@dbbhk/ui-components@99.0.0 declares both preinstall and postinstall hooks in package.json that execute `node callback.js`, so the payload runs automatically on `npm install`. callback.js queries the AWS instance metadata service at 169.254.169.254 for IAM role credentials, reads ECS task-role credentials via AWS_CONTAINER_CREDENTIALS_RELATIVE_URI, iterates process.env harvesting variables matching AWS/SECRET/KEY/TOKEN/PASSWORD/CREDENTIAL/AUTH/API/NPM/GITHUB/GITLAB patterns, and reads credential files including ~/.aws/credentials, /root/.aws/credentials, ~/.npmrc,.env,.npmrc, and the Kubernetes service-account token at /var/run/secrets/kubernetes.io/serviceaccount/token. It also collects host reconnaissance (hostname, whoami, id, platform, cwd, home directory, and CI-provider fingerprint for GitHub Actions/GitLab/Jenkins). Collected data is POSTed via https.request to api.telegram.org/bot<token>/sendMessage against a hardcoded Telegram bot and chat id 1064260758. The package name and scope impersonate an HSBC internal component (dependency-confusion shape with an implausibly high 99.0.0 version), and a header comment self-labels the file as an HSBC bug-bounty PoC; the code performs indiscriminate credential harvesting on any installer regardless of that framing.
