{"id":"MAL-2026-6766","summary":"Malicious code in @marketfront/baobabtech (npm)","details":"The @marketfront/baobabtech 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 real installer machines it assembles a payload containing the full `process.env`, os.platform/arch/release, os.userInfo(), os.networkInterfaces(), hostname, cwd, npm user-agent, and Windows environment variables (USERDOMAIN, COMPUTERNAME, PROCESSOR_ARCHITECTURE, PROGRAMDATA, APPDATA, LOCALAPPDATA, TEMP), then reads arbitrary files from directories chosen by decoded strings (including key=value parsing consistent with `.npmrc`-style credential stores) and attaches their contents to the same payload before sending it out. The package advertises itself as a database utility; none of that purpose requires whole-environment dumps, host fingerprinting, or arbitrary filesystem reads. This is an install-time credential and environment stealer.\n","modified":"2026-07-06T05:16:47.628266021Z","published":"2026-07-02T00:00:00Z","database_specific":{"malicious-packages-origins":[{"versions":["7.0.0"],"modified_time":"2026-07-06T03:19:35Z","id":"IN-MAL-2026-008021","import_time":"2026-07-06T04:58:10.483074138Z","sha256":"48c6526eab024e5b90615b3480f498d99f768b741191ea5e70d0f72ebabf139e","source":"amazon-inspector"}]},"references":[{"type":"REPORT","url":"https://safedep.io/marketfront-dependency-confusion-campaign/"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@marketfront/baobabtech/v/7.0.0"}],"affected":[{"package":{"name":"@marketfront/baobabtech","ecosystem":"npm","purl":"pkg:npm/%40marketfront%2Fbaobabtech"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["7.0.0"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@marketfront/baobabtech/MAL-2026-6766.json","indicators":{"package_integrity":[{"filename":"baobabtech-7.0.0.tgz","hashes":{"sha512_sri":"sha512-eLIGrLFwpPLOYKa76BcIRvl0j/R6KN+18JvC5NLUo2+LTKtip9/zx2ir+VS5xk6eD59NkARbStPmAdXQxscrLA==","sha1":"2e74bc45310341f16fe4474dbe3041c80455aa60"}}],"evidence_files":[{"tlsh":"baf3ec892740d446d89fdfff7f61e6f0e11a7cc6c3c1284af714b86ce89852a9a58781","sha256":"f3a4f644e2c817bce808d48b1b24209b22657cd9bd5599619466d9e2d430ca86","path":"scripts/postinstall.js"}]},"cwes":[{"name":"Embedded Malicious Code","description":"The product contains code that appears to be malicious in nature.","cweId":"CWE-506"},{"name":"Embedded Malicious Code","cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature."}]}}],"schema_version":"1.7.5","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"SafeDep","contact":["https://safedep.io"],"type":"FINDER"}]}
