Version 1.0 (freeware) allowed users to login into Linux based operating systems and to bypass the authentication process (allowing access to the system without knowing the password). In 2009 author of this software announced Kon-Boot for Linux and 32-bit Microsoft Windows systems. [ 7 ]
Unlocking the bootloader allows installing and running unsigned code on a device, including user customized software. Operating outside the manufacturer specification might usually result in voiding any warranties and may make the device susceptible to data theft, as the integrity of the operating system (as intended by the manufacturer) can no longer be guaranteed.

chntpw has no support for fully encrypted NTFS partitions (the only possible exceptions to this are encrypted partitions readable by Linux such as LUKS), usernames containing Unicode characters, or Active Directory passwords (with the exception of local users of systems that are members of an AD domain). The password changing feature is also ...
Hydra (or THC Hydra) is a parallelized network login cracker built into various operating systems like Kali Linux, Parrot and other major penetration testing environments. [2] It was created as a proof of concept tool, for security researchers to demonstrate how easy it can be to crack logins.
Kali Linux is a Linux distribution designed for digital forensics and penetration testing. [4] It is maintained and funded by Offensive Security . [ 5 ] The software is based on the Debian Testing branch: most packages Kali uses are imported from the Debian repositories . [ 6 ]
Ophcrack is a free open-source (GPL licensed) program that cracks Windows log-in passwords by using LM hashes through rainbow tables.The program includes the ability to import the hashes from a variety of formats, including dumping directly from the SAM files of Windows, and can be run via the command line or using the program’s GUI (Graphical user interface).
The purpose of password cracking might be to help a user recover a forgotten password (due to the fact that installing an entirely new password would involve System Administration privileges), to gain unauthorized access to a system, or to act as a preventive measure whereby system administrators check for easily crackable passwords. On a file ...
The attack exploits an implementation weakness in the authentication protocol, where password hashes remain static from session to session until the password is next changed. This technique can be performed against any server or service accepting LM or NTLM authentication, whether it runs on a machine with Windows, Unix, or any other operating ...
