At least one US federal agency was infected with a backdoor as part of a widespread China-linked espionage campaign targeting Cisco firewalls. In May 2024, Cisco patched two vulnerabilities in its Adaptive Security Appliance (ASA) firewall platform that had been exploited as zero-days in a state-sponsored campaign tracked as ArcaneDoor. A year later, the company fixed two more zero-days linked to the same campaign, tracked as CVE-2025-20333 and CVE-2025-20362, and impacting the VPN web server of ASA and Secure Firewall Threat Defense (FTD) software. In September 2025, the US cybersecurity agency CISA issued Emergency Directive 25-03 (ED 25-03), urging federal…

The Dylan Patel, head of Semianalysis, interview is a must watch for anyone tracking AI economics, infrastructure, and future societal shifts. SemiAnalysis’s own AI spend exploded from tens of thousands last year to $7 million annualized run-rate right now. Even non-technical staff are now heavy Claude/Code users. Semianalysis metrics and work are cited by Nvidia CEO Jensen Huang at his keynote address. One person spent a couple thousand dollars to build a GPU-accelerated chip reverse-engineering dashboard that previously required an entire Intel team. Economist Malcolm single-handedly built a full US energy-grid mapping + regression analysis + 2,000-task AI-impact benchmark in…

My original Switch should feel retired by now. It has the thick bezels, the aging screen, the tired battery life, and the unmistakable aura of a gadget that has survived too many backpacks. Next to Switch 2 and the current wave of handheld PCs, Nintendo’s first hybrid console looks hopelessly outgunned. And yet, I keep picking it up. My standards are not heroic here. I want to wake it and start playing before the part of my brain that checks battery percentages gets involved. I use the old console in 2026 because it’s almost annoyingly direct. That shouldn’t feel radical.…

I received a Google Nest Hub as part of a promotion with a Google One subscription, and for years, it was the organizational center of my smart home setup. It handled timers and alarms, answered quick questions, streamed news, music, and podcasts, and reminded me of calendar appointments and events when I woke. What it lacked, however, was flexibility — it did what it was designed to do, but that was about it. This limitation became more obvious as my requirements evolved. As I started to travel more for work and leisure, I needed better customization, more app support, and,…

We rarely come across two phones that are so similar. The newly launched Google Pixel 10a is unapologetically more or less the same phone as its predecessor, the Pixel 9a. This leaves those looking for an affordable Pixel this year in a quandary. Should you go for the newer model, or should you just save some money and get last year’s. And what even are some of these minor differences that separate the two? Well, let’s find out. Table of Contents: For starters, you can compare the complete specs sheets or directly continue with our editor’s assessment in the following…

A newly uncovered APT is relying on legitimate services for command-and-control (C&C) communication and data exfiltration, ESET warns. Tracked as GopherWhisper (PDF) and active since at least November 2023, the hacking group is operating out of China, as timestamp inspection of chat messages and emails has revealed. The APT came to the spotlight in January 2025, during the investigation into a Go-based backdoor found on the systems of a governmental entity in Mongolia, which led to the identification of several other backdoors, custom loaders, and injectors associated with the group. Dubbed LaxGopher, the backdoor uses Slack for C&C communication and…

Listen to this audio excerpt from Peter Rossoni, Orion Artemis II Optical Communications System flight manager: Your browser does not support the audio element. As a child, Peter Rossoni watched the Apollo missions launch with his family. In April 2026, he became a part of NASA’s Artemis II mission, helping enable communications as astronauts journeyed around the Moon. Rossoni’s path to NASA began as he followed his parents’ footsteps into science. That foundation eventually led him to laser communications and NASA’s Artemis II test flight. Today, Rossoni is the flight manager for the Orion Artemis II Optical Communication System at…

Kaitlyn Cimino / Android AuthorityKindle users have an old complaint that resurfaces every time a popular book gets a screen adaptation. One day, you open your library expecting a familiar cover and instead, find yourself staring at a glossy movie version. I have a cinephile brother who assigns me reading material the second a book’s rights are bought, so over time, my library has started to look like a movie theater hallway. Fortunately, there’s one way to avoid the same fate. Do you like movie-based book covers on your Kindle?0 votesNo, I hate them.NaN%Yes, I actually prefer them.NaN%I don’t mind…

The world’s largest live-fire cyber defense exercise, Locked Shields 2026, concluded on Friday after bringing together more than 4,000 participants from 41 nations.  Organized by the NATO Cooperative Cyber Defence Centre of Excellence (CCDCOE) in Tallinn, Estonia, the event simulated intense real-time cyberattacks against critical infrastructure and military systems, testing defenders’ ability to maintain essential services under pressure. The number of participants was the same as in 2025. Teams were tasked with protecting air defense, e-voting platforms, and other critical infrastructure. In addition to technical skills, Locked Shields tests the ability to deal with disinformation and political pressure. According to…
