There are hundreds of easy to use tools that may be used to get IP addresses of the remote system. These tools are also used to scan the various IP ports to see if any port can be used to enter the target system. Adware, Spyware, worms and Trojan horses have been deployed into target systems using these tools. These then generate greater vulnerabilities so that the other tools the hacker has could be used to other purposes. Wireless devices have not been spared either. Most other smart hackers use disassemblers, scripting engines and input generators to find out more about a software or application. They find bugs in the give software and use these loop holes to gain access to systems where ever the software is installed. A few tools are DeCSS, Cold life, Intelli Tamper, John the ripper, and Nmap for Windows.
