The tme-error npm package, published by a malicious actor, impersonates an internal package namespace to exploit dependency confusion. It includes a preinstall hook that executes code during npm install, sending the installer's public IP, hostname, username, and runtime metadata to an attacker-controlled Sentry endpoint without user consent. This behavior enables reconnaissance on victims and potential data exfiltration. The package also silently redirects error reporting to the attacker's Sentry project if consumers call its init() function without specifying their own DSN. The affected version is 2.8.42. Removal alone may not fully remediate the compromise, and secrets should be rotated.
