AI Is Reducing the Reliability Window of Crypto Security Audits, Researchers Say

Cointelegraph also reports that hackers have been exploiting the codebases of defunct DeFi protocols, draining millions of dollars in customer funds. Projects that have been discontinued or left unmaintained can still hold live contracts and user assets, creating openings for attackers when no team remains active to patch flaws or respond to incidents.

This pattern highlights a structural challenge in decentralized systems: code deployed on public blockchains often continues to operate long after its creators have moved on. Without ongoing maintenance, weaknesses that would otherwise be addressed can persist and be targeted.

Implications for the Africa–Europe Corridor

The warning is relevant to the broader technology and business links between Africa and Europe, where crypto and DeFi tools are used for cross-border payments, remittances and access to financial services. Reliance on audited protocols is a common risk-management step for developers and businesses in both regions. If the assurance provided by audits erodes more quickly, firms may need to reassess how they evaluate the security of the platforms they build on or integrate with.

The researchers cited by Cointelegraph do not suggest that audits are without value, but rather that their findings should be understood as reflecting a specific moment in time. Combined with the risk posed by abandoned protocol code, the guidance points toward layered security practices—repeated assessments, active maintenance, and vigilance around older deployments—as the sector matures.

As AI capabilities continue to develop, both defenders and attackers are expected to adapt, keeping code security an evolving concern for the crypto industry in Europe and beyond.
