Specter-FlipperZero v2.8

The waveform is not a graphic. It is 128 columns of 13.56 MHz carrier that Specter recorded off a real polling reader at 8 ms per column, read back out of the screenshot beside it. Its duty measures 28% where the device's own counter printed 27%, and both numbers are on the banner. Sweep for the...

Beyond the Trust Boundary: A Critical Reassessment of the FIDO2 Threat Model

FIDO2/WebAuthn has been widely deployed as a phishing-resistant authentication scheme. Because FIDO2 relies on public-key cryptography and hardware-backed authenticators, its security is often assumed to be guaranteed by design, provided that the cryptographic implementation is correct. In this...
