There have been enough data breaches at this point that I'm sure all my info has been exposed multiple times (addresses, SSN, telephone number, email, etc). My email is in over a dozen breaches listed on the been pwned site. I've gotten legal letters about breaches from colleges I applied to, job boards I used, and other places that definitely have a good amount of my past personal information. And that's not even co…

freeze your credit at the three major companaies.

You can download the entire dataset using curl (will be 40+ GB) curl -s --retry 10 --retry-all-errors --remote-name-all --parallel --parallel-max 150 "https://api.pwnedpasswords.com/range/{0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F}{0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F}{0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F}{0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F}{0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F}"

It's not that I couldn't have written that oneliner, it's that I assumed you'd get blocked very quickly.

Post should've been titled "1.3 billion passwords were exposed", because, even though the number is slightly smaller, it actually represents something much more important.

The number of passwords is probably smaller. ;)

~1.3e9 passwords, ~1.9e9 (account, password) tuples, if I understood

Now that I'm not only using a Macbook and iPhone, I've been looking for cross-platform solutions. For a week I've been using KeePassXC + Syncthing between four devices. Syncthing is also syncing my Obsidian vaults which has replaced Apple-only Notes.app. Bitwarden is definitely more polished, and Syncthing is definitely (much) more fiddly than using Bitwarden's and Obsidian's ($5/mo) native syncing tools. But I like…

Why not just run a vaultwarden instance at that point?

No matter how you sync, a Keepass file is a file. I can't be logged out. It will still be on my phone if my house burns down. Every device it's synced to is an additional backup copy.

The Bitwarden client will sometimes log you out if something happens on the server side, which has the potential to make worst case recovery from annoying to impossible. The circular dependency of having my cloud backup password in the vault made me nervous.

Yes, you can back your vault up, but it's a manual step and likely to be forgotten.

+1 for Bitwarden. It is literally the best solution out there. Been getting to increase uptake in personal circles with (very) limited success. The wife keeps trying to convince me that the ship has sailed in trying to protect info online. She's probably right.

You can throw a keepass vault on OneDrive or Dropbox and it works just fine everywhere. Not fiddly at all except Linux and OneDrive support.

> we run on Azure SQL Hyperscale, which we maxed out at 80 cores for almost two weeks the data challenge is interesting here. there's clearly a lot of data - but really its just emails and passwords you need to keep track of. SQL feels like overkill that will be too slow and cost you too much. are there better solutions? 15 billion records of email+password, assume ~40bytes thats roughly 600GB should be searchable wi…

> I'm not clear why any solution to insert new records would take 2 weeks...

The article mentions some of the challenges, like 1.9e9 sha1 hashes. And 1.9e9 row updates performing poorly in-place, so they created a separate table for the results. Then they got rate limited by email providers when they wanted to tell people about their pwnage

I respect Troy Hunt's work. I searched for my email address on https://haveibeenpwned.com/ , and my email was in the latest breach data set. But the site does not give me any way to take action. haveibeenpwned knows what passwords were breached, the people who breached the data knows what passwords were breached, but there does not seem to be any way for _me_, the person affected, to know what password were breached.…

> there does not seem to be any way for _me_, the person affected, to know what password were breached You should be using a unique randomly-generated password for each website. That way, one breach doesn't lead to multiple accounts getting hijacked AND you'll know which passwords were breached solely based on the website list. The only passwords I still keep in my head are: 1. The password to my password manager 2.…

Also if possible, use a unique email address for each site. I know that's not feasible for most people, and some sites (e.g. LinkedIn) are structured so that email addresses become linked, but it does provide useful isolation.

This seems to include details from a Spotify data breach in or before early 2020 that, to my knowledge, was never reported on. They did have other, similar issues that year. Reporting from the time seems to all be about one or multiple leaks/attacks involving: - Credential stuffing with data from other breaches - A leak of data (including email addresses) to "certain business partners" between April 9, 2020 and Novem…

You'd think spotify as a mature company would have had obligations to report this stuff!

I used per-account email with alias services and password managers. Also started migrating old accounts in free time. Now its pretty easy to tell the source of leak by email addresses as well as sources of spam. --- Per-account alias might sound much, but using sieve filtering [1] is amazing, and you can get a comprehensive filtering solution going with 'envelope to' (the actual address receiving the email) + 'header…

I just use +@gmail.com At the end of day day it’s all delivered to myname@gmail.com mailbox, but I can use filters based on part after “+”.
