Cross-Contract Exploitation

Cross-contract exploitation involves leveraging vulnerabilities across multiple interconnected smart contracts to achieve a malicious goal. Instead of attacking a single contract, an attacker might manipulate the interaction between two or more contracts to bypass security checks.

This often occurs when one contract trusts another implicitly without validating the inputs or state changes. These exploits are difficult to detect because they often appear as legitimate, albeit complex, transactions.

In decentralized finance, this requires a deep understanding of the entire protocol architecture rather than just individual components. Protecting against this requires comprehensive testing that covers the entire system's behavior.
