Adversary-in-the-middle attacks have risen sharply, with a notable 2022 incident where over 10,000 credentials were stolen from numerous organizations, including Twilio. However, the cloud service provider Cloudflare remained secure due to its use of MFA based on the WebAuthn standard, which provides strong protection. The technology binds credentials to specific URLs and user devices, making phishing attempts via unauthorized sites ineffective. This distinguishes WebAuthn from traditional MFA methods, which are increasingly vulnerable to modern phishing tactics and proxy attacks, highlighting the importance of adopting more secure authentication methods.
Adversary-in-the-middle attacks are increasingly common, exemplified by a 2022 incident where one group stole over 10,000 credentials from 137 organizations, compromising Twilio.
WebAuthn credentials authenticate to specific URLs, making them resistant to adversary-in-the-middle attacks, as a victim cannot use credentials on ulterior sites like evilproxy.
WebAuthn's design, binding credentials to both the specific site and the user's device, renders them immune to phishing attempts, enhancing security substantially over older MFA methods.
MFA via one-time passwords and push notifications aids in phishing defense; however, they are more easily compromised compared to WebAuthn, due to rising proxy-in-the-middle attacks.
