Tonga

Hackers infiltrated Tonga's national health database, blocking medical personnel's access and forcing them to use paper records. The system stores confidential patient information used extensively in hospitals and clinics. The hackers demanded a $1 million ransom, which Tonga refused to pay. The country is still investigating the extent of the cyber-intrusion and the affected data.
