Summary
Malicious code in cryptodao-backend (npm)
Details
package.json declares `postinstall: node recon.js`, which auto-runs on `npm install`. recon.js (lines 30-46) scrapes a curated list of credential-bearing environment variables including AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, NPM_TOKEN, CI_REGISTRY_PASSWORD, GITLAB_ACCESS_TOKEN, SSH_PRIVATE_KEY, PRIVATE_KEY, MNEMONIC, and DB_PASSWORD. It additionally enumerates and reads.env files at multiple paths outside the package's own scope (`.env`, `../.env`, `/app/.env`, `/home/gitlab-runner/.env`, `/root/.env`), filtering lines matching /KEY|SECRET|TOKEN|PASS|PRIVATE|MNEMONIC/i. The collected JSON payload is POSTed (recon.js:84-87, 99-106) over HTTPS with `rejectUnauthorized:false` to two attacker-controlled endpoints: `https://webhook.site/d6d18927-e513-4df7-b019-58bfc64fe0dd` and `https://enqoojbegdvxj.x.pipedream.net/`. The package self-describes as the "CryptoDAO internal cryptodao-backend module" and is published at version 99.99.99 — the canonical dependency-confusion shape designed to outrank a private internal package of the same name during npm resolution. A source comment in recon.js explicitly labels itself a "Dependency Confusion Reconnaissance Payload."
