Hardware

Designed for securing online accounts, FIDO U2F as a protocol and YubiKey as a hardware tool are not silver bullets. If not used wisely, this powerful combo becomes an attractive target in the hands of skilful attackers.

NFC-based devices, such as mobile digital wallets, contactless smart cards, and security keys (hardware authentication devices), are exposing users to NFC vulnerabilities in encryption, replay and side-channel attacks.

Stunned by losing their robotic devices, [REDACTED] learnt that they were hijacked by attackers even with communication being encrypted. Having researched its firmware and found numerous cryptographic failures, we've crafted a few demos on how cryptography goes wrong in real life.
