![]() Today we somehow have got a bit of control over them with the use of CAPTCHA or Rate Limiting but still, they are one of the effective attacks. No matter how simple cracking passwords or performing Credential Stuffing were once a bane on the Web Applications. Table of ContentsĮver since the evolution of Penetration Testers has begun, one of the things we constantly see is that the attacker cracks the password of the target and gets in! Well in most of the depictions of the attacks in movies and series often show this situation in detail as it is the simplest attack to depict. Today we are going to understand wordlists, look around for some good wordlists, run some tools to manage the wordlists, and much more. You shouldn't be using any of these for any of your accounts.A Pentester is as good as their tools and when it comes to cracking the password, stressing authentication panels or even a simple directory Bruteforce it all drills down to the wordlists that you use. Here are the 100 most commonly passwords, according to Hakçıl's analysis. To create and remember such passwords, and to make sure none of them is repeated, there's no better solution that to use one of the best password managers. Length is currently the most important factor, as a 20-character password of random lowercase letters has less chance of being "cracked" than a 12-character password made up of lowercase and uppercase letters, digits and punctuation marks and other special characters.īut ideally, you'd want a long password of at least 15 characters made of absolute gibberish containing all four types of characters found on a common QWERTY computer keyboard. To make sure to limit the extent of a data breach upon your account security, make sure that all of your passwords are long, strong and unique. Hakçıl started with about 1 billion pairs of credentials (passwords and usernames), but had to toss out more than 257 million pairs for being either unreadable or obviously test accounts. "All the ideas about this are welcome and appreciated." "I have no idea what this uncovers and what it implies, but I'm suspecting a password manager out there is creating passwords with low entropy, causing repetitions over a lot of users," Hakçıl wrote. "None of them seem to have a keyboard pattern or meaningful word in them" and "they don't contain special characters."Įven though the passwords appeared to be machine-generated, several of them appeared to have been reused, possibly indicating a flaw in a password-generation algorithm. "They all start and end with uppercase characters," Hakçıl wrote. Hakçıl did find one surprising thing - some 763,000 10-character passwords of gibberish that nevertheless followed a predictable pattern. "qwerty123" - but only 4.5% started with the numbers. In an indication of how people form passwords, more that 34% of passwords that mixed letters and numbers ended with the numbers - e.g. Including such characters goes a long way to beefing up a password's strength against password crackers.īy contrast, nearly 29% of the passwords were compromised of letters only, and more than 26% of the total were lowercase only. Only 12% of the passwords Hakçıl examined contained "special" characters, such as punctuation marks, that are found on common QWERTY keyboards but are not letters or numbers: ? & ^ and so on. (We're not sure why that occurred, but RockYou may have required the inclusion of upper-case letters at some point.) Two others came close but not quite, with "Password" and "Qwerty" appearing in the RockYou Top 20, but "password" and "qwerty" in Hakçıl's Top 20. The RockYou database's most-used password is also "123456." In fact, of the top 20 old RockYou passwords, entered between 20, seven are also in Hakçıl's brand-new Top 20 list: 123456, 12345, 123456789, iloveyou, 1234567, 12345678 and abc123. Same old songīut that's still far outweighed by the bad news. UPDATE: We played with the RockYou statistics in this report from Imperva and came up with an average RockYou password length of roughly 7.41 characters.
