Recently, I had a learning experience with cron jobs and acme.sh. acme.sh is an excellent tool that simplifies the management of Let's Encrypt TLS (SSL) certificates. It makes obtaining and renewing these essential security certificates for your web server easier. Recently, I moved my server from Linode to AWS, which was a new environment for me. Initially, everything appeared to be working correctly, and I assumed everything was running smoothly. However, I forgot to migrate the cron job that acme.sh uses to renew the certificate automatically. This oversight caused my Let's Encrypt certificates to expire, resulting in security warnings and potential disruptions for visitors to my website. Opps!

A new study shows that earthquake monitoring networks can track falling space debris by detecting the sonic booms produced during atmospheric reentry, sometimes more accurately than radar. The Associated Press reports: Scientists reported Thursday that seismic readings from sonic booms that were generated when a discarded module from a Chinese crew capsule reentered over Southern California in 2024 allowed them to place the object's path nearly 20 miles (30 kilometers) farther south than radar had predicted from orbit. Using this method to track uncontrolled objects plummeting at supersonic speeds, they said, could help recovery teams reach any surviving pieces more quickly -- crucial if the debris is dangerous. "The problem at the moment is we can track stuff very well in space," said Johns Hopkins University's Benjamin Fernando, the lead researcher. "But once it gets to the point that it's actually breaking up in the atmosphere, it becomes very difficult to track." His team's findings, published in the journal Science, focus on just one debris event. But the researchers already have used publicly available data from seismic networks to track a few dozen other reentries, including debris from three failed SpaceX Starship test flights in Texas. [...] Fernando is looking to eventually publish a catalog of seismically tracked, entering space objects, while improving future calculations by factoring in the wind's effect on falling debris. In a companion article in Science, Los Alamos National Laboratory's Chris Carr, who was not involved in the study, said further research is needed to reduce the time between an object's final plunge and the determination of its course. For now, Carr said this new method "unlocks the rapid identification of debris fall-out zones, which is key information as Earth's orbit is anticipated to become increasingly crowded with satellites, leading to a greater influx of space debris."

Bruce66423 shares a report from the Guardian: New filtration technology developed by Rice University may absorb some Pfas "forever chemicals" at 100 times the rate than previously possible, which could dramatically improve pollution control and speed remediations. Researchers also say they have also found a way to destroy Pfas, though both technologies face a steep challenge in being deployed on an industrial scale. A new peer-reviewed paper details a layered double hydroxide (LDH) material made from copper and aluminum that absorbs long-chain Pfas up to 100 times faster than commonly used filtration systems. [...] [Michael Wong, director of Rice's Water Institute, a Pfas research center] said Rice's non-thermal process works by soaking up and concentrating Pfas at high levels, which makes it possible to destroy them without high temperatures. The LDH material Rice developed is a variation of similar materials previously used, but researchers replaced some aluminum atoms with copper atoms. The LDH material is positively charged and the long-chain Pfas are negatively charged, which causes the material to attract and absorb the chemicals, Wong said. [...] Pfas are virtually indestructible because their carbon atoms are bonded with fluoride, but Rice found that the bonds could be broken if the chemicals in the material were heated to 400-500C -- a relatively low temperature. The fluoride gets trapped in the LDH material and is bonded to calcium. The leftover calcium-fluoride material is safe and can be disposed of in a landfill, Wong said. The process works with some long-chain Pfas that are among the most common water pollutants, and it also absorbed some smaller Pfas that are commonplace. Wong said he is confident the material can be used to absorb a broad array of Pfas, especially if they are negatively charged. Most new Pfas elimination systems fail to work at an industrial scale. Wong said the new material has an advantage because its absorption rate is so strong, it can be used repeatedly and it is in a "drop in material," meaning it can be used with existing filtration infrastructure. That eliminates one of the major cost barriers.

California became the first U.S. state to join the World Health Organization's Global Outbreak Alert and Response Network (GOARN), one day after the U.S. formally exited the WHO. The Hill reports: This announcement comes just one day after the U.S.'s withdrawal from the WHO became official after nearly 80 years of membership, having been a founding member of the organization. "The Trump administration's withdrawal from WHO is a reckless decision that will hurt all Californians and Americans," [California Governor Gavin Newsom] said in a statement. "California will not bear witness to the chaos this decision will bring. We will continue to foster partnerships across the globe and remain at the forefront of public health preparedness, including through our membership as the only state in WHO's Global Outbreak Alert & Response Network."

Longtime Slashdot reader AmiMoJo shares a report from the Guardian: The financial campaigner James Daley has launched a 1.5 billion pound (approximately $1.5 billion) class action lawsuit against Apple over its mobile phone wallet, claiming the U.S. tech company blocked competition and charged hidden fees that ultimately harmed 50 million UK consumers. The lawsuit takes aim at Apple Pay, which they say has been the only contactless payment service available for iPhone users in Britain over the past decade. Daley, who is the founder of the advocacy group Fairer Finance, claims this situation amounted to anti-competitive behavior and allowed Apple to charge hidden fees, ultimately pushing up costs for banks that passed charges on to consumers, regardless of whether they owned an iPhone. It is the first UK legal challenge to the company's conduct in relation to Apple Pay, and takes place months after regulators like the Competition and Markets Authority and the Payments Systems Regulator began scrutinising the tech industry's digital wallet services. The case has been filed with the Competition Appeal Tribunal, which will now decide whether the class action case can move forward. [...] Daley's lawsuit alleges that Apple refused to give other app developers and outside businesses access to the contactless payment technology on its iPhones, which meant it could charge banks and card issuers fees on Apple Pay transactions that his lawyers say "are not in line with industry practice." The lawsuit notes that similar fees are not charged on equivalent payments on Android devices, which are built by Google. It says that the additional costs were borne by UK consumers, having been passed on through charges on a range of personal banking products ranging from current accounts, credit cards, to savings and mortgages. The lawsuit says that about 98% of consumers are exposed to banks that listed cards on Apple Pay, meaning the vast majority of the UK population may have been affected.

The U.S. Department of Justice has opened a criminal investigation into Deel over allegations that it recruited a spy inside rival Rippling, according to documents seen by The Wall Street Journal. From the report: An Ireland-based Rippling employee, Keith O'Brien, alleged in an affidavit filed in April that Deel Chief Executive Alex Bouaziz recruited him and gave him instructions for what information to take from Rippling. O'Brien alleged that other executives were involved in the spying plot, including Bouaziz's father, who is Deel's executive chairman and chief strategy officer. A spokeswoman for Deel said the company isn't aware of a criminal investigation but is willing to cooperate with authorities. The company has previously said: "We deny all legal wrongdoing and look forward to asserting our counterclaims." Unsealed court documents allege that an entity tied to Deel transferred $6,000 to an account owned by the wife of Chief Operating Officer Dan Westgarth, and that the same amount was forwarded from the account to O'Brien seconds later.

An anonymous reader quotes a report from Wired: When TikTok users in the U.S. opened the app today, they were greeted with a pop-up asking them to agree to the social media platform's new terms of service and privacy policy before they could resume scrolling. These changes are part of TikTok's transition to new ownership. In order to continue operating in the U.S., TikTok was compelled by the U.S. government to transition from Chinese control to a new, American-majority corporate entity. Called TikTok USDS Joint Venture LLC, the new entity is made up of a group of investors that includes the software company Oracle. It's easy to tap "agree" and keep on scrolling through videos on TikTok, so users might not fully understand the extent of changes they are agreeing to with this pop-up. Now that it's under U.S.-based ownership, TikTok potentially collects more detailed information about its users, including precise location data. Here are the three biggest changes to TikTok's privacy policy that users should know about. TikTok's change in location tracking is one of the most notable updates in this new privacy policy. Before this update, the app did not collect the precise, GPS-derived location data of U.S. users. Now, if you give TikTok permission to use your phone's location services, then the app may collect granular information about your exact whereabouts. Similar kinds of precise location data is also tracked by other social media apps, like Instagram and X. [...] Rather than an adjustment, TikTok's policy on AI interactions adds a new topic to the privacy policy document. Now, users' interactions with any of TikTok's AI tools explicitly fall under data that the service may collect and store. This includes any prompts as well as the AI-generated outputs. The metadata attached to your interactions with AI tools may also be automatically logged. [...] This change to TikTok's privacy policy may not be as immediately noticeable to users, but it will likely have an impact on the types of ads you see outside of TikTok. So, rather than just using your collected data to target you while using the app, TikTok may now further leverage that info to serve you more relevant ads wherever you go online. As part of this advertising change, TikTok also now explicitly mentions publishers as one kind of partner the platform works with to get new data.

The White House doubled down after posting a digitally altered photo of Minnesota protester Nekima Levy Armstrong, dismissing it as a "meme" despite objections from her attorney and comparisons to reality-distorting propaganda. "YET AGAIN to the people who feel the need to reflexively defend perpetrators of heinous crimes in our country I share with you this message: Enforcement of the law will continue. The memes will continue. Thank you for your attention to this matter," White House spokesperson Kaelan Dorr wrote in a post on X. The Hill reports: The statement came after Homeland Security Secretary Kristi Noem posted a photo of Armstrong's arrest Thursday showing Armstrong with what appears to be a blank facial expression. However, the White House later posted an altered version of the same photo that shows Armstrong crying. Armstrong's attorney Jordan Kushner said in an interview with CNN that an agent was recording Armstrong's arrest on their cellphone. "I've never seen anything like it. It's so unprofessional," Kushner said. "He was ordered to do it because the government was looking to make a spectacle of this case. I observed the whole thing. She was dignified, calm, rational the whole time." Kushner went on to call the move to alter the photo "a hallmark of a fascist regime where they actually alter reality."

Accelerated Linux page cache attacks detailed  SC Media

Jeffrey Snover, the driving force behind PowerShell, has retired after a career that reshaped Windows administration. The Register reports: Snover's retirement comes after a brief sojourn at Google as a Distinguished Engineer, following a lengthy stint at Microsoft, during which he pulled the company back from imposing a graphical user interface (GUI) on administrators who really just wanted a command line from which to run their scripts. Snover joined Microsoft as the 20th century drew to a close. The company was all about its Windows operating system and user interface in those days -- great for end users, but not so good for administrators managing fleets of servers. Snover correctly predicted a shift to server datacenters, which would require automated management. A powerful shell... a PowerShell, if you will. [...] Over the years, Snover has dropped the occasional pearl of wisdom or shared memories from his time getting PowerShell off the ground. A recent favorite concerns the naming of Cmdlets and their original name in Monad: Function Units, or FUs. Snover wrote: "This abbreviation reflected the Unix smart-ass culture I was embracing at the time. Plus I was developing this in a hostile environment, and my sense of diplomacy was not yet fully operational." Snover doubtless has many more war stories to share. In the meantime, however, we wish him well. Many admins owe Snover thanks for persuading Microsoft that its GUI obsession did not translate to the datacenter, and for lengthy careers in gluing enterprise systems together with some scripted automation.

Fake cryptocurrency wallet apps target Linux users with cryptostealers  SC Media

An anonymous reader quotes a report from TechCrunch: Microsoft provided the FBI with the recovery keys to unlock encrypted data on the hard drives of three laptops as part of a federal investigation, Forbes reported on Friday. Many modern Windows computers rely on full-disk encryption, called BitLocker, which is enabled by default. This type of technology should prevent anyone except the device owner from accessing the data if the computer is locked and powered off. But, by default, BitLocker recovery keys are uploaded to Microsoft's cloud, allowing the tech giant -- and by extension law enforcement -- to access them and use them to decrypt drives encrypted with BitLocker, as with the case reported by Forbes. The case involved several people suspected of fraud related to the Pandemic Unemployment Assistance program in Guam, a U.S. island in the Pacific. Local news outlet Pacific Daily News covered the case last year, reporting that a warrant had been served to Microsoft in relation to the suspects' hard drives. Kandit News, another local Guam news outlet, also reported in October that the FBI requested the warrant six months after seizing the three laptops encrypted with BitLocker. [...] Microsoft told Forbes that the company sometimes provides BitLocker recovery keys to authorities, having received an average of 20 such requests per year.
