SMTP (Simple Mail Transfer Protocol) serves as the backbone of email communication.
Cybercriminals exploit SMTP by manipulating end-of-data sequences during email transmission, enabling the transmission of impersonated emails.
Impersonation Attacks and Vulnerability:
Impersonation attacks are facilitated by SMTP smuggling.
Unaware recipients are susceptible to falling prey to this social engineering scam, emphasizing the need for recognizing and preventing SMTP smuggling via awareness training.
Security Measures and Collaboration:
Some providers, like Microsoft, have deployed patches to address the threat, while others may still be exposed.
Organizations should prioritize comprehensive security awareness training, leveraging holistic platforms like PhishingBox.
Collaborative efforts between security researchers, industry players, organizations, and end users enhance awareness and enact proactive security measures.
