Mental Jailbreak: When the System Trusts the User Too Much
Modern mobile operating systems are designed around one fundamental assumption: the user is both the owner and the greatest threat to the device. This paradox is at the core of every security model in Android and iOS. While vendors invest heavily in sandboxing, mandatory access control, and kernel hardening, a single decision made by…

Cache Side-Channel Attacks: When Time Itself Becomes a Leak
Modern computing systems rely on multilayered memory hierarchies designed for speed, not secrecy. CPU caches — L1, L2, L3 — exist to accelerate access to frequently used data. But that optimization introduces a blind spot: timing differences. Attackers can observe tiny delays in memory access and extract information that should never be accessible. No…

The Hidden Complexity of Secure Serialization & Deserialization in Modern Distributed Systems
Serialization looks simple on the surface — convert an object into a byte stream, transmit it, and reconstruct it on the other side. But in real distributed systems, serialization is not a neutral plumbing detail; it directly affects system reliability, performance, security, and long-term compatibility. Most production outages involving inter-service communication or data corruption…

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.…

Power and Electromagnetic Side Channels: Data Extraction Across Physical Gaps
1. Beyond Software Boundaries: The Invisible Leakage When people talk about cybersecurity, they usually imagine code vulnerabilities, not physical ones. Yet some of the most insidious data leaks come not from compromised networks but from the subtle energy a device emits as it operates. Power consumption fluctuations and electromagnetic (EM) radiation — normally just…
