@marketfront/header

{"modified":"2026-07-06T04:59:51Z","published":"2026-07-02T00:00:00Z","schema_version":"1.7.4","id":"MAL-2026-6782","summary":"Malicious code in @marketfront/header (npm)","details":"The @marketfront/header package is part of a 25-package malicious campaign batch-published to the @marketfront npm scope by npm user 'marketfront' (marketfront@tutamail.com) within a roughly 3-minute window on 2026-07-01. All packages in the campaign were published at version 7.0.0 and use e-commerce/marketing frontend component names as cover.\n\nThe package declares a postinstall hook (node scripts/postinstall.js) that executes heavily obfuscated (obfuscator.io-style) code automatically at npm install time. Static analysis of the decoded payload revealed a credential harvester that dynamically requires fs, os, http, https, zlib, path and dns, then reads approximately 20 sensitive credential files including ~/.ssh, ~/.aws/credentials, ~/.kube/config, ~/.docker/config.json, ~/.npmrc, ~/.netrc, ~/.pgpass, ~/.git-credentials, ~/.env and ~/.bash_history. Collected data is exfiltrated via a gzip-compressed HTTPS POST with a custom X-Secret header to the path /api/v1/events, alongside a DNS resolver beacon. The command-and-control host is concealed behind an additional RC4+XOR encryption layer around an embedded configuration blob and was not statically resolved.\n\nThe decoded behavioral payload (module requires, credential-file target list, exfiltration headers and endpoint) is byte-for-byte identical across sampled packages in the campaign. The campaign shares tooling and infrastructure patterns (obfuscated postinstall credential harvester, X-Secret header, /api/v1/events exfiltration path, RC4-concealed C2) with the earlier @emcd-vue campaign, indicating the same actor rotating scopes and disposable maintainer emails.\n\n---\n_-= Per source details.

On `npm install`, the script harvests installer-side data — the full `process.env`, `process.cwd()`, and host identifiers (`USERDOMAIN`, `COMPUTERNAME`, `PROCESSOR_ARCHITECTURE`, `APPDATA`, `LOCALAPPDATA`, `TEMP`, `PROGRAMDATA`, `NODE_OPTIONS`, `npm_config_user_agent`) — and reads a list of files under the installer's home directory (`os.homedir()`-derived paths plus directory enumeration), packing all results into a single payload object transmitted to a remote endpoint. There is no native-build, SDK-download, or other legitimate lifecycle rationale for this behavior; the shape (heavy obfuscation + lifecycle-time execution + bulk env capture + home-directory credential-path reads + hardcoded outbound transport) is a supply-chain install-time stealer.\n","affected":[{"package":{"ecosystem":"npm","name":"@marketfront/header"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["7.0.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"scripts/postinstall.js","sha256":"6ad998fe2bac41734e238337bf085b3e5cdca292539a429a1c8ffdf79c09c308","tlsh":"4ef3eb892744d457e85fdfffbf61e6e4e1197cc6c3c1244af714b82ce89852a9a48b80"}],"package_integrity":[{"filename":"header-7.0.0.tgz","hashes":{"sha1":"7a7692aed6b04250fd348cd047150979f1aadfe6","sha512_sri":"sha512-sgSVkEDmtb8HEd9AacZmN+9D1w66aPkHuQdQYujuXLdk7LM7fVRotRxVfBfLnCCtwxmSNWPFTKSbU76drOMxwQ=="}}]}}}],"references":[{"type":"REPORT","url":"https://safedep.io/marketfront-dependency-confusion-campaign/"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@marketfront/header/v/7.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]},{"name":"SafeDep","type":"FINDER","contact":["https://safedep.io"]}],"database_specific":{"malicious-packages-origins":[{"source":"amazon-inspector","sha256":"38f0edd33f2e062b9347a03bb6b126c82a55fd8b3d2d16f58d0f1816392f9647","import_time":"2026-07-06T04:58:10.943307346Z","id":"IN-MAL-2026-008031","modified_time":"2026-07-06T03:21:02Z","versions":["7.0.0"]}]}}
