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\nThe package ships an obfuscated scripts/postinstall.js (RC4 + shuffled string-array obfuscation, NODE_OPTIONS/argv inspector-flag check, random startup delay) that npm runs automatically on install via package.json's `postinstall: node scripts/postinstall.js` hook. When executed, the decoded payload collects host identifiers (hostname, username, homedir, platform, npm_config_user_agent), Windows environment variables (USERDOMAIN, COMPUTERNAME, APPDATA, LOCALAPPDATA, TEMP, PROGRAMDATA), and reads installer-owned secret files the package never wrote — shell history (.bash_history,.zsh_history), ~/.ssh, ~/.aws, ~/.netrc, and browser profile directories — using readFileSync/readdirSync helpers over byte-array-decoded path strings. The collected data is JSON-serialized, XOR-encrypted, and transmitted over two channels: an HTTPS POST to a runtime-selected hostname, and a DNS-tunnel that base32-encodes the payload into subdomain labels resolved via node's `dns` module. The package is scoped `@marketfront/*` and presents itself as an internal HTTP client with fabricated corporate URLs (github.marketfront.io, jira.marketfront.io) and `private: false` — the classic dependency-confusion shape targeting an organization that uses that scope internally. No real library functionality is shipped; the package is a pure delivery vehicle for the postinstall payload.","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 @marketfront/basemarkettemplate (npm)","id":"MAL-2026-6767","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":"@marketfront/basemarkettemplate","purl":"pkg:npm/%40marketfront%2Fbasemarkettemplate","source":"MAL-2026-6767"}],"products":null,"published":"2026-07-02","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-2026-6767/"}
