Black Hat Asia 2014: The Weaponized WebThese Black Hat Briefings explore ways the Web can be weaponized -- and how to defend against them
The World Wide Web has grown exponentially since its birth 21 years ago, and it now serves as the interface for many of the apps we use every day. It's hard to imagine a more enticing target for hacks and exploits. Today's trio of Black Hat Briefings explore ways the Web can be weaponized ... and how to defend against it.
Even as HTML 5 proliferates as an enabler of rich interactive Web applications, cross-site scripting (XSS) remains one of the top three Web application vulnerabilities. DOM-based XSS is growing in popularity, but its client-side nature makes it difficult to monitor for malicious payloads. Ultimate Dom Based XSS Detection Scanner on Clouddelves into this thorny issue. Nera W. C. Liu and Albert Yu will show how they managed to introduce and propagate tainted attributes to a DOM input interface, and then devised a system to detect such breaches by harnessing the power of PhantomJS, a headless browser for automation.
Ready-made exploit kits make it easier than ever for malicious parties to victimize unwary Internet users. Jose Miguel Esparza will take us down that rabbit hole in PDF Attack: A Journey From the Exploit Kit to the Shellcode, in which he'll teach how to manually extract obfuscated URLs and binaries from these weaponized pages. You'll also learn how to do modify a malicious PDF payload yourself to bypass AV software, a useful trick for pentesting.
