Unfortunate way to learn that SMS 2FA/MFA isn't adequate, especially when TOTP is available. Unfortunate way to learn, Not Your Keys, Not Your Coins. That being said, Valve has a higher level of security on my Stream account than Coinbase has. With Steam, a password reset triggers a 5 day marketplace/trading suspension.
I presume from the article an email account was hacked (password available?), which gave means for a Coinbase password reset, and then a SIM swap occurred on his account leading to a withdrawal.
One might argue Coinbase has a duty to do more here -- nothing on their site (at least the security/mfa section) suggests SMS isn't good enough. PcMagazine[1] suggests 95% of users rely on SMS 2FA/MFA, and Coinbase seems aware that these phishing campaigns are happening against SMS 2FA/MFA [2].

- wmf 4y agoUsually they do the SIM swap first, use SMS to recover email, then use email+SMS to recover Coinbase. I agree that Coinbase could do more.
