{"id":"MAL-2026-10943","summary":"Malicious code in aftermathfi (npm)","details":"The aftermathfi package was published to the npm registry by user 'jet0010001' (maintainer email bremagml0002@gmail.com) as part of a dependency-confusion / reconnaissance campaign impersonating the Aftermath Finance SDK (Aftermath Finance is a DeFi protocol on the Sui blockchain). The package was published at version 99.0.0 - an inflated version number characteristic of dependency-confusion attacks, intended to cause a misconfigured resolver to prefer this public lookalike over the intended private/internal dependency of the same name.\n\nThe package declares a preinstall hook (\"node setup.js || true\") that executes automatically at npm install time, before any application code runs. The bundled setup.js performs host reconnaissance and credential harvesting: it collects the machine hostname, the current OS username, the current working directory, the contents of /etc/hostname, and the output of 'git remote -v', and it enumerates process environment variables whose names match the pattern /key|secret|token|pass|auth|private|drone|gitea|sui|admin|deploy/i - capturing API keys, secrets, tokens, passwords, and Sui/deploy/CI credentials. The collected data is serialized to JSON and exfiltrated via an HTTPS POST to the hardcoded attacker-controlled endpoint https://2.25.140.71:8443/aftermath/npm-dep-conf, with TLS certificate verification disabled (rejectUnauthorized: false) so a self-signed listener is accepted. Errors are silently swallowed so the install appears to succeed. The published module code (index.js) is a benign stub exporting only { version: \"99.0.0\" }, consistent with a package built solely to deliver the install-time beacon.\n\nThe install-time payload is byte-for-byte identical across the campaign's packages (aftermath-finance, aftermath-sui, aftermathfi), all published by the same maintainer within seconds of each other and all beaconing to the same collector.\n\n---\n_-= Per source details. Do not edit below this line.=-_\n\n## Source: amazon-inspector (556ad9b21010fc9541cf77cae90893323621b194137c16ea6e3bd67744366a51)\nThe package's preinstall script (setup.js) runs automatically during `npm install` and harvests installer-side data. It iterates process.env and filters keys matching credential-shaped patterns (key/secret/token/pass/auth/private/drone/gitea/sui/admin/deploy), and via execSync collects hostname, /etc/hostname, username, current working directory, and `git remote -v` output. The collected data is POSTed over HTTPS to the hardcoded bare-IP endpoint https://2.25.140.71:8443/aftermath/npm-dep-conf with TLS certificate validation disabled (rejectUnauthorized:false). The destination is not a documented first-party service, and the behavior fires unconditionally on install with no opt-in.\n","modified":"2026-07-28T14:37:19.281047399Z","published":"2026-07-20T00:00:00Z","database_specific":{"malicious-packages-origins":[{"modified_time":"2026-07-28T13:33:53Z","versions":["99.0.0"],"source":"amazon-inspector","sha256":"556ad9b21010fc9541cf77cae90893323621b194137c16ea6e3bd67744366a51","import_time":"2026-07-28T14:19:58.286986024Z","id":"IN-MAL-2026-010902"}]},"references":[{"type":"WEB","url":"https://www.npmjs.com/package/aftermathfi"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/aftermathfi/v/99.0.0"}],"affected":[{"package":{"name":"aftermathfi","ecosystem":"npm","purl":"pkg:npm/aftermathfi"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["99.0.0"],"database_specific":{"indicators":{"package_integrity":[{"filename":"aftermathfi-99.0.0.tgz","hashes":{"sha1":"a16c48837218d2ef827ca79acded21eb9e8b684a","sha512_sri":"sha512-nY9gzNaxRr21MZA4fdD/ojal+2h4ase2zvbYC9gkQMl63QEZ++qr3Nju6aXlUv64PUhuBoAxbuOSOq16vgmAeQ=="}}],"evidence_files":[{"path":"setup.js","sha256":"729b7aaaa8b18cc377bc350faa056e25d043001ab7a86a65207b2fe676a0d808","tlsh":"6b1154e093f0f3719ea595a4f04b900b5153d0077d5b7c60f69881651f8d65ca5b2ce6"}]},"iocs":{"urls":["https://2.25.140.71:8443/aftermath/npm-dep-conf"],"ips":["2.25.140.71"]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/aftermathfi/MAL-2026-10943.json","cwes":[{"name":"Embedded Malicious Code","cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature."},{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}]}}],"schema_version":"1.7.5","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"SafeDep","contact":["https://safedep.io"],"type":"FINDER"}]}
