MAL-2026-5970 Malicious code in cryptodao-types (npm)

On npm install, the package's postinstall script (recon.js) harvests installer-side secrets and POSTs them to attacker-controlled webhook endpoints. The script collects hostname, username, cwd, and roughly 40 named environment variables including AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, NPM_TOKEN, GITLAB_ACCESS_TOKEN, SSH_PRIVATE_KEY, PRIVATE_KEY, MNEMONIC, SEED_PHRASE, and DB_PASSWORD. It also reads .env and .env.production files from the current working directory, parent directories, /, /app, and /root, and enumerates /builds and gitlab-runner directories. The collected payload is then sent via HTTPS to webhook.site/d6d18927-e513-4df7-b019-58bfc64fe0dd and enqoojbegdvxj.x.pipedream.net with rejectUnauthorized: false to bypass TLS-inspecting corporate proxies. The package name combined with version 99.99.99 and the internal-sounding description is consistent with a dependency-confusion attack targeting an organization's internal CI builds.

The OpenSSF Package Analysis project identified 'cryptodao-types' @ 99.99.99 (npm) as malicious.

It is considered malicious because:

• The package communicates with a domain associated with malicious activity.
