That's quite possible, for sure. I am not beyond/above/below being phished like anyone else, ha!

The issue -- what makes it perplexing -- is that I haven't used this LastPass password since 2017. I know because this LastPass account was only used to share passwords within an org that I left back then.

Is it possible that I was phished 4 years ago, and they sat on the password? Sure.

But 2 other people in this thread being phished from the same exact same phishing server/group?

Or we were separately phished using different techniques, and now one Brazil server attempted to use all of our logins?

That's what's rather strange.

That doesn't mean they didn't try stuffing it elsewhere previously, or have login attempts you weren't notified of.

Nor do you know if the entity responsible for the failed login is the one who originally captured the credentials.

If you'll forgive the wild speculation, your credentials could have been sold recently and the new owners are less picky about alerting victims to the breach.

It could be that a bunch of credentials were captured for a specific purpose. Perhaps it was a targetted attack aiming for a specific victim, you and others here were collateral damage, and now the attacker is selling the assets.

I also generally am more suspicious of the idea that they sat on the credentials for years. Although that is not impossible.

One disproving fact (of sitting on the password for years) is that a few people here in this thread confirm having a login attempt from the exact same ip range, but with an account that was created this year -- in one case, in November 2021:

So... it might turn out to be a much more recent vulnerability after all.

I'm still seeing hackers trying to log on using passwords I haven't used in ~10 years, because it's on a list somewhere.

So LastPass (their extension) may have been hacked ~5 years ago ish, a few people here on the thread were all hacked in the same way, our passwords were sold off, and now the same Brazil IP range just tried all of those passwords.

That would make "more sense" that our credentials weren't stored and unused for years, i.e. that this is possibly a new, recent breach.

How many extensions are you using again? :-)

“Too many” :)

EditThisCookie was last updated November 22, 2020, so it doesn't seem likely from that.

ublock origin was updated December 2, 2021, but they haven't changed devs or anything that would make me suspicious.

I agree that it could be totally unrelated to the root mystery though. But "everyone here fell for malware or got phished" seems like the most likely explanation, even if my answer happens to be otherwise incorrect.
