing chapter theme; shots: list of strings, photo captions in chapter. Here are the story guidelines you must obey: The story should be about the intent of the user; The story should contain a clear arc; The story should be diverse, that is, do not overly focus the entire story on one very specific theme or trait; Do not write a story that is religious, political, harmful, violent, sexual, filthy or in any way negative, sad or provocative. Here are the photo caption list guidelines you must obey. Apple's AI tools also include a general directive to avoid hallucination. For instance, the Writing Tools feature has the following prompt: "You are an assistant which helps the user respond to their mails. Given a mail, a draft response is initially provided based on a short reply snippet. In order to make the draft response nicer and complete, a set of question and its answer are provided. Please write a concise and natural reply by modifying the draft response to incorporate the given questions and their answers. Please limit the reply within 50 words. Do not hallucinate. Do not make up factual information."

Figure AI's Humanoid Robot Helped Assemble BMWs At US Factory

Slashdot - Tue, 2024-08-06 22:52
An anonymous reader quotes a report from Ars Technica: Unlike Tesla, which hopes to develop its own bipedal 'bot to work on its production line sometime next year, BMW has brought in a robot from Figure AI. The Figure 02 robot has hands with sixteen degrees of freedom and human-equivalent strength. "We are excited to unveil Figure 02, our second-generation humanoid robot, which recently completed successful testing at the BMW Group Plant Spartanburg. Figure 02 has significant technical advancements, which enable the robot to perform a wide range of complex tasks fully autonomously," said Brett Adcock, founder and CEO of Figure AI. BMW wanted to test how to integrate a humanoid robot into its production process -- how to have the robot communicate with the production line software and human workers and determine what requirements would be necessary to add robots to the mix. The Figure robot was given the job of inserting sheet metal parts into fixtures as part of the process of making a chassis. BMW says this required particular dexterity and that it's an ergonomically awkward and tiring task for humans. Now that the trial is over, Figure's robot is no longer working at Spartanburg, and BMW says it has "no definite timetable established" to add humanoid robots to its production lines. "The developments in the field of robotics are very promising. With an early-test operation, we are now determining possible applications for humanoid robots in production. We want to accompany this technology from development to industrialization," said Milan Nedeljkovi, BMW's board member responsible for production. BMW Group published a video of the Figure 02 robot on YouTube.

Amazon, Microsoft, Google Remind Public of Their K-12 CS Education Philanthropy

Slashdot - Tue, 2024-08-06 21:25
theodp writes: After issuing mea culpas over diversity and compensation equity issues, tech companies began to promote their K-12 CS education philanthropy initiatives as corrective measures as they sought to deflect criticism and defeat shareholder calls for greater transparency into hiring and compensation practices. In 2016, for instance, Amazon argued it was already working with tech-backed nonprofits such as Code.org, the Anita Borg Institute, and Girls Who Code to increase women's and minorities' involvement in tech as it sought the SEC's permission to block a shareholder vote on a proposal on gender pay equality. As such, it wasn't terribly surprising to see the nation's tech giants again remind the public of their K-12 CS philanthropy efforts as they recently announced quarterly earnings. In the Addressing Racial Injustice and Inequity section of its most recent 10-K Annual Report SEC filing, Microsoft boasted, "We also expanded our Technology Education and Learning Support ("TEALS") program to reach nearly 550 high schools across 21 racial equity expansion regions with the support of nearly 1,500 volunteers, 12% of whom identify as Black or African American." An Amazon press release claimed the company is inspiring Girl Scouts to explore the future of STEM by awarding girls aged 7-and-up a co-branded Girl Scouts and Amazon patch for attending in-person or virtual Amazon warehouse tours. "As humanity looks to science, technology, engineering, and math (STEM) for new ideas and discoveries," Amazon explained, "it is more important than ever to harness the unique insights, skills, and potential of girls. [..] That's why Amazon partnered with Girl Scouts of the USA (GSUSA) to host exclusive tours [of Amazon fulfillment centers] for troops around the nation to showcase the importance and diversity of careers in STEM." Most recently, a press release celebrated the move of Google's Code Next high school program into a lab located in the newly-rehabbed Michigan Central Station, which has thus far enrolled approximately 100 students. "Google has called Michigan home for over 15 years with offices in Detroit and Ann Arbor. We're dedicated to investing in the city and providing its students with the resources and inspiration they need to excel," said Shanika Hope, Director, Google Education and Social Impact. "We're excited to bring our Code Next program to Michigan Central, empowering Detroit's youth with computer science education to help them reach their full potential in the classroom and beyond."

Apple Thinks Bing is Pretty Bad

Slashdot - Tue, 2024-08-06 20:42
U.S. Judge Amit Mehta released a 286-page ruling Monday in the Google search antitrust case, revealing key details of the tech giant's business practices. The document is packed with factual findings and legal conclusions and some amazing comments. Here's one, for instance: Google pays Apple billions of dollars a year to be the default search engine in Safari. But according to Eddy Cue, Apple's senior vice president of services, there's no other meaningful alternative. During the trial, he said that "there's no price that Microsoft could ever offer" to Apple to get the company to preload Bing in Safari. "I don't believe there's a price in the world that Microsoft could offer us," Cue said at another point. "They offered to give us Bing for free. They could give us the whole company." For Google, this is a sign that they've earned their default status (which, incidentally, they pay Apple gobs of money to maintain). Judge Mehta says that this is an indication that the "market reality is that Google is the only real choice as the default GSE [general search engine]." (Of course, Cue's opinion doesn't mean Bing is objectively bad. Elsewhere, the opinion notes that Bing's search quality is comparable to Google's on desktop, though it falls behind on mobile.)

Intel Foundry Achieves Major Milestones

Slashdot - Tue, 2024-08-06 20:02
Intel has announced significant progress on its 18A process technology, with lead products successfully powering on and booting operating systems. The company's Panther Lake client processor and Clearwater Forest server chip, both built on 18A, achieved these milestones less than two quarters after tape-out. The 18A node, featuring RibbonFET gate-all-around transistors and PowerVia backside power delivery, is on track for production in 2025. Intel released the 18A Process Design Kit 1.0 in July, enabling foundry customers to leverage these advanced technologies in their designs. "Intel is out ahead of everyone else in the industry with these innovations," Kevin O'Buckley, Intel's new head of Foundry Services stated, highlighting the node's potential to drive next-generation AI solutions. Clearwater Forest will be the industry's first mass-produced, high-performance chip combining RibbonFET, PowerVia, and Foveros Direct 3D packaging technology. It also utilizes Intel's 3-T base-die technology, showcasing the company's systems foundry approach. Intel expects its first external customer to tape out on 18A in the first half of 2025. EDA and IP partners are updating their tools to support customer designs on the new node. The success of 18A is crucial for Intel's ambitions to regain process leadership and grow its foundry business.

Need To Move 1.2 Exabytes Across the World Every Day? Just Effingo

Slashdot - Tue, 2024-08-06 18:50
An anonymous reader shares a report: Google has revealed technical details of its in-house data transfer tool, called Effingo, and bragged that it uses the project to move an average of 1.2 exabytes every day. As explained in a paper [PDF] and video to be presented on Thursday at the SIGCOMM 2024 conference in Sydney, bandwidth constraints and the stubbornly steady speed of light mean that not even Google is immune to the need to replicate data so it is located close to where it is processed or served. Indeed, the paper describes managed data transfer as "an unsung hero of large-scale, globally-distributed systems" because it "reduces the network latency from across-globe hundreds to in-continent dozens of milliseconds." The paper also points out that data transfer tools are not hard to find, and asks why a management layer like Effingo is needed. The answer is that the tools Google could find either optimized for transfer time or handled point-to-point data streams -- and weren't up to the job of handling the 1.2 exabytes Effingo moves on an average day, at 14 terabytes per second. To shift all those bits, Effingo "balances infrastructure efficiency and users' needs" and recognizes that "some users and some transfers are more important than the others: eg, disaster recovery for a serving database, compared to migrating data from a cluster with maintenance scheduled a week from now."

Microsoft Hits Back at Delta in Clash Over System Breakdown

Slashdot - Tue, 2024-08-06 18:15
Microsoft said Delta Air Lines turned down repeated offers for assistance following last month's catastrophic system outage, echoing claims by CrowdStrike in an increasingly contentious conflict between the carrier and its technology partners. From a report: Microsoft employees reached out to Delta to give technical support every day from July 19 through July 23, and "each time Delta turned down Microsoft's offers to help," according to a letter Tuesday from the technology giant's attorneys to Delta's representatives. Microsoft Chief Executive Officer Satya Nadella also personally emailed Delta CEO Ed Bastian and never heard back. "Even though Microsoft's software had not caused the CrowdStrike incident, Microsoft immediately jumped in and offered to assist Delta at no charge," according to the letter, which was signed by Mark Cheffo of Dechert LLP. The claims, in response to Delta's hiring of attorney David Boies, heighten the tension after Delta suggested it would try to seek compensation for a breakdown it expects to cost it $500 million this quarter. The airline was slower to recover than competitors after an errant software update from CrowdStrike affected Microsoft systems, creating a cascading effect that led Delta to cancel thousands of flights over several days.

Mainframes Find New Life in AI Era

Slashdot - Tue, 2024-08-06 16:40
Mainframe computers, stalwarts of high-speed data processing, are finding new relevance in the age of AI. Banks, insurers, and airlines continue to rely on these industrial-strength machines for mission-critical operations, with some now exploring AI applications directly on the hardware, WSJ reported in a feature story. IBM, commanding over 96% of the mainframe market, reported 6% growth in its mainframe business last quarter. The company's latest zSystem can process up to 30,000 transactions per second and hold 40 terabytes of data. WSJ adds: Globally, the mainframe market was valued at $3.05 billion in 2023, but new mainframe sales are expected to decline through 2028, IDC said. Of existing mainframes, however, 54% of enterprise leaders in a 2023 Forrester survey said they would increase their usage over the next two years. Mainframes do have limitations. They are constrained by the computing power within their boxes, unlike the cloud, which can scale up by drawing on computing power distributed across many locations and servers. They are also unwieldy -- with years of old code tacked on -- and don't integrate well with new applications. That makes them costly to manage and difficult to use as a platform for developing new applications.

The Biggest Loser in Google Search Ruling Could Be Mozilla and Firefox

Slashdot - Tue, 2024-08-06 16:00
Mozilla, the non-profit behind the Firefox browser, faces an uncertain future following Monday's landmark antitrust ruling against Google. The decision, which found Google illegally maintained its search monopoly, puts Mozilla's primary funding source at risk. In 2021-2022, Mozilla received $510 million from Google out of $593 million total revenue, according to its latest financial report. Fortune adds: You can be sure that critics of the judge's ruling will highlight the potentially devastating impact on Mozilla to make the case that the antitrust ruling will have unintended consequences on smaller tech industry players. Others might argue that Mozilla hasn't done enough with those spoils to differentiate its Firefox browser, or that it could cut a deal with another search engine like Bing if its Google deal goes away completely. Either way, Google will appeal the suit so a long battle may ensue. And there's another big domino to fall: the judge will rule on the remedy or remedies -- essentially, the business-model penalties -- that Google will face. Apple also stands to lose more than $20 billion a year that Google pays the iPhone-maker to be the default search engine on Safari. But as Fortune notes, "Apple is a large, diversified company with many sources of revenue."

Mac and Windows Users Infected By Software Updates Delivered Over Hacked ISP

Slashdot - Tue, 2024-08-06 15:00
An anonymous reader quotes a report from Ars Technica: Hackers delivered malware to Windows and Mac users by compromising their Internet service provider and then tampering with software updates delivered over unsecure connections, researchers said. The attack, researchers from security firm Volexity said, worked by hacking routers or similar types of device infrastructure of an unnamed ISP. The attackers then used their control of the devices to poison domain name system responses for legitimate hostnames providing updates for at least six different apps written for Windows or macOS. The apps affected were the 5KPlayer, Quick Heal, Rainmeter, Partition Wizard, and those from Corel and Sogou. Because the update mechanisms didn't use TLS or cryptographic signatures to authenticate the connections or downloaded software, the threat actors were able to use their control of the ISP infrastructure to successfully perform machine-in-the-middle (MitM) attacks that directed targeted users to hostile servers rather than the ones operated by the affected software makers. These redirections worked even when users employed non-encrypted public DNS services such as Google's 8.8.8.8 or Cloudflare's 1.1.1.1 rather than the authoritative DNS server provided by the ISP. "That is the fun/scary part -- this was not the hack of the ISPs DNS servers," Volexity CEO Steven Adair wrote in an online interview. "This was a compromise of network infrastructure for Internet traffic. The DNS queries, for example, would go to Google's DNS servers destined for 8.8.8.8. The traffic was being intercepted to respond to the DNS queries with the IP address of the attacker's servers." In other words, the DNS responses returned by any DNS server would be changed once it reached the infrastructure of the hacked ISP. The only way an end user could have thwarted the attack was to use DNS over HTTPS or DNS over TLS to ensure lookup results haven't been tampered with or to avoid all use of apps that deliver unsigned updates over unencrypted connections. As an example, the 5KPlayer app uses an unsecure HTTP connection rather than an encrypted HTTPS one to check if an update is available and, if so, to download a configuration file named Youtube.config. StormBamboo, the name used in the industry to track the hacking group responsible, used DNS poisoning to deliver a malicious version of the Youtube.config file from a malicious server. This file, in turn, downloaded a next-stage payload that was disguised as a PNG image. In fact, it was an executable file that installed malware tracked under the names MACMA for macOS devices or POCOSTICK for Windows devices. As for the hacked ISP, the security firm said "it's not a huge one or one you'd likely know." "In our case the incident is contained but we see other servers that are actively serving malicious updates but we do not know where they are being served from. We suspect there are other active attacks around the world we do not have purview into. This could be from an ISP compromise or a localized compromise to an organization such as on their firewall."

OpenAI Co-Founder John Schulman Is Joining Anthropic

Slashdot - Tue, 2024-08-06 12:00
OpenAI co-founder John Schulman announced Monday that he is leaving to join rival AI startup Anthropic. CNBC reports: The move comes less than three months after OpenAI disbanded a superalignment team that focused on trying to ensure that people can control AI systems that exceed human capability at many tasks. Schulman had been a co-leader of OpenAI's post-training team that refined AI models for the ChatGPT chatbot and a programming interface for third-party developers, according to a biography on his website. In June, OpenAI said Schulman, as head of alignment science, would join a safety and security committee that would provide advice to the board. Schulman has only worked at OpenAI since receiving a Ph.D. in computer science in 2016 from the University of California, Berkeley. "This choice stems from my desire to deepen my focus on AI alignment, and to start a new chapter of my career where I can return to hands-on technical work," Schulman wrote in the social media post. He said he wasn't leaving because of a lack of support for new work on the topic at OpenAI. "On the contrary, company leaders have been very committed to investing in this area," he said. The leaders of the superalignment team, Jan Leike and company co-founder Ilya Sutskever, both left this year. Leike joined Anthropic, while Sutskever said he was helping to start a new company, Safe Superintelligence Inc. "Very excited to be working together again!" Leike wrote in reply to Schulman's message.

Meteorite Impacts Produce Most of Moon's Thin Atmosphere, Study Reveals

Slashdot - Tue, 2024-08-06 09:00
Scientists studying lunar samples brought back by the Apollo missions have determined that the moon's thin atmosphere is produced largely by meteorite impacts. "Our findings provide a clearer picture of how the moon's surface and atmosphere interact over long timescales, [and] enhance our understanding of space weathering processes," said Dr Nicole Nie, the co-author of the new study based at MIT's department of Earth, atmospheric, and planetary sciences. The Guardian reports: Writing in the journal Science Advances, Nie and her colleagues describe how the lunar atmosphere must be constantly replenished because its atoms are continuously being lost to space, primarily because of the moon's weak gravity, or trapped on the lunar surface. Ultraviolet photons from the sun can rerelease the latter, but the researchers say replenishment of the atmosphere is thought to rely on atoms being released from within lunar minerals -- either via vaporisation by meteorite impacts, or by solar wind sputtering, a process in which charged particles from the sun hit the moon and eject atoms. But which of the two factors dominates had been unclear, with data from Nasa's lunar atmosphere and dust environment explorer, launched in 2013, suggesting both were at play. Nie and colleagues unpicked the conundrum by studying the different forms, or isotopes, of potassium and rubidium in 10 samples of lunar soil from the Apollo missions. The team say meteorite impacts and solar wind sputtering both favor the release of lighter forms of the elements, but that the actual proportion of heavy to light isotopes that end up in the lunar atmosphere and soil would differ depending on the process. "After measuring the isotopic compositions of lunar soils, we built a mathematical model taking into account various space weathering processes, and solve for the contribution of each of them by matching the measured isotopic compositions," said Nie. The results suggest about 70% of the moon's atmosphere is down to impact vaporization and 30% to solar wind sputtering.
