When developers are doing programming or decompilers are doing decryption, they may need to perform DLL injection to test the security or stability of the program. The so-called DLL injection is to put a DLL into the address space of a running process, making it a part of that process and loading them together. If you are looking for an easy-to-use and efficient DLL injection tool, try DLL Injector Hacker.

LOIC (short for Low Orbit Ion Cannon) is a free and open-source network/website stress testing tool initially developed by Praetox Technologies (currently maintained by the open source community) with C# in 2014.

The god knows who is using L0phtCrack as a security auditing tool to do the so-called password strength testing or recovery.
