Never execute unknown binaries on personal or production systems. Prefer snapshots, host-only networking, and clear sample handling policies.
Environment checklist
- Analysis VM or container is disposable and snapshotted before each sample.
- Host OS is patched; shared folders are read-only or disabled when possible.
- Network is host-only / simulated; no bridging to production or home LAN.
- Sample storage is labeled and separated from notes and clean tooling.
- Transfer path is intentional (hashed archive), not casual USB drag-and-drop.
Handling rules
- Hash before and after transfers; record names carefully.
- Prefer password-protected archives for transport between lab machines.
- Do not open samples on the browser of a trusted daily-driver machine.
- Reset to a clean snapshot after dynamic runs — especially after ransomware or bootkits in training kits.
If something escapes the lab
Disconnect the lab network, preserve volatile evidence if your exercise requires it, and treat the incident as a real containment drill. Document what failed in the isolation design so the next session is safer.
