The program relays all of the SMB traffic, excluding negotiation and authentication. As long as the target host remains connected, the user can disconnect from and reconnect to this virtual IP . SMBRelay collects the NTLM password hashes and writes them to hashes.txt in a format usable by L0phtCrack for cracking at a later time.
The list below explicitly refers to "SMB" as including an SMB client or an SMB server, plus the various protocols that extend SMB, such as the Network Neighborhood suite of protocols and the NT Domains suite. Microsoft Windows includes an SMB client and server in all members of the Windows NT family and in Windows 95, Windows 98, and Windows Me.
The System Management Bus (SMBus or SMB) is a single-ended simple two-wire bus for the purpose of lightweight communication. Most commonly it is found in chipsets of computer motherboards for communication with the power source for ON/OFF instructions. The exact functionality and hardware interfaces vary with vendors.
The pass the hash technique was originally published by Paul Ashton in 1997 [6] and consisted of a modified Samba SMB client that accepted user password hashes instead of cleartext passwords. Later versions of Samba and other third-party implementations of the SMB and NTLM protocols also included the functionality.
These instructions were introduced in the Cyrix 6x86MX and MII processors, and were also present in the MediaGXm and Geode GX1 [53] processors. (In later non-Cyrix processors, all of their opcodes have been used for SSE or SSE2 instructions.) These instructions are integer SIMD instructions acting on 64-bit vectors in MMX registers or memory.
One of the modes John can use is the dictionary attack. [6] It takes text string samples (usually from a file, called a wordlist, containing words found in a dictionary or real passwords cracked before), encrypting it in the same format as the password being examined (including both the encryption algorithm and key), and comparing the output to the encrypted string.
Samba is a free software re-implementation of the SMB networking protocol, and was originally developed by Andrew Tridgell.Samba provides file and print services for various Microsoft Windows clients [5] and can integrate with a Microsoft Windows Server domain, either as a Domain Controller (DC) or as a domain member.
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.
