You can leech free wifi from some paid hotspots by monkeying around with the URLs. Most paid wifi hotspots accept your browser’s request and then redirect you to a login page where you need to pay to access the network. But some systems of this nature are set up in such a way that images and other direct file requests seem to slip through without the redirect to the login page. It’s essentially an oversight on the network administrator’s part, so it may not work with every hotspot. But here’s the hack: just append ?.jpg to the end of your queries to trick the network into loading the full webpage for free. The browser passes this info along as an extra parameter and the site in question will likely just ignore it, loading the page as normal. Of course this tip comes from a blog post that’s nearly two years old, so there’s no guarantees. But here’s the basic code, which I pulled from a commenter on Lifehacker’s write up:
if (window.location.toString().match(".jpg") == null) { window.location.replace(window.location + '?.jpg'); }
Save that as JavaScript file and add it to Firefox via Greasemonkey and give it a shot. Of course since there are plenty of free networks in most places, there isn’t much point to hacking paid networks. But for situations like airports, hotels and other isolated, expensive networks, it could come in handy. [click to continue…]
WEPCrack is a tool that cracks 802.11 WEP encryption keys using the latest discovered weakness of RC4 key scheduling.
Tool Capabilities :
The current tools are Perl based, and are composed of the following scripts:
1) WeakIVGen.pl – This script allows a simple emulation of IV/encrypted output that one might observe with a WEP enable 802.11 Access Point. The script generates IV combinations that can weaken the secret key used to encrypt the WEP traffic
2) prism-getIV.pl – This script relies on output from Prismdump [or from Ethereal captures if libpcap has been patched for 802.11 monitor
mode], and looks for IVs that match the pattern known to weakned secret keys. This script also captures the 1st byte of the encrypted output and places it and the weak IVs in a logfile.
3) WEPCrack.pl – This script uses data collected or generated by WeakIVGen to attempt to determine the secret key. It will work with either 40bit or 128bit WEP.
Additionaly, a script prism-decode.pl is included that will decode most 802.11 frame types. This tool is intended to be used with prismdump, but could also be used against Ethereal 802.11 saved captures. It might be useful for capturing SSIDs, AP MAC addresses, or authentication data.
Coders Arena is an Online Programming Contest held at Technovation.
Computer programming (often shortened to programming or coding) is the process of writing, testing, debugging/troubleshooting, and maintaining the source code of computer programs. This source code is written in a programming language. The code may be a modification of an existing source or something completely new. The purpose of programming is to create a program that exhibits a certain desired behavior (customization). The process of writing source code requires expertise in many different subjects, including knowledge of the application domain, specialized algorithms and formal logic.
