Pentesting ICS 101

Presented at BSidesLV 2023, Aug. 9, 2023, 10:30 a.m. (Unknown duration)

Do you want to learn how to hack Industrial Control Systems? Let's participate in the one and only CTF in which you really have to capture a flag, by hacking PLCs and taking control of a robotic arm! We'll start by explaining the basics of Industrial Control Systems : what are the components, how they work, the protocols they use… We'll learn how PLC work, how to program them, and how to communicate with them using Modbus, S7comm and OPCUA. Then we'll start hacking! Your goal will be to take control of a model train and robotic arms to capture a real flag! The CTF will be guided so that everyone learns something and gets a chance to get most flags!

Presenters:

  • Alexandrine Torrents
    Alexandrine Torrents is a cybersecurity expert at Wavestone. She started as a penetration tester, and performed several cybersecurity assessments on ICS. She worked on a few ICS models to demonstrate attacks on PLCs and developed a particular tool to request Siemens PLCs. Then, she started working at securing ICS, especially in the scope of the French military law, helping companies offering a vital service to the nation to comply with security rules. Now, Alexandrine works with different industrial CISOs on their cybersecurity projects: defining secure architectures, hardening systems, implementing detection mechanisms. She is also IEC 62443 certified and still performs assessments on multiple environments.
  • Arnaud SOULLIE
    Arnaud Soullié (@arnaudsoullie) is a Senior Manager at Wavestone, a global consulting company. For 13 years, he has been performing security assessments and pentests on all types of targets. He started specializing in ICS cybersecurity more than 10 years ago. He spoke and taught workshops at numerous security conferences on ICS topics : BlackHat Europe, BruCon, CS3STHLM, BSides Las Vegas, DEFCON… He is also the creator of the DYODE project, an open­source data diode aimed at ICS. He has been teaching ICS cybersecurity training since 2015.
