o3forms@99.1.99

Summary

The package name impersonates the OpenMRS O3 forms ecosystem (legitimate packages are published under the @openmrs/ scope). package.json declares an optionalDependency o3forms-utils resolved as github:core-modules-lab/o3forms-utils#76c1c55 — code fetched directly from GitHub, outside npm registry scanning. index.js (lines 1-4) wraps require('o3forms-utils') in a try/catch that silently swallows errors, so the off-registry payload executes on every consumer import with no visible failure if anything goes wrong. The package.json bin field maps 11 ubiquitous dev-tool names (webpack, vite, eslint, tsc, next, jest, prettier, nodemon, turbo, ts-node, webpack-cli) all to index.js, so any hoisted invocation of those commands (e.g. npx webpack) launches this package's loader and triggers the GitHub fetch+execute. Additional attacker-hygiene tells: version 99.1.99 (version-squat to outrank legitimate releases), config.unsafe-perm: true to keep root during npm scripts, and a placeholder OpenMRS Community Contributor author with no homepage. Installing or loading this package — or running any of the hijacked dev-tool commands in a project where it is hoisted — executes attacker-controlled code from a mutable GitHub commit.
