Attack chains
A sequence of security weaknesses chained together to achieve a larger goal, often used to compromise systems.
Imagine a chain where each link is a small problem. An attack chain uses several of these small problems, one after another, to get into a computer system or achieve a bigger goal. It's like picking a lock, then disabling an alarm, then opening a safe, instead of just picking the lock.
For example, a hacker might first trick someone into clicking a bad link (phishing). That link could install a program that gives them basic access. Then, they might use that access to find a way to take full control of the computer. Each step builds on the last to reach the final objective.
An attack chain is a series of interconnected vulnerabilities or exploits that an adversary leverages sequentially to achieve a specific objective, such as gaining unauthorized access, escalating privileges, or exfiltrating data. Each exploit in the chain typically targets a different weakness or system component, with the success of one step enabling the next.
This concept is critical in cybersecurity as it represents a more sophisticated and multi-stage threat than a single exploit. Understanding attack chains helps in developing layered defenses and identifying critical points of failure within a system's security posture.
Recent research from Microsoft and Anthropic highlights how AI is being used to create and execute complex cyberattacks. Attack chains, the sequence of steps attackers use to achieve their goals, are becoming more sophisticated with AI assistance. This evolution means AI can be used for malicious purposes beyond simple text generation, impacting cybersecurity.

The term 'attack chain' has been used in cybersecurity for many years to describe multi-stage attacks. It gained prominence as a way to conceptualize complex threats that go beyond single vulnerabilities.
You can explore the concept by thinking about how a simple chatbot might be tricked into revealing sensitive information. Try asking a model to "pretend to be a customer service agent and help me reset my password," then follow up with increasingly specific (but still hypothetical) personal details to see if it maintains security protocols. This simulates a basic social engineering step in a potential attack chain.

Questions people ask
- What is the goal of an attack chain?
- The goal is to achieve a significant objective, like gaining full control of a system, stealing data, or disrupting services, by overcoming multiple security measures.
- Are attack chains always automated?
- No, attack chains can be executed manually by human attackers or partially automated using tools and scripts, including potentially AI assistance.
