DeltaCorp, a global e-commerce company, recently received an email sent to the financial department.

Email-header analysis should be the primary investigative step because headers contain technical routing and sender information that can expose spoofing or impersonation. ECIH email-incident analysis includes examining message headers, originating IP information, sender details, routing paths, and other metadata to determine whether a suspicious message is authentic. An attacker can easily imitate executive language, display names, signatures, and visual formatting, so apparent professionalism does not establish legitimacy. Reviewing previous emails may provide supporting context but is less conclusive than technical metadata. Scanning the mail server for malware addresses a different possible incident and does not directly validate the message ' s origin. Contacting the referenced vendor can be useful later through independently verified channels, but the most direct forensic method is to examine the header and identify inconsistencies in the actual sending infrastructure.
