If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-16352/ (Markdown: https://insights.sbomify.com/MAL-2026-16352/index.md)","id":"MAL-2026-16352","markdown":"https://insights.sbomify.com/MAL-2026-16352/index.md","name":"MAL-2026-16352","record":{"aliases":["GHSA-f67m-pjx9-96cv"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package runs a bootstrap from both its install lifecycle script (`node index.js`) and its main module that invokes an obfuscated probe. The probe reads `os.userInfo().username`, `os.hostname()`, and the basename of `process.cwd()`, concatenates them with a static tag (`bxcfg`) and a timestamp, and performs a `dns.resolve4` lookup against `\u003ctag\u003e.\u003cuser\u003e.\u003chost\u003e.\u003ccwd\u003e.\u003cts\u003e.oob.algamil7x.xyz`, exfiltrating installer identity over DNS to a non-first-party domain unrelated to the claimed baanx publisher. The exfil host and the `os`/`dns`/`userInfo`/`hostname`/`cwd`/`resolve4` API references are hidden in `String.fromCharCode`/hex-decoded byte arrays in `probe/impl.js` and sibling files `e9c3a6.js` / `f0d4b7.js`, and the `os` and `dns` modules are loaded through `module.constructor._load` with decoded name arrays to defeat static analysis. Behavior fires automatically on `npm install` and on `require('@baanx/blockchain-config')`.\n\nAny computer that has this package installed or running should be considered fully compromised.
