Which of the following is NOT a form of telecommunications fraud?

• A. Phone phreaking
• B. Theft of telephone credit card numbers
• C. Hacking into telecommunications 'switches'
• D. Wireless phone theft and fraud

Answer: (A)

The key idea is understanding what counts as telecommunications fraud. Fraud in this realm is about illegally getting services, data, or money from the telecom system by abusing its components or processes.

The other options clearly fit that idea: stealing credit card numbers targets payment data to commit fraud; hacking into switches breaches control of the network to intercept, reroute, or misuse calls; and wireless phone theft and fraud involves stealing devices or using stolen credentials to commit fraudulent charges.

Phone phreaking, in contrast, is a historical term for experimenting with or manipulating the signaling of the telephone network. While it can be illegal and can lead to other illicit activity, it’s regarded more as a hacking activity or exploration of the system rather than a direct form of telecom fraud focused on stealing services or money. That distinction is why it’s treated as not a form of telecommunications fraud in this context.
