Lab: eradication/recovery pack on YOUR $HUNT_LAB host stub. Original Cyberlium.

Opening

Ship eradication-through-validation artifacts from YOUR lab host stub — zero malware authoring or unauthorized prod recovery.

On YOUR $HUNT_LAB per brief: (1) scope proof — post-containment lab host stub linked to Module 7 pack; (2) eradication checklist with validation stubs; (3) recovery plan row with monitoring window; (4) validation checklist with pass/fail criteria; (5) PICERL Eradication→Recovery timeline UTC; (6) integrity — $HUNT_LAB only, defender removal vocabulary not malware how-tos, no unauthorized prod changes; (7) chmod 600 pack. Cross-link containment lab — single incident narrative thread.

1. Lab deliverables

Eradication + recovery + validation — cross-indexed to one lab host incident thread.

Timeline shows PICERL stage transitions with evidence citations.

2. Quality bar

Fail loop documented if brief assigns failed check scenario — honest literacy.

Zero malware source or attack repro in pack.

3. Integrity

Validation fraud or prod recovery without RoE = zero credit.

Mentor pack chmod 600.

4. What you ship: eradication lab pack

Eradication + recovery + validation + timeline + integrity — chmod 600.

5. What you record before the next lesson

Eradication lab pack path.

6. Wrong vs right: stranger prod vs YOUR hunt telemetry

Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.

  • Wrong

    Eradication lab includes custom malware source as exhibit.

  • Right

    Eradication lab pack on $HUNT_LAB host stub. Next: quiz.

Mission: eradication lab

1) Scope and host stub proof. 2) Eradication and recovery rows. 3) Validation checklist. 4) Integrity block; chmod 600.
