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\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.","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 aftermathfi (npm)","id":"MAL-2026-10943","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":"aftermathfi","purl":"pkg:npm/aftermathfi","source":"MAL-2026-10943"}],"products":null,"published":"2026-07-20","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-2026-10943/"}
