More on the Captured U.S. Drone

There’s a report that Iran hacked the drones’ GPS systems:

“The GPS navigation is the weakest point,” the Iranian engineer told the Monitor, giving the most detailed description yet published of Iran’s “electronic ambush” of the highly classified US drone. “By putting noise [jamming] on the communications, you force the bird into autopilot. This is where the bird loses its brain.”

The “spoofing” technique that the Iranians used—which took into account precise landing altitudes, as well as latitudinal and longitudinal data—made the drone “land on its own where we wanted it to, without having to crack the remote-control signals and communications” from the US control center, says the engineer.

The Aviationist has consistently had the best analysis of this, and here it talks about the Tehran Times report that Iran has four Israeli and three U.S. drones.

Hack Against SCADA System

A hack against a SCADA system controlling a water pump in Illinois destroyed the pump.

We know absolutely nothing here about the attack or the attacker’s motivations. Was it on purpose? An accident? A fluke?

EDITED TO ADD (12/1): Despite all sorts of allegations that the Russians hacked the water pump, it turns out that it was all a misunderstanding:

Within a week of the report’s release, DHS bluntly contradicted the memo, saying that it could find no evidence that a hack occurred. In truth, the water pump simply burned out, as pumps are wont to do, and a government-funded intelligence center incorrectly linked the failure to an internet connection from a Russian IP address months earlier.

The end of the article makes the most important point, I think:

Joe Weiss says he’s shocked that a report like this was put out without any of the information in it being investigated and corroborated first.

“If you can’t trust the information coming from a fusion center, what is the purpose of having the fusion center sending anything out? That’s common sense,” he said. “When you read what’s in that [report] that is a really, really scary letter. How could DHS not have put something out saying they got this [information but] it’s preliminary?”

Asked if the fusion center is investigating how information that was uncorroborated and was based on false assumptions got into a distributed report, spokeswoman Bond said an investigation of that sort is the responsibility of DHS and the other agencies who compiled the report. The center’s focus, she said, was on how Weiss received a copy of the report that he should never have received.

“We’re very concerned about the leak of controlled information,” Bond said. “Our internal review is looking at how did this information get passed along, confidential or controlled information, get disseminated and put into the hands of users that are not approved to receive that information. That’s number one.”

Notice that the problem isn’t that a non-existent threat was over hyped in a report circulated in secret, but that the report became public. Never mind that if the report hadn’t become public, the report would have never been revealed as erroneous. How many other reports like this are being used to justify policies that are as erroneous as the data that supports them?

Advanced Persistent Threat (APT)

It’s taken me a few years, but I’ve come around to this buzzword. It highlights an important characteristic of a particular sort of Internet attacker.

A conventional hacker or criminal isn’t interested in any particular target. He wants a thousand credit card numbers for fraud, or to break into an account and turn it into a zombie, or whatever. Security against this sort of attacker is relative; as long as you’re more secure than almost everyone else, the attackers will go after other people, not you. An APT is different; it’s an attacker who—for whatever reason—wants to attack you. Against this sort of attacker, the absolute level of your security is what’s important. It doesn’t matter how secure you are compared to your peers; all that matters is whether you’re secure enough to keep him out.

APT attackers are more highly motivated. They’re likely to be better skilled, better funded, and more patient. They’re likely to try several different avenues of attack. And they’re much more likely to succeed.

This is why APT is a useful buzzword.

Fake Documents that Alarm if Opened

This sort of thing seems like a decent approach, but it has a lot of practical problems:

In the wake of Wikileaks, the Department of Defense has stepped up its game to stop leaked documents from making their way into the hands of undesirables—be they enemy forces or concerned citizens. A new piece of software has created a way to do this by generating realistic, fake documents that phone home when they’re accessed, serving the dual purpose of providing false intelligence and helping identify the culprit.

Details aside, this kind of thing falls into the general category of data tracking. It doesn’t even have to be fake documents; you could imagine some sort of macro embedded into Word or pdf documents that phones home when the document is opened. (I have no idea if you actually can do it with those formats, but the concept is plausible.) This allows the owner of a document to track when, and possibly by what computer, a document is opened.

But by far the biggest drawback from this tech is the possibility of false positives. If you seed a folder full of documents with a large number of fakes, how often do you think an authorized user will accidentally double click on the wrong file? And what if they act on the false information? Sure, this will prevent hackers from blindly trusting that every document on a server is correct, but we bet it won’t take much to look into the code of a document and spot the fake, either.

I’m less worried about false positives, and more concerned by how easy it is to get around this sort of thing. Detach your computer from the Internet, and the document no longer phones home. A fix is to combine the system with an encryption scheme that requires a remote key. Now the document has to phone home before it can be viewed. Of course, once someone is authorized to view the document, it would be easy to create an unprotected copy—screen captures, if nothing else—to forward along,

While potentially interesting, this sort of technology is not going to prevent large data leaks. But it’s good to see research.

Full Extent of the Attack that Compromised RSA in March

Brian Krebs has done the analysis; it’s something like 760 companies that were compromised.

Among the more interesting names on the list are Abbott Labs, the Alabama Supercomputer Network, Charles Schwabb & Co., Cisco Systems, eBay, the European Space Agency, Facebook, Freddie Mac, Google, the General Services Administration, the Inter-American Development Bank, IBM, Intel Corp., the Internal Revenue Service (IRS), the Massachusetts Institute of Technology, Motorola Inc., Northrop Grumman, Novell, Perot Systems, PriceWaterhouseCoopers LLP, Research in Motion (RIM) Ltd., Seagate Technology, Thomson Financial, Unisys Corp., USAA, Verisign, VMWare, Wachovia Corp., and Wells Fargo & Co.
