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 great recommendation to use app-based 2FA, except that lots of services seem to insist on and only offer SMS OTP.

    For instance out of all the financial establishments I do business with, only one offers the option. The big name players don’t, it’s only some tiny little mom & pop CU that does.

    It’s very much a business adoption issue.

      App-based is also unacceptable if it’s a proprietary implementation

      TOTP/HOTP are the best standards right now

          Yeah, Yubikey fits - it implements TOTP/HOTP, and bitwarden is great

          Just “app-based” worried me about apps rolling their own implementations instead of using standards

        Have you ever used HOTP before? Convenience-wise, it’s much worse than TOTP. It’s not supported by popular apps, you can’t use it on several devices unless there’s synchronization, you never know if the code you’re looking at was used already.

          Yeah, it’s much less convenient. I prefer TOTP, but I will pick HOTP over Cisco Duo’s proprietary implementation that I can’t use without their specific app if those are my only options

      Not sure if you do business with them, but Charles Schwab does have a app-based MFA option - although that’s limited to Symantec’s own TOTP MFA.

        A lot of sites say they only support one specific MFA app. But in my experience, any MFA app that can read the QR code will work.

        I don’t know how/if I could generally cite my sources, because I’m just anecdotally referring to the services that I happen to use, that offer 2FA, but restrict it to SMS or email delivery. It’s purely my experience that the most important services I use (banking, investment, utilities) are commonly the ones that don’t offer the ability to use an app for 2FA.

                Bro, I literally don’t even understand your malfunction, lol. I don’t at this point even know what I said you think is so wild. Lots of really important businesses and services still only allow for for SMS or email OTP delivery. If you find that for the most part that sentiment doesn’t apply to you because your day to day account spread differs, more power to you.

                  There seems to be a trend with certain people of always asking to “cite your sources” on every goddamn thing. Then when you refuse, they’ll trot out “extraordinary claims require extraordinary evidence”, and your only claim is that you bought a sandwich yesterday.

                  Worst way to “win” an Internet fight.

                    You’re either playing a fool to try to rustle my jimmies, or you genuinely have exceeded your FRESHEST IF USED BY date. It bores me, so I’m just going to block you.

                Nor should anyone, especially when you accuse anyone who questions you with lying simply for challenging your position.

                Nah, his responses are fine. The real problem here is just that you lack reading comprehension skills and are being a jerk for no reason.

                It’s funny how you don’t realize that you’re describing yourself to everyone else while talking with someone who is clearly much more inform that you could ever hope to be.

                You don’t need to go agro over someone’s anecdotal comment. Makes you look like an unhinged idiot.

                    Not really, just tired of seeing ignorant comments posted by unhinged idiots who don’t know what they’re talking about in regards to a field I’m rather knowledgeable in.

                    In the end, I don’t care what you think because you’re wrong and very obviously uninformed, and just lashing out at people smarter than you who aren’t willing to spoon-feed you information you could easily Google based on, again, a comment that was explicitly anecdotal.

                    If you had put forth even a modicum of your own effort instead of acting unhinged, you would have seen that this is a common complaint about financial institutions. But keep going off on uneducated and uninformed rants, makes you look suuuuuuuper smart.

        When you see “cite your sources” shit like this, please just block the user instead of arguing with them. So tired of these pricks. A person like this has no interest in seeing your sources, they just want to argue with anyone about anything.
