Database leak exposes millions of two-factor codes and reset links sent by SMS
Millions of SMS text messages—many containing one-time passcodes, password reset links, and plaintext passwords—were exposed in an Internet-accessible database that could be read or monitored by anyone who knew where to look, TechCrunch has reported.Password breach teaches Reddit that, yes, phone-based 2FA is that bad
The discovery comes after years of rebukes from security practitioners that text messages are a woefully unsuitable medium for transmitting two-factor authentication (2FA) data. Despite those rebukes, SMS-based 2FA continues to be offered by banks such as Bank of America, cellular carriers such as T-Mobile, and a host of other businesses.
The leaky database belonged to Voxox, a service that claims to process billions of calls and text messages monthly. TechCrunch said that Berlin-based researcher Sébastien Kaul used the Shodan search engine for publicly available devices and databases to find the messages. The database stored texts that were sent through a gateway Voxox provided to businesses that wanted an automated way to send data for password resets and other types of account management by SMS. The database provided a portal that showed two-factor codes and resent links being sent in near real-time, making it potentially possible for attackers who accessed the server to obtain data that would help them hijack other people's accounts.

Yes, and several of my colleagues have explicitly requested such. But the problem is that many of us "modern" faculty post grades, or even post things like announcements and assignments, online these days, and if I can only log in to the University's system when I have a secondary verification, like my office landline, that means I cannot enter grades without having to actually come in to my office. Yes, First World Problem. But as I said, after they sold out our email to the corporation that "formerly" would not be evil, well, I have to wonder. And I am on the "do not let my boss call" list.

What's the chance you can set your office landline* to forward to your cell phone? A slight pain to punch in some numbers before you leave the office, but much easier than a separate trip to the office. At least this way, Google doesn't have your cell number.
* It's probably not a traditional landline with dumb switching/exchange, more likely it goes to a computer switch somewhere near campus.
