The package bundles the legitimate resolve source and test fixtures to appear functional while hiding a credential-theft payload in `index1.js`, executed at install time via the `postinstall` script. It is part of a campaign that also includes `briantreehttp`, `dit-envv`, and `haswons`, all sharing an identical payload and C2 infrastructure.\n\nThe payload collects hostname, platform, architecture, Node.js version, UID, current working directory, all environment variables, AWS credentials (`~/.aws/credentials`, `~/.aws/config`), npm tokens from `.npmrc` files (root, home, and working directory), Docker config (`~/.docker/config.json`), git config, `.netrc`, yarn config, npm global config, directory listings of the working directory, home, filesystem root, and `/etc`, network configuration files (`/etc/resolv.conf`, `/etc/hosts`, `/proc/net/route`), and AWS ECS/EC2 instance metadata from internal endpoints. All collected data is base64-encoded and exfiltrated via HTTPS POST to `reportviewer.click/collect/`. A secondary DNS-based exfiltration channel encodes environment variables into a subdomain and issues a request to `dns.reportviewer.click`.\n\n---\n_-= Per source details.
