    Summary: Malicious code in @or-sdk/ccp (npm)

    Details: npm/@or-sdk/ccp 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. Source: amazon-inspector (e4f1662fce055d4e48c3bce162a3cf8dfcbca07595978575b2ba97cf752c8065) The npm package @or-sdk/[email protected] declares a preinstall script (`node setup.mjs`) that runs automatically on `npm install`. The setup.mjs script is itself obfuscated with obfuscator.io-style `_0xNNNNNN` identifiers and per-function inline string-lookup objects that hide plain strings such as 'musl', '/etc/os-release', 'Alpine', and '--version'. It downloads the Bun runtime binary from https://github.com/oven-sh/bun/releases/download/bun-v1.3.13/ into a temp directory, chmods it executable, and then invokes it via `execFileSync` to run a sibling 727KB file `math_init.js` shipped in the tarball. `math_init.js` carries a `@bun @bun-cjs` header followed by a heavily obfuscated bundle (string-array-shuffle `push(shift())` transform, opaque decoder tables, thousands of numeric constants) with no readable relationship to the package's stated CCP SDK purpose. Pulling a second-language runtime specifically to execute an obfuscated sibling bundle at install time is an alternate-runtime dropper pattern: it bypasses Node-only static analysis and hides the payload behind two obfuscation layers plus a runtime switch. The behavior fires on every default install of this version.

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.
