Canada’s Bill C-2 is a Trojan horse, being pushed to align with U.S. surveillance demands. EFF joins the CCLA, OpenMedia & Citizen Lab in saying: Withdraw it. eff.org/deeplinks/2025/07/cana

My story from Monday is here:

arstechnica.com/security/2025/

In short, the attack as originally described simply would not work against a FIDO2-compliant authentication system. Whatever system the researchers analyzed used a non-FIDO2 fallback in the event the user was unable to provide FIDO2-MFA. Calling this a bypass is like saying a door lock is insecure because an intruder could enter through a window. Lots of publications continue even now to say this was a bypass. It wasn't.

@dangoodin THANKS for covering this! I was frustrated when I read about it. The FIDO2 specification explicitely describes this exact scenario. Big oversight on them for not understanding the FIDO2 spec.

@spzb like meta does not need to do this at all, the benefit would not outweight the risk and cost! 🤷‍♂️

@blond11516 It's such a popular conspiracy it's kind of frustrating

@blond11516 if there is no LED, you still need to display a green dot. This is required by Android and enforced to manufacturers

And if you don't have an always-on display, it's trivial to open settings and see that facebook did not, in fact, use the microphone

This misinformation sucks. When an app uses the microphone on Android, even a background app, the operating system turns a little LED above your screen on to let you know something is listening. I have never seen this open when my phone was closed and have not seen any credible report of it happening. Just anecdotes of people who don't understand that if you meet a friend and that friend has a new hobby and you talk about it and you see ads of it, it's not because of the mic, it's because facebook saw that you met that friend and the chances you talked about this is high.

We don't need to create false conspiracies to hate on Meta, there is enough real stuff already.

Version 10.1.8 is out and is not infected. If you have the capability, hunt for node-gyp.dll, it's the malicious DLL.

Widely used NPM package eslint-config-prettier has been compromised is dropping windows malware. Version 10.1.6 and 10.1.7 impacted. Beware!
