This likely AI-generated credential phishing attack features an impersonation of a Netflix customer service representative, who informs the recipient that their Netflix subscription is ending soon. To continue service, the recipient needs to update their information to renew their account using the provided link, likely leading to a malicious site where payment details or other sensitive information are at risk. Utilizing a range of social engineering techniques, the attacker references the recipient by name in the email's subject line and breaks into an authentic domain, "," to launch this attack, making it multifaceted and sophisticated. If the recipient is quickly glancing at this email, seeing the word Zendesk might trick them into believing it is legitimate since many large companies utilize 3rd party customer support platforms like Zendesk. 

Legacy email security tools struggle to detect this email as an attack because of the sender domain's reputation, the lack of attachments, and the advanced social engineering tactics used by the attacker. Modern, AI-powered security tools accurately identify this email as an attack because they analyze the links, content, and sender.

How Does This Attack Bypass Email Defenses?

This email attack bypasses traditional security solutions for multiple reasons, including the following:

  • Sender Domain Reputation: The email comes from a domain ( that legacy security tools may not flag as malicious. This legitimate domain has been compromised and can trick legacy tools into thinking it's safe.
  • Lack of Attachments: The email does not contain any attachments. Many legacy security tools focus on scanning attachments for malicious content, so an email without attachments might not trigger these security checks.
  • Social Engineering Tactics: The email uses social engineering tactics, such as urgency ("your current subscription is coming to an end soon") and familiarity (Netflix), to trick the recipient into clicking the link. These tactics often bypass legacy tools that focus on technical indicators of an attack.
