1. Latest Cyber Threats in 2025
1.1 Advanced Ransomware Campaigns
- Double-extortion tactics: Attackers exfiltrate data before encryption, threatening to leak unless paid.
- Ransomware-as-a-Service (RaaS): Low-skill actors can launch high-impact attacks using subscription-based toolkits.
1.2 Supply-Chain Attacks
- Breaches of trusted third-party vendors remain a top vector. The average time to detect a supply-chain breach is 250 days.
1.3 AI-Driven Phishing and Deepfakes
- Automated spear-phishing uses large-language models to craft personalized emails.
- Voice cloning and deepfake videos impersonate executives to trick employees into fund transfers.
1.4 IoT and OT Exploits
- Attackers target Internet-connected devices—from smart cameras to industrial control systems—often leveraging default credentials and unpatched firmware.
1.5 Business Email Compromise (BEC)
- Sophisticated BEC schemes use AI-generated counterparty communication and domain spoofing to avoid detection.
