Polyfill.io torna attivo nel 2026: pop-up di login sospetti colpiscono Toshiba, Muji e Samsung
Il dominio polyfill[.]io è tornato attivo a fine maggio 2026 rispondendo con HTTP 401, inducendo i browser a mostrare false richieste di autenticazione agli utenti di Toshiba, Muji, Zojirushi e Samsung. Una coda dell'incidente di supply chain del 2024 che colpisce chi non aveva completato la pulizia del codice.
#TVSMART #samsung - Tornano le rogne da #polyfill.io già sperimentate nel 2024.
L' #IoT sta diventando un campo ad alto contenuto di seccature.
L'applicazione HbbTV del gruppo Mediapason richiama una vecchia libreria che è stata usata negli ultimi anni per truffe e raggiri. Da qualche giorno quella libreria mostra un popup a chi prova a collegarsi al dominio: i TV Samsung, su determinati canali, si bloccano. Ecco come risolvere ma soprattutto, e ben più grave, cosa c'è dietro.

We rolled out adaptive light-dark() support on our design system themes and it’s been a delightful upgrade. Creating light and dark variable sets isn’t difficult, but delivery has trade-offs. Most apps that do this probably ship both sets of token values in a single stylesheet. That’s fine until you have multiple kilobytes of duplicate definitions. To get around the performance problems we built two separate stylesheets –which is also not great– but my coworker Zacky found a good trick with <link disabled> to make it tolerable. Ultimately, we wanted to offer a single stylesheet for our human (and agent) friends to control theming.

Introducing view-transitions-mock, a non-visual polyfill for same-document view transitions. @bramus built a spec-compliant JavaScript implementation of the View Transition API that works across all browsers. It handles document.startViewTransition(), the ViewTransition class with its promises, and view transition types. Animations are skipped in unsupported browsers, but DOM updates work as expected. #viewtransition #polyfill
