Maroochy SCADA attack, 2013 Slide 3
Maroochy shire sewage system
• SCADA controlled system with 142 pumping
stations over 1157 sq km installed in 1999
• In 2000, the area sewage system had 47
unexpected faults causing extensive sewage
spillage
Maroochy SCADA attack, 2013 Slide 4
SCADA setup
Typical SCADA-controlled sewage system
This is not the system that was attacked
Maroochy SCADA attack, 2013 Slide 5
SCADA sewage control
• Special-purpose control computer at each
station to control valves and alarms
• Each system communicates with and is
controlled by central control centre
• Communications between pumping stations
and control centre by radio, rather than wired
network
Maroochy SCADA attack, 2013 Slide 6
What happened
More than 1m litres of untreated sewage released
into waterways and local parks
Maroochy SCADA attack, 2013 Slide 7
Technical problems
• Sewage pumps not operating when they
should have been
• Alarms failed to report problems to control
centre
• Communication difficulties between the
control centre and pumping stations
Maroochy SCADA attack, 2013 Slide 8
Insider attack
• Vitek Boden worked for Hunter Watertech
(system suppliers) with responsibility for the
Maroochy system installation.
• He left in 1999 after disagreements with the
company.
• He tried to get a job with local Council but
was refused.
Maroochy SCADA attack, 2013 Slide 9
Revenge!
• Boden was angry and decided to take
revenge on both his previous employer and
the Council by launching attacks on the
SCADA control systems
– He hoped that Hunter Watertech would be blamed
for the failure
• Insiders don’t have to work inside an
organisation!

actsBehindCyberSecurity.pdf
Maroochy SCADA attack, 2013 Slide 11
How it happened
• Boden stole a SCADA configuration program
from his employers when he left and installed
it on his own laptop
• He also stole radio equipment and a control
computer that could be used to impersonate a
genuine machine at a pumping station
• Insecure radio links were used to
communicate with pumping stations and
change their configurations
Maroochy SCADA attack, 2013 Slide 12
Incident timeline
• Initially, the incidents were thought to have
been caused by bugs in a newly installed
system
• However, analysis of communications
suggested that the problems were being
caused by deliberate interventions
• Problems were always caused by a specific
station id
Maroochy SCADA attack, 2013 Slide 13
Actions taken
• System was configured so that that id was not
used so messages from there had to be
malicious
• Boden as a disgruntled insider fell under
suspicion and put under surveillance
• Boden’s car was stopped after an incident
and stolen hardware and radio system
discovered
Maroochy SCADA attack, 2013 Slide 14
Causes of the problems
• Installed SCADA system was completely
insecure
– No security requirements in contract with
customer
• Procedures at Hunter Watertech were
inadequate to stop Boden stealing hardware
and software
• Insecure radio links were used for
communications
Maroochy SCADA attack, 2013 Slide 15
Causes of the problems
• Lack of monitoring and logging made
detection more difficult
• No staff training to recognise cyber attacks
• No incident response plan in place at
Maroochy Council
Maroochy SCADA attack, 2013 Slide 16
Aftermath
• On October 31, 2001 Vitek Boden was
convicted of:
– 26 counts of willfully using a computer to cause
damage
– 1 count of causing serious environment harm
• Jailed for 2 years

Maroochy water breach

  • 1. Maroochy SCADA attack, 2013 Slide 1 Cybersecurity Case Study Maroochy water breach http://www.slideshare.net/sommervi/cs5032- case-study-maroochy-water-breach
  • 2. Maroochy SCADA attack, 2013 Slide 2 Maroochy Shire Image credit: http://www.hinterlandtourism.com.au/attractions/the-maroochy-river/
  • 3. Maroochy SCADA attack, 2013 Slide 3 Maroochy shire sewage system • SCADA controlled system with 142 pumping stations over 1157 sq km installed in 1999 • In 2000, the area sewage system had 47 unexpected faults causing extensive sewage spillage
  • 4. Maroochy SCADA attack, 2013 Slide 4 SCADA setup Typical SCADA-controlled sewage system This is not the system that was attacked
  • 5. Maroochy SCADA attack, 2013 Slide 5 SCADA sewage control • Special-purpose control computer at each station to control valves and alarms • Each system communicates with and is controlled by central control centre • Communications between pumping stations and control centre by radio, rather than wired network
  • 6. Maroochy SCADA attack, 2013 Slide 6 What happened More than 1m litres of untreated sewage released into waterways and local parks
  • 7. Maroochy SCADA attack, 2013 Slide 7 Technical problems • Sewage pumps not operating when they should have been • Alarms failed to report problems to control centre • Communication difficulties between the control centre and pumping stations
  • 8. Maroochy SCADA attack, 2013 Slide 8 Insider attack • Vitek Boden worked for Hunter Watertech (system suppliers) with responsibility for the Maroochy system installation. • He left in 1999 after disagreements with the company. • He tried to get a job with local Council but was refused.
  • 9. Maroochy SCADA attack, 2013 Slide 9 Revenge! • Boden was angry and decided to take revenge on both his previous employer and the Council by launching attacks on the SCADA control systems – He hoped that Hunter Watertech would be blamed for the failure • Insiders don’t have to work inside an organisation!
  • 10. Maroochy SCADA attack, 2013 Slide 10 What happened? Image credit: http://www.pimaweb.org/conference/april2003/pdfs/MythsAndF actsBehindCyberSecurity.pdf
  • 11. Maroochy SCADA attack, 2013 Slide 11 How it happened • Boden stole a SCADA configuration program from his employers when he left and installed it on his own laptop • He also stole radio equipment and a control computer that could be used to impersonate a genuine machine at a pumping station • Insecure radio links were used to communicate with pumping stations and change their configurations
  • 12. Maroochy SCADA attack, 2013 Slide 12 Incident timeline • Initially, the incidents were thought to have been caused by bugs in a newly installed system • However, analysis of communications suggested that the problems were being caused by deliberate interventions • Problems were always caused by a specific station id
  • 13. Maroochy SCADA attack, 2013 Slide 13 Actions taken • System was configured so that that id was not used so messages from there had to be malicious • Boden as a disgruntled insider fell under suspicion and put under surveillance • Boden’s car was stopped after an incident and stolen hardware and radio system discovered
  • 14. Maroochy SCADA attack, 2013 Slide 14 Causes of the problems • Installed SCADA system was completely insecure – No security requirements in contract with customer • Procedures at Hunter Watertech were inadequate to stop Boden stealing hardware and software • Insecure radio links were used for communications
  • 15. Maroochy SCADA attack, 2013 Slide 15 Causes of the problems • Lack of monitoring and logging made detection more difficult • No staff training to recognise cyber attacks • No incident response plan in place at Maroochy Council
  • 16. Maroochy SCADA attack, 2013 Slide 16 Aftermath • On October 31, 2001 Vitek Boden was convicted of: – 26 counts of willfully using a computer to cause damage – 1 count of causing serious environment harm • Jailed for 2 years
