To set a scene, you awake in the middle of the night because your phone is making noise. Blearily you unlock it, glance at a prompt, and then approve a login and fall back asleep. The intruder now has access to your password manager!
They attempt to log into your bank and drain your life savings, but despite having your password it sends another prompt to your phone. This time, you wake up enough to realize something is wrong. This time, you deny the prompt.
The entire second paragraph cannot happen if your MFA is a single factor. Don’t store MFA in your password manager!
Bruh, if my phone is sending me notifications in the middle of the night, the first thing I’m doing is uninstalling whatever app is sending me notifications.
If people are that gullible to fall prey to an attack like this, managing OTP in two apps is probably more than they can handle anyway. Everybody has a different threat model, and it’s okay if it’s not covered by hardware passkeys and locally hashed and managed databases.
Blearily you unlock it, glance at a prompt, and then approve a login and fall back asleep.
The idea that people would approve that is wild to me.
Mate, I’ve had users who were sharing an account that only some of them had MFA prompts for. They didn’t bother checking who had initiated the prompt, they just approved it because it was easier. And that was while they were fully awake and thinking…
What’s funny to me is that doing this while you know your target is asleep probably has a higher success rate just because they’re more likely to press the wrong thing just because their eyes are groggy. I can read my phone without my glasses but when I wake up in the night that’s not the case right away.
