What can happen if a hospital patient monitor is hacked?

  1. Patient's medical information (#PHI) is exposed to the external.
  2. Since the monitor alarm is disabled, medical staff are not notified of emergency situations such as cardiac arrest or respiratory failure, so patients miss the golden time.
  3. Unauthorized modification of vital body parameters (heart rate, blood pressure, oxygen level, etc.) data can lead to misdiagnosis and incorrect treatment, and emergency surgeries are delayed.


"Ultimately, it threatens the lives of patients."

However, is it actually possible to hack these patient monitors that can be easily found in hospitals? Yes, it is definitely possible.


On Jan 30, regarding the 'Contec #CMS8000' patient monitor mentioned in the announcement by CISA and FDA, the #Team82 research team found a vulnerable design of the device and shared an attack PoC that exploited the flaw as follows. 


[Summary of Attack PoC]

Download malicious binary and overwrite executable to patient monitor file system with hardcoded IP address > Implement reverse shell payload with control code call and arbitrary code execution and remote shell access

Here are the recommendations for organizations using 'Contec CMS8000' patient monitor:

  1. Block all access to subnet 2_0_2.1_1_4.4.x/24 from internal network
  2. Avoid using hardcoded default IP address (2_0_2.1_1_4.4.1_1_9) for CMS and if unavoidable, prevent external routing of traffic through static routes or network segmentation
  3. Block outbound traffic to 2_0_2.1_1_4.4.1_2_0 to prevent PII/PHI leakage if 'HL7' feature is not used.

Don't confuse DCS, PLC and SCADA in front of OT specialists

DCS, PLC and SCADA are not the same. If you keep talking only about PLC security in front of the Oil&Gas industry executives where DCS is the main focus, they will not recognize you as a proper expert. We need to understand the characteristics of OT systems such as DCS, PLC, and SCADA accurately, also respect each OT culture uniquely and finally approach the sites in the right way. Don't be confused, here’s a clear and accurate explanation of DCS, PLC, and SCADA . 1. Distributed Control System (DCS) Concept A DCS (Distributed Control System) is an automated control system used for large-scale industrial processes that require continuous operation and high reliability. It consists of multiple controllers distributed throughout the system, which communicate with each other to manage complex processes. Key Features Used in large-scale, continuous processes (e.g., oil refineries, power plants). Decentralized control architecture with multiple controllers working together. Pr...

A comprehensive list of 20 threat scenarios in OT security along with detailed descriptions and detection rules that can help identify and respond to these threats. This playbook-style table covers different types of attacks—from unauthorized access to insider abuse—with corresponding rules and indicators to alert security teams. # Threat Scenario Detailed Description Detection Rules & Indicators 1 Unauthorized Remote Access Attempt An attacker uses stolen or weak credentials to access OT networks remotely. - Log Analysis: Monitor VPN/RDP logs for unusual login times, geolocation mismatches, and failed/successful login bursts. - User Behavior Analytics (UBA): Alert on deviations from normal remote access patterns. - Anomaly Detection: Trigger an alert when a remote session is initiated from an unusual IP or geographic region. 2 Malware/Ransomware Infiltration in OT Network Malicious code is introduced into the OT network via compromised endpoints or phishing, potentially encr...

Let's create our own ICS Labs in the VMs: A Step-by-Step Guide Building an Industrial Control System (ICS) lab in a virtualized environment allows security researchers, engineers, and penetration testers to safely simulate industrial networks, study threats, and test security defenses. Below is a detailed step-by-step guide to creating an ICS lab , including HMI, EWS, PLC, and other critical components. 1. Lab Architecture Overview Key Components in an ICS Lab: HMI: Graphical interface for controlling industrial processes. Engineering Workstation (EWS): Used to configure PLCs and SCADA systems. PLC: Controls physical processes (e.g., motors, valves). SCADA System: Supervisory control and monitoring of ICS networks. Historian: Logs and stores process data for analysis. Networking Components: Virtualized switches, routers, and firewalls to segment ICS networks. Attacker Machine: Kali Linux or Metasploit for penetration testing. 2. Choosing the Virtualization ...
