We have discussed alot about popular password cracking methods such as Bruteforce, Dictionary attack and Rainbow tables. However a question I get asked frequently is if it’s possible to crack a Facebook account. So I wish to clear concepts related to Hacking/Cracking Facebook accounts. First of all “Hacking a Facebook account” and “Cracking a facebook account” are both different terminologies.
Hacking a facebook account refers to foolproof methods such as Phishing, keylogging, Social engineering etc.
However the terminology cracking refers to the methods such as Bruteforce, Dictionary attacks etc.
Brute Force Attacks
Bruteforce is one of the most common and most reliable password cracking methodologies. A bruteforce attack tries all possible combinations against the medium, until the correct password is found. However the problem with a bruteforce attack is that as the password complexity increases, the time taken to crack a password also increases.
The chart above illustrates the time the estimated time taken by a computer in order to bruteforce a password, assuming that if it’s capable of trying 10,000 passwords per second. However, the time taken can be reduced by adding the number of processors to the task. Therefore the only flaw with the attack is that it requires lots of potential.
