A clandestine group of sophisticated Chinese hackers have infected scores of sites on the Web and stolen documents from industrial and government organizations with surgical precision, according to a Dell SecureWorks study released last week.
Dubbed “Threat Group 3390,” the cybergang has used infected websites of some 100 organizations across the globe — in Iran, Iraq, Zambia, Italy, Afghanistan, Qatar and Ecuador, as well as in other parts of Europe, South America, the Middle East and Africa — to trap their targets.
The group placed code on each site that redirected visitors to a malicious site, according to the report. A site visitor who had an IP address that was of interest to the hackers would be served an exploit kit upon returning to the site.
To avoid detection, the hackers did not always use the compromised sites to serve code, the report notes. They would stop using a specific site altogether for a time in order to stay under the radar.
“All around the globe, they found websites that were related to topics of interest to their targets,” said Aaron Hackworth, SecureWorksCounter Threat Unit special operations team leader.
“Then they would find vulnerabilities in those websites and modify them to either directly deliver an exploit or redirect visitors to a website where the exploit could be delivered,” he told TechNewsWorld.
Several factors support the assertion that TG3390 is a Chinese operation, the report notes. One of the favorite tools of the group is PlugX, which has a server side component written exclusively in Mandarin Chinese.
The gang also uses the Chinese Baidu search engine for reconnaissance.
In addition, a primary target of the group has been the Uyghur cultural website. The Uyghurs — a Muslim minority group located primarily in the Xinjiang region of China — have been in conflict with the Chinese government. Targeting the Uyghurs is not likely to be a priority for threat groups outside of China.
What’s more, the cyberposse was active between 4:00 and 09:00 UTC time, or 12:00 to 17:00 local time in China, which maps to the second half of the workday there.
“Any one of those things by itself wouldn’t have been enough for us to say we have a moderate degree of confidence in the China connection, but in aggregate, we can say it’s an active group operating out of China,” Hackworth said.
“As far as who is controlling them, who’s pulling their strings, we can’t determine that,” he added.
Once TG3390 penetrates a network, it spends a good deal of time getting comfortable with its surroundings before actually stealing any data.
“Only after preparing for eviction and orienting themselves with a network would they start looking for the data they were targeting,” Hackworth said.
A common trait TG3390 shares with other savvy cybergangs is an aversion to malware.
“A lot of these more sophisticated groups will use malware initially but as quickly as they can, they get rid of the malware and use stolen credentials, Web shells or things that are much less likely to be detected by endpoint security controls,” Hackworth explained.
“At some point, defenders will detect malware and remove it,” he added. “They’re less likely to detect folks using methods that don’t show up on traditional endpoint security solutions.”
After thorough reconnaissance and foundation preparation, TG3390 sets about stealing data, the study notes. The Web robbers focus on a particular project or projects a target organization is working on. Then they steal every related file.
“They are more surgical than some of the other groups we’ve observed in the past. There are groups that come in and just take everything and hope they can get some value out of it,” Hackworth said.
“That level of surgical targeting shows a level of maturity and discipline in this group that has not been seen in other groups,” he pointed out.
Russians Ransack Pentagon
The Chinese aren’t alone in engaging in data theft, as the Pentagon highlighted last week, when it blamed Russian hackers for ransacking the unclassified mail system of the Joint Chiefs of Staff.
The breach was detected about July 25, according to a report in The Washington Post.
The Pentagon immediately disabled the email system, which is used by about 4,000 military and civilian personnel, in an attempt to contain the damage, the paper said.
The attack was similar to one last fall that enabled hackers to rifle through the unclassified email systems at the White House and the State Department. Those intrusions also were blamed on Russians.
In this latest intrusion, which was launched through a spearphishing campaign that enticed targets to click on infected links in emails, only unclassified emails were exposed, and the damage did not appear to be significant, Pentagon officials said.
The Joint Chiefs’ classified networks were unaffected, they noted.
“The Russians clearly knew what they were looking for, which implies this was a precision attack,” said Richard Blech, CEO of Secure Channels.
“The hackers gathered highly sensitive data in a very short time,” he told TechNewsWorld. “Considering the high-level target, this is just a small piece of a bigger puzzle that should be leaving everyone alarmed.”
While the public should be relieved that the classified systems weren’t compromised, there is still room for concern, observed Tellagraff CEO Mark Graff, former CISO at Nasdaq and Lawrence Livermore Labs.
“As someone who has used classified systems, you can’t be sure that there is no classified material on the unclassified network,” he told TechNewsWorld. “It’s very easy to bleed over and have classified material put on the unclassified system.”
Moreover, even unclassified material can be valuable to the intruders.
“If you can get in and rummage around in an email system, you can use that information for more spear phishing,” Graff said.
“You can also get information on staffing dispositions, logistics, personnel and political intrigue — competition among groups in the Pentagon and the White House,” he added.
