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…

Ghost Instances in Distributed Systems Invisible Resilience or Architectural Illusion?
Introduction Modern distributed systems are built to survive failure, overload, and hostile environments. As architectures become more complex, engineers explore patterns that go beyond traditional autoscaling, redundancy, and observability. One such concept—often discussed in security-critical circles is the idea of Ghost Instances: service replicas that remain dormant or invisible under normal conditions and activate…

When Silence Becomes a Signal: Attacks Emerging From Network Quiet Zones
Advanced intrusions rarely announce themselves. In fact, some of the most dangerous breaches begin with the opposite: a sudden absence of the traffic patterns you expect. Modern networks create predictable rhythms ARP chatter, DNS lookups, routine broadcast noise, service heartbeats. When those patterns collapse, the silence isn’t calm; it’s a warning. 1. The Hidden…

When Cryptography Depends on Noise, Not Data: The Hidden Risk in Quantum-Safe Systems
Quantum-safe cryptography is often promoted as the long-term shield against quantum attacks, but a critical blind spot is rarely discussed: some of these schemes fundamentally rely on noise and noise is a physical phenomenon, not a mathematical one.Once your security depends on unpredictable errors, anyone who can control those errors can start bending the…

Zombie Processes: Dead Code That Still Haunts the System
In operating systems, not every threat is loud. Some are silent, subtle, and buried deep in the process table. Zombie processes fall exactly into that category: tasks that have already finished execution but refuse to disappear. They’re technically dead, yet still present a residue of poor process management that can grow into a system-wide…
