OpenSSF/OSV advisory MAL-2026-7016 confirms this npm version as malicious. On `npm install`, the package's postinstall hook runs index.js, which performs an HTTPS GET to https://http-logger-production.up.railway.app/payload, base64-decodes the response body (Buffer.from(data.trim(), 'base64').toString('utf-8')), and passes the decoded string to child_process.execSync with { shell: '/bin/bash' }...

Summary
Malicious code in @vraksha/gh-helper (npm)
Details
On `npm install`, the package's postinstall hook runs index.js, which performs an HTTPS GET to https://http-logger-production.up.railway.app/payload, base64-decodes the response body (Buffer.from(data.trim(), 'base64').toString('utf-8')), and passes the decoded string to child_process.execSync with { shell: '/bin/bash' }. This is a fetch-decode-exec dropper: the executed content is attacker-controlled, mutable, and opaque, and it runs automatically at install time with the installer's privileges. No legitimate purpose (no shipped native source requiring a build, no vendor-matched SDK, no pinned artifact) justifies this pattern.
Decision reason
OpenSSF Malicious Packages via OSV confirms @vraksha/gh-helper@1.0.0 as malicious (MAL-2026-7016): Malicious code in @vraksha/gh-helper (npm)
