1. LET’S TALK BACNET SCADASIDES LAST MINUTE CHANGE MICHAEL TOECKER Mikhail Turcher, big fanci pantsie

2. BACNET PROTOCOL CYBER OVERVIEW Ooooh… Cybah Cybah Cybah Overfuncher!

3. BASICS BACnet is short for Building Automation and Control Network BACnet developed started in 1985, was adopted by ASHRAE in 1995, and is now a major component of most Building Automation systems. Basically, it’s a protocol used for control, monitoring, and interoperability for automation systems used in buildings BACnet controllers are basically PLCs, controlling HVAC, Lighting, Security, and other systems you will find in large buildings BACnet networks are… complicated and strange for IT folks…. More in a few. Like nearly every ICS protocol, BACnet is also insecure by design It supports encryption… It does, 56-Bit DES. Is this really encryption anymore? You can also set a password. Maybe. Kinda, it’s like 6 characters with no logging, and doesn’t protect against most bacnet commands Basi….. Sknnnnzzzz….

4. WE APOLOGIZE FOR THE FAULT IN THE SUBTITLES.. THOSE RESPONSIBLE HAVE BEEN SACKED

5. PRIOR ART @WarezJoe - ShmooCon 2013: How To Own A Building: Exploiting the Physical World With Bacnet - http://www.youtube.com/watch?v=d3jtmv6Y9ukhttp://www.youtube.com/watch?v=d3jtmv6Y9uk Redpoint – Bacnet Discovery NSE - http://www.digitalbond.com/blog/2014/03/26/redpoint-discover-enumerate- bacnet-devices/ Dis presentation needs more goats

6. A BACNET CONTROLLER Ethernet Port Universal Inputs RS485 Analog Outputs Digital Inputs POWAH! RS232!

7. OTHER BACNET DEVICE I tells him to Pressy the butensies!! Press them!!! He does not.

8. BACNET NETWORKS

9. BACNET OBJECTS

10. CHARACTERISTICS OF BACNET PACKETS ADD WIREHSHARK CAPTURE UDP 47808

11. WHAT YOU NEED TO COMMUNICATE You need: 1.An Instance ID – An ID that uniquely identifies a device 2.Network ID – Think of it like a subnet, allows separation of groups of devices 3.The Object – A Logical construct holding the data you want After that, you can make a request to a Specific Device on a Specific Network.

12. CHARACTERISTICS OF BACNET PACKETS Object-Name Request Magic Number 0x810A

13. CHARACTERISTICS OF BACNET PACKETS Magic Number 0x810A Object-Name Response

14. INTERESTING THINGS TO DO WITH BACNET REGISTER_FOREIGN_DEVICE()

15. FOREIGN DEVICE REGISTRATION

16. 59 WILL GET YOU 505 Potential Issues: 1.Requires Spoofing 2.Requires ability to change port numbers.

17. LOTS OF BACNET ON THE NET

18. FOCUSED ON THE BACNET NETWORK This opinion is shortsighted. Here’s why….

19. CONCLUSION Why BACNET? Cause I work on Critical Infrastructure, and it’s nice to pwn something that I don’t get yelled at for owning. Cause it’s interesting, and fun, and gets me some attention to demonstrate I know what I’m doing. Cause it can have some interesting consequences for owners and others. Why not? It’s still ICS

20. QUESTIONS? Thanks, Mike Heh. Goatsies. Always End with Goatsies.
