This Drift security incident can be said to have given the entire DeFi industry a harsh lesson.

Many people's first reaction was "Another contract vulnerability," but this time it's different. The real problem isn't in the code but in the permission system.

The core of the issue is simple: attackers didn't find a vulnerability overnight; they had already obtained the "legitimate execution capability" in advance. Through pre-signed transactions and gaps in permission design, they were able to transfer funds all at once at the right moment.

In other words, this isn't a traditional "hacking" event; rather, the system's logic allowed this to happen.

This is the most frightening part.

The industry has long emphasized one thing: how to protect private keys securely.
But this incident exposes another problem — even if the private keys are secure, the execution layer can still be exploited.

Signing is correct, and the people involved are correct, but the final outcome is wrong.

This means that the risks in DeFi have escalated from "code vulnerabilities" to "permission design."

Many people have always believed that multi-signature is secure, but in reality, multi-signature only disperses risk; it doesn't eliminate it. Once the permission structure is pre-arranged or participants are infiltrated, multi-signature can also be exploited.

This is also why this incident had such a big impact on the market.

Price drops are just superficial; what truly collapsed was trust.
When users realize that "rules themselves can be bypassed," the entire system's security expectations are reset.

Project suspensions and fund freezes are consequences, but not root causes.

The root cause is that many protocols, when designing, oversimplified the concept of "execution rights."

As long as there is room for human intervention in the system, there is always a possibility of exploitation.

This incident is actually a reminder to everyone:
On-chain does not equal absolute security.

As long as humans are involved, the attack surface will always exist.

And the protocols that will truly survive in the future are not those with the most complex code, but those that thoroughly dismantle permission, execution, and verification logic.

Security is not just about defending against hackers; it's also about preventing the system from malfunctioning itself. #DriftProtocol遭黑客攻击
