Geometric significance of feature vectors
For a long time, I have never understood the significance of the matrix feature values and feature vectors (it is estimated that many of them feel the same way ). I know its mathematical formula, but I can't find its geometric meaning. in textbooks, I didn't really instantiate this concept from various perspectives to explain it, it's just a day or night.According
XSS Posture--File upload XSSOriginal link: http://brutelogic.com.br/blog/0x01 Brief Introduction
A file upload point is a great opportunity to execute an XSS application. Many sites have user rights to upload a profile picture of the upload point, you have many opportunities to find the relevant loopholes. If it happens to be a self XSS, you can look at thi

From a Flash XSS on Sina Weibo to XSS Worm
I have been studying some flash files recently, hoping to find something.
By accident, a swf: http://vgirl.weibo.com/swf/BlogUp.swf (repaired), which is generally known as XSS, which is the flash of the upload.
Decompilation:

XSS attack principle and how PHP can prevent XSS attacks
XSS, also known as CSS, is short for Cross-site scripting (XSS) attacks. XSS attacks are similar to SQL injection attacks and are common vulnerabilities in Web programs. XSS

Most people have a basic understanding of the principles of XSS. Here we will not repeat it again. We will only provide a complete example to demonstrate its principles.1. Role Assignment

Previous: http://www.bkjia.com/Article/201209/153264.htmlThe stored xss vulnerability means that the data submitted by user A is stored in A web program (usually in A database) and then displayed directly to other users. In this way, if the data contains malicious code, it will be executed directly in the user's browser.Such vulnerabilities may exist on the Q A platform or personal information settings.

I believe everyone has had this experience when conducting penetration tests. It is clear that there is an XSS vulnerability, but there are XSS filtering rules or WAF protection, which makes us unable to use it successfully, for example, if we enter

The simplest thing is to change the case sensitivity.
During the test, we can change the case sensitivity of the test statement to bypass the XSS rules.
For example, can be converted:
0 × 002
You can also disable the label.
Sometimes we need to close the tag to make our XSS take effect, such:

Use HEX Encoding to bypass
We can encode our statements to bypass the

Introduction:
In the above example, we have studied XSS attacks from the inside, by conveying a piece of harmful js Code to the victim's machine, let it run this harmful JS code on the victim's domain for intrusion purposes. Now let's take a look at external XSS attacks.
Practice:
In the following example, I will explain what XSS attacks come from outside in pla

Can not use large MATLAB is also a kind of liberation, the default use of Freemat, no time to consider other alternatives. When it comes to computing, try to implement DirectX and Irrlicht two versions, also refer to some source code. (mainly used to see the implementation of the formula in C + +) Basically, I w
As we all know, the common method to defend against XSS attacks is to escape the following characters in the background: First, let's look at a JS example: run this code and the result is as follows:Do you feel excited when you see such familiar angle brackets? No angle brackets appear in JS Code, but the angle brackets are output during runtime !!! This means that \ u003c and \ u003e can be used instead of Test run the preceding code and the result i

We know that matrix multiplication corresponds to a transformation, which converts any vector into a new vector with different directions or lengths. During this transformation, the original vector mainly changes in rotation and scaling. If a matrix only performs scaling transformation on a vector or some vectors and does not rotate these vectors, these vectors a
