Crackers unlike hackers, hack into computer systems in order to steal, corrupt, or illegitimately view data.

Crackers are people who illegally access information on the internet which they usually would not have access to. Although almost all forms of hacking are highly illegal, there is often a distinction made between hackers who perform such actions for what they view as good causes (such as testing security systems or combatting cyber-terrorism, known as "White Hat hackers") and crackers, those who use it for personal gain (such as stealing accounts, identity theft or in extreme cases trying to gain information on governments/military, also known as "Black Hat hackers"). Some does unethical cracking/hacking but not for personal gains, which they will disclose such vulnerabilities to the organization (known as "Gray Hat hackers").
