defi-attack-patterns

An offensive-security playbook in the yaklang hack-skills collection, focused on attack patterns against decentralized finance (DeFi) protocols for authorized security review and smart-contract auditing. Per its description it covers categories such as flash loan attacks, price oracle manipulation, MEV (maximal extractable value) sandwich attacks, governance exploits, cross-chain bridge vulnerabilities, and token-standard edge cases. It is framed as an expert playbook for analysts assessing the economic and logic-level security of DeFi systems, where risks often stem from protocol design and incentive structures rather than conventional code bugs. In a catalog context it is best understood as tooling for smart-contract auditors, protocol security researchers, and blue teams stress-testing their own deployments. Because the same knowledge can be misused against live protocols, it should be applied only to systems the user is authorized to test or in research and audit settings. Teams building DeFi protocols can treat the same categories as a threat-model checklist, reviewing oracle design, governance safeguards, bridge trust assumptions, and flash-loan resistance.
