Phishing remains the #1 cybersecurity threat in 2025, now powered by artificial intelligence (AI), deepfakes, and multi-channel delivery tactics. Attackers are crafting polymorphic phishing emails, SMS scams, and QR code lures that bypass traditional defenses. For CISOs and IT leaders, the challenge is clear: defending against phishing now requires a layered, AI-driven security strategy.
This blog explores phishing attack trends in 2025, the latest AI-powered tactics, and best practices to prevent breaches.
