Observes runtime behavior of binaries via QEMU emulation, GDB debugging, and Frida hooking — syscall tracing, breakpoints, memory inspection, and function interception. Use when running, tracing, or debugging a binary, verifying hypotheses from static analysis, or watching actual syscalls, network calls, or file access; requires human approval before any execution.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Dynamic Analysis (Phase 4)

## Purpose

Observe actual runtime behavior. Verify hypotheses from static analysis. Capture data that's only visible during execution.

## Human-in-the-Loop Requirement

**CRITICAL: All execution requires human approval.**

Before running ANY binary:
1. Confirm sandbox configuration is acceptable
2. Verify network isolation if required
3. Document what execution will attempt
4. Get explicit approval

## Platform Support Matrix

| Host Platform | Target Arch | Method | Complexity |
|---------------|-------------|--------|------------|
| Linux x86_64 | ARM32/64, MIPS | Native `qemu-user` | Low |
| Linux x86_64 | x86-32 | Native or `linux32` | Low |
| macOS (any) | ARM32/64 | Docker + binfmt | Medium |
| macOS (any) | x86-32 | Docker `--platform linux/i386` | Medium |
| Windows | Any | WSL2 → Linux method | Medium |

### macOS Docker Setup (One-Time)

```bash
# Start Docker runtime (Colima, Docker Desktop, etc.)
colima start

# Register ARM emulation handlers (requires privileged mode)
docker run --rm --privileged --platform linux/arm64 \
  tonistiigi/binfmt --install arm
```

How to install

The exact contents, by fingerprint
mdr add 2389-research/binary-re/binary-re:dynamic-analysis@sha256:945f75ac3b5a45dd

The line at the top of this page pins the label git:20260706.1bbfa9b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
