Miasma Phantom Gyp: node-gyp spawning node index.js then bun executing tmp payload
Detects a suspicious execution chain where 'node-gyp' is observed spawning 'node' to execute 'index.js', characteristic of a 'Phantom Gyp' malicious pattern, followed immediately by the execution of a temporary JavaScript payload via the 'bun' runtime. This pattern is indicative of a multi-stage loader often used in supply chain attacks involving obfuscated payloads.
