A landmark presentation highlighting the inherent vulnerabilities in the Signaling System No. 7 (SS7) protocol. The talk demonstrates how attackers can locate mobile phones, track user movements, and manipulate network routing data globally, exploiting the legacy trust model of telecommunication networks. yes no no ss7-security intercepting sms via ss7 ss7 vulnerabilities training telecom network hacking https://www.youtube.com/embed/V9iPz3-g2L4 Tobias Engel https://videos.telcosec.net/videos/karsten-nohl-mobile-self-defense https://cdn.videos.telcosec.net/videos/covers/ai-1789241485405.jpg Mobile self-defense Karsten Nohl discusses active defensive tactics against mobile network attacks. The talk introduces tools like SnoopSnitch to help users detect network-level anomalies, IMSI catchers, and SMS/SS7 exploits, shifting from vulnerability discovery to community-driven defense. yes no no ss7-security imsi catcher detection ss7 firewall bypass telecom security training https://www.youtube.com/embed/nRdJ0vaQt0o Karsten Nohl https://videos.telcosec.net/videos/karsten-nohl-rooting-sim-cards https://img.youtube.com/vi/R9U0O0y_K9E/hqdefault.jpg Rooting SIM cards A deep technical presentation on SIM card security architectures. Nohl explains how weak DES/3DES configurations in SIM applets allow remote attackers to crack keys over OTA SMS, execute arbitrary code on the SIM OS, and compromise the subscriber profile. yes no no sim-security sim card hacking sim applet auditing ghost sim attack https://www.youtube.com/embed/R9U0O0y_K9E Karsten Nohl https://videos.telcosec.net/videos/chris-paget-practical-cellphone-spying https://cdn.videos.telcosec.net/videos/covers/ai-1789220343225.jpg Practical Cellphone Spying A classic demonstration of physical layer cellular vulnerabilities. Chris Paget showcases a functional, DIY IMSI catcher using low-cost hardware and open-source base station software, showing how devices are forced to downgrade to GSM and route calls through a rogue tower. yes no no imsi-catchers rogue base station attacks sdr over-the-air decoding imsi catcher detection https://www.youtube.com/embed/kYF94M150pU Chris Paget
