Quotprocess injection12/5/2023 ![]() ![]() There are some cases in which we won’t do this, and we can instead just hijack an existing thread. In our case, we want to create a new thread within a process that will run our code. When we talk about processes within Windows, we need to remember that a process is just a management object which contains the required resources to execute a program.įor a process to run, it must have a running thread which is the component that runs the code. Before moving onto performing process injection, we need to go over a bunch of terminology and theory. Typically speaking, this is for privilege escalation. Execution via process injection may also evade detection from security products since the execution is masked under a legitimate process.Įssentially, Process Injection is used to inject malicious code into another process. Running code in the context of another process may allow access to the process’s memory, system/network resources, and possibly elevated privileges. Process injection is a method of executing arbitrary code in the address space of a separate live process. The question looms then, what is process injection? Well, the Mitre ATT&CK Framework explains it as such:Īdversaries may inject code into processes to evade process-based defenses as well as possibly elevate privileges. Starting within this blog (part 1) where I’ll be breaking down some of the theory behind how and why process injection works, then another series or two breaking down some techniques and eventually finishing off with process injection in the face of Endpoint Detection and Response (EDR) Solutions. In this blog series, I want to formalise that. Process Injection is a term that encompasses a lot of prerequisite knowledge which is often taken for granted, and I’m writing this how I would have liked to find it when I first started looking into Process Injection. ![]() Read on for a detailed overview of this essential pentesting technique. Process injection is a defence evasion technique that any skilled penetration tester needs in their arsenal, but where to begin? We challenged Brandon – an Advanced Security Consultant and member of our Red Team here at Secarma – to guide readers through his process injection methods, providing all the info he wishes he was told when first learning.
