Vulnerabilities Addressed

Each case study highlights how attackers exploited systemic weaknesses, and how the OCS Network provides the definitive defense. Our L2 architecture replaces flawed custodial trust with cryptographically enforced policy.

Case Study: Centralized Custodian Failure

The 2025 Coinbase breach, which affected the founder, revealed that failures were not about weak user security, but about systemic gaps in administrative and technical controls at a major custodial exchange. Even when suspicious activity was reported, centralized workflows still allowed unauthorized transactions to proceed.

Vulnerability/FlawOCS Network Protocol FeatureCategoryMitigation Rationale
Custodian-enforced transactions allowed during active investigationE5 — Incident “Pause” Mode; E4 — Pre-check Async VerdictPGTAIL ProtocolThe L2 Sequencer is cryptographically forced to obey an immediate global/user-defined pause, regardless of internal custodian workflow.
No mandatory security hold / bulk asset drainage riskB6 — Multi-sig in-policy; E1 — Velocity & anomaly rulesSmart Account PolicyNative Smart Account rules prevent large, anomalous transfers instantly (Velocity Limit) or require multiple signatures (Multi-Sig).
Fraudulent recipient / bank account linking allowedB2 — Address Lock / Whitelist; E3 — Sanctions & heuristics checksPGTAIL Protocol / PolicyUser’s on-chain whitelist (B2) and PGTAIL risk scoring (E3) natively block transfers to un-approved or high-risk addresses.
Compromised support workflows used to bypass controlsD4 — Session Attestation; F3 — Forensics BundleRuntime IntegrityProtocol-level enforcement ensures internal support workflows hold no master key or override authority over user assets.

Mitigation Summary: The OCS Network eliminates this entire threat vector by removing the custodian. Asset movement is governed by the user's Smart Account (B6, E1) and the native policy rejection of the L2 Sequencer (E4, E5).

Case Study: Code Supply-Chain Attack

This incident highlighted the fragility of software supply-chains: a malicious package update silently replaced cryptocurrency recipient addresses on the fly. Attackers bypassed user vigilance, but the OCS Network's fail-safe mechanisms would prevent asset drain, even if the front-end code is compromised.

Compromised dependency / injected payload in web appA1 — Deterministic builds; A2 — Sigstore/Cosign; A6 — Emergency quarantineSupply-Chain SecurityCode integrity features ensure malicious code cannot enter the Sequencer or client application stack.
Tampered scripts modifying recipient address in front-end UIC2 — Clipboard detection; C5 — Mempool simulator; D1 — Tamper-evident UIRuntime IntegrityMulti-layer client checks prevent silent address manipulation, which is then vetoed by the on-chain whitelist (B2).
No containment / kill-switch during live exploitE5 — Incident “Pause” Mode; G4 — Incident PlaybooksIncident ResponseThe E5 feature provides an immediate, protocol-enforced network-wide lockdown of new recipient addresses.

Mitigation Summary: OCS uses defense-in-depth (A1, C5, D1) combined with the ultimate guardrail: even a maliciously signed transaction is blocked by the Smart Account's on-chain whitelist (B2), which the attacker cannot bypass.

These features form the backbone of the OCS Network’s PGTAIL framework — protecting against every major vector of digital asset compromise.
