That's really so strange. What is the probability that you, techknight (the other user in this thread) and me used the exact same compromised software back in ~2017 and had our master passwords stolen then? And for that person/bot (in Brazil) to try all of those master passwords now? It's beginning to look like this is a LastPass issue, no..?

it certainly does look like a lastpass issue....

LastPass was my first thought, but I couldn't find anyone else having the same issue and decided it couldn't possibly be them. Now I'm not sure! I've emailed you a list of the extensions I use in Chrome - if you want to share publicly any that we have in common I'm okay with that

  Hey, thanks -- just replied to your email. 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)?

    One other breadcrumb: https://news.ycombinator.com/item?id=29706957 https://news.ycombinator.com/item?id=29706957 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?
        gregsadetsky 5y ago
        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.
