Quick Answer
The answer is DLL injection, as this technique directly enables a process to load a malicious DLL into the address space of a legitimate system process like svchost.exe. This is accomplished using Windows API calls such as CreateRemoteThread and LoadLibrary, which force the target process to execute the injected code within its trusted context, thereby blending malicious activity with normal system operations and evading standard detection. On the Systems Security Certified Practitioner SSCP exam, this scenario tests your understanding of process injection methods and their role in privilege escalation or persistence, often appearing in incident response questions where memory forensics reveals abnormal code execution within critical Windows services. A common trap is confusing DLL injection with process hollowing or APC injection, but remember that DLL injection specifically relies on loading a library into an existing process’s memory space. Memory tip: think “DLL = Dynamic Link Library, injected into a trusted host to hide in plain sight.”

Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Process hollowing
Why wrong: Process hollowing replaces the legitimate process's code, not injection.
Reflective DLL injection
Why wrong: Reflective DLL injection is a variant but not the most common; DLL injection is broader.
Token stealing
Why wrong: Token stealing is used for privilege escalation, not code injection.
DLL injection

Correct answer & explanation
DLL injection
DLL injection is the most likely technique because it involves a process loading a malicious DLL into the address space of a legitimate process like svchost.exe. This is typically achieved using Windows API calls such as CreateRemoteThread and LoadLibrary, allowing the attacker to execute code within the trusted svchost.exe context, evading detection by blending in with legitimate system processes.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Process hollowing
Why it's wrong here
Process hollowing replaces the legitimate process's code, not injection.
Reflective DLL injection
Why it's wrong here
Reflective DLL injection is a variant but not the most common; DLL injection is broader.
Token stealing
Why it's wrong here
Token stealing is used for privilege escalation, not code injection.
DLL injection
Why this is correct
DLL injection loads a malicious DLL into a target process.
Clue confirmation

Common exam traps
The trap here is that candidates often confuse DLL injection with process hollowing, but process hollowing replaces the process's code entirely, whereas the question describes injecting code into an already running svchost.exe, which aligns with DLL injection.
Detailed technical explanation
DLL injection via CreateRemoteThread and LoadLibrary works by allocating memory in the target process (VirtualAllocEx), writing the DLL path (WriteProcessMemory), and then creating a remote thread that calls LoadLibrary, which loads the DLL from disk. In contrast, reflective DLL injection loads the DLL entirely from memory, avoiding disk writes and standard API hooks, but it requires more complex implementation and is less common in basic attacks. Real-world malware like Emotet has used DLL injection into svchost.exe to maintain persistence and evade detection by security tools that monitor for anomalous process creation.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A SOC analyst notices unusual lateral movement in the network at 2 AM. The IR playbook dictates: identify and contain (isolate the affected machine), then eradicate (remove the malware), then recover (restore from backup), then document. Skipping containment before eradication risks the attacker regaining access. Questions like this test the sequence and rationale of incident response phases.
