Default Check where your email address was breached

This is fun: enter your email address(es) and see which of the many public data breaches it's in. (I'm looking at you, lisapea.)

Have I been pwned? Check if your email has been compromised in a data breach :freakout:

Despite the spammy-sounding site name and the hackerish logo ';-- ... (a classic SQL injection trick - see Bobby Tables) and the very idea of entering your email addresses on a site because it suggested you do, it seems legit. Have I Been Pwned? - Wikipedia - Is "Have I Been Pwned's" Pwned Passwords List really that useful? - Information Security Stack Exchange

Chances are if you've had a LinkedIn account or a Dropbox account for more than a few years, that email address will be in there (and you will have responsibly changed your password when those providers warned you about their breaches).

One of my email addresses appears in a Neopets breach ... that's obviously going back some time ... when Little Miss JoeP was playing it.

I also realise that I have a lot of email addresses, some of them old work addresses that are no longer active. But lots still active. And the important ones have not been pwned! :D

Default Re: Check where your email address was breached

And if that's not enough for you, enter your password at Have I been pwned? Pwned Passwords and see how unique it is.

'Password1' appears 102,031 times
'P@ssword1' appears 2,580 times
'lisarea' appears 6 times :eek:
'JoeP' doesn't appear at all! :D

If you really want to check a number of passwords and you don't like the idea of entering them over an https link to a possibly trustworthy site, because who knows, you can download the entire 9GB file and check on your own machine. It contains SHA1 hashes not the original passwords because that's just sensible.

Ha ha, I knew about that site already. Both Matlock and I have been multiply pwned, but because we both have early, sought-after Gmail addresses (and I have more than one), only a couple were actually us.

I also mostly use masked emails these days, but I have like one billion of them, all with unique passwords, so I'm not going to even bother checking them.

Default Re: Check where your email address was breached

2 out of 3, but was forced changed passwords as a result of one, and the other breaches were very old (password since changed) or concerned sites that would've had outdated info...

Probably should change all my passwords anyway though...

I wasn't fishing for the number of email addresses y'all have, but that's an interesting side benefit.

I have several more than erimir and Ding (3) but a few less than pea ("one billion" :drevil:).

Yahoo (since 1994), Google (since 2003), and Hotmail (2002?). I also have a CoxCommunications.com email, but haven't ever used it. I used to have AOL and Prodigy email addies, but whatever.

If you don't want to enter your password and don't want to download gigabytes of data either, you can send the first 5 characters of the SHA-1 hash (or the complete hash) of your password and you get a list of suffixes back like this:

Guess what the entry with 3 million hits is? That's right, "password".

It's probably a good idea to test the procedure with a very common password; I just found out that Emacs adds final newlines to text files that don't have any, which gives the wrong hash.
