Hackers build, while crackers break. That would be the basic difference between hacking and cracking in relation to computer security. But the further question would be: What is built and what is broken into?
A cracker is someone who breaks into a network; bypasses passwords or licenses in computer programs; or in other ways intentionally breaches computer security. Crackers also act as Black Hats: by gaining access to the accounts of people maliciously and misusing this information across networks. They can steal credit card information, they can destroy important files, disclose crucial data and information or personal details and sell them for personal gains.
The basic difference is that a hacker uses their extensive knowledge of computer logic and code, while a cracker looks for back doors in programs, and exploits those back doors. Hackers break into the security systems for the sole purpose of checking the holes in the system and works on rectifying these while as the Cracker breaks into the security system for criminal and illegal reasons or for personal gains. 2b1af7f3a8
