Lab — MASVS
MASVS lab on $MOB_LAB — category checklist, MASTG mapping, secure coding fixes; defender verification pack.
Visual · t27_masvs_lab
Lab: MASVS verification pack on YOUR $MOB_LAB app. Original Cyberlium.
Opening
Ship a MASVS-aligned verification pack from YOUR lab app — categories, test IDs, fixes — no unauthorized prod targets.
On YOUR $MOB_LAB per brief: (1) app scope proof — name, version, authorization (DVIA/MSTG/instructor); (2) MASVS V1–V8 checklist with ≥5 finding rows citing evidence; (3) MASTG mapping ≥3 test IDs with observed artifacts; (4) secure coding fix table ≥5 rows; (5) observed vs inferred columns separate; (6) integrity — $MOB_LAB only, no stranger prod apps, no pinning bypass cookbooks; (7) chmod 600 pack. Cross-link Module 6 iOS rows if dual-platform brief. Retest stub optional.
1. Verification deliverables
Checklist + MASTG map + fix table — single app ID cross-indexed.
Minimum five evidenced findings — no checkbox-only compliance.

═══ INSTALL ═══
Linux (Debian/Ubuntu):
Command — copy this
sudo apt install curl
macOS: Built-in
Windows: Built-in (PowerShell: Invoke-WebRequest)
═══ LINUX / macOS ═══
Command — copy this
export MOB_LAB=${MOB_LAB:-$HOME/cyberlium-lab/t27-mob}
cat > "$MOB_LAB/notes/masvs-lab-map.txt" <<'EOF'
MASVS lab map (YOUR demo.apk / authorized MSTG sample):
MASVS-STORAGE: manifest allowBackup + lab note on Keychain/Keystore
MASVS-NETWORK: security-config literacy + openssl s_client exercise
MASVS-PLATFORM: exported components count from static review
MASVS-RESILIENCE: read MASTG chapter — no bypass scripts
scope: $HOME/cyberlium-lab/t27-mob/ only
EOFCommand — copy this
grep -E 'MASVS|scope|no bypass' "$MOB_LAB/notes/masvs-lab-map.txt" curl -sS https://mas.owasp.org/MASVS/ | head -5
Primary tools to practice this lesson: grep, curl. Reference sites: MASVS checklist (https://mas.owasp.org/MASVS/); MASTG test cases (https://mas.owasp.org/MASTG/); Portable Continuum (https://github.com/OWASP/MASTG). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Quality bar
Each finding cites path, screenshot hash, or log snippet reference on $MOB_LAB.
Severity tied to MASVS category impact — not CVSS theater alone.
3. Integrity
Unauthorized prod assessment = zero credit; pinning bypass on stranger app = refused.
Share-safe export redacts app secrets — mentor pack chmod 600.
4. What you ship: MASVS lab pack
Checklist + MASTG map + fix table + integrity — chmod 600.
5. What you record before the next lesson
MASVS lab pack path.
6. Wrong vs right: stranger phones vs lab emulator apps
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
Wrong
MASVS lab targets unauthorized banking app with bypass recipes.
Right
MASVS lab pack on $MOB_LAB. Next: quiz.
Mission: MASVS lab
1) App scope proof. 2) Five evidenced finding rows. 3) MASTG map three IDs. 4) Fix table; chmod 600.
