Have I been Pwned? (HIBP)​

Go to Have I Been Pwned

I'm Troy Hunt, a Microsoft Regional Director and Most Valuable Professional awardee for Developer Security, blogger at troyhunt.com, international speaker on web security and the author of many top-rating security courses for web developers on Pluralsight.

I created Have I been pwned? as a free resource for anyone to quickly assess if they may have been put at risk due to an online account of theirs having been compromised or "pwned" in a data breach. I wanted to keep it dead simple to use and entirely free so that it could be of maximum benefit to the community.

This service is actually pretty great, I've used it and have been notified twice now, one being just yesterday for the tumblr hack. There's not harm just setting up this update to have the bot look out for your email addresses in case any of them turn up in data dumps from breaches.

Very good service and indeed accurate, my two primary emails are indeed pwned because I've created account on Tumblr and Malwarebytes before.

However that does not decrease my self-esteem in the security. ;) Cause until now mistakes from webmasters happened often in such rare situation.

Useful service. One of my emails from 8 years ago did get pwned on VK, the russian social media site. I'm not even russian and don't know why I signed up there. o_O

source (bleepingcomputer.com): New Tools Make Checking for Leaked Passwords a Lot Easier

The work that Australian security researcher Troy Hunt has done with the Have I Been Pwned project is yielding useful tools that developers and webmasters can now use to make sure users stop using silly and easy to guess passwords.

Hunt has been collecting data exposed in data breaches for some time now. His Have I Been Pwned (HIBP) portal has been allowing users to safely check if their name, emails, or other details were included in a public data breach.

Pwned Passwords v2 launches
Hunt has recently revamped the Pwned Password service —announcing v2 a week ago— and now includes 501,636,842 compromised passwords. Just like in v1, this data is available via the Pwned Passwords online site, via an API, and as a downloadable archive, in case developers want to build locally-stored apps and services.

Yesterday, Hunt announced that his project got an official seal of approval from government entities. Hunt said he's in the process of assisting IT staffers from the UK and Australian governments with implementing the Pwned Passwords service for official government domains, so government employees can't use simple or leaked passwords to secure their accounts.

Below is a (probably incomplete) list of projects that have implemented the Pwned Passwords service. These tools can be used by both end users, but also other developers who want to add checks for compromised passwords in their apps or services. We hope that slowly but surely, apps and websites that check for weak or leaked passwords will become the norm, just like the recent NIST password guidelines require.

christophetd/firepwned - Checks Firefox saved passwords against known data leaks using the HIBP PP API
moviuro/pass-hibp - A Linux pass(1) extension that queries the HIBP PP API
kevlar1818/is_my_password_pwned - Bash script for HIBP PP API
sea-erkin/goPasswordCheck - Go library for the HIBP PP API
JoshHarmon/kAnonymity-Password-Checking-MyBB - MyBB plugin integrating the HIBP PP API
alzeih/pass-pwned - Linux Password-Store extension for the HIBP PP API
RawInfoSec/hibp-chk - A PHP function for implementing password checks the HIBP PP API
RandomAdversary/PwnedPasswords - Java library for the HIBP PP API
nistykcab/unpwnedpsswd-gen - Python script to generate unique passwords that have not yet been recorded in Pwned Passwords

a person finds out their online profile/email was hacked with this service. What is the next step beyond changing the password assuming that this was the reason for the leak? Contacting the breached company?

My main email got breached multiple times on haveibeenpwned site, and the only two things I can do are change password and enable 2 factors auth. Other than that, I have to make a new email. My email also contain fake info so I don't think DeepWeb criminals can do any damage on me.

These information are fundamental for all users. Latest big cyberattacks were aiming to steal credentials and accounts. Collection #1 attack contained not only email accounts but also social networks accounts, e-commerce accounts, banking credentials, etc. I recommend to use HaveIBeenPwned very often to check emails used for accounts, then use complex passwords (better long) with numbers, uppercase, lowercase characters and special characters (like &, %, #, *) and don't use the same password for more sites. Stolen data and credentials are sold in the dark web. Most popular online services nowadays offer 2 step verification login method, enable it to be more secure.
