Crypto Security Takes More Than Audits to Prevent Losses

Audits cut down on code bugs, but the biggest crypto losses now often come from keys, governance, and operational mistakes. Here’s why a broader security approach is needed.

Key Takeaways

• The number of code audits in crypto has tripled since 2022, but losses from hacks and exploits remain high.
• According to Oak Security, traditional audits focus mostly on code, while attackers are increasingly exploiting private keys, governance, and operational weaknesses.
• On top of audits, the industry needs a broader security approach, with strong key management, real-time monitoring, and staff training.

The crypto market has been dealing with serious security problems for years. Even though the number of code audits has tripled since 2022, losses from hacks and exploits remain high. Research from Oak Security shows that traditional audits mainly address weaknesses in code, while attackers are increasingly taking advantage of human and operational weaknesses. As a result, the number of incidents and the size of the losses remain stubbornly high.

Limits of Traditional Code Audits

The quality of code audits has improved a lot in recent years. Security firms use advanced tools to spot smart contract bugs early, which has led to fewer attacks based on code flaws. Still, the biggest losses today come from compromised private keys, governance manipulation, insider threats, malicious dependency updates, and operational mistakes. These weaknesses fall outside the scope of traditional audits, which mainly focus on the code itself.

It’s clear that even the best code does not help much if the underlying operational infrastructure is vulnerable. One example is the rise in attacks aimed at human factors, like phishing, which audits cannot prevent. That leads to major financial losses that the industry has so far not been able to reduce enough. In practice, that means the focus is increasingly on broader security, like in the U.S. approach to crypto theft, where prevention and enforcement come together.

The Illusion of Safety From Audits

A lot of crypto projects market their security by pointing to the number and reputation of the audits they’ve had. But that creates a false sense of safety. An audit is just a snapshot of a specific codebase within a certain scope, and it does not guarantee future security, especially when protocols are updated, governance changes, or operational processes are revised.

This misunderstanding can lead people to underestimate risks outside the code, even though that’s where the most serious threats often are. Users and teams may think security has already been handled, while the real weak spots are somewhere else.

Toward a Broader Security Approach

The industry can’t really expect mass adoption as long as trust keeps getting hit by repeated security incidents. On top of audits, it needs a deeper security strategy that addresses human and operational risks. That includes stronger key management systems, decentralizing signers, governance limits, real-time monitoring, and circuit breakers.

Crypto platforms are living organizations with human weak points, not just software products. Attackers have adapted their tactics and are actively looking for weaknesses in human systems. The next step in crypto security therefore requires a full approach that goes beyond code alone and focuses on the whole ecosystem of people, processes, and technology.

Why This Matters for European Crypto Users

For European users and projects, it’s important to understand that security does not stop at a positive audit. Operational risks and human factors can have a big impact here too, especially given the complexity of regulation and governance in Europe. It highlights the need for European crypto companies to invest not only in technical audits, but also in strong operational security and staff training to build user trust.
