Fly.io's CEO fell victim to a sophisticated phishing attack that compromised their Twitter account for 15 hours. The attacker exploited psychological vulnerabilities by sending a fake alert about a questionable post, prompting the CEO to log in through a fake domain. The incident highlights why phishing-resistant authentication (like FIDO2 and Passkeys) is essential, as training alone cannot prevent all phishing attempts. The company's infrastructure remained secure because it uses SSO with phishing-proof MFA, but their Twitter account was a legacy shared credential managed through 1Password. The attack resulted in a crypto scam post and temporary brand damage, but no user data was compromised.
