Phishing
Explanation:
Phishing is one of the most common social engineering attacks in which the attacker disguises to be a trustworthy personnel in order to lure the victim or target into disclosing sensitive information such as passwords, credit card details and so on.
Phishing could be carried out via emails, telephones, or even text messages.
