1. Linux Hacking

Definition: Linux Hacking involves exploiting vulnerabilities in the Linux operating system to gain unauthorized access or escalate privileges. Given its open-source nature and widespread use in servers, Linux systems can be targets for ethical hackers seeking to assess and enhance security.

Common Linux Hacking Techniques:
Examples and Real-Life Use Cases:
Ethical Considerations:

Linux hacking techniques should only be used in authorized penetration tests and security assessments. Unauthorized access or exploitation of vulnerabilities is illegal and unethical.

2. Trojans & Backdoors

1. Trojans

Definition: Trojans disguise themselves as legitimate software to trick users into installing them. Once installed, they perform malicious activities, such as stealing information or creating a backdoor for further attacks.

2. Backdoors

Definition: Backdoors are hidden methods of bypassing normal authentication to gain unauthorized access to a system, often installed by attackers after an initial compromise.

Ethical Considerations:

Understanding and dealing with Trojans and backdoors requires responsible action within legal boundaries and with proper authorization.

3. Virus & Worms

1. Viruses

Definition: Viruses attach themselves to legitimate programs or files and spread when those programs are executed. They can corrupt or delete data and affect system performance.

2. Worms

Definition: Worms are standalone malware that replicate and spread across networks without requiring a host file or program.

Ethical Considerations:

Ethical hackers must ensure their work is within legal boundaries and conducted with proper authorization to prevent malware infections.

Summary

1. Linux Hacking

Definition: Linux Hacking involves exploiting vulnerabilities in Linux systems to gain unauthorized access or escalate privileges. Given Linux's widespread use in servers, it is a key target for security assessments.

Common Linux Hacking Techniques:
Ethical Considerations:

Linux hacking techniques must be conducted within authorized penetration tests and security assessments.

2. Trojans & Backdoors

1. Trojans

Definition: Trojans disguise as legitimate software but perform malicious activities once installed.

2. Backdoors

Definition: Backdoors are methods that allow attackers to bypass authentication and gain unauthorized access.

Ethical Considerations:

Dealing with Trojans and backdoors must be within legal and authorized environments.

3. Virus & Worms

1. Viruses

Definition: Viruses attach to legitimate programs and spread when executed, potentially corrupting data and affecting performance.

2. Worms

Definition: Worms are standalone malware that replicate across networks without needing a host file.

Ethical Considerations:

Ethical hackers must ensure all actions are authorized and prevent malware from spreading.
