Less is safer: How Obsidian reduces the risk of supply chain attacks

Supply chain attacks are malicious updates that sneak into open source code used by many apps. Here’s how we design Obsidian to ensure that the app is a secure and private environment for your thoughts. Less is safer It may sound obvious but the primary way we reduce the risk of supply chain attacks is to avoid depending on third-party code. Obsidian has a low number of dependencies compared to other apps in our category. See a list of open source libraries on our Credits page. Features like

After a very slow start, Europe’s reusable rocket program shows signs of life

No one could accuse the European Space Agency and its various contractors of moving swiftly when it comes to the development of reusable rockets. However, it appears that Europe is finally making some credible progress. This week, the France-based ArianeGroup aerospace company announced that it had completed the integration of the Themis vehicle, a prototype rocket that will test various landing technologies, on a launch pad in Sweden. Low-altitude hop tests, a precursor for developing a rocket

Two UK teens charged in connection to Scattered Spider ransomware attacks

Federal prosecutors charged a UK teenager with conspiracy to commit computer fraud and other crimes in connection with the network intrusions of 47 US companies that generated more than $115 million in ransomware payments over a three-year span. A criminal complaint unsealed on Thursday (PDF) said that Thalha Jubair, 19, of London, was part of Scattered Spider, the name of an English-language-speaking group that has breached the networks of scores of companies worldwide. After obtaining data, t

Northrop Grumman successfully resupplies ISS after overcoming software glitch

Running a day late, Northrop Grumman's Cygnus XL cargo freighter pulled alongside the International Space Station on Thursday, delivering more than 5 tons of supplies and experiments to the lab's seven-person crew. NASA astronaut Jonny Kim took control of the space station's robotic arm to capture the Cygnus spacecraft at 7:24 am EDT (11:24 UTC) on Thursday. A short time later, the robot arm positioned the spacecraft over an attachment port on the station's Unity module, and 16 bolts drove clos

NordVPN vs. Surfshark: See How These Sister Services Stack Up

James Martin/CNET NordVPN and Surfshark are two of the best virtual private network providers on the market, and while they share some similarities -- including the same parent company -- each packs unique offerings. NordVPN is our pick for the fastest VPN, based on our hands-on testing, while Surfshark earns our vote for the best value VPN. Both VPNs deliver fast speeds, user-friendly apps, handy privacy features and excellent streaming service content unblocking. Overall, I’d recommend Surfs

A pivotal meeting on vaccine guidance is underway—and former CDC leaders are alarmed

On Thursday, an advisory CDC panel that develops vaccine guidance met for a two-day discussion on multiple childhood vaccines. During the meeting, which was underway as The Checkup went to press, members of the panel were set to discuss those vaccines and propose recommendations on their use. Monarez worries that access to childhood vaccines is under threat—and that the public health consequences could be dire. “If vaccine protections are weakened, preventable diseases will return,” she said.

A better future for JavaScript that won't happen

In the wake of the largest supply-chain attack in history, the JavaScript community could have a moment of reckoning and decide: never again. As the panic and shame subsides, after compromised developers finish re-provisioning their workstations and rotating their keys, the ecosystem might re-orient itself towards solving the fundamental flaws that allowed this to happen. After all, people have been sounding the alarm for years that this approach to dependency management is reckless and dangero

Two teenagers charged over Transport for London cyber attack

Two teenagers charged over Transport for London cyber attack Two teenagers have been charged as part of a National Crime Agency (NCA) investigation into a cyber attack on Transport for London. TfL suffered a major hack on 31 August last year, which investigators believe was carried out by members of the cyber-criminal group, Scattered Spider. Thalha Jubair, 19, from east London, and Owen Flowers, 18, from Walsall in the West Midlands, were arrested at their home addresses on Tuesday by the NC

The DOGE Subcommittee Hearing on Weather Modification Was a Nest of Conspiracy Theorizing

“What this whole debate comes down to is who controls the skies,” Republican representative Marjorie Taylor Greene of Georgia told the audience at a House Oversight Committee hearing on Tuesday. “Do we believe in God and that he has dominion over his perfect creation of planet Earth? Do we believe that he has given us everything we need to survive as a civilization since the beginning of time? Or do you believe in man’s claim of authority over the weather, based on scientists that have only been

Something Weird Is Going on With the Sun, Scientists Find

The Sun — usually so predictable — is exhibiting some surprising behavior and that has scientists very intrigued. Astronomers had predicted that our host star was entering a period of relative quiet back in 2008, but NASA scientists have published a new study in The Astrophysical Journal Letters that found that the Sun has instead defied expectations by becoming more active, with increased sunspots and solar flares. "All signs were pointing to the Sun going into a prolonged phase of low activi

Anthropic Wants to Be the One Good AI Company in Trump’s America

Anthropic, the artificial intelligence company behind the chatbot Claude, is trying to carve out a spot as the Good Guy in the AI space. Fresh off being the only major AI firm to throw its support behind an AI safety bill in California, the company grabbed a headline from Semafor thanks to its apparent refusal to allow its model to be used for surveillance tasks, which is pissing off the Trump administration. According to the report, law enforcement agencies have felt stifled by Anthropic’s usa

From Qubits to Qubucks: Quantum Digital Currency

Quantum computing is often discussed in terms of its potential to revolutionize scientific discovery and to challenge cryptographic paradigms [1], but it could also change our relationship with money. By using quantum states, quantum currency could solve the double-spending problem and address throughput issues associated with distributed ledgers (blockchain), paving the way for the digital cash of the future.

Firefox 143 for Android to introduce DoH

All web browsing starts with a DNS query to find the IP address for the desired service or website. For much of the internet’s history, this query is sent in the clear. DNS-over-HTTPS (DoH) plugs this privacy leak by encrypting the DNS messages, so no one on the network, not your internet service provider or a free public WiFi provider, can eavesdrop on your browsing. In 2020, Firefox became the first browser to roll out DoH by default, starting in the United States and in 2023, we announced

Stop Letting That Old Computer Gather Dust. Here's Where to Recycle It for Free

When an old laptop or printer finally gives out, the biggest question is often, "What do I do with it now?" Tossing electronics in the trash is bad for the environment and can even be illegal. It's no wonder a recent CNET survey found that nearly a third of us have old, unused tech just sitting in our closets and basements. The good news is that recycling your e-waste is simpler than you might think. You don't have to hunt down a special facility; major retailers like Best Buy and Staples make

A record supply load won’t reach the International Space Station as scheduled

A problem with the main engine on Northrop Grumman's Cygnus XL spacecraft will keep it from delivering 11,000 pounds of supplies and experiments to the International Space Station as scheduled on Wednesday. In a statement released Tuesday afternoon, NASA said ground teams are evaluating backup plans that might still allow the Cygnus spacecraft to reach the space station, just not on schedule. The problem arose early Tuesday when the spacecraft's main engine shut down earlier than expected durin
