npm/@ornikar/renovate-config is affected by the large-scale, self-propagating npm supply-chain worm of 2026-08-04 (the "Shai-Hulud: Here We Go Again" wave) — the same campaign that began with the compromise of the keyv and cacheable maintainer account. The listed version(s) were trojanized and republished by the worm after it reached an npm publish token belonging to a maintainer in this namespace; the payload enumerates every package a stolen token controls and republishes each with the same hook, so many packages under this scope were poisoned in the same short window. Every poisoned release adds a preinstall hook (`"preinstall": "node setup.mjs"`) that runs on a bare `npm install`, before any project code. setup.mjs downloads a standalone Bun runtime and runs a byte-identical, heavily obfuscated ~728 KB second-stage credential stealer (shipped as Math_Symbol.js / math_init.js). It harvests GitHub, npm, AWS, GCP, Azure, HashiCorp Vault and Kubernetes credentials plus generic secrets and private keys (TruffleHog-style sweep), reads CI/CD secrets and identifies build runners, then republishes further packages the stolen token can reach. Rather than a fixed command-and-control host, it exfiltrates stolen findings to attacker-created GitHub repositories (descriptions reading "Shai-Hulud: Here We Go Again") and over DNS. Treat any environment that installed an affected version (with install scripts enabled) as compromised: rotate and revoke all reachable credentials (npm and GitHub tokens, cloud keys, Vault/Kubernetes secrets, and CI org/repo secrets). Part of the August 2026 npm worm that poisoned 400+ packages across many organizations.

It downloads the Bun runtime (oven-sh/bun v1.3.13 release archive) from GitHub, extracts it, chmods it executable, and then invokes it via `execFileSync(bun, [math_init.js])` to run a bundled 727KB single-line JavaScript file whose identifiers and strings are heavily obfuscated (rotating string-array `WV8StW`, mangled globals). The package's declared purpose is sharing a JSON Renovate configuration; earlier releases (through 9.0.0) shipped only a `renovate-config` JSON block in package.json, with no preinstall hook, no setup.mjs, and no bundled JS payload. The alternate-runtime execution pattern (fetching Bun and using it to run the payload) also bypasses Node-level tooling that would otherwise observe the executed code. This is a hijacked or maliciously republished version delivering install-time arbitrary code execution on any machine that installs it.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
