Ethical Hacking System Hacking 2

Question 1

What is the primary function of a software keylogger in system hacking?

Accepted Answer

Recording all keystrokes entered on a compromised system to capture sensitive data

Answer

Keyloggers capture and record every keystroke on a system, allowing attackers to steal passwords, credit card numbers, messages, and other sensitive input.

Question 2

Which Windows subsystem service stores user credentials in memory to support single sign-on and is a primary target for credential dumping tools like Mimikatz?

Accepted Answer

LSASS (Local Security Authority Subsystem Service)

Answer

LSASS stores credentials in memory to facilitate Windows authentication; Mimikatz and similar tools target this process to extract plaintext passwords and hashes.

Question 3

What is lateral movement in the context of post-exploitation system hacking?

Accepted Answer

Using compromised credentials or exploits to spread access to other systems within the same network

Answer

Lateral movement involves leveraging compromised credentials, pass-the-hash, or exploits to extend access from one machine to other systems within the target network.

Question 4

Which technique involves loading a malicious DLL into the address space of a legitimate running process to execute attacker-controlled code?

Accepted Answer

DLL Injection

Answer

DLL injection loads a malicious dynamic-link library into the memory space of a legitimate process, executing attacker code under the cover of a trusted application.

Question 5

What is the primary purpose of establishing a backdoor on a compromised system?

Accepted Answer

To maintain persistent remote access even after system reboots or credential changes

Answer

Backdoors provide persistent, covert remote access to a compromised system even if the initial vulnerability is patched or user passwords are changed.
