A loader or injector is a type of malware component designed to load, insert, or execute additional malicious code within a target system’s memory. These tools are often used by attackers to deploy secondary payloads, such as ransomware, spyware, or remote access trojans, without leaving obvious traces on disk. Loaders and injectors typically exploit system vulnerabilities or use process injection techniques to bypass security controls. Their primary goal is to establish persistence, evade detection, and facilitate the execution of further malicious activities on the compromised system.
