What term describes someone who manipulates telecommunications systems to make free calls?

• A. Cracker
• B. Phisher
• C. Phreaker
• D. Script Kiddie

Answer: (C)

Phreaking is the term for someone who manipulates telecommunications systems to make free calls. Historically, phreakers exploited the signaling tones and switching mechanisms of phone networks to route calls without paying, using devices that mimicked legitimate system signals. This focus on defeating the telephone network itself sets it apart from other hacker labels: a cracker targets computer systems for unauthorized access or damage, a phisher uses social engineering to steal information or money, and a script kiddie relies on pre-made tools with little understanding. In this context, the essence is manipulating the telecom signaling to bypass billing, which is precisely what a phreaker does.
