How could that even be possible? Short of PayPal having a hole in their 2FA implementation, it's very difficult for me to imagine how this could happen. I mean, unless the hackers logged in, left the 2FA prompt up and then a user completed the 2FA exchange, but that would be a foolish thing to do anyway... edit: thanks for the answers; makes sense!

Presumably the 2fa is just for the login, and the user would already be logged into paypal on their computer. Your paypal account getting hacked isn't a Big Deal, you aren't going to lose any money over it. In fact, managing that is paypals entire business model.

I believe they were saying that they have 2FA on TeamViewer, not on PayPal.

This is referring to TeamViewer's 2FA, not Paypal's 2FA

I'm guessing 2FA here refers to TeamViewer's 2FA, not PayPal's 2FA.

  Yeah, sorry, that was confusing. I don't really agree with the comments saying that the comment was referring to TV's 2FA. I agree with fapjacks/ryanlol's comments. I (think I) now understand why "and my PayPal has 2FA enabled" points to TV being compromised -- If the PayPal account has 2FA active, and they were still "hacked", then it points to an existing session being hijacked. And a probable cause of that would be a compromised TV session. So it's not necessarily an indication that TV's 2FA was compromised, but rather that TV was compromised in general, allowing the hacker to hijack TV sessions. (I'm imagining that the TV 2FA happens on their central server, and not on the actual server daemon running on the target remote machine... so if the central server was compromised...) edit: Obviously this is entirely speculative, I don't know any of what's going down, but it resolves my initial curiosity.
