Modern ransomware uses lateral movement techniques to propagate through networks. Once inside, malware scans for shared drives, servers, and connected devices. It exploits permissions and vulnerabilities to reach critical systems. Enterprise environments can be fully encrypted within hours. Sophisticated attacks minimize detection and maximize disruption.
It matters because network-wide infections magnify damage. Isolation strategies are critical.
It also demonstrates why network segmentation is a top defense measure.
Ransomware can encrypt all systems in a network rapidly.
