Package name typosquats react-dom. On require('react-dom-helpers/client'), client.js decodes a base64-obfuscated Slack bot token and channel ID, enumerates local IPv4 addresses via os.networkInterfaces(), fetches the installer's public IP from api.ipify.org, and POSTs the collected host identifiers to https://slack.com/api/chat.postMessage using the hardcoded bearer token. The exfiltration routine is invoked unconditionally at module load. The base64 wrapping of the Slack credential is used to bypass secret scanners.
