Initial findings point to a compromised DevOps engineer's laptop, which led to access to a service container and unauthorized withdrawal transactions. Binance found no evidence of a leaked private key. TRM Labs reports the Ethereum attack used 50 signed authorizations covering consecutive nonces via EIP-7702, and the delegation allowed six more sweeps over three and a half hours. About $3 billion was frozen with partners' help. The piece links this to recent supply-chain attacks via Nx packages, a trojanized Nx Console extension, swapped OVHcloud CLI binaries, and a trojanized Claude Code extension, all of which compromised developer machines. ## Full article daily.dev links to this article rather than hosting it.

Binance estimates approximately $6.3 billion in assets were affected. Its preliminary investigation points to a compromised DevOps engineer's laptop that led to access to a service container, from which the attacker submitted unauthorized withdrawal transactions. Binance found no evidence that a wallet private key itself was leaked, and about $3 billion was later frozen with partners' help. _Teams hardening developer laptops against supply chain compromise can track incident breakdowns like this on daily.dev._ ### What is EIP-7702 and how was it used in the Binance Ethereum hack? EIP-7702 is an Ethereum feature letting an account delegate execution to smart contract code, but it requires a valid authorization from the account itself. In the Binance incident, the attacker obtained 50 signed authorizations covering consecutive nonces, and once one matched the wallet's counter, a delegation to an attacker-controlled contract swept funds, remaining active for six more sweeps over three and a half hours. _Developers evaluating EIP-7702 risk for wallet infrastructure can follow analysis like this on daily.dev._ ### What happened in the Nx Console VS Code extension supply chain attack? A compromised release of Nx Console version 18.95.0 fetched and executed a credential-stealing payload from an orphan commit in the official Nx repository when a workspace was opened. The malicious version was available for about 11 minutes but also installed a persistent Python backdoor on macOS, so its impact outlasted that short publishing window. _Developers auditing IDE extensions for supply chain risk can track incidents like this on daily.dev._ --- Tags: [#security](https://daily.dev/tags/security), [#crypto](https://daily.dev/tags/crypto), [#npm](https://daily.dev/tags/npm) [View this post on daily.dev](https://daily.dev/posts/binance-s-6-3-billion-hack-puts-developer-machine-security-in-focus-w8iboratw) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Binance’s $6.3 Billion Hack Puts Developer Machine Security in Focus","url":"https://daily.dev/posts/binance-s-6-3-billion-hack-puts-developer-machine-security-in-focus-w8iboratw","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/binance-s-6-3-billion-hack-puts-developer-machine-security-in-focus-w8iboratw"},"datePublished":"2026-10-30T22:19:02.735Z","dateModified":"2026-10-31T01:24:50.943Z","description":"Binance estimates its October 29 security incident affected about $6.3 billion in assets.
