Evidence Pack
Bundle Topic 26 literacy evidence from $DFIR_LAB — case lab, report, timeline, exhibits; no tampering.
Visual · t26_evidence_pack
Evidence pack = mentor handoff from $DFIR_LAB literacy. Original Cyberlium.
Opening
One indexed pack beats scattered PCAP notes — and never includes a forged log or unauthorized disk image.
Assemble evidence pack: $DFIR_LAB RoE/authority, dataset inventory, net/logs lab, timeline lab, report lab, case lab handoff, integrity statement (authorized practice only, hashes verified, no tampering, limitations documented). Directory chmod 600 — index.md lists contents UTC redactions. Mentor copy: report + diagrams + exhibit table, not live malware on USB. Gap paragraph for Topic 27 Mobile Security — separate authorized track. Scan folder for leaked dumps, planted metadata, unauthorized paths — zero tolerance.
1. Pack contents
Minimum: authority, inventory, net/logs, timeline, report, case index, integrity.
Optional: pitfalls checklist — no refused source artifacts.
Command guide
Try these commands — Pack contents
═══ LINUX / macOS (Malware Static & Dynamic Triage) ═══
Inspect PE / ELF binary headers and sections
Command — copy this
readelf -h sample.bin 2>/dev/null || xxd -g 1 -l 32 sample.bin
Check binary entropy (high entropy often signals packed or encrypted payloads)
Command — copy this
python3 -c "
import math, sys
data = open('sample.bin', 'rb').read() if len(sys.argv) > 1 else b'MZX\x00\x90'
ent = -sum((data.count(bytes([b]))/len(data))*math.log2(data.count(bytes([b]))/len(data)) for b in set(data))
print(f'Calculated File Entropy: {ent:.4f} (Entropy > 7.0 suggests packed/encrypted)')
" sample.bin 2>/dev/nullPrimary tools to practice this lesson: grep, python3. Reference sites: Timeline capstone (https://www.sans.org/cyber-security-skills/digital-forensics/); Autopsy timeline (https://www.autopsy.com/); CISA IR (https://www.cisa.gov/topics/cybersecurity-best-practices/incident-response). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Index fields
Artifact name, module lesson, path, UTC date, description, redactions applied.
Checklist row ↔ index row accountability.
3. Integrity
$DFIR_LAB only, legal reporting discipline, no tampering, share-safe export.
Scan before seal — remove accidental temp mounts or unhashed exports.
4. What you ship: DFIR literacy evidence pack
Bundled deliverables + index + integrity — chmod 600, report not tampering default.
5. What you record before the next lesson
Evidence pack path.
6. Wrong vs right: tampering evidence vs chain of custody
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
Wrong
Evidence pack includes leaked disk and forged Event logs.
Right
Evidence pack assembled. Next: Capstone Lab.
Mission: assemble evidence pack
1) Bundle case report timeline inventory index. 2) Integrity statements. 3) Confirm zero refused source files. 4) Gap note for Topic 27 Mobile Security.
