The thesis of Prof. Dr.-Ing. Christoph Saatjohann, titled “Practical (In)Security of IoT and Medical IT Systems”, explores critical vulnerabilities in IoT and medical ecosystems through six academic papers. Key focus areas include:
- ⌚ STALK: Security Analysis of Smartwatches for Kids
- 💔 Listen to Your Heart: Evaluation of the Cardiologic Ecosystem
- ⛑️ Security of Medical Protocols in Hospitals
- 🤒 SICKPATH: Simulating Cyber Attacks on Patient Treatment
- 🚘 Grand Theft App: Digital Forensics of Vehicle Assistant Apps
You Should Know:
1. Analyzing Smartwatch Vulnerabilities (STALK)
- Use Wireshark to intercept Bluetooth Low Energy (BLE) traffic from smartwatches:
sudo wireshark -k -i bluetooth
- Check for unencrypted data leaks with Btlejack:
btlejack -c -a <TARGET_MAC>
2. Testing Medical Protocol Security
- Simulate HL7/MLLP protocol attacks with Metasploit:
use auxiliary/scanner/healthcare/hl7 set RHOSTS <hospital_IP> run
- Detect weak DICOM configurations using dcmtk:
dcmdump <DICOM_IP> --scan-directories
3. Vehicle App Forensics (Grand Theft App)
- Extract APK data from connected car apps:
apktool d car_app.apk -o output_dir
- Analyze network traffic with mitmproxy:
mitmproxy -p 8080 --mode transparent
4. Simulating Hospital Cyberattacks (SICKPATH)
- Use ClinicAV (a hospital attack simulator):
python3 clinicav.py --target <hospital_IP> --attack ransomware
- Check for exposed PACS systems with nmap:
nmap -p 104,11112 --script dicom-ping <IP_RANGE>
What Undercode Say:
Medical IoT and automotive systems are prime targets due to legacy protocols and poor encryption. Key mitigations:
– Patch Management: Use `apt-get upgrade` (Linux) or `wuauclt /updatenow` (Windows) for medical devices.
– Network Segmentation: Isolate IoT devices via VLANs (vconfig add eth1 10).
– Forensic Readiness: Log critical events with journalctl -u medical_service --since "1 hour ago".
– Car App Security: Block unauthorized OTA updates via firewall (iptables -A OUTPUT -p tcp --dport 443 -j DROP).
Expected Output:
A hardened IoT/medical infrastructure with monitored BLE traffic, encrypted DICOM data, and segmented networks.
