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…

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…
