Advanced Persistent Threats (APT) on Mobile and Network Systems
Advanced Persistent Threats (APTs) represent the highest tier of targeted cyberattacks: long-term, strategic intrusions executed by highly skilled adversaries, often state-sponsored groups or well-funded criminal organizations. Their goal is simple: remain inside a system for as long as possible while silently gathering intelligence, manipulating assets, or preparing for strategic disruption. Unlike common malware or…

Mobile banking malware & overlay attacks: what they are, why they work, and how to stop them
Short version: modern Android banking trojans steal credentials and authorize fraud by placing fake UI layers over real banking apps (or by abusing Accessibility), capturing input and bypassing controls. This attack vector is old, effective, and still widely abused — stop treating it like “user error.” Fix the product and the server, harden the…

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,…
