  • Dark Reading ☛ How Has IoT Security Changed Over the Past 5 Years?

    While organizations increasingly use IoT devices and applications to improve operational efficiency or save money, the technology is inherently insecure. It makes everything more connected, leaving a treasure trove of [Internet]-exposed data. On top of that, many IoT devices are not equipped to receive easy vulnerability patching updates, or even alerting users that any update is needed.

    Manufacturers ship devices with simple default passwords such as "admin admin" and many users don't know they need to be reset to strengthen security. This is especially critical, as attackers have become more competent in the IoT space.

  • Linux Gizmos ☛ M5Stack Introduces Cardputer-Adv with Expanded Features and Higher-Capacity Battery

    It is powered by the Stamp-S3A core module based on the ESP32-S3FN8 dual-core Xtensa LX7 processor, running at up to 240 MHz with 8 MB of flash storage. A microSD card slot provides additional storage for applications and data, and an infrared emitter is included for remote-control functions.

  • Linux Gizmos ☛ Pi Zero 2 W AV-USB board adds USB hub, audio, and video output

    The AV-USB provides three full-size USB-A ports via an onboard hub, along with a PCM5102-based stereo analog audio interface over I2S. Audio and composite video are routed through a 3.5 mm TRRS jack, restoring analog video output that on the Pi Zero 2 W was moved to a small test pad, making it easier to connect displays without soldering.

  • Hackaday ☛ Dialing It In: A 3D-Printed Knob With Touchscreen Flair

    Knobs are ubiquitous in technology user interfaces, but touchscreens are increasingly replacing them for interface controls. The latest project from [upir] combines a rotating knob with a touchscreen for a stunning result. The knob-over-display design features a touchscreen where you can place and remove a spinning knob, creating an interface reminiscent of Microsoft’s Surface Dial but at a fraction of the cost.

  • Hackaday ☛ Psst… Got A Second? Here Are The 2025 One-Hertz Challenge Winners

    Even with teachers with names like Kirchhoff and Helmholtz, old Heinrich Hertz himself likely didn’t have the slightest idea that his name would one day become an SI unit. Less likely still would have been the idea that Hackaday would honor him with the 2025 One-Hertz Challenge.

  • Osservatorio Nessuno ☛ Bugbane: Simplifying consensual Android forensics

    In this blog post, we introduce Bugbane, an open-source Android app that makes consensual mobile forensics more accessible by leveraging Android’s local ADB service. We explain how it builds on tools like MVT and AndroidQF, guiding users through acquisitions and malware checks directly on their devices. We also highlight its reproducibility, secure export features, and our call for community feedback as development continues. Bugbane is still in early testing and not yet ready for general end-user release. Check out the GitHub repository.
