1 Billion Password List Download

[Geri Cutcher]

Ipresent you a new rockyou2024 password list with over 9.9 billion passwords! I updated rockyou21 with collected new data from recent leaked databases in various forums over this and last years. Also cracked some old ones with my new 4090. This contains actual new real passwords from users.

Also, the MOAB contained more than just usernames and passwords: it included other information associated with the breached accounts. That could include medical records and other sensitive information.

As a penetration tester, I have to keep up with these sorts of breaches, both for personal development and simply to stay up to date in the field to carry out my job well. The cyber landscape is a fast-changing one; you need to stay on top of the latest news, threats and vulnerabilities.

On a popular hacking form, a user has leaked a file that contains 9,948,575,739 unique plaintext passwords. The list appears to be a compilation of passwords that were obtained during several old and more recent data breaches.

Another possible use for cybercriminals is to combine the list with data from other breaches, such as combinations of usernames and passwords, which could get results if the password has been reused. If the cybercriminals also have a list that contains hashed passwords, they could even try to match the hash values of the passwords.

Pwned Passwords are hundreds of millions of real world passwords previously exposed in data breaches.This exposure makes them unsuitable for ongoing use as they're at much greater risk of beingused to take over other accounts. They're searchable online below as well as beingdownloadable for use in other online systems. Read more about how HIBP protects the privacy of searched passwords.

This password wasn't found in any of the Pwned Passwords loaded into Have I Been Pwned.That doesn't necessarily mean it's a good password, merely that it's not indexedon this site. If you're not already using a password manager, go and download 1Passwordand change all your passwords to be strong and unique.

Password reuse is normal. It's extremely risky, but it's so common because it's easy andpeople aren't aware of the potential impact. Attacks such as credential stuffingtake advantage of reused credentials by automating login attempts against systems using knownemails and password pairs.

The Pwned Passwords service was created in August 2017 after NIST released guidance specifically recommending that user-provided passwords be checkedagainst existing data breaches. The rationale for this advice and suggestions for howapplications may leverage this data is described in detail in the blog post titledIntroducing 306 Million Freely Downloadable Pwned Passwords.In February 2018, version 2 of the service was releasedwith more than half a billion passwords, each now also with a count of how many times they'dbeen seen exposed. A version 3 release in July 2018contributed a further 16M passwords, version 4 came in January 2019along with the "Collection #1" data breach to bring the total to over 551M.Version 5 landed in July 2019with a total count of 555M records, version 6 arrived June 2020with almost 573M then version 7 arrived November 2020bringing the total passwords to over 613M. The final monolithic release was version 8 in December 2021which marked the beginning of the ingestion pipeline utilised by law enforcement agencies such as the FBI.

As of May 2022, the best way to get the most up to date passwords is to use the Pwned Passwords downloader.The downloaded password hashes may be integrated into other systems and used to verifywhether a password has previously appeared in a data breach after which a system may warn theuser or even block the password outright. For suggestions on integration practices,read the Pwned Passwords launch blog postfor more information.

The costs of providing this service for free would be extensive were it not forCloudflare's support. They providethe resources to ensure more than 99% of all queries are served directly from theirinfrastructure by aggressively caching the data at their edge nodes over and beyond whatwould normally be freely available. Their support in making this data available to helporganisations protect their customers is most appreciated.

In case it doesn't show up, check your junk mail and ifyou still can't find it, you can always repeat this process.

A brute force attack is a popular hacking method where the attacker guesses a user's password by trial-and-error. Hackers commonly use automated scripts when carrying out a brute force attack, which enables them to try out a slew of passwords within a short period of time. With a leaked password database this big, hackers have a nearly unlimited pool of passwords to try out.

In its essence, the RockYou2024 leak is a compilation of real-world passwords used by individuals all over the world," writes Cybernews' researchers. "Revealing that many passwords for threat actors substantially heightens the risk of credential stuffing attacks."

In fact, the hacker forum user "ObamaCare" claims they used that older list and updated it with newer password leak data from over the past three years. As a result, 1.5 billion more passwords have been added to the previous compilation to create RockYou2024.

"I updated rockyou21 with collected new data from recent leaked databases in various forums over this and last years," wrote the hacker forum user while adding that they also included recent compromised passwords that they recently obtained themself.

Anyone signed up to any service online should assume that a password that they use is on this list. Cybersecurity researchers recommend that users update their passwords and enable multi-factor authentication wherever possible.

Many of the so-called RockYou2024 passwords have already been leaked in previous data breaches. This is not the first RockYou data dump either, as the name has been associated with a number of large-scale password leaks since 2009.

Jake Moore, global cybersecurity advisor at security firm ESET, told TechRepublic: User credentials are constantly being caught up in data breaches and they end up being collected and stored in large databases on the dark web.

Security researchers from Cybernews say they have uncovered what appears to be the biggest collection of stolen and leaked credentials ever seen on the BreachForums criminal underground forum. Containing what is said to be an astonishing 9,948,575,739 unique passwords, all in plaintext format, the RockYou2024 compilation apparently comprises an earlier credentials database known as RockYou 2021, which featured 8.4 billion passwords, adding approximately 1.5 billion new passwords into the mix. These cover the period from 2021 through 2024, and it has been estimated that the latest credentials file contains entries from a total of 4,000 huge databases of stolen credentials covering at least two decades.

Last August, I launched a little feature within Have I Been Pwned (HIBP) I called Pwned Passwords. This was a list of 320 million passwords from a range of different data breaches which organisations could use to better protect their own systems. How? NIST explains:

When processing requests to establish and change memorized secrets, verifiers SHALL compare the prospective secrets against a list that contains values known to be commonly-used, expected, or compromised.

They then go on to recommend that passwords "obtained from previous breach corpuses" should be disallowed and that the service should "advise the subscriber that they need to select a different secret". This makes a lot of sense when you think about it: if someone is signing up to a service with a password that has previously appeared in a data breach, either it's the same person reusing their passwords (bad) or two different people who through mere coincidence, have chosen exactly the same password. In reality, this means they probably both have dogs with the same name or some other personal attribute they're naming their passwords after (also bad).

Now all of this was great advice from NIST, but they stopped short of providing the one thing organisations really need to make all this work: the passwords themselves. That's why I created Pwned Passwords - because there was a gap that needed filling - and let's face it, I do have access to rather a lot of them courtesy of running HIBP. So 6 months ago I launched the service and today, I'm pleased to launch version 2 with more passwords, more features and something I'm particularly excited about - more privacy. Here's what it's all about:

Back at the V1 launch, I explained how the original data set was comprised of sources such as the Anti Public and Exploit.in combo lists as well as "a variety of other data sources". In V2, I've expanded that to include a bunch of data sources along with 2 major ones:

There's also a heap of other separate sources there where passwords were available in plain text. As with V1, I'm not going to name them here, suffice to say it's a broad collection from many more breaches than I used in the original version. It's taken a heap of effort to parse through these but it's helped build that list up to beyond the half billion mark which is a significant amount of data. From a defensive standpoint, this is good - more data means more ability to block risky passwords.

It doesn't matter that SHA1 is a fast algorithm unsuitable for storing your customers' passwords with because that's not what we're doing here, it's simply about ensuring the source passwords are not immediately visible.

That's still 100% true as of today. There are certainly those that don't agree with this approach; they claim that either the data is easily discoverable enough online anyway or conversely, that SHA-1 is an insufficiently robust algorithm for password storage. They're right, too - on both points - but that's not what this is about. The entire point is to ensure that any personal info in the source data is obfuscated such that it requires a concerted effort to remove the protection, but that the data is still usable for its intended purposes. SHA-1 has done that in V1 and I'm still confident enough in the model to use the same approach in V2.
