Jason, a cybersecurity analyst in the incident response team, begins investigating several complaints from employees who received emails urgently requesting wire transfers to an overseas account. The emails appeared to come from the company’s CEO, using a tone of authority and pressure to bypass standard procedures. Upon closer inspection, Jason identifies that the sender's email address includes a minor alteration in the domain name—a form of domain spoofing. He examines the email headers, confirms the falsified sender identity, and cross-checks with the actual CEO’s activity logs to ensure there was no internal compromise. Immediately, Jason blocks the sender’s IP address at the firewall level, alerts the finance department to prevent any unauthorized transactions, and issues a company-wide advisory about the impersonation attempt. What type of phishing is Jason handling?
