Modern devices contain 10-15 processors running closed firmware, from keyboards to storage drives, leaving users dependent on manufacturers for security updates and repairs. This creates e-waste through forced obsolescence, enables vendor lock-in through cloud dependencies, and prevents users from modifying devices they own. The author argues developers must publish firmware sources, use copyleft licenses like GPL, demand open documentation, and support political movements for right to repair and device freedom. 71 6 2. 2 [](/posts/root-shell-on-credit-card-terminal-qxlvvrzwx "Root Shell on Credit Card Terminal") Article Hacker News · 1y Root Shell on Credit Card Terminal A security researcher reverse engineered a Worldline Yomani XR payment terminal and discovered an exposed root shell accessible via serial console without authentication. Despite sophisticated tamper detection mechanisms using pressure-sensitive connectors and copper traces, the debug interface remained accessible through an external hatch. The researcher extracted unencrypted firmware using chip-off techniques, revealing an outdated Linux system (kernel 3.6 from 2023). However, the security impact is limited because the Linux system only handles networking and updates, while sensitive payment operations run on a separate, encrypted secure processor. 57 3 3. 3 [](/posts/air-lab-simulator-wkr6azzzr "Air Lab Simulator") Article Hacker News · 1y Air Lab Simulator A web-based simulator that replicates Air Lab firmware functionality, allowing users to interact with virtual environmental sensors through different simulated environments. The simulator includes device controls, USB connectivity simulation, and menu navigation features, providing a hands-on experience without requiring physical hardware. 51 1 [See all Firmware archives](/tags/firmware/best-of) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/tags/firmware/best-of/2025#page","url":"https://daily.dev/tags/firmware/best-of/2025","name":"Best Firmware Posts of 2025","description":"The most upvoted Firmware posts of 2025, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/tags/firmware/best-of/2025#items","numberOfItems":3,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/free-software-hasn-t-won-xhes61n7u","name":"Free Software hasn't won"},{"@type":"ListItem","position":2,"url":"https://daily.dev/posts/root-shell-on-credit-card-terminal-qxlvvrzwx","name":"Root Shell on Credit Card Terminal"},{"@type":"ListItem","position":3,"url":"https://daily.dev/posts/air-lab-simulator-wkr6azzzr","name":"Air Lab Simulator"}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Tags","item":"https://daily.dev/tags"},{"@type":"ListItem","position":3,"name":"Firmware","item":"https://daily.dev/tags/firmware"},{"@type":"ListItem","position":4,"name":"Best of","item":"https://daily.dev/tags/firmware/best-of"},{"@type":"ListItem","position":5,"name":"2025"}]}]} ```
