Скачать или смотреть SIM Cards Are a Security System — Until They’re Not | Deep Dive into SIM Attacks & eSIM Risks

Welcome back to KingTech.#CyberSecurity #SIMSecurity #eSIM #MobileSecurity

In this video, we completely deconstruct the SIM card — not as a simple piece of plastic, but as a hardware root of trust and a full secure microcomputer that underpins global mobile identity.

This is a deep technical breakdown designed for cybersecurity professionals, mobile security researchers, telecom engineers, and anyone serious about digital identity protection.

What you’ll learn in this video:

🔹 How the UICC (SIM card) actually works internally
🔹 Why the SIM is a secure element, not passive storage
🔹 Java Card OS vs proprietary SIM operating systems
🔹 The cryptographic authentication process (Ki, RAND, SRES, KC)
🔹 Why the secret key never leaves the SIM
🔹 How the SIM Application Toolkit (STK) expands the attack surface
🔹 How Simjacker abused the S@T browser via silent binary SMS
🔹 Why this attack bypassed Android & iOS completely
🔹 SIM-based attacks vs SIM swapping (administrative compromise)
🔹 Why SMS-based 2FA is still a catastrophic weak point
🔹 Detection strategies: rapid MNC rotation, OTP anomalies, SIM farms
🔹 How telecom-grade threat intelligence actually works
🔹 The architectural shift from UICC → eSIM (eUICC)
🔹 Why remote SIM provisioning (RSP) is the new attack surface
🔹 Security domains inside eSIM (ISD-R, ISD-P) explained
🔹 The hidden risks inside GSMA’s provisioning model
🔹 Why trust didn’t disappear — it just moved

This video shows a critical truth in modern cybersecurity:

Even hardware roots of trust are only as secure as the software, processes, and humans surrounding them.

If you work in cybersecurity, telecom security, digital forensics, OSINT, or identity protection, this knowledge is essential.
