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.
On top of all the other good answers, someone can also just SIM hijack your phone number by social engineering your phone provider into activating a new SIM card.
And it’s usually much easier than one would think/hope.
I’m convinced, will switch to app authentication.
Make sure you backup your vault and/or keep the backup “paper codes” somewhere safe.
Aegis, for example, can automatically backup an encrypted vault.
