Privilege Escalation(N/A)

What is Privilege Escalation?

In one sentence: When regular user can do something to become admin and get access to everything!

Imagine you're in a company, you're a regular employee. You only have access to your own files. But you find a bug that you can make yourself admin! Now you have access to all files, all systems. This is Privilege Escalation.

Types:

Vertical: From regular user to admin. More dangerous.

Horizontal: From regular user to another regular user (like accessing others' accounts).

Common Methods:

• Exploiting system bugs
• Wrong sudo configuration
• Files with wrong permissions
• Credential Theft
• Token Manipulation

Why is it important for security?

Because if hacker can do Privilege Escalation, they have the whole system. Can steal all data, shut down all services, control everything.
