Mistake 1: Starting Without Written Permission

Biggest and most dangerous mistake. Testing any system you don’t own or have explicit written permission for is illegal in India (IT Act Section 43 & 66). Real case: A 19-year-old Mumbai student scanned his college network “just to test” and got FIR + college expulsion. Ethical Hacking Training Institute starts every batch with legal training. Find the best local courses that teach rules first.

Always Remember

• Real pentest needs signed Rules of Engagement

Mistake 2: Skipping Linux and Networking Basics

• 90 percent beginners jump to Metasploit
• Don’t understand TCP handshake, subnets, OSI
