# Attack Vectors Given that interoperability protocols and bridges have been targeted by sophisticated black-hat hackers (including state-sponsored actors), it is imperative that we have an understanding of the most common ways these protocols have been targeted. After going through the most recent exploits and vulnerabilities, we've grouped the attack vectors into three large buckets: * [**Key compromise**](/the-nomad-protocol/security/attack-vectors/key-compromise.md) via server exploits and basic phishing attacks * [**Economic attacks**](/the-nomad-protocol/security/attack-vectors/economic-attacks.md), including [Sybil attacks](https://en.wikipedia.org/wiki/Sybil_attack) on validator sets * [**Smart contract bugs**](/the-nomad-protocol/security/attack-vectors/smart-contract-bugs.md) and code quality vulnerabilities Each of these considerations warrants its own discussion, and will be covered in the following sections. We will also discuss how the Nomad system architecture and the Nomad core team operating processes helps reduce risks on each of these fronts. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.nomad.xyz/the-nomad-protocol/security/attack-vectors.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
