AN0297: Analytic 0297
Detects PE injection through a behavioral sequence where one process opens (OpenProcess) a handle to another, allocates remote memory (VirtualAllocEx), writes a PE header (MZ) or shellcode (WriteProcessMemory), then initiates a new thread (CreateRemoteThread or NtCreateThreadEx) in that process—executing injected code in memory without touching disk. Optional: injects a trampoline or shellcode that unpacks/reflectively maps the payload.
Analyst context for executives and security teams
This analytic is about spotting Windows process injection behavior where code is placed into another process and run from memory rather than written to disk. For leaders, the significance is that this kind of behavior can bypass file-focused controls and make incident scoping harder unless endpoint telemetry captures process access, memory allocation, memory writes, and remote thread creation events.
Executive priority
Prioritize this as a validation item for endpoint visibility and response readiness on Windows systems. The business question is not only whether malware is blocked, but whether the SOC can prove when one process manipulates another in memory, investigate the source and target process, and preserve enough evidence for containment, compliance reporting, and post-incident assurance.
Technical view
For SOC and detection engineering teams, validate whether Windows endpoint telemetry can correlate a behavioral chain involving a process opening a handle to another process, allocating memory in that remote process, writing PE-like content or shellcode indicators, and starting execution through remote thread creation APIs such as CreateRemoteThread or NtCreateThreadEx. Because no official detection logic is supplied, implementation should focus on correlation quality, process lineage, source and target process context, and expected administrative or security-tool behaviors that may resemble parts of the sequence.
Likely telemetry
- Windows endpoint process telemetry showing source and target process relationships
- API or EDR events for OpenProcess-style cross-process handle access
- Remote memory allocation events such as VirtualAllocEx
- Cross-process memory write events such as WriteProcessMemory
- Remote thread creation events including CreateRemoteThread or NtCreateThreadEx where available
Detection direction
- Validate correlation across the full sequence rather than alerting on a single API event in isolation.
- Tune for source process, target process, user context, signer, and parent-child lineage to reduce false positives from legitimate debuggers, security tools, administrative utilities, or application compatibility components.
- Confirm whether telemetry captures in-memory behavior; file, command-line, and network logs alone are unlikely to provide complete coverage for this analytic.
- Prioritize suspicious combinations where an unusual or low-reputation source process injects into a sensitive, long-running, or unexpected target process.
- Document gaps where EDR or audit configuration does not expose memory allocation, memory write, or remote thread creation details.
Mitigation priorities
- Ensure Windows endpoints that matter to business continuity are covered by telemetry capable of observing cross-process memory manipulation.
- Harden and monitor administrative privileges because process injection visibility and response depend heavily on user and process context.
- Use application control, least privilege, and endpoint protection policies to reduce opportunities for untrusted processes to execute and manipulate other processes.
- Prepare incident response procedures for collecting process lineage, memory-related telemetry, and affected host evidence when this analytic fires.
- Review detection coverage as part of compliance and resilience evidence, especially where fileless or memory-resident execution is in scope for risk assessments.
Analyst notes and limits
The ATT&CK object provides a behavioral description for a Windows detection analytic but does not include an official detection query, tactics, related techniques, or relationship context. Treat this as a coverage and validation guide rather than a ready-to-deploy rule.
This take is limited to the supplied STIX fields and the external MITRE reference. It does not establish active exploitation, attribution, prevalence, impact, or guaranteed detectability. Local endpoint tooling, logging depth, and baseline knowledge are required to determine practical coverage and false-positive rates.

Mirrored ATT&CK source object
The raw object is retained through the mirrored ATT&CK source bundle and object hash. The raw endpoint returns the exact object from the mirrored bundle when available.
External references and citations
MITRE external references are preserved separately from Glexia analysis so citations remain traceable to their original source records.
