What it means

Email attack incident response addresses phishing, business email compromise, malicious attachments, impersonation, mailbox abuse, and related identity compromise.

Why it matters

The visible message may be only the entry point; responders must evaluate accounts, sessions, forwarding rules, endpoints, payments, and recipients.

Practical focus

  • Preserve the message and delivery metadata
  • Identify all recipients and interactions
  • Secure affected identities and sessions
  • Remove persistence and notify business owners

Common mistakes

  • Deleting the message before preserving evidence
  • Resetting a password without revoking sessions
  • Checking only the first recipient
  • Ignoring financial and external communications impact
