Process Explorer

Ever wondered which program has a particular file or directory open? Now you can find out. Process Explorer shows you information about which handles and DLLs processes have opened or loaded. The Process Explorer display consists of two sub-windows. The top window always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that Process Explorer is in: if it is in handle mode you\'ll see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you\'ll see the DLLs and memory-mapped files that the process has loaded. Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded.

Process Hacker

Process Hacker is a tool for viewing and manipulating processes and their threads, modules, memory and handles, and viewing and editing services. It can also read/write process memory and search through process memory using literal bytes or regular expressions. It can view the command line and current directory of a process, view/edit its DEP status, and even DRM-protect and unprotect it. It can run programs as another user or as SYSTEM, LOCAL SERVICE or NETWORK SERVICE if you have administator privileges. This is achieved using a helper program which is installed as a system service (similar to PsExec). It loads symbols from various libraries automatically and uses them when displaying the call stacks of threads (just like Process Explorer). It also has a disassembler derived from OllyDbg's which can be accessed when viewing PE files' exports. It can bypass most kernel-mode hooks and user-mode hooks on ZwOpenProcess, ZwOpenThread and ZwOpenProcessToken.

Netcat

Netcat is a featured networking utility which reads and writes data across network connections, using the TCP/IP protocol. It is designed to be a reliable "back-end" tool that can be used directly or easily driven by other programs and scripts. At the same time, it is a feature-rich network debugging and exploration tool, since it can create almost any kind of connection you would need and has several interesting built-in capabilities. It provides access to the following main features: * Outbound and inbound connections, TCP or UDP, to or from any ports. * Featured tunneling mode which allows also special tunneling such as UDP to TCP, with the possibility of specifying all network parameters (source port/interface, listening port/interface, and the remote host allowed to connect to the tunnel. * Built-in port-scanning capabilities, with randomizer. * Advanced usage options, such as buffered send-mode (one line every N seconds), and hexdump (to stderr or to a specified file) of trasmitted and received data. * Optional RFC854 telnet codes parser and responder.

WebGoat

WebGoat is a deliberately insecure J2EE web application maintained by OWASP designed to teach web application security lessons. In each lesson, users must demonstrate their understanding of a security issue by exploiting a real vulnerability in the WebGoat application. For example, in one of the lessons the user must use SQL injection to steal fake credit card numbers. The application is a realistic teaching environment, providing users with hints and code to further explain the lesson.
