Description
Multiple potential evasion techniques were observed in an email.
Attacker's Goals
Evasion techniques are used to avoid security scanners.
Investigative actions
- Review the headers and content for patterns or anomalies.
- Assess the email's context and attack techniques to determine the potential risk.
- Review the email headers and metadata of each flagged email to identify potential spoofing techniques or unusual routing patterns.
- Analyze any URLs or attachments in a secure sandbox environment to detect possible malware or phishing attempts.
- Engage potentially affected users to understand if any actions were taken in response to these emails, which could increase the overall risk.
- Document and escalate findings in case this is a broader phenomenon.
