RockYou Hack Reveals the Worst 20 Passwords
-
The article doesn't actually say that they don't. Given the passwords, the list could have been constructed by a bot hacking accounts with a bot using a dictionary attack, but I suspect your assumption that they just stored the passwords either clear text or with reversible encryption is correct. 5 for the observation, which I heartily agree with.

from the article: By far, the most popular password on the site was "123456," apparently satisfying a minimum character limit on the site's password restrictions, but doing little for security. A full 290,731 users used this password, far more than the runner-up, the slightly less complex "12345, which attracted 79,078 uses. clickty[^] I have learned a simple trick to create mid-to-strong password by simple substitution. Let us take "codeproject" as case example, it goes as follows - first let us capitalize some letters => CodeProject - substitute "o" with "0" => C0deProject - upper case e (E) can be imagined as mirror image of 3 => C0d3Pr0j3ct - let us sprinkle some chars (SHIFT 3 = # on the US layout keyboard) => C0d#Pr0j#ct - Finally P can be imagines as mirror image of 9 => C0d#9r0j#ct So we went from codeproject => C0d#9r0j#ct and I can use Code Project as my password hint. :cool: The cool part is there is no limit to the imagination and the resulting password can be as close as random characters. How do you create your password?

Just how important is a very secure password when the site you are using gets hacked and exposes your PW in plain-text?

Take a poem, song lyric, quote, etc, and use the first letter from each word. You can get 20-30 characters easy. That other stuff is just too hard to remember.

I have the free version but the generated passwords are hard to remember. By the way who am I :confused:

Well said.

I've read a few more articles about the breach. Plaintext passwords in the DB and a simple SQL injection attack were involved.
3x12=36 2x12=24 1x12=12 0x12=18
Oooo! I love the smell of professionalism in the morning!

Haven't read the article (because it took so long to load that I got bored and went away), but to be honest any site which stores a password in any form other than one-way encrypted or SHA hashed is not one I realy want to visit.

even if they are hashed, you can find out who uses "123456" by generating the hash for "123456" and finding the matches in your list of hashed pwds.

Don't forget to include a couple of :-) in you pwd. (or :-( for your online banking).

Passwords are just a giant PITA tho. It bugs me that just about any site or organisation I go to that requests I use a password, all have a completely different policy on how the password is composed, some accept all alphanumeric characters, some don't, some specify a number at the start of the string, others at the end, it leads me to having a multitude of passwords, that, more often than not, I have to go through the rigmarole of resetting a password everytime I visit a site, because I cant remember the exact sequence of characters for that specific sites password. Now surely that is defeating the object of having a password in the first place. With that in mind, you can see why some people just use strings like "123456" as at least it is easy to remember. I wish someone would invent another way to protect access to your stuff on line.....

> even if they are hashed, you can find out who uses "123456" by generating the hash for "123456" and finding the matches in your list of hashed pwds. What you do is include a "salt" value when you create the hash. This is a known random value, stored with the hash. You apply it with the password when creating the hash to see if it matches, but is really difficult to apply in the reverse direction. So a simple dictionary-style comparison won't work.

That is why you use the user name and a private string to salt the hash, so no two users with the same password will have the same hashed password. Because of the private string you can not even generate a hash and inject that into the database.

yes, i know what a salt is. but, even if a salt value was used, it's sitting right there in the DB along with the hash. and you already know the target password, so the problem of finding who used that password remains trivial.

Ah, you mean in terms of auditing "weak" passwords, and not in terms of trying to hack into a system...
