Purple › Module 1 › Lesson 3
No Stranger Sims
No stranger sims means refuse attack simulations on third-party networks, running offensive tools on systems you do not own, and unauthorized live-breach replication — write the refusal habit into YOUR $PURPLE_LAB ethics card.

Stranger-network sim refusal. $PURPLE_LAB only. Original Cyberlium.
Opening
Stranger ISP links, third-party cloud tenants, and unauthorized production simulation — all stop outside YOUR lab host scope. Literacy names the risk; sims stay on hosts you own.
Unauthorized purple actions include simulating attacks against stranger networks without legal authorization, running Atomic Red Team on third-party SaaS tenants, deploying destructive payloads on systems you do not own, and scraping victim data without legal scope. Org scope follows ownership: employer networks require written exercise authorization — stranger networks stay off limits. Cyberlium practices refusal sentences on YOUR $PURPLE_LAB — 'I practice purple teaming on MY lab hosts and name risks for detection context' — never copy workflows that aim simulations at networks you do not operate. Next: Lab Setup.
1. Stranger sim patterns refused (named, literacy only)
Stranger-network attack simulation: running offensive tools against ISP or cloud networks you do not own — named for literacy, NOT executed on Cyberlium. Third-party tenant targeting: simulating against SaaS subscriptions without contract — defender fix is lab host exercises, not student replication.
On $PURPLE_LAB, write three refusal triggers — e.g., stranger-network sim request, third-party tenant targeting, unauthorized live-breach replication.

SCOPE: YOUR lab folder $HOME/cyberlium-lab/t35-purple/ — rules, FAKE telemetry, exercise plans only
NEVER: attack simulations against production stranger networks
NEVER: ransomware atomics; credential dump atomics as homework (Mimikatz, lsass, etc.)
NEVER: destructive stranger sims; unauthorized red-team actions
ALLOWED: Sigma YAML stubs; FAKE auth.jsonl; jq rule validation; exercise plan + coverage CSV
ALLOWED: Atomic repo clone/read + list tests; Invoke-AtomicTest ONLY on YOUR lab VM + safe tests (T1082)
PURPOSE: purple literacy — validate detections on YOUR lab — not offensive homework

python3 -c "print('Ethics: stranger-network sims = legal/ops risk — YOUR lab hosts only')"Primary tools to practice this lesson: grep, python3. Reference sites: Atomic Red Team (https://github.com/redcanaryco/atomic-red-team); MITRE ATT&CK (https://attack.mitre.org/); CISA (https://www.cisa.gov/). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Why refusal protects you and others
Unauthorized simulation violates laws, platform terms, and employer policy — skill without scope is career and legal risk. Victim harm: simulating against stranger infrastructure or deploying payloads hurts real people and services you must not enable.
Defenders exercise through authorized change control, exercise plans, and org-owned lab hosts — students practice naming these channels for detection notes on lab scenarios only.
3. Ethics card habit
Forbidden: sharing stranger-network sim tutorials in class chat, importing live victim breach scripts, running Atomic Red Team against unauthorized targets. Allowed: ethics card — allowed lab host sources, NEVER list, refusal sentence you will say aloud.
Ship: purple ethics card with NEVER list and one refusal sentence. Next: Lab Setup.
4. What you ship: purple ethics card for $PURPLE_LAB
Allowed lab host sources, NEVER list, refusal sentence. $PURPLE_LAB named. NO stranger sims. chmod 600.
5. What you record before the next lesson
Date. Ethics card. $PURPLE_LAB named. File t35-m01-l03-no-stranger-sims.txt chmod 600.
6. Wrong vs right: stranger networks vs YOUR purple lab
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
Wrong
Follow stranger-network sim tutorial 'for purple practice.' Share live victim breach script in Discord.
Right
Write purple ethics card for YOUR $PURPLE_LAB. Next: Lab Setup.
Mission: write YOUR stranger-sim refusal habit
1) List three NEVER targets (stranger-network attack sims, third-party tenant targeting, unauthorized live-breach replication). 2) Write one refusal sentence for unauthorized sim requests. 3) Name allowed $PURPLE_LAB host sources. 4) chmod 600.
