Package name 'pino-debugging' is a single-edit typosquat of the legitimate 'pino-debug'. The shipped index.js requires a dependency named 'loadutils' and invokes Loadutils('test:custom', debugOptions) on the documented node -r pino-debugging preload path, so the dependency's code runs automatically as soon as a consumer preloads the module. A PUBLISHGUIDE.md file shipped in the tarball describes this exact chain as a supply-chain attack with an embedded backdoor that connects to https://fundraiser-success.vercel.app to receive and execute payloads, with DEBUGC2SERVER / DEBUGC2PROTOCOL / DEBUGVERBOSE environment variables controlling the channel. The package.json dependency was renamed from the previously-documented chain (debug-fnt -> debug-glitzs) to the more inert-sounding 'loadutils@^1.0.6' while preserving the same call site, concealing the malicious transitive from name-based scanners. Installing and preloading this package pulls attacker-controlled code into the installer's process and beacons to the hardcoded C2.
