In a breach scenario, which term describes the attack on a PBX system used to store music files?

• A. Pretexting
• B. Squatting
• C. Phreaking
• D. Crunching

Answer: (C)

Phreaking is about manipulating telephone networks and switching equipment, such as a PBX, to gain unauthorized access or control. In a breach involving a PBX that stores music files, the attacker is exploiting the telephony infrastructure to reach or tamper with the files hosted on the PBX, or to alter how the system operates. This aligns with phreaking, which covers exploiting telecom systems to access resources or bypass controls. Pretexting is about social engineering to obtain information by posing as someone else, not about tampering with the telecom hardware. Crunching refers to breaking codes or performing heavy data processing, not specifically telecom intrusion. Squatting isn’t a standard term for PBX attacks and doesn’t describe this telco-focused breach.
