![]() ![]() As it turns out, they’re also great at calculating hashes too. GPU stands for graphical processing unit – they were built to make pictures load faster on your computer screen (and to play great video games). A GPU is the shiny square tile on your graphics card that says NVIDIA or AMD on it. Among other things, this special circuit board has a GPU on it. Graphics cards are those circuit boards that stick out of your computer’s bigger green circuit board. You can do that with any computer, but it is much faster if you accelerate the process with a powerful graphics card. Then you look for matches between the list and a breached database of password hashes. In this context, “ cracking” means making a list of all combinations of characters on your keyboard and then hashing them. The way that hackers solve this problem is by “cracking” the passwords instead. Hashing software is a one-way-street by design. A hash digest like 5f4dcc3b5aa765d61d8327deb882cf99 can’t be computed to produce the word “password” that was used to make it. Passwords are stored in servers as hashes like this instead of in plain text like “password.” That way, if someone steals the database all they can see are these hashes but not the password that made them. Now if you hash the word “password” using MD5 hashing software, you’ll also get 5f4dcc3b5aa765d61d8327deb882cf99! You and your friend both secretly know the word “password” is the secret code, but anyone else watching you just sees 5f4dcc3b5aa765d61d8327deb882cf99. In other words, if your friend hashes the word “password” using MD5 hashing software, the output hash will be 5f4dcc3b5aa765d61d8327deb882cf99. We’re going to talk about “hashing.” In the context of passwords, a “hash” is a scrambled version of text that is reproducible if you know what hash software was used. This only impacts the right-most column of the password table.įirst, let’s get some key terms out of the way. Most websites only accept these and so we dropped the rest. This year we’ve updated our cracking hardware to the latest and greatest, including that of the internet darling ChatGPT! We also opted for a more realistic set of special characters in our testing. We looked at big name providers like Amazon AWS and Microsoft Azure but also the growing non-corporate options where you can rent a person’s computer at cost per hour. The data was based on how long it would take a consumer-budget hacker to crack your password hash using a desktop computer with a top-tier graphics card and then how long an organized-crime-budget hacker would take leveraging cloud compute resources. In 2022, we shared our update to a colorful infographic table that showed the relative strength of a hashed password against a cracking attempt, based on the password’s length, complexity, hashing algorithm used by the victim, and the hardware used by the attacker. Got a question or comment? Leave it below or message us on your favorite social media platform. So we’ll talk through the data, our assumptions, and oh, you’re going to see a LOT of variations of the password table. While the data fits nicely into the table above, things aren’t as as simple as they look. But for those of you that want to know about the “how” then you’ve come to the right place because we’re going to walk you through our methodology. Person: Was it trombone? No, Troubador.Since 2020, we’ve conducted a lot of research to develop and present the Hive Systems Password Table. Yes, cracking a stolen hash is faster, but it's not what the average user should worry about.) (Plausible attack on a weak remote web service. (You can add a few more bits to account for the fact that this is only one of a few common formats.) Uncommon (non-gibberish) base word ]Ĭaps? ]Ĭommon Substitutions ] On each row, the first panel explains the breakdown of a password, the second panel shows how long it would take for a computer to guess, and the third panel provides an example scene showing someone trying to remember the password.)) The comic is laid out with 6 panels arranged in a 3x2 grid. A set of boxes is used to indicate how many bits of entropy a section of the password provides. ((The comic illustrates the relative strength of passwords assuming basic knowledge of the system used to generate them. ![]()
