Ghost Telephonist Link Hijack Exploitations in 4G LTE CS Fallback

This course aims to educate participants on the vulnerability in CSFB (Circuit Switched Fallback) in 4G LTE networks known as 'Ghost Telephonist.' The learning outcomes include understanding how the authentication step is missing in the CSFB procedure, leading to potential communication hijacking. Participants will learn about exploitations that can be carried out based on this vulnerability, especially when calls or SMS are not encrypted or weakly encrypted. The course teaches skills related to identifying and exploiting vulnerabilities in 4G LTE networks. The teaching method involves a presentation introducing the vulnerability and its implications. This course is intended for individuals interested in cybersecurity, network security, and telecommunications.
