What is pwdump?

pwdump is the name of various Windows programs that output the LM and NTLM password hashes of local user accounts from the Security Account Manager (SAM). In order to work, it must be run under an Administrator account, or be able to access an Administrator account on the computer where the hashes are to be dumped. Pwdump could be said to compromise security because it could allow a malicious administrator to access user's passwords. Most of these programs are open-source.
