Binance earlier released an official post-mortem of the theft incident, disclosing the attack path, loss details, and timeline. The attack chain of the approximately $6.34 billion hack spanned about 4 to 5 months. In June, a wallet operations engineer downloaded a tampered Homebrew installation package while searching for AI programming tools. In September, another engineer encountered a fake interview invitation on a recruitment platform and was compromised after bypassing endpoint protection to download a "homework" file. The hackers subsequently used internal AI tools for lateral movement, obtained a container deployment token, and ultimately reached the wallet signing service.
Once the post-mortem was released, the crypto community quickly split into two camps. One camp believes Binance made obvious mistakes in security architecture, key management, or incident response, constituting avoidable negligence; the other camp emphasizes that in the face of highly sophisticated APTs, supply chain poisoning, and social engineering, such incidents are essentially impossible to prevent, and the responsibility lies more with the attackers than the platform.
SlowMist founder Cos, whose position is closer to "impossible to prevent," stated in a post that the theft process disclosed by Binance was an advanced persistent threat (APT) attack and cannot be understood merely as engineer operational errors or excessive permissions. Such attacks may chain together intelligence reconnaissance, social engineering, malicious code detection evasion, trust chain exploitation, lateral poisoning, cloud environment penetration, and risk control bypass, and may also involve zero-day exploits. The initial social engineering was only one link in the attack chain; a seemingly simple tactic can also cause serious consequences in a specific environment.
CoinEx founder Yang Haipo offered three technical criticisms of "avoidability":
First, the production environment was not isolated: machines with production permissions should not install third-party software or chat tools, nor should they be used for browsing and downloading interview assignments; they should be dedicated production machines. If development and operations environments are not strictly separated, they become attack entry points.
Second, the operations stack lacked meaningful 2FA: if a single key can complete critical operations, there is effectively no real second gate. A more robust approach would be hardware keys, Session Manager, and other mandatory session controls.
Third, MPC multi-signature was "nominal": there are multiple signers in name, but if the signers cannot independently verify the original transaction intent, compromising one node could bring down the entire mechanism. In his view, if Binance had solidly implemented environment isolation, least privilege, and independent verification, such attack entry points could have been greatly reduced.
OKX CEO Star approached the issue from "whether multi-layered defense in depth matches its name," arguing that the response downplayed platform responsibility and attempted to justify its own failures by disparaging the security of traditional banks. Star said Binance repeatedly emphasized that "only 2% of funds flowed out," but this figure does not address concerns about platform security. He also questioned Binance for continuing to attract new deposits through marketing campaigns during the crisis, and pointed out that crypto platforms and traditional banks face different threats, attack surfaces, and potential consequences; comparing the security of the two without that context is misleading. Star believes the incident may damage the crypto industry's credibility in the eyes of traditional capital markets, institutional investors, and regulators, and also casts doubt on Binance's claimed "multi-layered security defense."
Security auditor pashov believes that Binance developers could have blocked the attacker's entry point, and the platform's operational discipline needs improvement. He pointed out. Any software installed on a Mac must be downloaded from official sources and the source verified multiple times; work computers must never be used for interviews; if interview code must be run, it must be executed in a sandbox environment, not directly on machines with production access. Simple, boring discipline, once strictly enforced, can significantly reduce the attack success rate.
Crypto investor blanker said that after reading Binance's post-mortem, it still feels "a bit too amateurish." Mandatory bastion hosts for all staff, dynamic MFA, and mandatory screen locking when leaving one's seat should be standard for trading platforms. Binance's basic security hygiene could have been stricter, and this incident was not unavoidable.
Former PayPal President David Marcus believes the Binance attack is an operational security issue, not a failure of cryptography or the chain itself. After platforms accelerated settlement speeds, old security models can no longer keep up with current demands.
Dragonfly partner Haseeb Qureshi believes crypto platform infrastructure design should assume "it will be breached" by default, with 24/7 AI monitoring and a real "one-click shutdown" emergency switch to avoid scrambling when an incident occurs.
Telaga Charity founder ashen listed multiple questions: engineers actually used work computers to participate in job interviews, arbitrarily installed software on devices that could reach trading platform keys and permissions, the attack was not directly breached by AI, no virtual machine isolation was seen, and joked "better to replace people with AI to have less social engineering." He believes that one infected computer could affect billions of dollars in hot wallets, indicating flaws in permission isolation and device control themselves, and should raise alarm as to why there were no hardware keys, dedicated machines, or remote virtual machines with copy disabled.
