A computer hacker is a computer expert who uses their technical knowledge to achieve a goal or overcome an obstacle, within a computerized system by non-standard means. Though the term hacker has become associated in popular culture with a security hacker – someone who utilizes their technical know-how of bugs or exploits to break into computer systems and access data which would otherwise be unavailable to them – hacking can also be utilized by legitimate figures in legal situations. For example, law enforcement agencies sometimes use hacking techniques in order to collect evidence on criminals and other malicious actors. This could include using anonymity tools to mask their identities online, posing as criminals themselves. Likewise, covert world agencies can employ hacking techniques in the legal conduct of their work. Oppositely, hacking and cyber-attacks are used extra- and illegally by law enforcement and security agencies, and employed by State actors as a weapon of both legal and illegal warfare.
A script kiddie, skiddie, or skid is a relatively unskilled individual who uses scripts or programs, such as a web shell, developed by others to attack computer systems and networks and deface websites, according to the programming and hacking cultures.

However, the term does not relate to the actual age of the participant. The term is considered to be derogatory.

SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution. SQL injection must exploit a security vulnerability in an application's software, for example, when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and unexpectedly executed. SQL injection is mostly known as an attack vector for websites but can be used to attack any type of SQL database.
