Hardware-Level Cryptography with Intel SGX: Securing the Untrusted World
Introduction In a world where malware, rootkits, and insider threats constantly evolve, traditional software-based security is no longer enough. Intel Software Guard Extensions (SGX) takes a different path — embedding cryptographic isolation directly into the processor. By creating a trusted execution environment (TEE) within the CPU, SGX allows sensitive code and data to run…

Hypervisor-level Exploits: Why VM Isolation Isn’t a Silver Bullet
Virtualization is everywhere: cloud providers, enterprise datacenters, developer laptops, CI runners. It looks safe — each workload sits in its own virtual machine (VM), separated by the hypervisor. That visual separation lulls engineers into false confidence. Here’s the blunt truth: if the hypervisor breaks, your isolation is meaningless. Hypervisor-level exploits (VM escape, hypervisor compromise,…
