A popular approach to obfuscating malicious browser scripts involves using JavaScript itself to decode the original script when the browser processes the malicious web page. Malware analysts can often bypass such defensive measures by running the script in a standalone JavaScript engine to observe its execution or examine its output. Mozilla's SpiderMonkey has been a common choice for this task. Google's V8 engine is a powerful, though lesser-known alternative for accomplishing this.
Deobfuscating JavaScript Using SpiderMonkey
SpiderMonkey is a standalone JavaScript language that is used in Firefox. We can use SpiderMonkey to run the malicious script outside of the browser, letting it deobfuscate itself.At the end of the deobfuscation process, the malicious script often transfers control to the newly-decoded code using document.write() or eval() commands.
One way to spy on such commands is to compile a customized version of SpiderMonkey, as Didier Steven did when tackling this challenge. Another is to use JavaScript itself to definedocument.write()or redefineeval()commands like this:

document = {

eval = function(input_string) { }
You can safe these definitions into a separate file (e.g., file.js) and load it into SpiderMonkey before the file containing the malicious script (malware.js). SpiderMonkey (js) lets you do this from the command-line like this:

js -f file.js -f malware.js
In this case, SpiderMonkey will define the necessary objects and methods according to file.js contents, then execute the malicious script. The script will likely deobfuscate its protected components. If the script executesdocument.write()or redefineeval()at the end of this process, SpiderMonkey will show you the output, which should be the decoded contents.
SpiderMonkey runs best on a Unix platform. You can compile it from source code by following Mozilla's build instructions. On a Debian or Ubuntu platform you can install SpiderMonkey using the spidermonkey-bin this means that a malicious script might deobfuscate fine on Chrome (V8), but not on Firefox (SpiderMonkey). In particular, SpiderMonkey optimizes the results of the arguments.callee.toString() call, while V8 does not. There are other differences in the way V8 and SpiderMonkey are implemented as well.
To build V8 from source code on a Unix platform, follow Google's instructions. First, install the tools necessary to get and build V8. These include g++, SVN and scons, which are available as packages on Debian and Ubuntu platforms. Then download the source code using SVN:

svn checkout http://v8.googlecode.com/svn/trunk/ v8
Then build the tool, including its command-line interface shell called d8 using scons:

cd v8

scons d8
Though the tool is called V8, to use the d8 command to invoke it, just like you'd utilize the js command for SpiderMonkey:

d8 -f file.js -f malware.js
SpiderMonkey and V8 will be installed in the upcoming update to the REMnux Linux distribution. If this topic interests you, check out the Reverse-Engineering Malware course I'll be teaching at SANS on-line in January-February 2012.

Security assessment reviews an organization’s mobile security policies and technologies, evaluating the mobile security posture against a set of 15 core elements.

Symantec’s consulting team is launching a mobile security assessment service, designed to assess a business’ mobile security policies and defensive technologies.

The new service is an extension of the Symantec Security Program Assessment. Symantec created a Mobile Security Framework that is designed to evaluate how a business addresses mobile device security from a governance, intelligence and infrastructure perspective. Among the 15 core elements that make up the framework are policies, standards and awareness, asset inventory and ownership, application security and monitoring and reporting metrics.

Symantec’s mobile assessment service is one of many available to enterprises. Security vendors have been quick to offer a variety of mobile services and products because businesses have been inundated with employees bringing in personal devices that they expect to connect to the corporate network. For example, McAfee, Verizon Business, IBM and other firms provide a variety of consulting services that can evaluate security programs and more specifically, an organization’s mobile security posture. Experts have been touting ways to write effective mobile security policies to address the influx. Technologies are available to address policy enforcement across platforms and control access to sensitive data.

In an interview with SearchSecurity.com, Franklin Witter, manager of security business practices at Symantec, said his consulting team will use a series of surveys, workshops and interviews to understand the organization’s risk tolerance and practices and technologies already in place. “We want to understand the business use case for mobile technology in the enterprise,” Witter said.

The goal is to lay out a security plan that addresses the strengths and weaknesses inherent in each mobile platform, Witter said. Organizations will get a better understanding of the gaps in their current state of maturity.

Witter said Symantec clients that have undergone a full security program assessment have been asking for a more focused mobile evaluation. “Our advisory team takes a product agnostic approach,” Witter said. “We’re not solely focused on Symantec products.”

The Symantec Mobile Security Assessment Suite costs about $40,000. Organizations that undergo the review are given a final written report and scorecard illustrating the organization’s mobile security readiness. The report also provides recommendations and an action plan to address existing gaps.
Mobile Application Assessment Service

Symantec also rolled out an application assessment service designed to test mobile apps for a variety of coding errors that could lead to data leakage or a costly data breach. Witter said the testing will be offered in either a white-box or black-box testing. The cost of the evaluation will depend on the scope of the project, he said.

The application assessment service has been operating for about a year. Symantec is seeing an increase in businesses designing custom applications for either employee use or for their customers.

The assessment can identify issues with authentication and authorization, data validation, session management, encryption, auditing and logging and the business logic of a mobile application. It can be performed in conjunction with a penetration assessment to provide a more deeper view of vulnerabilities.
