Defcon Quals challenge 2015 -- Twentyfiveseventy level WriteUp Not long ago, the Defcon Qualification ctf I attended was very interesting. I want to share with you the detail analysis of the longest level I used in this challenge. This level is "Twentyfiveseventy" in the PWNABLE directory. Generally, the level in this directory should be obtained through a vulnerability. Download this file [file can be do

Blackhat: Theory and Practice of WSUS vulnerability Exploitation Paul Stone and Alex Chapman proposed a Windows Server Update Service (WSUS) vulnerability in Blackhat2015. Attackers can exploit this vulnerability by using Man In The Middle (MITM) to allow users to download and install forged updates.As we all know, Microsoft provides users with updates through the Windows update service. The customer periodically runs wuauctl.exe to communicate with t

0X01 Research BackgroundAfter analyzing the source code of several bank Trojans exposed by Russians, it is found that most of them have a module that captures the user's personal information by hijacking the browser data packets, and obtains the plaintext data of the packets by intercepting the encrypted or decrypted packets in the browser memory. The Defcon 23 released tool Netripper This ability to have the above malicious bank Trojan, its open sour

In this Photoshop tutorial I will show you how to create a wood mosaic effect using wood textures, layer masks, and some creative selection techniques. Effect chart Step 1 First let's build a new document, and mine is 540x300 pixel, 72ppi. Size is not important. On the internet can find a lot of good wood texture, I use the texture on the defcon–x.de. We will first create 3 layers and paste each wood texture separately. Color is not imp

Opencv provides a common morphological function cvmorphologyex, which can be used to perform on-demand operations, close operations, form gradients, gift hat operations, and black hat operations. The example is as follows: # Include "stdafx. H "# include" CV. H "# include" highgui. H "# include" highgui. H "int main (INT argc, char ** argv) {cvnamedwindow (" sourceimage "); cvnamedwindow (" open "); cvnamedwindow (" close "); cvnamedwindow ("gradient"); cvnamedwindow ("tophat"); cvnamedwindow (

Erode and dilate are basic morphological operations, and we can compose more morphological operations based on these two operations.First, open Operation Openning DST = open (src, Element) = dilate (Erode (src, Element)) Open operation is to the image of the first corrosion and re-expansion, the main role is to remove the small white area. Second, closed Operation Closing DST = Close (src, Element) = Erode (dilate (src, Element)) Closed operation is to expand an im
