Detecting Process Injection Techniques

When to Use

• EDR alerts on suspicious API call sequences (VirtualAllocEx + WriteProcessMemory + CreateRemoteThread)
• A legitimate process (explorer.exe, svchost.exe) exhibits unexpected network connections or file operations
• Memory forensics reveals executable code in memory regions that should not contain it
• Investigating living-off-the-land attacks where malware hides inside trusted processes
• Building detection logic for specific injection techniques in EDR or SIEM rules

Do not use for standard DLL loading analysis; injection implies unauthorized code placement in a process without that process's cooperation.

Prerequisites

• Volatility 3 for memory forensics analysis of injection artifacts
• Sysmon configured with Event IDs 8 (CreateRemoteThread) and 10 (ProcessAccess)
• API Monitor or x64dbg for observing injection API calls in real-time
• Process Hacker or Process Explorer for inspecting process memory regions
• Understanding of Windows memory management (VirtualAlloc, VAD, page protections)
