Core YubiKey functions The FIDO2 U2F security key is designed to be placed in a USB port or via NFC with your smartphone and works with any website that supports the FIDO2 U2F protocol, including Facebook, Google’s Gmail, Google Cloud and G Suite, GitHub, Dropbox and Dashlane. User names and passwords are no longer sufficient to protect access to online accounts. The FIDO2 U2F NFC security key from Yubico is a specially designed YubiKey, which relies on high security public key cryptography to provide strong authentication. If a vehicle owner normally uses the phone app to unlock the car-by far the most common unlocking method for Teslas-the attacker can force the use of the NFC card by using a signal jammer to block the BLE frequency used by Tesla's phone-as-a-key app.Are you worried about losing account data due to theft of passwords, phishing, hacking or keylogging scams? Now there is less to worry about. ![]() (The researcher plans to release a benign version of Teslakee eventually that will make such attacks harder to carry out.) The attacker then uses the Teslakee app to exchange VCSec messages that enroll the new key.Īll that's required is to be within range of the car during the crucial 130-second window of it being unlocked with an NFC card. ![]() So the researcher built his own app, named Teslakee, that speaks VCSec, the same language that the official Tesla app uses to communicate with Tesla cars.Ī malicious version of Teslakee that Herfurt designed for proof-of-concept purposes shows how easy it is for thieves to surreptitiously enroll their own key during the 130-second interval. The official Tesla phone app doesn't permit keys to be enrolled unless it's connected to the owner's account, but despite this, Herfurt found that the vehicle gladly exchanges messages with any Bluetooth Low Energy, or BLE, device that's nearby. ![]()
