The cybersecurity industry has spent the last several years chasing sophisticated threats like zero-days, supply chain compromises, and AI-generated exploits. However, the most reliable entry point for attackers still hasn’t changed: stolen credentials.
Identity-based attacks remain a dominant initial access vector in breaches today. Attackers obtain valid credentials through credential stuffing from prior breach databases, password spraying against exposed services, or phishing campaigns — and use them to walk through the front door. No exploits needed. Just a valid username and password.
What makes this difficult to defend against is how unremarkable the initial access looks. A successful login from a legitimate credential doesn’t trigger the same alarms as a port scan or a malware callback. The attacker looks like an employee. Once inside, they dump and crack additional passwords, reuse those credentials to move laterally, and expand their foothold across the environment. For ransomware crews, this chain leads to encryption and extortion within hours. For nation-state actors, the same entry point supports long-term persistence and intelligence gathering.
AI Is Accelerating What Already Works
The fundamental attack pattern here hasn’t changed much. But what has changed is the speed and polish with which it gets executed. Attackers are leveraging AI to scale their operations by automating credential testing across larger target sets, writing custom tooling faster, and crafting phishing emails that are materially harder to distinguish from legitimate communications.
This acceleration puts additional pressure on already-stretched defenders. Breaches are unfolding faster, spreading further and touching more of the environment, from identity systems to cloud infrastructure to endpoints. IR teams built for a slower tempo of engagement are finding that their existing processes can’t keep pace.
