[How to] Use Windows 7 to create a Wi-Fi network without using router
Posted by Shivam Gupta
If you have got Wi-Fi in your laptop and have Windows 7 installed in it then you can easily turn it into a Wi-Fi hotspot and share your net connection with other people in the range andVirtual Router is the easiest way to do so.
Virtual Router is an open source software which leverages the Wireless Hosted Network API which is a part of the new Windows Operating Systems (Windows 7 and Windows server 2008).
With this feature, a Windows computer can use a single physical wireless adapter to connect as a client to a hardware access point (AP), while at the same time acting as a software AP allowing other wireless-capable devices to connect to it. This feature requires that a Hosted Network capable wireless adapter is installed in the local computer. (quoted from MS library)
The program is really simple to use. After downloading and installing the software all you have to do is specify the network name and password to access this network. It uses the WPA-2encryption to protect the wireless network from unwanted users.
The program requires only 20mb of RAM and is pretty simple to understand and use. Requires Windows 7 or Windows server 2008 to run.

Posted by Shivam gupta
Even after the virus is totally removed from the system, some users find it difficult to restore all those things back which were affected by the virus. A virus usually when enters into a system disables the registry editor and task manager so that the user can not remove the virus from the system.
Here is a free tool Re-Enable using which even a novice users can fix all the things which were disabled by the virus. An antivirus can remove the virus files but sometimes it may fail to restore the system settings. In such situations this tool can come handy.
First download Re-Enable 2.0 from here. After downloading the file execute it. As you can see in the screenshot, this tool can be used to re-enable registry editor, command prompt, task manager, folder options etc. Just select the tools you want to enable and click on the “Re-Enable” button.

Top 15 Security/Hacking Tools and Utilities
1. Nmap
I think everyone has heard of this one, recently evolved into the 4.x series.
Nmap (“Network Mapper”) is a free open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. Nmap runs on most types of computers and both console and graphical versions are available. Nmap is free and open source.
Can be used by beginners (-sT) or by pros alike (–packet_trace). A very versatile tool, once you fully understand the results.
2. Nessus Remote Security Scanner
Recently went closed source, but is still essentially free. Works with a client-server framework.
Nessus is the world’s most popular vulnerability scanner used in over 75,000 organizations world-wide. Many of the world’s largest organizations are realizing significant cost savings by using Nessus to audit business-critical enterprise devices and applications.
3. John the Ripper
John the Ripper is a fast password cracker, currently available for many flavors of Unix (11 are officially supported, not counting different architectures), DOS, Win32, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords. Besides several crypt(3) password hash types most commonly found on various Unix flavors, supported out of the box are Kerberos AFS and Windows NT/2000/XP/2003 LM hashes, plus several more with contributed patches.
4. Nikto
Nikto is an Open Source (GPL) web server scanner which performs comprehensive tests against web servers for multiple items, including over 3200 potentially dangerous files/CGIs, versions on over 625 servers, and version specific problems on over 230 servers. Scan items and plugins are frequently updated and can be automatically updated (if desired).
Nikto is a good CGI scanner, there are some other tools that go well with Nikto (focus on http fingerprinting or Google hacking/info gathering etc, another article for just those).
5. SuperScan
Powerful TCP port scanner, pinger, resolver. SuperScan 4 is an update of the highly popular Windows port scanning tool, SuperScan.
If you need an alternative for nmap on Windows with a decent interface, I suggest you check this out, it’s pretty nice.
6. p0f
P0f v2 is a versatile passive OS fingerprinting tool. P0f can identify the operating system on:
– machines that connect to your box (SYN mode),
– machines you connect to (SYN+ACK mode),
– machine you cannot connect to (RST+ mode),
– machines whose communications you can observe.
– machines you connect to (SYN+ACK mode),
– machine you cannot connect to (RST+ mode),
– machines whose communications you can observe.
Basically it can fingerprint anything, just by listening, it doesn’t make ANY active connections to the target machine.
7. Wireshark (Formely Ethereal)
Wireshark is a GTK+-based network protocol analyzer, or sniffer, that lets you capture and interactively browse the contents of network frames. The goal of the project is to create a commercial-quality analyzer for Unix and to give Wireshark features that are missing from closed-source sniffers.
Works great on both Linux and Windows (with a GUI), easy to use and can reconstruct TCP/IP Streams! Will do a tutorial on Wireshark later.
8. Yersinia
Yersinia is a network tool designed to take advantage of some weakeness in different Layer 2 protocols. It pretends to be a solid framework for analyzing and testing the deployed networks and systems. Currently, the following network protocols are implemented: Spanning Tree Protocol (STP), Cisco Discovery Protocol (CDP), Dynamic Trunking Protocol (DTP), Dynamic Host Configuration Protocol (DHCP), Hot Standby Router Protocol (HSRP), IEEE 802.1q, Inter-Switch Link Protocol (ISL), VLAN Trunking Protocol (VTP).
The best Layer 2 kit there is.
9. Eraser
Eraser is an advanced security tool (for Windows), which allows you to completely remove sensitive data from your hard drive by overwriting it several times with carefully selected patterns. Works with Windows 95, 98, ME, NT, 2000, XP and DOS. Eraser is Free software and its source code is released under GNU General Public License.
An excellent tool for keeping your data really safe, if you’ve deleted it..make sure it’s really gone, you don’t want it hanging around to bite you in the ass.
10. PuTTY
PuTTY is a free implementation of Telnet and SSH for Win32 and Unix platforms, along with an xterm terminal emulator. A must have for any h4x0r wanting to telnet or SSH from Windows without having to use the crappy default MS command line clients.
11. LCP
Main purpose of LCP program is user account passwords auditing and recovery in Windows NT/2000/XP/2003. Accounts information import, Passwords recovery, Brute force session distribution, Hashes computing.
A good free alternative to L0phtcrack.
LCP was briefly mentioned in our well read Rainbow Tables and RainbowCrack article.
12. Cain and Abel
My personal favourite for password cracking of any kind.
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, 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.
13. Kismet
Kismet is an 802.11 layer2 wireless network detector, sniffer, and intrusion detection system. Kismet will work with any wireless card which supports raw monitoring (rfmon) mode, and can sniff 802.11b, 802.11a, and 802.11g traffic.
A good wireless tool as long as your card supports rfmon (look for an orinocco gold).
14. NetStumbler
Yes a decent wireless tool for Windows! Sadly not as powerful as it’s Linux counterparts, but it’s easy to use and has a nice interface, good for the basics of war-driving.
NetStumbler is a tool for Windows that allows you to detect Wireless Local Area Networks (WLANs) using 802.11b, 802.11a and 802.11g. It has many uses:
- Verify that your network is set up the way you intended.
- Find locations with poor coverage in your WLAN.
- Detect other networks that may be causing interference on your network.
- Detect unauthorized “rogue” access points in your workplace.
- Help aim directional antennas for long-haul WLAN links.
- Use it recreationally for WarDriving.
15. hping
To finish off, something a little more advanced if you want to test your TCP/IP packet monkey skills.
hping is a command-line oriented TCP/IP packet assembler/analyzer. The interface is inspired to the ping unix command, but hping isn’t only able to send ICMP echo requests. It supports TCP, UDP, ICMP and RAW-IP protocols, has a traceroute mode, the ability to send files between a covered channel, and many other features.
