Password Change

Your Password is Already In the Wild, You Did not Know?

There was a lot of buzz about the leak of two huge databases of passwords a few days ago. This has been reported by Try Hunt on his blog. The two databases are called “Anti-Trust-Combo-List” and “Exploit.In“. If the sources of the leaks are not officially known, there are some ways to discover some of them (see my previous article about the “+” feature offered by Google).

A few days after the first leak, a second version of “Exploit.In” was released with even more passwords:

Name

Size

Credentials

Anti-Trust-Combo-List

16GB

540.701.509

Exploit.In

15GB

499.305.318

Exploit.In (2)

24GB

805.499.579

With the huge of amount of passwords released in the wild, you can assume that your password is also included. But what are those passwords? I used Robbin Wood‘s tool pipal to analyze those passwords.

I decided to analyze the Anti-Trust-Combo-List but I had to restart several times due to a lack of resources (pipal requires a lot of memory to generate the statistics) and it failed always. I decided to use a sample of the passwords. I successfully analyzed 91M passwords. The results generated by pipal are available below.

What can we deduce? Weak passwords remain classic. Most passwords have only 8 characters and are based on lowercase characters. Interesting fact: users like to “increase” the complexity of the password by adding trailing numbers:

  • Just one number (due to the fact that they have to change it regularly and just increase it at every expiration)
  • By adding their birth year
  • By adding the current year
