– In 1999, Motorola, at my request, sent me to Silicon Valley for a week-long course in advanced Windows Win32 programming.
– During this course, I remember talking with another participant; a young computer whiz who was from the NSA.
– He talked about how they (the NSA computer guys) conducted red-team green-team battles to see who could infiltrate the other’s team’s computer systems.
– But the thing he talked about, that caught my interest the most, was when he said the hot new frontier was getting into firmware as a way of exerting control over computers remotely. It was a new idea that immediately fascinated me but once he saw my interest, I think he realized that he might be talking too much and clammed up. He avoided me for the rest of the week.
– The story, below, says that the technique of firmware infiltration may have been around since 2001. I’m sure I heard the sound of the other shoe dropping when I read that.
– The article says:
It is not clear how the NSA may have obtained the hard drives’ source code. Western Digital spokesman Steve Shattuck said the company “has not provided its source code to government agencies.” The other hard drive makers would not say if they had shared their source code with the NSA.
– I don’t find it all that mysterous. How hard would it be for the NSA to field computer-savvy agents directed to seek employment in these companies? Or, as the article says, to require the companies to provide their source code to the NSA for security reviews before the U.S. Government will allow it to be used in U.S. facilities?
– Once the NSA has the firmware’s source code, they can modify it and then intercept the firm’s drives in shipment and refresh the firmware on the intercepted drives with the NSA’s new stuff … that does everything the old firmware does … and a bit more.
– The interception-during-shipment technique was outed over a year ago as being one of their favorite techniques though in that case it had to do with routers.

The US National Security Agency has figured out how to hide spying software deep within hard drives made by Western Digital, Seagate, Toshiba and other top manufacturers, giving the agency the means to eavesdrop on the majority of the world’s computers, according to cyber researchers and former operatives.
That long-sought and closely guarded ability was part of a cluster of spying programs discovered by Kaspersky Lab, the Moscow-based security software maker that has exposed a series of Western cyberespionage operations.
Kaspersky said it found personal computers in 30 countries infected with one or more of the spying programs, with the most infections seen in Iran, followed by Russia, Pakistan, Afghanistan, China, Mali, Syria, Yemen and Algeria. The targets included government and military institutions, telecommunication companies, banks, energy companies, nuclear researchers, media, and Islamic activists, Kaspersky said.
The firm declined to publicly name the country behind the spying campaign, but said it was closely linked to Stuxnet, the NSA-led cyberweapon that was used to attack Iran’s uranium enrichment facility. The NSA is the agency responsible for gathering electronic intelligence on behalf of the United States.
A former NSA employee told Reuters that Kaspersky’s analysis was correct, and that people still in the intelligence agency valued these spying programs as highly as Stuxnet. Another former intelligence operative confirmed that the NSA had developed the prized technique of concealing spyware in hard drives, but said he did not know which spy efforts relied on it.
NSA spokeswoman Vanee Vines declined to comment.
Kaspersky published the technical details of its research on Monday, which should help infected institutions detect the spying programs, some of which trace back as far as 2001.
The disclosure could further hurt the NSA’s surveillance abilities, already damaged by massive leaks by former contractor Edward Snowden. Snowden’s revelations have hurt the United States’ relations with some allies and slowed the sales of US technology products abroad.
The exposure of these new spying tools could lead to greater backlash against Western technology, particularly in countries such as China, which is already drafting regulations that would require most bank technology suppliers to proffer copies of their software code for inspection.
TECHNOLOGICAL BREAKTHROUGH
According to Kaspersky, the spies made a technological breakthrough by figuring out how to lodge malicious software in the obscure code called firmware that launches every time a computer is turned on.
Disk drive firmware is viewed by spies and cybersecurity experts as the second-most valuable real estate on a PC for a hacker, second only to the BIOS code invoked automatically as a computer boots up.
“The hardware will be able to infect the computer over and over,” lead Kaspersky researcher Costin Raiu said in an interview.
Though the leaders of the still-active espionage campaign could have taken control of thousands of PCs, giving them the ability to steal files or eavesdrop on anything they wanted, the spies were selective and only established full remote control over machines belonging to the most desirable foreign targets, according to Raiu. He said Kaspersky found only a few especially high-value computers with the hard-drive infections.
Kaspersky’s reconstructions of the spying programs show that they could work in disk drives sold by more than a dozen companies, comprising essentially the entire market. They include Western Digital, Seagate, Toshiba, IBM, Micron Technology and Samsung.
Western Digital, Seagate and Micron said they had no knowledge of these spying programs. Toshiba and Samsung declined to comment. IBM did not respond to requests for comment.
GETTING THE SOURCE CODE
Raiu said the authors of the spying programs must have had access to the proprietary source code that directs the actions of the hard drives. That code can serve as a roadmap to vulnerabilities, allowing those who study it to launch attacks much more easily.
“There is zero chance that someone could rewrite the [hard drive] operating system using public information,” Raiu said.
Concerns about access to source code flared after a series of high-profile cyberattacks on Google Inc and other US companies in 2009 that were blamed on China. Investigators have said they found evidence that the hackers gained access to source code from several big US tech and defense companies.
It is not clear how the NSA may have obtained the hard drives’ source code. Western Digital spokesman Steve Shattuck said the company “has not provided its source code to government agencies.” The other hard drive makers would not say if they had shared their source code with the NSA.
Seagate spokesman Clive Over said it has “secure measures to prevent tampering or reverse engineering of its firmware and other technologies.” Micron spokesman Daniel Francisco said the company took the security of its products seriously and “we are not aware of any instances of foreign code.”
According to former intelligence operatives, the NSA has multiple ways of obtaining source code from tech companies, including asking directly and posing as a software developer. If a company wants to sell products to the Pentagon or another sensitive US agency, the government can request a security audit to make sure the source code is safe.
“They don’t admit it, but they do say, ‘We’re going to do an evaluation, we need the source code,'” said Vincent Liu, a partner at security consulting firm Bishop Fox and former NSA analyst. “It’s usually the NSA doing the evaluation, and it’s a pretty small leap to say they’re going to keep that source code.”
Kaspersky called the authors of the spying program “the Equation group,” named after their embrace of complex encryption formulas.
The group used a variety of means to spread other spying programs, such as by compromising jihadist websites, infecting USB sticks and CDs, and developing a self-spreading computer worm called Fanny, Kasperky said.
Fanny was like Stuxnet in that it exploited two of the same undisclosed software flaws, known as “zero days,” which strongly suggested collaboration by the authors, Raiu said. He added that it was “quite possible” that the Equation group used Fanny to scout out targets for Stuxnet in Iran and spread the virus.
