A HACKER's goal is to gain ACCESS to a system or network and then modify it in some way. This can be done by exploiting security vulnerabilities or using malicious software such as viruses or worms. The two crossword solutions for the term 'HACKER's goal' are 'ACCESS' and 'PAR'. ACCESS refers to gaining ACCESS to a system or network, while PAR stands for 'privilege escalation attack', which is a type of attack that allows a HACKER to gain higher privileges than they normally would have.
