           | 
           | 1. There's a map feature where users can assign their
           | location to a photo that was taken. I suppose this could
           | qualify as 'physical address'.
           | 
           | 2. Businesses often have their physical addresses as part of
           | their profile.

       | I've got an Instagram burner I literally never use. Never clicked
       | weird links, never logged in anywhere sketchy, so a phishing
       | compromise makes zero sense. If my info got out, it likely came
       | from Instagram's side, not mine.
       | 
       | What's interesting is the timing pattern. I started getting
       | "reset your password" emails in early 2023, then they'd come in
       | waves. It feels like the creds were getting resold and different
       | people were taking turns running the same list. The emails were
       | in different languages too, which tracks with whoever was firing
       | off the requests.
       | 
       | Got another reset attempt a couple days ago. Congrats to the
       | latest buyer: you bought pure schwag. Whatever value was in that
       | list got milked long before it ended up public.

         | Nobody is buying your account specifically, they're buying it

         | fake/burner/bots is baked whatever the buyer is expecting. If

       | One thing I'm curious about is I hear stories about people
       | getting hacked and losing their FB/IG/Tiktok accouts then
       | fighting to get them back. You never hear details but I can only
       | assume they're reusing passwords or they're using guessable
       | passwords. For reference, anything 10 characters or less has to
       | be viewed as guessable in this day and age.
       | 
       | I've long-viewed password managers are mandatory. Every site get
       | its own 20+ character randomly generated password. I don't care
       | if the hash gets leaked. It's not getting cracked. For years this
       | has been 1Password. Initially it was LastPass but 1Password is
       | just more slick.
       | 
       | The annoyance is all the arbitrary rules sites create about you
       | have to use special characters or you can't or they have
       | different, non-overlapping requirements on password length or the
       | absolute worst is forced password rotation.
       | 
       | I don't generally try and get non-tech friends and family use
       | password managers however because it's still kinda clunky to use
       | and generate. Passkeys are kinda better I guess? But they're far
       | from universal and I don't expect them ever to be.
       | 
       | Anyway, this kind of leak from Meta kinda surprises me. Leaking
       | information that ties a physical address to an email address?
       | That's a _massive_ breach and not normally one you expect form a
       | company employing thousands of engineers.
       | 
       | I will say this: IG operates as its own domain within Meta and
       | AFAIK they still use a completely separate code base in
       | Python/Django. Facebook proper is in Hack (almost entirely) and
       | has excellent tooling and systems to detect weak endpoints and
       | PII leaks of this sort such that leaky endpoints (or however this
       | information leaked; I didn't see any details in the article)
       | really just don't happen.
       | 
       | This has long been a point of friction within Meta engineerings.
       | It's defensible to say it's not worth rewriting but IG are
       | constantly playing catch up with what the rest of the company
       | gets for "free". How many billion+ dollar settlements does it
       | take before this equation changes?
       | 
       | And yes I believe that leaking physical addresses is going to
       | cost th ecompany more than a billion dollars. It may get people
       | killed. That's how serious this is.

       | 
       | I just checked, and Instagram's password reset flow allows
       | requesting a reset using an email address, a phone number, or

       | 
       | From an attacker's perspective, this does not grant access to
       | accounts or sensitive data. It mainly causes users to receive
       | unexpected reset emails and possibly panic or change their
       | passwords. That aligns more with nuisance or malice than with a
       | meaningful breach.
       | 
       | I do not have definitive proof, but based on this behavior it
       | seems plausible that the reported wave of reset emails could be
       | explained without any large scale data leak.

         | I think there might be an effort in the "security" snake oil

         | "breach" at Twitter where it turns out it was all publicly-
         | available data users themselves put on their public profile
         | that was scraped.
         | 
         | I've personally had people argue with me that disclosing
         | whether an account was registered was a major breach and do
