Social Engineering attacks continue to pose a significant risk to the corporate world with a growing level of sophistication. It is difficult to distinguish between authentic and phishing communication via email, chat, and phone. They pose a risk of exposing trade secrets and confidential communications and can create a chain of attack from lower-level employees up to executives. Therefore, we study this growing threat using real-world datasets to build baseline machine-learning models. Our TF-IDF models classify emails as phishing or safe, achieving accuracy above 90%. We build on this by exploring whether psychological manipulation and persuasion indicators can be measured to play a significant role in detecting phishing. Instead of relying solely on surface-level lexical features, we derive interpretable lexicon-based indicators of urgency, trust, greed, and other persuasion cues from the combined email dataset. By evaluating these manipulation-oriented features on their own, we measure how much signal they carry (ROC-AUC of 0.74 on a held-out test split) and test whether they transfer to held-out email sources.
