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 VIA/Zhaoxin PadLock instructions are instructions designed to apply cryptographic primitives in bulk, similar to the 8086 repeated string instructions. As such, unless otherwise specified, they take, as applicable, pointers to source data in ES:rSI and destination data in ES:rDI, and a data-size or count in rCX.
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.
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.
It allowed the user name, domain name, and password hashes cached in memory by the Local Security Authority to be changed at runtime after a user was authenticated — this made it possible to 'pass the hash' using standard Windows applications, and thereby to undermine fundamental authentication mechanisms built into the operating system.
The part of the source code of an exploit that implements this technique is called a heap spray. [1] In general, code that sprays the heap attempts to put a certain sequence of bytes at a predetermined location in the memory of a target process by having it allocate (large) blocks on the process's heap and fill the bytes in these blocks with ...
EternalBlue [5] is a computer exploit software developed by the U.S. National Security Agency (NSA). [6] It is based on a vulnerability in Microsoft Windows that allowed users to gain access to any number of computers connected to a network.
With no process to terminate they are harder to detect and remove, which is a combination of both spyware and a rootkit. Rootkit technology is also seeing increasing use, [ 12 ] as newer spyware programs also have specific countermeasures against well known anti-malware products and may prevent them from running or being installed, or even ...
