Understanding Malware Injection

The video explains how software operates within a computer's memory and how malware can infiltrate this space. It discusses various processes and components like dynamic link libraries (DLLs) that run in memory. The video highlights malware injection techniques, focusing on DLL injection, where malicious code is inserted into a running process to gain higher privileges and avoid detection. The process involves placing a malicious DLL on a storage drive and linking it to a target process, allowing the malware to execute with the same permissions as the host process.

What is required for software to execute on a computer?

• It must be loaded from disk and run inside memory.

• It must be directly executed from the disk.

• It must be stored in the CPU.

• It must be connected to the internet.

Which of the following is NOT a component found in memory?

• Dynamic Link Libraries (DLLs)

• Threads

• Buffers

• Hard Drives

How can malware operate on a computer?

• Both A and B

• By running as its own process in memory

• By injecting itself into an existing process

• By directly modifying the CPU

What is the purpose of injecting malware into an existing process?

• Both A and B

• To directly access the CPU

• To gain the same rights and permissions as the target process

• To avoid detection by anti-malware software

What does DLL stand for?

• Dynamic Link Library

• Direct Link Library

• Dynamic Load Library

• Direct Load Library

What is the first step attackers take to perform DLL injection?

• Disable the anti-malware software

• Directly modify the CPU

• Install the malicious DLL onto some storage accessible by the system

• Change the system's memory management functions

Why is DLL injection a common method for malware?

• It allows malware to avoid detection and gain higher permissions

• It does not require any storage space

• It is the only method available

• It is the fastest method

What does the attacker need to do after placing the malicious DLL on the storage drive?

• Disable the system's memory management functions

• Modify the CPU settings

• Directly execute the DLL

• Put a path to the DLL inside the target process

What happens when the target process reaches the point where it needs to reference the DLL?

• It pulls in the malicious DLL and loads it into memory

• It stops executing

• It crashes

• It sends an alert to the user

What is the final outcome of a successful DLL injection?

• The malware runs on the system

• The system shuts down

• The CPU is modified

• The memory is cleared
