The attack that changes the question: what if the key was never stolen?
When a crypto attack is linked to private keys, the immediate reaction is usually: “the key was stolen.” The assessment presented by Ido Ben-Natan, CEO of Blockaid, raises a different possibility in the case involving Binance: attackers may have manipulated the infrastructure responsible for signing transactions, misusing the process without necessarily stealing the key itself.
This distinction may seem small, but it completely changes the security analysis. If the flaw lies in the signing environment, protecting only the cryptographic secret is not enough. Authorization policies, access controls, separation of duties, monitoring, and validation of the context of each transaction become equally important.
Ben-Natan drew a parallel with the attack on Bybit. The comparison, however, does not prove that the two incidents followed the same method. It serves as a warning about a broader risk: a key can remain in storage and still be used maliciously if the systems around it are compromised.
The main lesson is uncomfortable, but necessary. Blockchain security does not depend solely on the strength of cryptography. It depends on the entire operational chain that determines when, how, and why a transaction should be signed.
A private key does not operate in isolation like a vault. It is part of an infrastructure, and any vulnerable link can turn a legitimate authorization into a dangerous operation.
