What is Ransomware in 2025?
Ransomware is a type of malware that encrypts your files and demands payment (usually in cryptocurrency) to restore access. The newest 2025 ransomware variants are more advanced, targeting cloud backups, IoT devices, and even AI-powered security systems.
Why New Ransomware Attacks Are More Dangerous in 2025
- Ransomware-as-a-Service (RaaS) has lowered the barrier to entry.
- Zero-day exploits and supply-chain attacks are more common.
- Cloud and hybrid environments are targeted alongside endpoints.
- AI-crafted phishing emails are harder to spot.
