    For decades, Canadians eagerly rushed onto US tech platforms and services. But now the drawbacks of that dependence are on full display.For the Canadian Centre for Policy Alternatives, I explain the economic and political consequences of a US-dominated internet — and why digital sovereignty is imperative.https://www.policyalternatives.ca/news-research/every-data-centre-is-a-u-s-military-base/#tech #canada #cdnpoli #cdntech #digitalsovereignty #politics

    The "Bluetooth Headphone Jacking" talk at #39c3 was awesome, too. They reversed a popular SOC that powers Bluetooth earbuds and headphones.They found that (even without being paired to the headphone), they could dump flash and RAM from the device. Then they dumped a bunch of info from the device - e.g. the #Bluetooth address and "master" encryption keys used for the communication with paired devices (e.g. a #phone).Then they impersonated the headphone from their laptop and connected to the phone (pretending to be the headphone).The headphone (or the laptop impersonating the phone) has permissions to do some things on the phone, e.g. accept calls, increase/decrease volume, etc.Then they started recovering access a #WhatsApp account via some account recovery mechanisms. That required some one-time security key which would normally be delivered via SMS, but that could be delivered via phone call as a fallback option, too. Since the phone thought it was connected to the Bluetooth headphone, phone call audio would go to the laptop via Bluetooth.As the cherry on top, they escalated into the victim's #Amazon account.Scary shit. #YouCannotBeParanoidEnough #security

    @rriemann sponsored the first #EU_OS stickers to let people show their support. A few will go next week to The Hague 🇳🇱 and even more later to #39c3 in Hamburg 🇩🇪 and #fosdem26 in Brussels 🇧🇪.Unfortunately they come too late for the summit this week in Berlin #eusummit25.

    @MeaningfulBits it will ease things for Binance establishing more of a US presence, and for the Trumps in doing business with them. it could also potentially help CZ return as CEO to Binance
