Ransomware attack / endpoint

FIREWALL MISCONFIGURATION · OPEN PORT 3389 · WEAK CREDENTIALS

Threat scenario:

An routine firewall rule change accidentally exposes RDP port 3389 directly to the internet. An automated scanner detects the open port within minutes. Over six hours, an attacker systematically brute-forces the admin password gaining domain administrator access and complete control over every connected system in the organisation.

Our Assessment

Exposed RDP is one of the most common entry points for ransomware groups and entirely preventable with correct firewall hygiene.

Disabling public-facing RDP, enforcing MFA on all remote access, and deploying Privileged Access Workstations close this exposure completely and eliminate the attack surface.

Our SIEM detects brute-force patterns instantly, triggering automated account lockout and firewall rules to stop the attack before domain compromise occurs.
