Cyber Security in Healthcare – Digital Threats and Protection Methods 🛡️💻
HealthSync Blog Series – Part 7
Healthcare sector එක cyber criminals ගේ #1 target වෙලා තියෙන්නේ ඇයි? 🎯
Digital health transformation එක advance වෙන්න advance වෙන ගමන්, cyber threats exponentially increase වෙනවා! 📈
🚨 Why Healthcare = Prime Target?
The Perfect Storm ⛈️
💰 High-Value Data:
- Medical records black market value: $250+ per record
- Credit card data: $5-10 per record only!
- Why expensive? Complete identity info + insurance details + medical history
🏥 Critical Operations:
- Patient lives depend on systems working 24/7
- Downtime = Deaths – හදිසි pressure ransom pay කරන්න
- Surgery machines, ventilators, monitoring systems connected
🔓 Weak Security:
- Old hospital systems outdated security
- Medical devices no security updates years
- Staff busy – security awareness low
Common Digital Threats
🦠 Ransomware Attacks
How it works:
Malicious email → Staff clicks link →
System encrypted → “Pay $1M or lose everything!” →
Hospital operations paralyzed
💉 Medical Device Hacking
Vulnerable Devices:
- Insulin pumps: Remote dose changes possible
- Pacemakers: Heart rhythm manipulation
- CT/MRI scanners: False readings injection
- Hospital WiFi: Unsecured device access
📧 Phishing & Social Engineering
Common Tricks:
- Fake emails: “Medical urgency – click here!”
- Phone calls: “IT department – need your password”
- USB drops: Parking lot එකේ infected USB leave කරනවා
Success Rate: 30% healthcare workers fall for phishing! 😰
