CEH v13 identifies spear-phishing as one of the most effective and targeted social engineering methods. It involves crafting highly personalized messages that reference real events, internal processes, or upcoming activities to build credibility and reduce suspicion. In this scenario, referencing board meetings—an event executive assistants frequently handle—creates a believable and urgent context for the request. CEH emphasizes that personalization significantly increases success rates because recipients perceive the sender as someone with legitimate access to internal information. A phone call impersonating IT support (Option B) is less convincing for retrieving agenda access-specific credentials. Mass phishing (Option C) lacks personalization and is easily flagged. LinkedIn social engineering (Option D) is long-term and less effective for obtaining immediate credentials. Therefore, a tailored spear-phishing email is the most effective approach.
