Chinese Hacking of iBahn Internet Services

Citing unexplained “intelligence data,” an unnamed “senior intelligence official,” and an anonymous “privacy security official,” Bloomberg News claims that iBahn—the company that runs Internet services for a bunch of hotel chains—has been hacked by the Chinese. The rest of the story is pretty obvious: all sorts of private e-mails stolen, corporate networks hacked via iBahn, China does lot of hacking, and so on. iBahn has denied the story.

Come on, people. I know that China hacking stories are plausible, but the bar for actual evidence should be higher than this.

Domain-in-the-Middle Attacks

It’s an easy attack. Register a domain that’s like your target except for a typo. So it would be countrpane.com instead of counterpane.com, or mailcounterpane.com instead of mail.counterpane.com. Then, when someone mistypes an e-mail address to someone at that company and you receive it, just forward it on as if nothing happened.

These are called “doppelganger domains.”

To test the vulnerability, the researchers set up 30 doppelganger accounts for various firms and found that the accounts attracted 120,000 e-mails in the six-month testing period.

The e-mails they collected included one that listed the full configuration details for the external Cisco routers of a large IT consulting firm, along with passwords for accessing the devices. Another e-mail going to a company outside the U.S. that manages motorway toll systems provided information for obtaining full VPN access into the system that supports the road tollways. The e-mail included information about the VPN software, usernames, and passwords.

They’re already being used to spy on companies:

Some of the companies whose doppelganger domains have already been taken by entities in China included Cisco, Dell, HP, IBM, Intel, Yahoo and Manpower. For example, someone whose registration data suggests he’s in China registered kscisco.com, a doppelganger for ks.cisco.com. Another user who appeared to be in China registered nayahoo.com ­ a variant of the legitimate na.yahoo.com (a subdomain for Yahoo in Namibia).

Kim said that out of the 30 doppelganger domains they set up, only one company noticed when they registered the domain and came after them threatening a lawsuit unless they released ownership of it, which they did.

He also said that out of the 120,000 e-mails that people had mistakenly sent to their doppelganger domains, only two senders indicated they were aware of the mistake. One of the senders sent a follow-up e-mail with a question mark in it, perhaps to see if it would bounce back. The other user sent out an e-mail query to the same address with a question asking where the e-mail had landed.

Defenses are few:

Companies can mitigate the issue by buying up any doppelganger domains that are still available for their company. But in the case of domains that may already have been purchased by outsiders, Kim recommends that companies configure their networks to block DNS and internal e-mails sent by employees that might get incorrectly addressed to the doppelganger domains. This won’t prevent someone from intercepting e-mail that outsiders send to the doppelganger domains, but at least it will cut down on the amount of e-mail the intruders might grab.

I suppose you can buy up the most common typos, but there will always be ones you didn’t think about—especially if you use a lot of subdomains.

Screenshots of Chinese Hacking Tool

It’s hard to know how serious this really is:

The screenshots appear as B-roll footage in the documentary for six seconds­between 11:04 and 11:10 minutes—showing custom built Chinese software apparently launching a cyber-attack against the main website of the Falun Gong spiritual practice, by using a compromised IP address belonging to a United States university. As of Aug. 22 at 1:30pm EDT, in addition to Youtube, the whole documentary is available on the CCTV website.

The screenshots show the name of the software and the Chinese university that built it, the Electrical Engineering University of China’s People’s Liberation Army­direct evidence that the PLA is involved in coding cyber-attack software directed against a Chinese dissident group.

The software window says “Choose Attack Target.” The computer operator selects an IP address from a list­it happens to be 138.26.72.17­and then selects a target. Encoded in the software are the words “Falun Gong website list,” showing that attacking Falun Gong websites was built into the software.

A drop-down list of dozens of Falun Gong websites appears. The computer operator chooses Minghui.org, the main website of the Falun Gong spiritual practice.

The IP address 138.26.72.17 belongs to the University of Alabama in Birmingham (UAB), according to an online trace.

The shots then show a big “Attack” button on the bottom left being pushed, before the camera cuts away.

Chinese Army Developed Online Wargame

This is a really weird story:

After setting up its own cyber-warfare team, China’s military has now developed its first online war game aimed at improving combat skills and battle awareness, state press said Wednesday.

“Glorious Mission” is a first-person shooter game that sends players on solo or team missions armed with high-tech weapons, the China Daily reported.

How is this different from any of the dozens of other first-person shooter games with realistic weapons?

And does “training” on these games really translate into the real world?

EDITED TO ADD (7/13): The original story by China Daily is more detailed and easier to follow.

Spear Phishing Attacks from China Against Gmail Accounts

Reporters have been calling me pretty much constantly about this story, but I can’t figure out why in the world this is news. Attacks from China—old news; attacks from China against Google—old news; attacks from China against Google Gmail accounts—old news. Spear phishing attacks from China against senior government officials—old news. There’s even a WikiLeaks cable about this stuff.

When I first read the story, I decided it wasn’t worth blogging about. Why is this news?

WikiLeaks Cable about Chinese Hacking of U.S. Networks

We know it’s prevalent, but there’s some new information:

Secret U.S. State Department cables, obtained by WikiLeaks and made available to Reuters by a third party, trace systems breaches—colorfully code-named “Byzantine Hades” by U.S. investigators—to the Chinese military. An April 2009 cable even pinpoints the attacks to a specific unit of China’s People’s Liberation Army.

Privately, U.S. officials have long suspected that the Chinese government and in particular the military was behind the cyber-attacks. What was never disclosed publicly, until now, was evidence.

U.S. efforts to halt Byzantine Hades hacks are ongoing, according to four sources familiar with investigations. In the April 2009 cable, officials in the State Department’s Cyber Threat Analysis Division noted that several Chinese-registered Web sites were “involved in Byzantine Hades intrusion activity in 2006.”

The sites were registered in the city of Chengdu, the capital of Sichuan Province in central China, according to the cable. A person named Chen Xingpeng set up the sites using the “precise” postal code in Chengdu used by the People’s Liberation Army Chengdu Province First Technical Reconnaissance Bureau (TRB), an electronic espionage unit of the Chinese military. “Much of the intrusion activity traced to Chengdu is similar in tactics, techniques and procedures to (Byzantine Hades) activity attributed to other” electronic spying units of the People’s Liberation Army, the cable says.

[…]

What is known is the extent to which Chinese hackers use “spear-phishing” as their preferred tactic to get inside otherwise forbidden networks. Compromised email accounts are the easiest way to launch spear-phish because the hackers can send the messages to entire contact lists.

The tactic is so prevalent, and so successful, that “we have given up on the idea we can keep our networks pristine,” says Stewart Baker, a former senior cyber-security official at the U.S. Department of Homeland Security and National Security Agency. It’s safer, government and private experts say, to assume the worst—that any network is vulnerable.

Two former national security officials involved in cyber-investigations told Reuters that Chinese intelligence and military units, and affiliated private hacker groups, actively engage in “target development” for spear-phish attacks by combing the Internet for details about U.S. government and commercial employees’ job descriptions, networks of associates, and even the way they sign their emails—such as U.S. military personnel’s use of “V/R,” which stands for “Very Respectfully” or “Virtual Regards.”

The spear-phish are “the dominant attack vector. They work. They’re getting better. It’s just hard to stop,” says Gregory J. Rattray, a partner at cyber-security consulting firm Delta Risk and a former director for cyber-security on the National Security Council.

Spear-phish are used in most Byzantine Hades intrusions, according to a review of State Department cables by Reuters. But Byzantine Hades is itself categorized into at least three specific parts known as “Byzantine Anchor,” “Byzantine Candor,” and “Byzantine Foothold.” A source close to the matter says the sub-codenames refer to intrusions which use common tactics and malicious code to extract data.

A State Department cable made public by WikiLeaks last December highlights the severity of the spear-phish problem. “Since 2002, (U.S. government) organizations have been targeted with social-engineering online attacks” which succeeded in “gaining access to hundreds of (U.S. government) and cleared defense contractor systems,” the cable said. The emails were aimed at the U.S. Army, the Departments of Defense, State and Energy, other government entities and commercial companies.

By the way, reading this blog entry might be illegal under the U.S. Espionage Act:

Dear Americans: If you are not “authorized” personnel, but you have read, written about, commented upon, tweeted, spread links by “liking” on Facebook, shared by email, or otherwise discussed “classified” information disclosed from WikiLeaks, you could be implicated for crimes under the U.S. Espionage Act—or so warns a legal expert who said the U.S. Espionage Act could make “felons of us all.”

As the U.S. Justice Department works on a legal case against WikiLeak’s Julian Assange for his role in helping publish 250,000 classified U.S. diplomatic cables, authorities are leaning toward charging Assange with spying under the Espionage Act of 1917. Legal experts warn that if there is an indictment under the Espionage Act, then any citizen who has discussed or accessed “classified” information can be arrested on “national security” grounds.

Maybe I should have warned you at the top of this post.

Euro Coin Recycling Scam

This story is just plain weird. Regularly, damaged coins are taken out of circulation. They’re destroyed and then sold to scrap metal dealers. That makes sense, but it seems that one- and two-euro coins aren’t destroyed very well. They’re both bi-metal designs, and they’re just separated into an inner core and an outer ring and then sold to Chinese scrap metal dealers. The dealers, being no dummies, put the two parts back together and sold them back to a German bank at face value. The bank was chosen because they accept damaged coins and don’t inspect them very carefully.

Is this not entirely predictable? If you’re going to take coins out of circulation, you had better use a metal shredder. (Except for pennies, which are worth more in component metals.)
