The Kryc Wordlist ---[ 1. What is it? The kryc wordlist is a list of commonly used passwords for use in security research (particularly user education and password recovery) and Capture the Flag (CTF) competitions. ---[ 2. How is it created? The wordlist comes in at just under 500 million passwords and is based on the haveibeenpwned pwned passwords list. haveibeenpwned releases sha1 hashes of passwords recovered from known security breaches. For more information on how they build this list see https://haveibeenpwned.com. At time of writing 98.71% of the passwords have been recovered to their plaintext (I may write a full article on this if there is interest). The kryc wordlist is a sorted list of passwords which have appeared in at least ten different breaches (to filter out the long tail of passwords which have only been seen once). It is then filtered to remove any non-UTF-8-printable entries, and any that are likely to be email addresses. Finally it is compressed using LZMA2 into an .xz archive. ---[ 3. What is in it? In case you are interested, the top ten entries are 1. 123456 6. 1234 2. 123456789 7. 12345 3. 12345678 8. qwerty 4. password 9. 1234567 5. admin 10. 1234567890 ---[ 4.
