It's looking like you got phished a long time ago, or installed malware which targeted the lastpass extension.
Did all of you use the same OS four years ago? (Windows perhaps?) Some malware targets Chrome/Firefox files on disk. A malicious extension probably wouldn't be able to affect your LastPass extension, but a malicious malware app could easily modify it.

Yeah, all of us being phished years ago is a possibility (I just replied to your other comment)
I used macOS/Chrome back in 2017. I definitely could have been phished then, or used a compromised extension.

How'd they get past the 2FA, though?
Or does LP shoot an email if it detects a suspicious geo-IP login before the 2FA prompt?

LP shoots an email as soon as someone attempts to login with the correct password from a new IP.
Once the IP is approved (you have to follow a link from the email), then you login again with the correct password and then get the 2FA prompt.
Since I haven't used this LastPass master password since 2017, I'd have to remember which extensions I had back then, which is hard to do...
I may have had 1Password and Adblock Plus which you had/have too.
But it's hard to say. It's a possible vector (that you, dogman123 and I had the same compromised extensions) but also... why would the hackers have sat on our master passwords for nearly 4 years (in my case)?
