Yesterday we mentioned for the leak of 167 million accounts and passwords accessof LinkedIn on the Dark Web.
Leaked passwords were hashed with the SHA1 algorithm, a powerful data encryption algorithm, but if someone has enough time and resources can be broken.
We should mention that at the time of the hack (2012) LinkedIn was not salted (that is, salted with additional encryption) codeaccess, which means there were no random bits in the encrypted data to make it harder to crack.
LeakedSource, a website that publishes leaks from data breaches, appears to have already broken most of these passwords. So he published Top 49 most used social network passwords.
We should remind, that in 2012, the social network had asked all users to change their passwords, but publicly acknowledged that "only" 6,5 million accounts had been affected.
