Microsoft’s 2026 Digital Defense Report says AI is already speeding up cyberattacks, compressing parts of the kill chain from days to minutes and setting up a multi-year rise in known but unpatched flaws. The company says attackers are getting the benefits first, while defenders are still working through normal validation and rollout cycles.
In plain terms, AI is helping with the tedious parts of offense: finding bugs in code and binaries, drafting phishing lures, generating malware, and moving faster after compromise. That speed matters because a flaw can be discovered, weaponized, and used before defenders finish the usual response window, while stolen credentials and lateral movement can unfold before containment catches up.
The pressure point is identity and data access, especially in environments where AI agents can read information or act on systems. If an attacker inherits that agent’s trust, the exposure moves with it across the data and control plane, and the remaining risk is less about one exploit than about how much standing access the environment already gave away.
