How to hide files in JPEG pictures If you’re looking to hide files on your PC hard drive, you may have read about ways to encrypt folders or change the attributes on a file so that they cannot be accessed by prying eyes. However, a lot of times hiding files or folders in that way requires that you install some sort of software on your computer, which could then be spotted by someone else. I’ve actually written quite a few articles on how you can hide files and folders in Windows XP and Vista before, but here I’m going to show you a new way to hide files that is very counter-intuitive and therefore pretty safe! Using a simple trick in Windows, you can actually hide a file inside of the JPG picture file! You can actually hide any type of file inside of an image file, including txt, exe, mp3, avi, or whatever else. Hide File in Picture In order to accomplish this task, you will need to have either WinZip or WinRAR installed on your computer. Create a folder on your hard drive, i.e. Now here’s the fun part! And that’s it!
remore exploit Back¦Track-fr sécurité réseau & intrusion Cain & Abel Cain & Abel is a password recovery tool for Microsoft Operating Systems. It allows easy recovery of various kind of passwords by sniffing the network, cracking encrypted passwords using Dictionary, Brute-Force and Cryptanalysis attacks, recording VoIP conversations, decoding scrambled passwords, recovering wireless network keys, revealing password boxes, uncovering cached passwords and analyzing routing protocols. The program does not exploit any software vulnerabilities or bugs that could not be fixed with little effort. It covers some security aspects/weakness present in protocol's standards, authentication methods and caching mechanisms; its main purpose is the simplified recovery of passwords and credentials from various sources, however it also ships some "non standard" utilities for Microsoft Windows users. The latest version is faster and contains a lot of new features like APR (Arp Poison Routing) which enables sniffing on switched LANs and Man-in-the-Middle attacks.

This research presents a new debugger named Virt-ICE, which is designed to address the problems of current malware debuggers. We conclude the talk with some live demos to show how Virt-ICE can debug some real malware.

Tutorial: Cracking WEP Using Backtrack 3 | What's the w0rd? Standard Disclaimer: This article is provided for informational purposes only. thew0rd.com and its affiliates accept no liability for providing this information. Please only use to test configurations on your own equipment. Accessing WIFI networks that do not belong to you is ILLEGAL. This article will explan how to crack 64bit and 128bit WEP on many WIFI access points and routers using Backtrack, a live linux distribution. Requirements: I will assume that you have downloaded and booted into Backtrack 3. Preparing The WIFI Card First we must enable “Monitor Mode” on the wifi card. modprobe -r iwl3945 modprobe ipwraw The above commands will enable monitor mode on the wireless chipset in your computer. iwconfig Take note of your wireless adapter’s interface name. airmon-ng stop [device] Then: ifconfig down [interface] Now we must change the MAC address of the adapter: macchanger --mac 00:11:22:33:44:66 [device] Its now time to start the card in monitor mode by doing: airmon-ng start [device]
In Unix, how do I change the permissions for a file You can change file permissions with the chmod command. In Unix, file permissions, which establish who may have different types of access to a file, are specified by both access classes and access types. Access classes are groups of users, and each may be assigned specific access types. There are two basic ways of using chmod to change file permissions: Symbolic method The first and probably easiest way is the relative (or symbolic) method, which lets you specify access classes and types with single letter abbreviations. For example, to add permission for everyone to read a file in the current directory named myfile, at the Unix prompt, you would enter: chmod a+r myfile The a stands for "all", the + for "add", and the r for "read". Note: This assumes that everyone already has access to the directory where myfile is located and its parent directories; that is, you must set the directory permissions separately. chmod +r myfile chmod go-rw myfile chmod a-w+x myfile chmod go=r myfile chmod o-w mydir
Firesheep - codebutler When logging into a website you usually start by submitting your username and password. The server then checks to see if an account matching this information exists and if so, replies back to you with a "cookie" which is used by your browser for all subsequent requests. It's extremely common for websites to protect your password by encrypting the initial login, but surprisingly uncommon for websites to encrypt everything else. This is a widely known problem that has been talked about to death, yet very popular websites continue to fail at protecting their users. Today at Toorcon 12 I announced the release of Firesheep, a Firefox extension designed to demonstrate just how serious this problem is. After installing the extension you'll see a new sidebar. As soon as anyone on the network visits an insecure website known to Firesheep, their name and photo will be displayed: Double-click on someone, and you're instantly logged in as them. That's it.
