Hunting for Process Injection Techniques

Overview

Process injection (MITRE ATT&CK T1055) allows adversaries to execute code in the address space of another process, enabling defense evasion and privilege escalation. This skill detects injection techniques via Sysmon Event ID 8 (CreateRemoteThread), Event ID 10 (ProcessAccess with suspicious access rights), and analysis of source-target process relationships to distinguish legitimate from malicious injection.

When to Use

• When investigating security incidents that require hunting for process injection techniques
• When building detection rules or threat hunting queries for this domain
• When SOC analysts need structured procedures for this analysis type
• When validating security monitoring coverage for related attack techniques

Prerequisites

• Sysmon installed with Event IDs 8 and 10 enabled
• Process creation logs (Sysmon Event ID 1 or Windows 4688)
• Python 3.8+ with standard library
