Cyber security: CIA warns about industry hacking, extortion risks
SANS Institute comments follow on CIA process control and SCADA security presentation.
The CIA doesn’t normally discuss openly what it sees or what it does. So when a cyber security expert wants to speak publicly and for the record about cyber crime threats in the electric utility industry, people listen. Last month, Tom Donahue, the CIA’s top cyber security analyst, did just that at the SANS Institute 2008 SCADA and Process Control Summit. I caught up with Alan Paller, research director for SANS, and asked him what he carried away from that presentation.
Paller said the CIA asked to make this presentation, but SANS was not allowed to publicize its participation, or even say that Donahue was coming. “The news was that he came prepared and vetted to make the presentation,” Paller notes, “so that means they’ve moved past the stage where this is hypothetical in their minds, and they think it needs to be fixed. I was shocked that they were willing to do that. He said‘you can quote me,’ and he gave it to me in writing and signed it. Their message is that people need to act on this, and they wanted to give it a credible source.”
The substance of the presentation is that there have been actual cyber break-ins at utilities outside the U.S. where hackers have made extortion demands, and in at least one situation they caused an outage that affected multiple cities. The analysts suspect, but cannot confirm, that the hackers had inside knowledge. “The CIA measures the threat, not the vulnerability,” Paller adds. “They’re looking at who’s doing this and what kind of resources they have. If the CIA thinks it matters, it matters, at least to me. Utilities need to act on the threat.
“People pretend it’s not a problem by putting risks in boxes. Either‘I’m protected,’ or ‘They’re not going to target me,’ or ‘It’s not a big enough probability.’ The CIA’s job is to measure the extent to which people, either governments, terrorist groups, or organized crime, have gotten to the point where they know howto do it, can do it, and have figured out that they can make a buck or get data they want doing it. That’s got to be what happened.”
Paller says there are three main ways to make money by hacking. The first is spam, obtaining e-mail addresses for advertising or directly soliciting money. The second is getting into an individual’s machine to steal personal financial information. A new variation on that is “pump and dump,” where people’s online stock trading accounts are hijacked and used to pump up a stock price fraudulently. Those two account for many billions of dollars of illegal gain. Extortion, the third method of hacking is rapidly growing.
“Extortion is the biggest silent threat,” warns Paller. “Banks have been hit by it. Lots of e-commerce sites and virtually all online gambling sites are paying extortion. For utilities, it is the big threat. It has been a major crime category since at least 2001, and a friend of mine who runs this area for the FBI says they learn of at least one new cyber-extortion case every day. It’s a huge thing.”
Is there light at the end of the security tunnel? Paller says there is also good news that came out of the January summit. More on that next month.
The SANS Institute provides a wide variety of training and courses for cyber security. There will be a comprehensive seminar in Orlando, April 18-25 .
