A finance clerk receives an unexpected email urging an immediate change to vendor wire instructions. Which threat vector best describes this attack?
Select an answer to reveal the explanation.
Short Explanation
Urgent email, weird wire-change request, pressure on the clerk—that is phishing riding the inbox, not a USB left under a windshield or a chip-fab conspiracy. The vector is the message.
Full Explanation
Phishing is a message-based social-engineering vector commonly delivered by email to manipulate users into revealing information or performing risky actions such as changing payment instructions. The stem describes email content and urgency, which points to that human/message path. Removable-media drops, hardware supply-chain tampering, and attacks on offline backup media are different vectors and do not match an urgent wire-change email to a finance clerk.
