What is SMTP Smuggling?:
- 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.
