What is a supply chain attack in crypto and how to prevent it?

Supply chain attacks in crypto exploit trusted dependencies, emerging as a major threat to crypto projects, which now have to stay vigilant on such threats.

A supply chain attack in the crypto domain is a cyberattack where hackers target third-party components, services or software that a project relies on instead of attacking the project itself. These components may include libraries, application programming interfaces (APIs) or tools used in decentralized applications (DApps), exchanges or blockchain systems.

By compromising these external dependencies, attackers can insert harmful code or gain unauthorized access to critical systems. For instance, they might alter a widely used open-source library in DeFi platforms to steal private keys or redirect funds after it is implemented.
