Web3 Attack Surfaces: A Penetration Testing Overview
Crypto institutions keep every traditional attack surface and add the money-handling chain on top of it. This article gives testers a practical abstraction of the running system: a four-component model—Application, Authorization and Signing, Blockchain Interaction, and Infrastructure—with each component's responsibility, representative implementations, and inherited attack surfaces. It then structures web3-specific coverage into five attack-surface areas, from production and automation operations through signing intent, approval and withdrawal chains, and fund logic to on-chain transactions and deployed contracts.

Rules of Engagement and Production Safety for Institutional Blockchain Penetration Testing
A penetration test that touches signing, withdrawal, and ledger systems is prepared before it runs. This article follows the engagement lifecycle: turning a business decision into objective, scope, named owners, and authorized access; recording authority, permitted techniques, operating limits, prohibited activity, communications, and evidence handling in a Rules of Engagement document; and protecting live service with measurable stop criteria, monitoring, change coordination, and named pause authority. It closes with the remediation and retest that turn findings into validated controls.

What Is Blockchain Penetration Testing? Definitions and Boundaries
No widely accepted definition of blockchain penetration testing exists, and many proposed ones tangle it with audit, scanning, and bug bounty. This article sets out a working definition—an adversarial, hands-on assessment of a running system, under agreed scope and rules of engagement, that validates exploitable paths and control chains—and what web3 adds: a money-handling threat model whose defining composition gap is the off-chain-to-on-chain handoff. It then maps the five testable capabilities of that chain and routes nearby objectives to code audit, wallet security audit, web3 security testing, scanning, and bug bounty.
