Passkeys aren’t attack-proof, not until properly implemented

“We used the usual GitHub phishlet that may be present in numerous person repositories on GitHub itself,” Stewart mentioned. “When the focused person visits the lure URL, aside from the hostname within the URL bar, what they may see seems to be similar to the traditional GitHub login web page, as a result of it’s the precise GitHub login web page, simply proxied by Evilginx.”

Nevertheless, by barely modifying the usual phishlet configuration, we are able to take away the “Check in with a passkey” textual content, Stewart added demonstrating how simply a person may be tricked into selecting a backup, password-based authentication.

The research famous that these sorts of assaults may be staged for circumstances the place passkeys are used as the primary issue in addition to the second-factor authentication methodology. “Except the person particularly remembers that they need to see a passkey possibility, they may more than likely merely enter their username and password, which might be despatched to the attacker together with the authentication token/cookies, which the attacker can use to take care of persistent entry to the account,” Stewart added.
