Led by Red Sift experts, this webinar takes a practical approach to the SubdoMailing (Subdo) campaign, including how the attack is possible and what members can do to protect themselves. This campaign sends malicious mail that is typically authenticated, from domains and subdomains that have been compromised through domain takeover and dangling DNS issues. Learn what technical DNS vulnerabilities make the attack possible, what tools you can use to uncover and fix misconfigurations to secure your organization against email fraud.
