The gh0stEdit Attack: How Hackers Hide in Docker Image Layers

A sophisticated attack technique called "gh0stEdit" allows hackers to hide malicious code within Docker image layers, evading standard security scans. By exploiting Docker's layered architecture, attackers insert malicious files between legitimate layers that activate when containers run. Over 1,500 compromised images have been discovered on public repositories in the past six months. Organizations are advised to implement multi-layered security approaches, including layer-by-layer scanning, runtime behavior monitoring, and signed image verification to protect against this threat.
