Grid Highly Vulnerable to Hack





This is a real danger, but its public disclosure pretty well wakes up everyone to get it fixed and also determine other vulnerabilities.  The delays are normal as large organizations are simply not on a war footing and have to go get approvals as well as develop capability to repair the problem.

If an attack does take place there will be a mad panic to fix the problem.  In the meantime all this is an open invitation to our enemies to play although they would have to co-opt professionals to assist.  It is obviously not quite that easy rogue hackers would have already caused problems.

This is at least fixable.  Protection against an EM pulse is quite another matter as that needs to be regulated into existence to protect installed infrastructure and ensure new infrastructure has protection.  Our vulnerability is something that will then wane albeit slowly.

Report: Massive Vulnerability Detected In National Power Grids: “There Is No Way to Stop This”

If you think that our multi-billion dollar electrical power grids are secure and capable of withstanding a coordinated attack, think again.

According to one group of engineers, the grid is so vulnerable that it wouldn’t even require a skilled hacker to compromise. In fact, when Adam Crain and Chris Sistrunk decided to test some new software they were developing they identified a vulnerability so serious that it could literally blind operational controllers to such an extent that they would be locked out of monitoring systems and unable to maintain grid integrity.

The consequences, according to the engineers who note they are in no way security specialists, could be a total downing of the national power grid with nodes across the nation being taken over all at once. Moreover, the same systems used to maintain the U.S. power grid are also being used in other industries, like water treatment facilities.

You’d think that such a vulnerability would be a top priority for the Department of Homeland Security, considering they are spending millions of dollars and promoting their coming Grid Ex exercise in November.

But you’d be wrong. The kicker is that when Crain and Sistrunk advised the DHS Industrial Control Systems Cyber Emergency Response Team, they got what essentially amounts to no response. It took Homeland Security a full four months before they even acknowledged the problem.

The two engineers who discovered the vulnerability say little is being done.

Adam Crain and Chris Sistrunk do not specialize in security. The engineers say they hardly qualify as security researchers. But seven months ago, Mr. Crain wrote software to look for defects in an open-source software program.

The program targeted a very specific communications protocol called DNP3, which is predominantly used by electric and water companies, and plays a crucial role in so-called S.C.A.D.A. (supervisory control and data acquisition) systems. Utility companies use S.C.A.D.A. systems to monitor far-flung power stations from a control center, in part because it allows them to remotely diagnose problems rather than wait for a technician to physically drive out to a station and fix it.

Mr. Crain ran his security test on his open-source DNP3 program and didn’t find anything wrong. Frustrated, he tested a third-party vendor’s program to make sure his software was working. The first program he targeted belonged to Triangle MicroWorks, a Raleigh, North Carolina based company that sells source code to large vendors of S.C.A.D.A. systems.

It broke instantly.

“When Adam told me he broke Triangle, I worried everything else was broken,” said Mr. Sistrunk.

Over the course of one week last April, the two tested Mr. Crain’s software across 16 vendors’ systems. They did not find a single system they couldn’t break.

By the end of the week, the two had compiled a 20-page report replete with vulnerabilities in 16 different system vendors for the Department of Homeland Security’s Industrial Control Systems Cyber Emergency Response Team, I.C.S.-C.E.R.T., which notifies vendors of vulnerabilities and issues public advisories.

And then, they waited. It would take I.C.S.-C.E.R.T. another four months to issue a public advisory for Triangle MicroWorks’ system.

…D.H.S. did not return a request for comment.
Mr. Crain found that he could actually infiltrate a power station’s control center from afar. An attacker could use that capability to insert malware to take over the system, and like Stuxnet, the computer worm that took out 20 percent of Iran’s centrifuges, inflict actual physical harm.

“This is low-hanging fruit,” said Mr. Crain. “It doesn’t require some kind of hacker mastermind to understand the protocol and do this.”

What makes the vulnerabilities particularly troubling, experts say, is that traditional firewalls are ill-equipped to stop them. “When the master crashes it can no longer monitor or control any and all of the substations,” said Dale Peterson, a former N.S.A. employee who founded Digital Bond, a security firm that focuses on infrastructure.

“There is no way to stop this with a firewall and other perimeter security device today.”


When outgoing DHS head Janet Napolitano suggested that a cyber attack on the nation’s power grid is imminent, she meant it.

They know that these systems are vulnerable, and the steps needed to protect the grid from cyber attacks and other potential hazards like a Super EMP or a severe geo-magnetic event would cost in the multiple billions of dollars to fix.

The fact of the matter is that DHS and the vendors who produce these software control systems are dragging their feet, leaving the entire country vulnerable.

Crain and Sistrunk are not hackers or security experts. They are software engineers and they were able to compromise our entire national power grid and water utility systems from remote locations.

What do you think China, Russia, and rogue hackers are capable of doing?

If you don’t think they’ve mapped our entire grid and its vulnerabilities you are kidding yourself.

This is deadly serious.

And when we say deadly, we mean it, because according to a report from the Center for Security Policy presented to Congress in 2010, if our power grid were to be taken offline for an extended period of time, 9 out of 10 Americans would be dead within a year.

There would be no way to transport food because gas stations pumps would be inoperable. And even if they did work, the commerce systems which makes the exchange of goods possible would be offline. Couple that with water utilities not functioning due to lack of electricity, and we’re talking about a worst-case scenario so bad that this country may never recover.

Former Congressman Roscoe Bartlet has urged those who can to move out of major cities for this reason.

Electrical Grid Is Called Vulnerable to Power Shutdown


Over the past few months, the discoveries of two engineers have led to a steady trickle of alarms from the Department of Homeland Security concerning a threat to the nation’s power grid. Yet hardly anyone has noticed.

The advisories concern vulnerabilities in the communication protocol used by power and water utilities to remotely monitor control stations around the country. Using those vulnerabilities, an attacker at a single, unmanned power substation could inflict a widespread power outage.

Still, the two engineers who discovered the vulnerability say little is being done.

Adam Crain and Chris Sistrunk do not specialize in security. The engineers say they hardly qualify as security researchers. But seven months ago, Mr. Crain wrote software to look for defects in an open-source software program. The program targeted a very specific communications protocol called DNP3, which is predominantly used by electric and water companies, and plays a crucial role in so-called S.C.A.D.A. (supervisory control and data acquisition) systems. Utility companies use S.C.A.D.A. systems to monitor far-flung power stations from a control center, in part because it allows them to remotely diagnose problems rather than wait for a technician to physically drive out to a station and fix it.

Mr. Crain ran his security test on his open-source DNP3 program and didn’t find anything wrong. Frustrated, he tested a third-party vendor’s program to make sure his software was working. The first program he targeted belonged to Triangle MicroWorks, a Raleigh, North Carolina based company that sells source code to large vendors of S.C.A.D.A. systems. It broke instantly.

Mr. Crain called Mr. Sistrunk, an electrical engineer, to see if he could help Mr. Crain test his program on other systems.

“When Adam told me he broke Triangle, I worried everything else was broken,” said Mr. Sistrunk.

Over the course of one week last April, the two tested Mr. Crain’s software across 16 vendors’ systems. They did not find a single system they couldn’t break.

By the end of the week, the two had compiled a 20-page report replete with vulnerabilities in 16 different system vendors for the Department of Homeland Security’s Industrial Control Systems Cyber Emergency Response Team, I.C.S.-C.E.R.T., which notifies vendors of vulnerabilities and issues public advisories.

And then, they waited. It would take I.C.S.-C.E.R.T. another four months to issue a public advisory for Triangle MicroWorks’ system.

Triangle MicroWorks’ engineering manager Greg Godlevski said that during those four months, the company developed a number of its own tests to look for defects in its software and fix them. Mr. Godlevski said the company waited for confirmation from Mr. Crain that the problem had been fixed, then met with I.C.S.-C.E.R.T. several times to review and comment on the government advisory.

“We take any reported problems discovered in our products very seriously,” Mr. Godlevski said. “We expend a lot of effort adding levels of security to our protocols and ensuring that they comply to the published specifications.”

D.H.S. did not return a request for comment.

Over the course of those four months, Mr. Crain and Mr. Sistrunk  found vulnerabilities in an additional nine vendors’ systems.

Like most security alerts, there are some caveats to this concern for the safety of electric facilities: Mr. Peterson’s company, Digital Bond, sells consulting services to assess and improve the security of S.C.A.D.A. systems.

Mr. Crain also has an interest. In March, he plans to release a free version of his security test, but for now he is charging vendors to use his program. (Mr. Crain would not disclose pricing, since it differed for each vendor based on vendor size, saying only that he charged in the “thousands” though he said he charged far less than commercial services like WurldTech Security, which charges tens of thousands of dollars for similar programs.)

“We haven’t found anything we haven’t broken yet,” Mr. Crain said in an interview. At minimum, the two discovered that they could freeze, or crash, the software that monitors a substation, thereby blinding control center operators from the power grid. Mr. Crain likened that capability to “a bank robber being in a bank vault with the camera frozen.”

In the case of one vendor, Mr. Crain found that he could actually infiltrate a power station’s control center from afar. An attacker could use that capability to insert malware to take over the system, and like Stuxnet, the computer worm that took out 20 percent of Iran’s centrifuges, inflict actual physical harm.


“This is low-hanging fruit,” said Mr. Crain. “It doesn’t require some kind of hacker mastermind to understand the protocol and do this.”


What makes the vulnerabilities particularly troubling, experts say, is that traditional firewalls are ill-equipped to stop them. “When the master crashes it can no longer monitor or control any and all of the substations,” said Dale Peterson, a former N.S.A. employee who founded Digital Bond, a security firm that focuses on infrastructure. “There is no way to stop this with a firewall and other perimeter security device today. You have to let DNP3 responses through.”


Even more troubling, Mr. Peterson said, is that most DNP3 communications aren’t regulated. The original version of DNP3 worked on serial communications — a way of transmitting data usually found in things like coaxial cables — and is still widely deployed in large systems, particularly substations around the country. But current cybersecurity regulations, governed by the North American Electric Reliability Corporation’s (N.E.R.C.) Critical Infrastructure Protection Committee (C.I.P.C.) are focused on Internet Protocols, or I.P. protocols, and specifically exclude serial communications and the equipment that uses them from meeting any security requirements.


“Why isn’t D.H.S., N.E.R.C., and the DNP3 committee telling vendors they need to fix this now and utility owners they need to get this patched A.S.A.P.?” Mr. Peterson said.


To date, D.H.S. has posted nine advisories, several of them for software used by major players in the electric sector.

“This is a systemic problem,” Mr. Crain said. “Most of the top five utilities use this software and just because a patch is available, doesn’t necessarily mean that utilities are applying them.”
