Hidden Protocols in Networks: Beyond TCP/IP
Modern network security is still heavily shaped by assumptions made decades ago: traffic flows over well-known ports, protocols are explicit, and malicious behavior is noisy. Advanced attackers exploit exactly these assumptions. By using hidden or lesser-known protocol techniques, they turn the network into a gray zone where traditional visibility breaks down. The Illusion of…

Hidden Log Manipulation & Tamper Chains: Why Modern Systems Fail Without Cryptographically Verifiable Logging
In any distributed system, logs are the only surviving witnesses when something goes wrong. Code can fail silently, containers can restart, agents can hang, and monitoring dashboards can mislead, but logs capture ground truth — or at least, that’s the assumption. In reality, logs are frequently the weakest security link, and adversaries know this.…

Side-Channel Attacks on Mobile and IoT what they are, why they matter, and how to defend against them
Side-channel attacks are the ugly truth most developers don’t want to face: they extract secrets without breaking crypto math or getting privileged access — by observing physical or microarchitectural side effects (timing, power consumption, EM emissions, cache behavior, sensors, etc.). On constrained devices like phones and IoT nodes this problem is worse because hardware…

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,…
