Circumventing Automated JavaScript Analysis Tools
Billy Hoffman

[snip]

Next we explore multiple new techniques to circumvent the current generation of automated analysis tools by detecting their presence from inside malicious JavaScript. (JSPill? hmmmm) These methods include HTTP/browser fingerprinting, DOM testing and encrypting, Doman and Network testing, Execution environment testing, and cross plugin communication testing. We will demonstrate malicious JavaScript detecting analysis tools using these methods and refusing to give up its secrets until its running in the web browser of choice. We’ll demonstrate encrypting JavaScript to only run in particular browsers or environments. We’ll also demonstrate a couple other tricks, such as encoding malicious JavaScript as nothing but white space, and function clobbering for fun and profit.

Time to kick CaffineMonkey in the ass. Sorry Ben, I owe you a beer.

And, as is often the case, this technology has no legitimate use.
