Moscow, Russia (CNN) -- Russia tested its fifth-generation Sukhoi fighter jet in the Russian Far East on Friday. The plane, provisionally called T-50, is the country's first fighter jet based on the stealth technology and is viewed by military experts as the Russian answer to the American F-35 and F-22 jets.

Recently, I had the chance to be interviewed for two different podcasts.
In Risky Business #138, I had the opportunity to chat with show host Patrick Gray about the recent Google hack, why they may have been using IE6 and what this means for information security in general. This episode also features an interview with Dan Geer on the future of computing which I highly recommend.

In the eternal quest to create easy ways for systems to communicate with people and other systems, embedded device manufacturers have created new protocols. One of the first was UPnP, or Universal Plug and Play, which has had its share of security problems. The latest protocol to emerge is called HNAP, or Home Network Administration Protocol. Its goal is to "allow advanced programmatic configuration and management by remote entities." The protocols primary purpose is to aid device manufacturers in supporting remote devices such as printers and wireless routers. HNAP allows remote configurations to be both viewed and changed remotely using an HTTP SOAP-based protocol. While this sounds wonderful, someone decided to push the "easy" button:
"HNAP was designed to be a simple, light weight protocol that is easy to implement inside of small cost-constrained hardware such as network routers, cameras and other small devices. Because the protocol is based on existing HTTP-SOAP standards, it is very flexible and easily extensible."
The first phrase that raises a red flag for security-minded people is "simple, light weight". This almost always means that in order to simplify the design to make it "light weight", the first thing to go is security. Further reading of the Cisco Systems whitepaper on HNAP reveals an entire section dedicated to "Protocol Security", which states:

Providing credentials to Nessus so that it can log into the systems being scanned is a very effective method of vulnerability scanning. It enables the scanner to provide a patch audit, perform local operating system identification, portscanning, and audit the configuration files present on the target. For web application testing, credentials allow Nessus to enumerate and detect vulnerabilities inside the application, ensuring that a larger percentage of functionality is tested. The following two videos cover how to perform both network-based credentialed scanning, and provide credentials for web application scanning using Nessus 4.2.

Recent investigations into the Google "Aurora" incident uncovered evidence that Chinese attackers used a 0-day exploit for Internet Explorer to gain access to Google employees’ computer systems. This event has sparked the release of Microsoft Security Bulletin MS10-002 - Critical , and a public exploit for the vulnerability. To mitigate this vulnerability, Microsoft originally recommended that customers upgrade to Internet Explorer 8, and enable DEP (Data Execution Prevention). On January 21, 2010 Microsoft released an "out-of-band" patch for the vulnerability, which fixes the problem on Internet Explorer version 6, 7 and 8. Methods exist to reliably exploit Internet Explorer versions 6 & 7, and there are several people who have working exploits for IE version 8, including Dino Dai Zovi, a well-respected vulnerability researcher. (A concise list of the details surrounding this issue can be found in this article).
Many organizations are likely to implement the patch released by Microsoft since the issue has been receiving a lot of media attention. Patching because of a media event is an all-too-common mistake made by many organizations that cannot be convinced to implement new security measures until exploits make the news. Patching systems needs to be part of an organization’s overall strategy – not just a reaction to a media event. When new technologies become available as upgrades to your existing systems, put a plan in place to test and migrate to them, especially if they offer increased security. The organizations doing this today are looking at the latest exploit and implementing their patch strategy as part of the standard operating procedure.

Title: Google Considering Leaving China Date: January 12, 2010
In the wake of the attacks on Google and other companies, Google has indicated that it may no longer cooperate with Chinese censorship rules and that it may consider pulling out of China altogether. When Google opened operations in China in 2006, it operated under an agreement with the Chinese government that it would remove banned subject matter from search results.

Paired with this fascinating piece by Gerald Posner.
The ongoing story of the Chinese "cyberwar" just keeps popping up in the news, again and again, like a zombie that takes repeated blows with a shovel and just won't stop moving. Am I talking about it too much? Perhaps, but it's one of those nodal point issues that I think tells us an incredible amount about what's going on in information security at the government and major corporation level. What do I mean? It's becoming a litmus test, for me, as to who has a clue and who doesn't. But if you want to be a paranoid skeptic, ask yourself "why are people with clues acting as if they have none?"
