Tech Company Leaks 2FA Codes/Password Reset Links for Major Platforms (techcrunch.com)

submitted 8 months ago by [email protected] to c/[email protected]

75 comments fedilink hide all child comments

A security breach exposed two-factor authentication (2FA) codes/password reset links for millions of users on platforms like Facebook, Google, and TikTok.

Key Points:

YX International, an SMS routing company, left an internal database exposed online without a password.
The database contained one-time 2FA codes and password reset links for various tech giants.
YX International secured the database and claims to have "sealed the vulnerability."
The company wouldn't confirm how long the database was exposed or if anyone else accessed it.
Representatives from Meta, Google, and TikTok haven't commented yet.

Concerns:

This leak highlights the vulnerabilities of SMS-based 2FA compared to app-based methods.
The lack of information regarding the leak's duration and potential access by others raises concerns.

Gemini Recommendations:

Consider switching to app-based 2FA for increased security.
Be cautious of suspicious communications and avoid clicking unknown links.
Stay informed about potential security breaches affecting your online accounts.

It's a circus out there...

One of my financial institutions supports yubikeys, but does not have the option to turn off sms 2fa. A chain is as strong as the weakest link, as usual.

Another only has sms 2fa and bizarrely allows me to specify any phone number at login time to receive the code. WTF?

Most only have 2fa via sms. When you talk about using an authenticator app people bitch and moan because they have to cut and paste those digits into the login page. Oh, the humanity...

Don't even get me started on sites with "roll your own" schemes, like forcing you to install their app (which requires all permissions under the sun) just to accept a push message and allow you to login on their website.
