Detect process injection techniques (T1055) - including DLL injection, process hollowing, and APC injection - by analyzing Sysmon Event IDs 1, 7, 8, 10, and 25 for cross-process memory operations, remote thread creation, and anomalous DLL loads. Use when hunting defense-evasion activity that hides code inside legitimate processes, investigating an EDR alert on suspicious cross-process access, or validating Sysmon coverage for injection detection.

# Detecting T1055 Process Injection with Sysmon
## When to Use
- When hunting for defense evasion techniques that hide malicious code inside legitimate processes
- After EDR alerts for suspicious cross-process memory access or remote thread creation
- When investigating malware that injects into svchost.exe, explorer.exe, or other system processes
- During purple team exercises testing detection of process injection variants
- When validating Sysmon configuration coverage for injection detection
## Prerequisites
- Sysmon deployed with comprehensive configuration capturing Events 1, 7, 8, 10, 25
- Event ID 8 (CreateRemoteThread) enabled for remote thread detection
