    Summary: Malicious code in react-dom-helpers (npm)

    Details: Source: amazon-inspector (2fae606be0dbd7c79552511c2553ec9e1d081df1279f0bc85502a6c08c0f17fb) 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.
