Executive Summary
Q1 2025 has seen a significant evolution in threat actor tactics, with AI-enhanced attacks becoming mainstream and supply chain compromises reaching new levels of sophistication.
Key Trends
AI-Powered Social Engineering
Threat actors are now using generative AI to create highly convincing phishing emails, voice clones for vishing attacks, and even deepfake video for executive impersonation.
| Threat Type | 2025 Trend |
|---|---|
| AI-generated phishing | 80%+ of phishing is AI-assisted |
| Deepfake vishing | 1,600% surge vs late 2024 |
| Polymorphic phishing | 90%+ campaigns rewrite per recipient |
Recommendation: Implement out-of-band verification for all financial transactions and sensitive requests.
Supply Chain Attacks Continue (T1195.002)
Following the pattern of the SolarWinds Orion breach (December 2020, SUNBURST) and the Kaseya VSA attack (July 2021, REvil), attackers are increasingly targeting software vendors and MSPs as vectors into their customers.
Recommendation: Implement vendor risk management programs and segment third-party access (T1199 – Trusted Relationship).
Ransomware Evolution
Ransomware groups have shifted to pure extortion models, exfiltrating data without encryption to avoid detection by endpoint tools focused on encryption behavior.
Recommendation: Deploy data loss prevention (DLP) and monitor for unusual data exfiltration patterns.
