mkj<a href="https://infosec.exchange/@AmbianceAsunder" class="u-url mention" rel="nofollow noopener" target="_blank">@AmbianceAsunder</a> The only heuristic I recommend for passwords is *unique*, either Diceware or fully random alphanumeric.For random alphanumeric, I recommend 15 characters or longer.For 5-dice Diceware, I recommend 6 words or longer.(By rather remarkable coincidence both of those work out to the same work factor: about 2^77 if you use single-case.)Which is pretty much unmanageable without a password manager, so get one.<a href="https://twit.social/@MisuseCase" class="u-url mention" rel="nofollow noopener" target="_blank">@MisuseCase</a><a href="https://social.mkj.earth/tags/password" class="mention hashtag" rel="nofollow noopener" target="_blank">#password</a> <a href="https://social.mkj.earth/tags/passwords" class="mention hashtag" rel="nofollow noopener" target="_blank">#passwords</a> <a href="https://social.mkj.earth/tags/Diceware" class="mention hashtag" rel="nofollow noopener" target="_blank">#Diceware</a> <a href="https://social.mkj.earth/tags/passphrase" class="mention hashtag" rel="nofollow noopener" target="_blank">#passphrase</a> <a href="https://social.mkj.earth/tags/passphrases" class="mention hashtag" rel="nofollow noopener" target="_blank">#passphrases</a>

postmodernI saw <a href="https://gitlab.com/initstring/passphrase-wordlist" rel="nofollow noopener" target="_blank">this passphrase wordlist</a> project popup. Just like to remind folks that passphrase passwords (ex: correcthorsebatterystapler), even with character substitution, can be enumerated and that GPUs will eventually be able to bruteforce the inevitable password dumps from data breaches. In fact a certain someone wrote up a blog post two years ago showing how you could <a href="https://postmodern.github.io/blog/2022/01/23/enumerating-xkcd-style-passwords-with-ruby.html" rel="nofollow noopener" target="_blank">enumerate all permutations of passphrases using Ruby</a> to build your own custom passphrase wordlists; which of course was met with immediate poo-pooing upon. <a href="https://infosec.exchange/tags/wordlists" class="mention hashtag" rel="nofollow noopener" target="_blank">#wordlists</a> <a href="https://infosec.exchange/tags/passphrase" class="mention hashtag" rel="nofollow noopener" target="_blank">#passphrase</a> <a href="https://infosec.exchange/tags/enumeration" class="mention hashtag" rel="nofollow noopener" target="_blank">#enumeration</a> <a href="https://infosec.exchange/tags/ruby" class="mention hashtag" rel="nofollow noopener" target="_blank">#ruby</a>

Jeremi M Gosney :verified:Happy <a href="https://infosec.exchange/tags/WorldPasswordDay" class="mention hashtag" rel="nofollow noopener" target="_blank">#WorldPasswordDay</a>!I've cracked billions of <a href="https://infosec.exchange/tags/passwords" class="mention hashtag" rel="nofollow noopener" target="_blank">#passwords</a> from tens of thousands of <a href="https://infosec.exchange/tags/data" class="mention hashtag" rel="nofollow noopener" target="_blank">#data</a> <a href="https://infosec.exchange/tags/breaches" class="mention hashtag" rel="nofollow noopener" target="_blank">#breaches</a> in the past 12+ years, and because of this, I likely know at least one <a href="https://infosec.exchange/tags/password" class="mention hashtag" rel="nofollow noopener" target="_blank">#password</a> for 90% of people on the Internet. And I'm not alone! While I primarily crack breached passwords for research purposes and the thrill of the sport, others are selling your breached passwords to criminals who leverage them in <a href="https://infosec.exchange/tags/AccountTakeover" class="mention hashtag" rel="nofollow noopener" target="_blank">#AccountTakeover</a> and <a href="https://infosec.exchange/tags/CredentialStuffing" class="mention hashtag" rel="nofollow noopener" target="_blank">#CredentialStuffing</a> attacks. How can you keep your accounts safe?- Use a <a href="https://infosec.exchange/tags/PasswordManager" class="mention hashtag" rel="nofollow noopener" target="_blank">#PasswordManager</a>! I recommend <a href="https://fosstodon.org/@bitwarden" class="u-url mention" rel="nofollow noopener" target="_blank">@bitwarden</a> and <a href="https://1password.social/@1password" class="u-url mention" rel="nofollow noopener" target="_blank">@1password</a> - Use a <a href="https://infosec.exchange/tags/Diceware" class="mention hashtag" rel="nofollow noopener" target="_blank">#Diceware</a> style <a href="https://infosec.exchange/tags/passphrase" class="mention hashtag" rel="nofollow noopener" target="_blank">#passphrase</a> - four or more words selected at random - for passwords you have to commit to memory, like your master password!- Enable MFA for important online accounts, including cloud-based password managers!- Harden your master password by tweaking your password manager's KDF settings! For <a href="https://infosec.exchange/tags/Bitwarden" class="mention hashtag" rel="nofollow noopener" target="_blank">#Bitwarden</a>, use Argon2id with 64MB memory, 3 iterations, 4 parallelism. For <a href="https://infosec.exchange/tags/1Password" class="mention hashtag" rel="nofollow noopener" target="_blank">#1Password</a> and other PBKDF2 based password managers, set the iteration count to at least 600,000. - Use unique, randomly generated passwords for all your accounts! Use your password manager to generate random 14-16 character passwords for everything. Modern password cracking is heavily optimized for human-generated passwords, because humans are highly predictable. Randomness defeats this and forces attackers to resort to incremental brute force! There's no trick you can do to make a secure, uncrackable password on your own - your meat glob will only betray you.- Use an ad blocker like <a href="https://infosec.exchange/tags/uBlock" class="mention hashtag" rel="nofollow noopener" target="_blank">#uBlock</a> Origin to keep you safe from password-stealing <a href="https://infosec.exchange/tags/malware" class="mention hashtag" rel="nofollow noopener" target="_blank">#malware</a> and other browser based threats!- Don't fall for <a href="https://infosec.exchange/tags/phishing" class="mention hashtag" rel="nofollow noopener" target="_blank">#phishing</a> attacks and other social engineering attacks! Browser-based password managers help defend against phishing attacks because they'll never autofill your passwords on fake login pages. Think before you click, and never give your passwords to anyone, not even if they offer you chocolate or weed.- <a href="https://infosec.exchange/tags/Enterprises" class="mention hashtag" rel="nofollow noopener" target="_blank">#Enterprises</a>: require ad blockers, invest in an enterprise password management solution, audit password manager logs to ensure employes aren't sharing passwords outside the org, implement a Fine Grained Password Policy that requires a minimum of 20 characters to encourage the use of long passphrases, implement a password filter to block commonly used password patterns and compromised passwords, disable <a href="https://infosec.exchange/tags/NTLM" class="mention hashtag" rel="nofollow noopener" target="_blank">#NTLM</a> authentication and disable RC4 for <a href="https://infosec.exchange/tags/Kerberos" class="mention hashtag" rel="nofollow noopener" target="_blank">#Kerberos</a>, disable legacy broadcast protocols like LLMNR and NBT-NS, require mandatory <a href="https://infosec.exchange/tags/SMB" class="mention hashtag" rel="nofollow noopener" target="_blank">#SMB</a> signing, use Group Managed Service Accounts instead of shared passwords, monitor public data breaches for employee credentials, and crack your own passwords to audit the effectiveness of your password policy and user training!
