Ben purchased a new smartphone and received some updates on it through the OTA method. He received two messages: one with a PIN from the network operator and another asking him to enter the PIN…

The scenario involves two SMS messages, one seemingly legitimate from the network operator and another malicious one prompting for the PIN, leading to abnormal phone behavior. This is an advanced form of SMS phishing (smishing) designed to bypass initial user skepticism by using context from a legitimate communication.

Bypass SSL pinning refers to techniques used to circumvent the security mechanism that prevents man-in-the-middle attacks on HTTPS connections to specific servers, which is not applicable to an SMS-based PIN attack.

Phishing is a general term for deceptive attempts to acquire sensitive information, but "Advanced SMS phishing" is a more specific and accurate description for this multi-step, context-aware SMS attack.

"Tap 'n ghost attack" is not a widely recognized or standard term for a mobile phone attack in cybersecurity; it seems to be a fabricated or niche term.
