Ransomware: Ek Detailed Guide Jisme Aapko Sab Kuchh Padhne Ko Milega

Introduction

Aaj ke digital zamanay mein, internet humari life ka ek important hissa ban gaya hai. Har roz hum apne kaam se lekar personal life tak sab kuchh online manage karte hain. Lekin jaise-jaise humari digital presence badhti hai, waise-waise cyber crimes, including Ransomware attacks bhi badh rahe hain. Ransomware ek aisa dangerous malware hai jo aapke computer ya mobile device ko lock kar deta hai, aur uske badle mein aap se ransom (paise) demand karta hai.

Is article mein, hum ransomware ke baare mein detail se jaanenge — yeh kya hota hai, kaise kaam karta hai, examples ke saath samjhenge, aur yeh bhi ki kaise aap apne data ko ransomware attacks se bachane ke liye secure rakh sakte hain.

Ransomware Kya Hai?

Ransomware ek type ka malicious software (malware) hota hai jo kisi bhi device (PC, smartphone, server, etc.) ko lock kar ke uspar access control le leta hai. Jab yeh malware aapke system mein enter kar leta hai, to aapka data encrypt ho jata hai aur aapko apna data wapas paane ke liye ransom (paise) dene ki dhamki milti hai.

Yeh cyber criminals aap se kuchh specific amount (jo aksar bohot bada hota hai) demand karte hain, aur agar aap paise nahi dete, toh wo aapka data permanently delete karne ya usse leak karne ki dhamki dete hain.

Ransomware Kaise Kaam Karta Hai?

Ransomware ke kaam karne ka process simple hai. Jab yeh aapke system mein enter karta hai, toh wo kuch is tarah se kaam karta hai:

1. Infection: Ransomware aapke system mein typically email attachments, malicious websites, infected software updates, ya phishing attacks ke through enter karta hai.
2. Encryption: Once ransomware aapke device ko infect kar leta hai, wo aapke files ko encrypt kar deta hai, jisse aap un files ko access nahi kar paate. Har file ke naam ke sath ek extension add kar di jaati hai (for example, .locked, .encrypted, etc.).
3. Ransom Demand: Jaise hi ransomware aapka system encrypt kar leta hai, aapke screen par ek message dikhayi deta hai jisme aapko ransom (paise) dene ke liye kaha jaata hai. Yeh ransom usually cryptocurrencies jaise Bitcoin mein hota hai, kyunki yeh transactions trace karna mushkil hota hai.
4. Payment Aur Decryption Key: Agar aap ransom dene ka decision lete hain, toh attacker aapko ek decryption key dega, jisse aap apne files ko restore kar sakte hain. Lekin, yeh guarantee nahi hoti ki wo aapke files ko restore karenge, aur aapka data bhi risk mein rehta hai.

Types of Ransomware

Ransomware kaafi varieties mein aata hai. Har type ka ransomware apne method aur targets mein thoda different hota hai. Kuchh popular types hain:

1. Crypto Ransomware:
   Crypto ransomware sabse zyada common type hai. Ismein, ransomware aapke files ko encrypt kar leta hai. Files ka access aapke paas nahi rehta, jab tak aap ransom nahi dete. Example: CryptoLocker.
2. Locker Ransomware:
   Is type ka ransomware aapke system ko lock kar deta hai, lekin wo aapke files ko encrypt nahi karta. Aapka system ya to boot nahi hota ya fir aapko desktop screen se access nahi milta. Example: WinLocker.
3. Scareware:
   Yeh ransomware users ko dar ke maare threat karta hai, jaise ki aapke system mein virus hai aur aapko turant fix karna hoga. Scareware ko generally bogus alerts aur pop-ups ke through distribute kiya jata hai.
4. Doxware/Leakware:
   Is type ka ransomware aapke personal files ya confidential data ko encrypt kar ke, uske badle mein aapko ransom demand karta hai. Agar aap ransom nahi dete, toh attacker aapka data leak karne ki dhamki deta hai. Example: Sodinokibi.
5. Ransomware-as-a-Service (RaaS):
   Yeh ek emerging type hai, jisme ransomware ko sale kiya jaata hai. Yani, ek person ransomware ko purchase karta hai aur doosre logon ko attack karne ke liye use karta hai. Is model kaafi dangerous hai, kyunki isse attacks increase ho rahe hain.
