reactive-cdk-app@1.0.4

package.json declares `preinstall: node index.js`, so installation automatically executes index.js. The script reads /etc/passwd via fs.readFileSync, collects hostname, username, platform, cwd, and home directory from the os module, slices the first 30 entries of process.env (which on CI typically include AWS_*, GITHUB_TOKEN, NPM_TOKEN, and similar credentials), and HTTPS-POSTs the JSON payload to `3nrgzlqwix6erldow0s0kttsojuai36s.oastify.com` — a Burp Collaborator out-of-band exfiltration subdomain. The package name and description ('package of the reactive-cdk-app of the aws') impersonate AWS CDK naming, fitting a typosquat-with-payload pattern. Any developer or CI system running `npm install reactive-cdk-app` leaks host identity, the local user database, and a bulk slice of environment secrets to the attacker. ## Source: ghsa-malware (171cafb2d7e5b500dd92fe5d46da3a09b37ac9ff62af885241b41e8401746144) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it. ## Source: ossf-package-analysis (d01657e9ca5ae8e8f34576437bbc86bb276c83d99dfd1563da57fe880a6ac6fd) The OpenSSF Package Analysis project identified 'reactive-cdk-app' @ 1.0.1 (npm) as malicious.
