Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. 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-2026-17154/ (Markdown: https://insights.sbomify.com/MAL-2026-17154/index.md)","id":"MAL-2026-17154","markdown":"https://insights.sbomify.com/MAL-2026-17154/index.md","name":"MAL-2026-17154","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package's `install` lifecycle script runs `node index.js`, which loads `runtime/support/telemetry/probe/impl.js`. That module reads `os.userInfo().username`, `os.hostname()`, and `process.cwd()`, concatenates them with a fixed prefix `nfamh` and a timestamp into a single DNS label, and issues a `dns.resolve4` query against the hardcoded domain `oob.algamil7x.xyz`, exfiltrating installer identity over DNS on `npm install`. The same code path also fires on every `require()` of the package via the declared `main`. Destination domain, the loader targets `os`/`dns`, and the identifiers `userInfo`/`hostname`/`cwd`/`resolve4` are stored as charcode/hex arrays and reconstructed at runtime via `String.fromCharCode`, and the `os` and `dns` modules are pulled in through `module.constructor._load` rather than `require`, concealing the destination and API surface from static inspection. Comments frame the behavior as `registry connectivity diagnostics`, contradicting the actual dataflow.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in @nf-addons/am-global-header (npm)","id":"MAL-2026-17154","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":[],"last_affected":[],"package":"@nf-addons/am-global-header","purl":"pkg:npm/%40nf-addons/am-global-header","source":"MAL-2026-17154"}],"products":null,"published":"2026-09-24","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-17154/"}
