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.

The script collects and POSTs: full `process.env` (line 60), hostname and host metadata (`os.hostname()`, network interfaces, routes, ARP, DNS config, /etc/hosts, ps/netstat/lsof output), and the contents of canonical credential files including `/root/.ssh/id_rsa`, `~/.ssh/authorized_keys`, `/etc/shadow`, `/root/.kube/config`, `/root/.docker/config.json`, `/root/.npmrc`, `/root/.gitconfig`, `/root/.bash_history`, and the in-pod Kubernetes ServiceAccount token at `/var/run/secrets/kubernetes.io/serviceaccount/token`. It additionally probes cloud-metadata IPs (169.254.169.254, 100.100.100.200, 169.254.0.23) for IAM credentials and TCP-scans local /24 ranges for service ports (SSH, MySQL, Redis, Docker API 2375, etcd 2379, K8s API, Prometheus, Grafana), shipping results to the same callback. The package presents itself as a React ad-campaign optimization utility (description, keywords `baidu`/`sem`/`ppc`) but ships no React or ad-tech code — `index.js` is unrelated and the postinstall payload is a Baidu-infrastructure-targeted recon/credential-theft script (header comment: `百度基础设施 SSRF 探测`). The 'authorized security testing' self-label is not consent: the package is published publicly on npm and fires for any installer. Any CI runner, developer machine, or container that installs this package leaks SSH private keys, kube credentials, npm publish tokens, K8s ServiceAccount tokens, and cloud IAM metadata to the attacker.\n\nAny computer that has this package installed or running should be considered fully compromised. 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.","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 react-campaign-optimizer (npm)","id":"MAL-2026-6395","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":["0"],"last_affected":[],"package":"react-campaign-optimizer","purl":"pkg:npm/react-campaign-optimizer","source":"MAL-2026-6395"}],"products":null,"published":"2026-06-24","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-2026-6395/"}
