AI-Powered Cyberattacks Accelerate at Lightning Speed

A new report from Microsoft warns that artificial intelligence (AI) is accelerating cyberattacks, making it challenging for defenders to keep up. According to the Digital Defense Report 2026, AI-powered attacks are compressing the attack lifecycle from days to minutes.

The report highlights that threat actors are leveraging agentic models to expedite various stages of attacks, including initial access and vulnerability discovery. This rapid acceleration necessitates a swift adaptation by defense strategies to close the widening gap.

Microsoft's report details how AI is transforming cyber threats by enabling attackers to discover vulnerabilities in code and AI systems, customize phishing campaigns at scale, and generate bespoke malware.
