Hands-on practice on systems and accounts YOU own.
Invoice Fraud Patterns
This lesson is part of Scam & Phishing Protection → Business Email Compromise. You learn defensive, professional habits: practice only on your devices, VMs, and $HOME/cyberlium-lab. Never scan, phish, or probe systems you do not own and are not explicitly authorized to test.
1. What you will understand
Professionals treat "Invoice Fraud Patterns" as a mechanism, not a buzzword. Read carefully, then run the commands on your own machine. If a command fails on your OS, note why — WSL, Kali, macOS, and Windows differ — and use the equivalent from Settings or PowerShell.
2. How defenders use this
You are training toward junior security work: clear notes, least privilege, verified updates, and ethical scope. Copyable commands below stay inside your lab folder or documentation hosts like example.com / 127.0.0.1.
3. Wrong vs right
Keep the blast radius tiny:
- Wrong: Run random scripts from the internet as root, scan strangers, or reuse live passwords in lab files.
- Right: Use $HOME/cyberlium-lab, prefer 127.0.0.1 / example.com, chmod 600 notes, and stop when scope is unclear.
4. Practical: terminal practice
Run these on YOUR Linux / Kali / macOS terminal (or PowerShell equivalents). Create the lab folder first if needed.
Command guide
Terminal practice (YOUR machine / cyberlium-lab only)
Command — copy this
cat > "$HOME/cyberlium-lab/bec-card.txt" << 'EOF' If payment/details change by email: 1) Stop 2) Call saved vendor/boss number 3) Never use contacts from the email body EOF
Mission
Complete the practice above, then write one sentence in $HOME/cyberlium-lab about what you observed for: Invoice Fraud Patterns.
Stuck? Ask Cyberlium AI Mentor
Ask for a hint — not a full answer. Stay inside ethical scope.
Next: Verification Channels. Keep building the habit: own machine, clear notes, professional ethics.
