State-Owned Chinese Firms Hired Military Hackers for IT Services

The DOJ's historic indictment provides some rare insight into China's cyber espionage operations.

Amid the details of the specific charges the US government is leveling against five members of a Chinese military hacking team was a bit of information that provided a rare peek into the inner workings of state-run cyber espionage teams: A Chinese government-owned company allegedly hired one of the defendants to build a database to store stolen intelligence about its competitors.

According to the DOJ indictment, Huang Zhenyu was hired between 2006 and 2009 or later to do programming work for one of the companies (referred to as "SOE-2" in the indictment). Huang was allegedly tasked with constructing a "secret" database to store intelligence about the iron and steel industry, as well as information about US companies.

"Chinese firms hired the same PLA Unit where the defendants worked to provide information technology services," according to the indictment, which the US Department of Justice unsealed Monday. "For example, one SOE involved in trade litigation against some of the American victims herein hired the Unit, and one of the co-conspirators charged herein, to hold a 'secret' database to hold corporate 'intelligence.'"

The for-hire database project sheds some light on the operations of China's most prolific hacking unit, Unit 61398 of the Third Department of China's People's Liberation Army (also known as APT1), where the alleged hackers work. US Attorney General Eric Holder announced an unprecedented move Monday: The Justice Department had indicted the five men with the military unit for allegedly hacking and stealing trade secrets of major American steel, solar energy, and other manufacturing companies, including Alcoa, Allegheny Technologies Inc., SolarWorld AG, Westinghouse Electric, and US Steel, as well as the United Steel Workers Union.

"One of the companies hired APT1. That would be like GE hiring the NSA," says Richard Bejtlich, chief security strategist for FireEye and an expert on the so-called APT1 group. "They built a database. To me, that is interesting that they hired the military unit to [build it] and get the stolen information in it."

What's unclear, he says, is how the US discovered that detail of the operation. "How do we know about that? Did we use our intel to figure it out?"

Huang also registered and managed domain accounts that his co-defendants used to break into US company networks, and faces charges for managing the infrastructure used in the hacking incidents, according to the indictment. In all, the indictment against Huang and his fellow defendants contains 31 criminal counts, including ID theft, hacking, economic espionage, and theft of trade secrets. The charges carry prison sentences of five to 15 years each.

Tom Kellerman, chief cybersecurity officer for Trend Micro, said in an email interview that the for-hire tactic used by APT1/Unit 61398 mirrors the "service-based economy of scale" that has evolved out of Eastern Europe's cybercrime scene, namely that of the Russian Cyber Arms Bazaars. "They have learned to appreciate both opportunity cost and comparative advantage, thus emulating the hacking service-based economy of Eastern Europe," he said. "Oftentimes they use the very effective crime kits and RATs that were originally produced in Europe for the purposes of bank heists and apply those to IP theft. If you observe the metamorphosis of SpyEye and Citadel, this speaks to that reality."

So if a state-sponsored Chinese steel company hires a military hacking unit to do some work for it, who pays the tab? "The company is paid by the military," Kellerman said. "Many of these companies are merely shell companies."

Despite the high profile of China's Unit 61398/APT1, it's just one of many such units there. "They get the most attention because they are the most prolific, and they go after the most industries," says Bejtlich, who is also a nonresident senior fellow at the Brookings Institution. "But they are not the A Team."

China's equivalent to the NSA would be a collection of military units such as 61398. "These guys get attention because they are everywhere and in some ways are noisy," he says. "There may be some groups that are much quieter, that we are less likely to know about."

Yesterday, FireEye released additional details on the APT1/Unit 61398 group. The information provides further evidence that the attackers work out of China; 98.2% of the IP addresses used to log into hop points came from networks based in Shanghai.

The war within
Interesting article, this is a cyber war and I wish the mainstream media would hone in on this point. Best pratices in this field are often hard to identify, I would encourage you to read how companies like OPSWAT are introducing multi-scanning technologies to the frontlines

Re: the jury is still out -- literally
Marilyn, you are right, this is the tip of the iceberg. The majority of victims of cyber espionage ignores that its data are stolen by foreign state-sponsored hackers. Cyber espionage is a common practice, practically every government adopts it to steal sensitive information and intellectual property.

This, is the tip of the iceberg. This is only the indictment. I can't wait to findout what we will learn when (or if) this case goes to trial.

Re: Great Factual read by Ms. Higgins--thank you
Thanks, @mmcgann334. Much of the problem is the human factor. Most attacks by Chinese cyberespionage actors come via convincing spearphishing emails. A user in one of the orgs opens a link or an attachment, and so it begins. That doesn't mean that companies can't do a better job of locking down their sensitive data and catching the bad guys before they exfiltrate the information, however. Somehow, that didn't happen with these steel companies.

Great Factual read by Ms. Higgins--thank you
It is frightening to think that American companies like Westinghouse are an open book to  the the Chinese and how easy it is to obtain information.  What is going on with the security infrastructure in the U.S? Why is it so easy to break security codes?

Re: Time to Take Security More Seriously
Agreed, the ones you need to worry about are the ones you never see. The people at defcon are there for a reason, to gain notarity.

Time to Take Security More Seriously
This highlights the need for American companies to take storage and security of their data seriously.  If your trade secrets are located on systems that are 'net-connected, you're 50% on your way to having the data stolen.  I'm often surprised how many managers (some of them IT) feel it is archaic to have an offline policy for critical data stores, using encrypted storage to transfer/share files and buying non-electronic safes for storing those drives in.  I hope our American government cyber-elite aren't too distracted by these "loud" foreign teams, though.  The most efficient cyber-criminals are often the ones who never appeared at Defcon, published an exploit or sat in a chat room; guys with offline data stores, encrypted storage and old school safes, no doubt.
