A Week Inside a Compromised Network: How Attacks Unfold Over Time
A breach of a network is rarely a single, isolated event. In many cases, attackers quietly establish a foothold and then gradually expand their access over days or even weeks. What begins as a small, unnoticed intrusion can escalate into a full-scale compromise, putting sensitive data, critical systems, and privileged credentials at serious risk.
