A junior accountant who clicked a deceptive email link would be a victim of a phishing attack. This type of attack involves tricking the user into giving sensitive information or installing malware.
If a junior accountant clicked on a link within an email that appeared to come from the head of the accounting department, and as a result their device was compromised, this would be classified as a phishing attack. Phishing is a type of social engineering where attackers send fraudulent messages designed to trick individuals into divulging sensitive information or into unwittingly downloading harmful software. Hackers use phishing to lure victims by impersonating trustworthy entities, as demonstrated by the email seemingly sent from the department head.
