Use js for value assignment to restore JavaScript obfuscated code

Method 1: Use the IE Developer tool (IE 8 has already come with it, and IE Developer Toolbar needs to be downloaded and installed before IE7) for anti-obfuscation. I often use Chrome, but there is no way to use Chrome's built-in developer tools to implement anti-obfuscation... I hope you will be informed of this...

Don't worry, directly

Method 2: code implementation (ps. well, as a common resentment among some developers, many developers want to use their own developed things most often, so they can't wait for the OS to go on their own, when I implemented it myself, I implemented method 2 first, and then I used IE again... -_-|)

First paste a obfuscated test code

Eval (function (p, a, c, k, e, d) {e = function (c) {return (c)

Implementation: www.2cto.com

1.create a new webpage xxx.html

2. Add a div container id = "divTest"

3. the most critical step is to execute the Value assignment: (in the obfuscated code above, extract the content in eval () and assign a value (or print it directly) to the document. getElementById ('divtest '). innerText)

Document. getElementById ('divtest'). innerText = function (p, a, c, k, e, d) {e = function (c) {return (c)

Open xxx.html to display the result: (The unobfuscated code has been compressed, and other characters such as line breaks are removed)

Alert ("Gloomy reverse obfuscation Test 1"); function a () {alert ("Gloomy reverse obfuscation Test 2")} var B = function () {alert ("Gloomy reverse obfuscation Test 3")}; a (); B ()
