The top technology story at the end of last week involved multiple news sources reporting a cyber attack that penetrated a US public water system in Illinois. Here’s what we know, and what we don’t.
Question 1) What happened to prompt the concern?
Answer: An Illinois water system pump was (reportedly) turned on and off repeatedly until it failed.
According to the Breitbart article: Foreign cyber attack hits US Infrastructure: expert
“The Illinois Statewide Terrorism and Intelligence Center disclosed the cyber assault on a public water facility outside the city of Springfield last week but attackers gained access to the system months earlier according to Joseph Weiss (managing partner from Applied Control Solutions).
The network breach was exposed after cyber intruders burned out a pump.
‘No one realized the hackers were in there until they started turning on and off the pump,’ according to Weiss.”
Question 2) Are we sure that the pump failed as a result of a cyber attack?
Answer: No, but it looks likely. The Daily Mail (UK) reported: “The Department of Homeland Security confirmed that a water plant in Springfield, Illinois, had been damaged.
However spokesman Peter Boogaard said officials had yet to confirm that the pump failure was the result of a cyber-attack.”
Question 3) How did the hackers gain enough access to bring down the water pump?
Answer: According to a report from the Illinois Terrorism and Intelligence Fusion Center, cyber attackers broke into a software company’s database and got hold of user names and passwords of various control systems that run water plant computer equipment.
“The attackers are thought to have obtained the usernames and passwords to the system by first breaking into a computer belonging to the utility's SCADA software vendor. SCADA vendors often maintain a list of usernames and passwords for accessing systems at customer locations for support purposes. Anyone with those credentials can gain access to the customer system, which is what appears to have happened here.”
Question 4) Was anyone harmed or did customers lose water service?
Answer: No. Other pumps and/or systems maintained service during the pump failures.
Question 5) Why is this such a big deal? Why is this a top story around the world if no one was hurt?
Answer: The potential ramifications of having a confirmed (successful) cyber attack against (any) critical infrastructure are enormous. Besides the implications for our water, there are fears of attack against transportation, electricity or other important infrastructure sectors. Yes, each sector has plans for defense.
There are vulnerable critical infrastructure components, and there are many programs that attempt to protect these systems from a cyber or other attack. NERC and other organizations have spent millions of dollars to start building the smart grid, which may also be susceptible to a cyber attack.
If this failure is confirmed as a cyber attack, the sense of urgency will only increase. Many experts believe that a 21st Century “cyber war” is coming and will be like the previous “cold war” of the 20th Century.
Movies like Live Free or Die Hard (“Die Hard 4”) demonstrate a worst-case cyber attack scenario against critical infrastructure – but remember this is fiction which is overdone to entertain.
Question 6) Are there any other water systems or other utilities that were compromised by the same cyber incident?
Answer: This is still being investigated right now. Several sources believe that other systems may have been compromised. Either way, the implications to the wider Industrial Control System (ICS) and Supervisory Control and Data Acquisition (SCADA) community are huge.
If you need help, each sector has plans and programs, but you can start with this Critical Infrastructure Protection (CIP) website at DHS.
Question 7) Was this a cyber “test” by the bad guys? Is this the beginning of a dangerous hacker trend?
Answer: You decide. Time will give us the answer, but we’d better plan for the worst while we hope for the best. Nevertheless, this should be a cyber wake-up call for America.
