NPM Package Malware Attack & LavaMoat Defense

A recent attack saw malicious code injected into the `is-arrayish` NPM package, aiming to steal ETH from user transactions. The malware achieved this by overriding browser functions like `fetch`, `XMLHttpRequest`, and `window.ethereum.request`. Instead of a detailed attack analysis, the article demonstrates how LavaMoat prevents such attacks. LavaMoat isolates each dependency's modules into separate lexical global contexts (Compartments), restricting access to globals and imports specified in a policy. This prevents malicious code from altering transaction addresses. Even sophisticated malware would struggle to bypass LavaMoat's defenses.
