All press releases IBM 2026 X-Force Threat Index: AI-Driven Attacks are Escalating as Basic Security Gaps Leave Enterprises Exposed Feb 25, 2026 ARMONK, N.Y., Feb. 25, 2026 /PRNewswire/ -- IBM (NYSE: IBM) today released the 2026 X-Force Threat Intelligence Index, revealing that cybercriminals are exploiting basic security gaps at dramatically higher rates, now accelerated by AI tools that help attackers identify weaknesses faster than ever. IBM X‑Force observed a 44% increase in attacks that began with the exploitation of public-facing applications, largely driven by missing authentication controls and AI-enabled vulnerability discovery. Some of the key highlights include: Active ransomware and extortion groups surged (49%) year over year, marking ecosystem fragmentation, while publicly disclosed victim counts rose roughly 12%. Large supply chain and third-party compromises nearly quadrupled since 2020, as attackers increasingly exploit environments where software is built and deployed or SaaS integrations. Vulnerability exploitation became the leading cause of attacks, accounting for 40% of incidents observed by X-Force in 2025. "Attackers aren't reinventing playbooks, they're speeding them up with AI," said Mark Hughes, Global Managing Partner for Cybersecurity Services, IBM. "The core issue is the same: businesses are overwhelmed by software vulnerabilities. The difference now is speed. With so many vulnerabilities requiring no credentials, attackers can bypass humans ...
