In cryptanalysis and computer security, password cracking is the process of guessing passwords [1] protecting a computer system. A common approach ( brute-force attack ) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. [ 2 ]
One solution is a "shadow" password file to hold the password hashes separate from the other data in the world-readable passwd file. For local files, this is usually /etc/shadow on Linux and Unix systems, or /etc/master.passwd on BSD systems; each is readable only by root. (Root access to the data is considered acceptable since on systems with ...
Rootkit installation can be automated, or an attacker can install it after having obtained root or administrator access. [3] Obtaining this access is a result of direct attack on a system, i.e. exploiting a vulnerability (such as privilege escalation) or a password (obtained by cracking or social engineering tactics like "phishing"). Once ...
The FAQ section of the TrueCrypt website states that the Trusted Platform Module (TPM) cannot be relied upon for security, because if the attacker has physical or administrative access to the computer and you use it afterwards, the computer could have been modified by the attacker e.g. a malicious component—such as a hardware keystroke logger ...
The arrow represents a rootkit gaining access to the kernel, and the little gate represents normal privilege elevation, where the user has to enter an Administrator username and password. Privilege escalation is the act of exploiting a bug , a design flaw , or a configuration oversight in an operating system or software application to gain ...
User name okay, password needed. 332: No need account for login. 334: Server accepts the security mechanism specified by the client; some security data needs to be exchanged. 336: Username okay, password okay. Challenge is "....". 421: Service available, closing control connection. This may be a reply to any command if the service knows it must ...
