Phishing Email Checker

Use ChatGPT with Phishing Email Checker to check a suspected BEC email and produce the documentation needed to escalate it — an incident record for security, a clear advisory for the finance team, and a response to the executive whose identity was spoofed. ChatGPT formats the raw findings into stakeholder-ready communications.

Steps

Once connected (see setup above), use the Phishing Email Checker tool:

  1. Paste the email with full headers and specify that this is a suspected executive impersonation.
  2. Ask ChatGPT to run `check_email` via `phishing-email-checker`.
  3. Have ChatGPT produce an incident record for the security team with verdict, technical indicators, and severity.
  4. Ask for a separate brief advisory for the finance team explaining what happened and what they should do before acting on similar requests.

Example Prompt

Try this with ChatGPT using the Phishing Email Checker tool
Use phishing-email-checker to check this suspected CEO impersonation email: [paste full email with headers]. Produce (1) a security incident record with verdict, BEC indicators, and severity rating, and (2) a plain-English advisory for the finance team on how to verify executive requests before acting on them.

Tips

  • Produce both a technical incident record and a plain-English team advisory from the same analysis to save time.
  • Include the severity rating in the incident record — BEC attacks targeting finance warrant high or critical.
  • Send the advisory to the finance team proactively, not just reactively, to reduce future exposure.
