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

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.

Aegis Authenticator, in case someone was wondering what to use

I'm not that tech savy, so I was under the impression sms 2FA was the best way to go - why is app based authentication better?

Cause SMS is not encrypted, so your phone provider and any routing company like this one can read your texts, phone numbers can be spoofed (not sure about this one), or stolen via social engineering (someone calls your phone provider claiming it's you and u lost your phone or something, then gets access to your number).

There's probably a lot more issues with it, i don't remember them atm, but should be pretty easy to find with a search if you're still curious.

Also, physical phone stolen, and the thief just pops the simcard out and puts it in another phone.
