Static triage of a Windows executable
| Evidence | What it answers |
|---|---|
| PE headers | 32/64-bit architecture, subsystem, sections, timestamps and basic build characteristics |
| Imports | Runtime libraries, Windows APIs, database clients, networking and device access |
| Resources | Version data, manifests, dialogs, icons, embedded configuration and language clues |
| Strings/configuration | Paths, registry keys, server names, file types, error messages and protocol clues |
| Signatures/hashes | Version identity and whether compared copies actually match |
Runtime observation
Run only in a controlled environment appropriate to the software’s trust level. Trace process creation, loaded modules, failed file opens, registry reads/writes, network connections, child processes and device access. Exercise known workflows with representative data and correlate each observation with an operator action.
- Capture baseline startup before changing compatibility settings.
- Separate loader failure from application-level configuration or database failure.
- Preserve environment variables, working directory and user privilege context.
- Compare a working machine when one exists.
What analysis can deliver
Useful outputs include a dependency map, deployment specification, configuration inventory, file/network interaction model and evidence for a replacement boundary. Exact original source, comments and design intent generally cannot be reconstructed from a native executable.
Use reverse-engineering services for a scoped operational outcome and the pillar for method selection. Unknown data generated by the program may require file-format analysis or database identification.
Provide
Executable and adjacent files, installer, configuration, hashes/versions, a working environment if available, known workflows and the decision the analysis must support.
