Phishers also spoof social networks to distribute malware, mask C2 communications and gather target intelligence.
A sharp escalation in AI-driven phishing attacks targeting critical business operations including IT, HR, payroll, and finance has been detected.
According to research by Zscaler, phishing attacks are down globally by 20 percent, but attackers are going deeper, targeting high-value departments with precision.
Its analysis of over two billion blocked phishing attempts between January and December 2024 determined cyber-criminals are using Generative AI to launch surgical, targeted attacks against high-impact business functions.
It also determined that cyber-criminals are using GenAI to scale attacks, generate fake websites, and craft deepfake voice, video, and text for social engineering.
Phishing campaigns are increasingly abusing community-based platforms like Facebook, Telegram, Steam, and Instagram – not only spoofing their brands, but using them to distribute malware, mask C2 communications, gather target intelligence, and carry out social engineering attacks.
“The phishing game has changed. Attackers are using GenAI to create near-flawless lures and even outsmart AI-based defences,” said Deepen Desai, CSO and Head of Security Research, Zscaler.
“Cyber-criminals are weaponising AI to evade detection and manipulate victims, which means organisations must leverage equally advanced AI-powered defenses to outpace these emerging threats. Our research reinforces the importance of adopting a proactive, multi-layered approach - combining robust zero trust architecture with advanced AI-driven phishing prevention - to effectively combat the rapidly evolving threat landscape.”
