Lab Hooks Only
Lab hooks only means Frida/adb dynamic work on YOUR $MOB_LAB intentional apps — explicit refusal of stranger and production targets.
Visual · t27_lab_hooks_only
Lab hooks refusal. $MOB_LAB only. Original Cyberlium.
Opening
If the app is not on YOUR lab inventory, the hook does not run — no exceptions for trending APK tutorials.
Allowed hook targets: DVIA, MSTG/UnCrackable samples, InsecureBankv2-class courseware, debug builds YOU compiled with known flaws. Refused: stranger phones, production finance/social apps, any APK without written rules of engagement or bug-bounty scope. Cyberlium writes hook allowlist and NEVER list into YOUR $MOB_LAB dynamic ethics card — refuse copy-paste Frida repos aimed at live services. Next: Dynamic Lab.
1. Allowlist patterns (named)
Package names from course LMS, YOUR applicationId in build.gradle debug variant, OWASP MSTG crackmes with explicit training license. Emulator-only sessions with snapshot revert after hook experiments.
On $MOB_LAB, list three allowed package names and source (course, self-built, MSTG).
Command guide
Try these commands — Allowlist patterns (named)
═══ LINUX / macOS (Terminal Practice) ═══
Check system state and user context
Command — copy this
id whoami uname -a
Inspect network sockets listening for connections
Command — copy this
ss -tuln 2>/dev/null || netstat -tuln
Audit active processes
Command — copy this
ps aux | grep -v "\[" | head -15
═══ WINDOWS (POWERSHELL) ═══ Query user identity and system information
Command — copy this
whoami /all Get-ComputerInfo | Select-Object CsName, OsName, OsVersion
Primary tools to practice this lesson: grep, python3. Reference sites: Frida best practices (https://frida.re/docs/home/); OWASP MASTG runtime (https://mas.owasp.org/MASTG/0x05j-Testing-Resiliency-Against-Reverse-Engineering/); Android security tips (https://developer.android.com/privacy-and-security/security-tips). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Refusal patterns (named)
NEVER: hook com.chase.*, com.paypal.*, or any production app 'to learn.' NEVER: attach to classmate personal apps. NEVER: ship hook scripts labeled 'works on all apps.'
When tutorials target production, rewrite learning goal to named literacy on lab APK — do not execute.
3. Dynamic ethics card
Forbidden: combining adb backup + Frida on unauthorized targets. Allowed: dynamic ethics card — allowlist, NEVER list, snapshot/revert habit, refusal sentence.
Ship: dynamic ethics card for $MOB_LAB hooks. Next: Dynamic Lab.
4. What you ship: dynamic ethics card for $MOB_LAB
Hook allowlist, NEVER list, snapshot habit. $MOB_LAB named. NO stranger apps. chmod 600.
5. What you record before the next lesson
Date. Dynamic ethics card. $MOB_LAB named. File t27-m04-l03-lab-hooks-only.txt chmod 600.
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
Label hook script 'universal bank bypass.' Attach Frida to roommate social app.
Right
Write dynamic ethics card for YOUR $MOB_LAB hook allowlist. Next: Dynamic Lab.
Mission: write YOUR hook allowlist
1) List three allowed lab packages. 2) Write three NEVER hook targets. 3) Note emulator snapshot revert habit. 4) chmod 600.
