The Zscaler ThreatLabz 2025 Phishing Report unveils the alarming sophistication of modern phishing attacks, driven by generative AI (GenAI).
By examining over 2 billion blocked phishing transactions on the Zscaler Zero Trust Exchange™ cloud security platform from January to December 2024, the report highlights a seismic shift in cybercriminal tactics.
Cybercriminals Leverage GenAI for Hyper-Targeted Scams
Gone are the days of broad, scattershot phishing campaigns; today’s attackers wield AI to craft hyper-personalized lures that exploit human vulnerabilities with surgical precision.

HR, payroll, and finance teams are prime targets, as GenAI creates flawless emails, texts, and calls that bypass traditional defenses and manipulate trust.
The report notes a 20% drop in global phishing volume in 2024, yet this decline masks a dangerous pivot toward high-impact, targeted campaigns aimed at maximizing success rates against high-value individuals and organizations.
Emerging Threats and Advanced Tactics Dominate 2025 Outlook
The evolving phishing landscape paints a grim picture for 2025, with attackers adopting cutting-edge methods to outsmart AI-powered security tools.
Voice phishing (vishing) has surged, where fraudsters impersonate IT support to extract credentials in real-time conversations.
CAPTCHA protections are now weaponized to mask phishing sites, lending them an air of legitimacy while evading detection.
Cryptocurrency scams are skyrocketing, with fake wallets and exchanges tricking users into surrendering credentials and digital funds.
Additionally, the hype around AI itself is being exploited, as fraudulent “AI agent” websites mimic legitimate platforms to harvest sensitive data.
Education sectors face a staggering 224% spike in attacks, driven by weak defenses and exploitable academic schedules, while tech support and job scams rack up over 159 million hits, leveraging social media and live chat tools to deceive users.
Even as phishing in the United States declines by 31.8% due to robust email authentication like DMARC and Google’s sender verification, it remains the top global target.
Amidst this escalating threat landscape, Zscaler’s Zero Trust Exchange emerges as a formidable defense against AI-powered phishing.
By decrypting and inspecting TLS/SSL traffic inline, it blocks malicious content in real time while isolating suspicious sites in secure browser sessions to prevent drive-by downloads and zero-day exploits.
The platform curtails lateral movement through direct user-to-application connections and AI-driven segmentation, limiting breaches to siloed applications.
Context-aware policies, fortified by multi-factor authentication (MFA) and deception technologies, shut down compromised accounts and detect insider threats early.
Furthermore, real-time data loss prevention (DLP) safeguards sensitive information across apps, email, and GenAI tools, thwarting exfiltration attempts.
The report underscores that phishing is no longer mere inbox clutter but a sophisticated assault on human trust, yet with Zero Trust architectures, organizations can redefine their cybersecurity posture.
As cybercriminals harness AI to sharpen their attacks, the Zscaler solution offers a proactive shield, ensuring businesses stay one step ahead in this relentless digital arms race.
