Which of the following is a technique used for code injection in software?

DLL Sideloading is a technique used for code injection in software, primarily involving the loading of a malicious Dynamic Link Library (DLL) in a manner that is exploited by an application. This technique takes advantage of the way Windows handles DLLs, where the operating system searches for the required DLLs in specific directories. If the DLL is embedded with malicious code and is named the same as a legitimate DLL, the application may unknowingly load the malicious version, executing the injected code.

This method is particularly effective because it can bypass security measures that are designed to check for malicious activity, especially if the compromised DLL is placed in a trusted location. Often, attackers will deploy this method by creating a fake version of a legitimate application that is expected to call a specific DLL, thereby injecting their own code and establishing control over the executed application.

The other options relate to security concepts but don't specifically reference code injection techniques. Payload embedding refers to the insertion of a payload into a program but doesn’t necessarily imply code execution like DLL sideloading does. Fileless execution involves running code in memory without writing files to disk, which can be a lead to code execution but is distinct from traditional code injection methods.
