💸 Cryptojacking Attack: When Hackers Mine Crypto Using Your Device
Ever felt your computer or phone getting unusually slow? It might not be a virus — it could be cryptojacking. In this type of cyberattack, hackers secretly use your device to mine cryptocurrency without your permission.
💰 What Is Cryptojacking?
Cryptojacking is when attackers run cryptocurrency mining scripts on your device — silently in the background. You don’t see it, but your system resources (CPU/GPU) are being drained to earn digital coins for the attacker.
⚙️ How It Happens
- 📩 Malicious links – One click downloads a hidden mining script
- 🌐 Infected websites – A JavaScript miner runs when you visit the page
- 🧩 Browser extensions – Some shady add-ons include built-in miners
- 💼 Compromised apps – Especially on mobile or third-party stores
🧨 Why It’s a Problem
- 🔋 Slows down your device
- 🔥 Overheats your CPU
- 💸 Wastes electricity and data
- 😶 Often goes undetected for weeks or months
Unlike ransomware, cryptojacking doesn’t lock your files — but it steals your resources every second it's running.
🛡️ How to Protect Yourself
- 🧰 Use antivirus and anti-malware tools with cryptojacking protection
- 🧩 Avoid unknown browser extensions or apps
- ⚠️ Block mining scripts with extensions like NoCoin or uBlock Origin
- 🔄 Keep your browser and OS fully updated
- 📊 Monitor your system performance regularly (spikes = red flag)
✅ Final Thoughts
Cryptojacking is a silent thief. You won’t get a warning or a ransom note — just a slow, hot, overworked device.
Stay secure, stay fast — and don’t let others mine on your machine.
