Brief: Researchers find way to detect ConfickerResearchers find way to detect Conficker
NSM vs The CloudBy Richard Bejtlich
A blog reader posted the following comment to my post Network Security Monitoring Lives:
How do you use NSM to monitor the growing population of remote, intermittently connect mobile computing devices? What happens when those same computers access corporate resource hosted by a 3rd party such as corporate SaaS applications or storage in the cloud?
This is a great question. The good news is we are already facing this problem today. The answer to the question can be found in a few old principles I will describe below.
- Something is better than nothing. I've written about this elsewhere: computer professionals tend to think in binary terms, i.e., all or nothing. A large number of people I encounter think 'if I can't get it all, I don't want anything." That thinking flies in the face of reality. There are no absolutes in digital security, or analog security for that matter. I already own multiple assets that do not strictly reside on any single network that I control. In my office I see my laptop and Blackberry as two examples.
Each could indeed have severe problems that started when they were connected to some foreign network, like a hotel or elsewhere. However, when the obtain Internet access in my office, I can watch them. Sure, a really clever intruder could program his malware to be dormant on my systems when I am connected to "home." How often will that be the case? It depends on my adversary, and his deployment model. (Consider malware that never executes on VMs. Hello, malware-proof hosts that only operate on VMs!)
The point is that my devices spend enough time on a sufficiently monitored network for me to have some sense that I could observe indicators of problems. Of course I may not know what those indicators could be a priori; cue retrospective security analysis. - What is the purpose of monitoring? Don't just monitor for the sake of monitoring. What is the goal? If you are trying to identify suspicious or malicious activity to high priority servers, does it make sense to try to watch clients? Perhaps you would be better off monitoring closer to the servers? This is where adversary simulation plays a role. Devise scenarios that emulate activity you expect an opponent to perform. Execute the mission, then see if you caught the red team. If you did not, or if your coverage was less than what you think you need, devise a new resistance and detection strategy.
- Build visibility in. When you are planning how to use cloud services, build visibility in the requirements. This will not make you popular with the server and network teams that want to migrate to VMs in the sky or MPLS circuits that evade your NSM platforms. However, if you have an enterprise visibility architect, you can build requirements for the sort of data you need from your third parties and cloud providers. This can be a real differentiator for those vendors. Visibility is really a prerequisite for "security," anyway. If you can't tell what's happening to your data in the cloud via visibility, how are you supposed to validate that it is "secure"?
I will say that I am worried about attack and command and control channels that might reside within encrypted, "expected" mechanisms, like updates from the Blackberry server and the like. I deal with that issue by not handling the most sensitive data on my Blackberry. There's nothing novel about that.
Response to 60 Minutes Story "The Internet Is Infected"
By Richard Bejtlich
I just watched the 60 Minutes story The Internet Is Infected. I have mixed feelings about this story, but I think you can still encourage others to watch and/or read it. Overall I think the effect will be positive, because it often takes a story from a major and fairly respected news source to grab the attention of those who do not operationally defend networks.
I'd like to outline the negative and positive aspects of the story, in my humble point of view.
The negative aspects are as follows:
- I detest the term "infected." Computers in 2009 are not "infected." They are compromised by malware operated by a human with an objective. The malware is a tool; it is not the end goal. In the late 1990s I enjoyed defending networks because the activity I monitored was caused by a human, live on the Internet, whose very keystrokes I could watch. At the beginning of this decade I despaired as human action was drowned in a sea of malware that basically propagated but did little otherwise. Since the middle of the decade we have had the worst of both worlds; when I see malware I know there is a human acting through it for malicious purposes. I detest "infection" because the term implies we can apply some antiseptic to the wound to "clean it." In reality the malware's operator will fight back, resist "cleaning," and maintain persistence.
- Cue the "teenage hacker." I thought we were collectively making progress away from the pasty-faced teenager in the parental basement. It seems the popular consciousness has now moved to the pasty-faced teenager in Russia, courtesy of 14-year-old "Tempest" in the 60 Minutes video. Never mind the organized crime, foreign intelligence, and economic espionage angles. Two other groups are definitely going to be upset by this: Chinese hackers and insider threats. Actually, not hearing a word about the latter makes me feel happy inside.
- "I thought I had a good enough firewall." GROAN. Hearing people talk about their firewalls and anti-virus was disheartening. I almost thought Vint Cerf was going to spill the beans on the easiest way to avoid Conficker when he said the following:
I’ve been on the Net ever since the Net started, and I haven’t had any of the bad problems that you’ve described," Cerf replied...
Because I don't use Windows! Say it Vint! Oh well.
The positive aspects are as follows:
- Hello security awareness. Stories like this wake people up to the problems we face every day. Sure Conficker is just the latest piece of malware, definitely not "one of the most dangerous threats ever," as said on TV. At the very least this story should enable a conversation between management and security operations.
- Client-side exploitation via socially-engineered and social network attacks were demonstrated. Good for Symantec to show that Morley Safer owns Leslie Stahl via Facebook. Better yet, 60 Minutes even used the term "owned"!
- Real consequences were demonstrated. I am very glad that Symantec showed just what an intruder can do to an owned computer. Keystroke logging, screen scraping, sensitive informatiomn retrieval, the works. They didn't even mention opening and closing the CD tray or activating the Webcam. That would have been cool, though.
Expect a few questions about this tomorrow at work!

New security standard MashSSL builds application trustApplication mashups are gaining traction in the enterprise. There's no doubt that productivity can be enhanced when new functionality can be delivered quickly and conveniently by combining information from multiple sources. However, there's a trade-off in application security. Mashups hold the potential to introduce a new network attack vector. A proposed new standard called MashSSL could eliminate the security concerns, making enterprise mashups as secure as any SSL transaction.

Latest cloud storage hiccups prompts data security questionsThe pitch from providers of hosted storage services sounds enticing. Instead of what these provider call the inherent risks in using hard drives or DVDs to store data, users are better off paying pay a small fee and backing up data in the cloud. Cloud storage providers pledge that putting valuable data into their hands is like keeping money in a bank.

Chinese cyberespionage network runs across 103 nations
By jhruska@arstechnica.com (Joel Hruska) on Tibet
The existence and operation of massive, coordinated, government-affiliated online espionage networks is typically the province of television or the silver screen, rather than the subject of research. In the real world, even a direct link between online and offline action (Russia's invasion of Georgia and the simultaneous online attacks against that country are a good example) is not enough to automatically prove that the government behind the one is automatically behind the other. We've covered the rise of hacktivism previously on Ars; as more citizens come online, we'll undoubtedly see more of this type of crowdsourced aggression in the future.
Researchers in Toronto, however, may have actually discovered and tracked a hacking effort that can be traced back to a foreign intelligence network—China's, in this case—over the past ten months. The team, which is affiliated with the Munk Centre for International Studies, has published an extensive report on the activities of what they dub GhostNet. Their investigation took place from June 2008 through March of 2009, and focused on allegations that the Chinese had engaged in systemic online espionage activities against the Tibetan community. GhostNet was spread through the use of a wide variety of Trojans, many of which were controlled through a program nicknamed gh0st RAT (Remote Access Tool).
MyID.is takes logical step, links Web ID with real world
By david@arstechnica.com (David Chartier) on OpenID
The notion of online verification is certainly nothing new, though it is also not for everyone. Many users prefer the anonymity of the Web for any number of (sometimes nefarious) reasons. For others, a centralized login and identity management resource is an ideal solution for the modern times, and these kinds of systems are blossoming. OpenID itself is experiencing broad adoption by the largest players in technology and the Web, though consumers have not been as quick to hop on board. Facebook Connect has taken off as both a single sign-on launchpad and activity syndication mechanism, but the newly launched, London-based MyID.is may be the first to tackle the challenge of tying our Web personas with our real world identities.
MyID.is' approach is simple, though it takes some time to get set up. The company is an OpenID provider, and it adds a key element of real world ID verification by charging a small, random setup fee (between €2 and €5) to your credit card, then mailing a code to your home address. Much like PayPal's account creation process, you must enter the fee amount and snail mail code on MyID.is' website, and the name on your card must match the name you registered with. After you successfully enter all this information, you'll have a MyID.is-provided OpenID URL and identity with which to badge your blog (pictured above), forum comments, Facebook profile, and just about any other online activity to prove that the content you generate is really coming from you.
