The Full form of HACKER is as below :

H : Hide IP

A : Aim Victim

C : Crack Encrypt

K : Kill Firewall

E : Enter into the Database

R : Return Anonymous

H — Hide IP

Matlab hacker sabse pehle apna IP address chhupata hai, taaki wo trace na ho sake.
IP address ek unique identity hoti hai internet par — agar ye chhup gaya, to uska location ya source track karna mushkil ho jata hai. Iske liye hacker VPN, proxy servers, TOR network jaise tools ka use karta hai.

A — Aim Victim

Phir hacker apne target/victim ko identify karta hai.
Ye koi individual, company, ya organization ho sakta hai. Victim choose karne ke baad, wo uske system, network, ya application ke baare mein research karta hai — jise reconnaissance bolte hain.

C — Crack Encrypt

Hacker encryption ya password systems ko todne ki koshish karta hai.
Encryption ek tarah ka security layer hota hai jo data ko secure banata hai. Hacker brute force, dictionary attacks, ya social engineering ka use karke is encryption ko crack karta hai.

K — Kill Firewall

Yahan wo system ke firewall ko disable ya bypass karta hai.
Firewall ek security mechanism hota hai jo unauthorized access ko block karta hai. Hacker firewall ko ya to exploit karta hai, ya koi aisa malware bhejta hai jo usse quietly bypass kar le.

E — Enter into the Database

Ab wo database tak access pa leta hai, jahan pe sensitive information hoti hai — jaise login credentials, user data, financial records, etc.
Ye access use SQL injection, backdoors, ya system vulnerabilities ke through milta hai.

R — Return Anonymous

Apna kaam karne ke baad hacker trace na hone ke liye apne tracks ko erase karta hai.
Wo logs delete karta hai, malware ko self-destroy mode mein daalta hai, aur system se is tarah nikalta hai jaise wo kabhi wahan tha hi nahi.

Explanation :

Ek hacker wo vyakti hota hai (kabhi-kabhi poori team bhi ho sakti hai) jise computer programs ka bahut gehra gyaan hota hai. Wo apni networking skills ya kisi aur hacking techniques ka use karke illegally computer system ki information ko manipulate karta hai.

Wo confidential ya sensitive data chura sakta hai, systems ko damage kar sakta hai, ya fir kisi dusri organization ke operations ko disturb kar sakta hai — bina kisi permission ke.

⚠️ Note: Har hacker illegal nahi hota. Kuch hackers ethical bhi hote hain — jaise white hat hackers, jo systems ki vulnerabilities dhoond kar unhe secure karne mein madad karte hain.

Ye explanation black hat hackers ke perspective se hai — jo illegal hacking karte hain.
