Summary
Malicious code in stripe-internal-utils (npm)
Details

-= Per source details. Do not edit below this line.=-

package.json declares a postinstall hook that auto-fires on npm install and performs reconnaissance + exfiltration against the installer. The inline node -e payload fetches the installer's public IP from api.ipify.org, executes id || ver && whoami && hostname via child_process.exec, and POSTs a JSON body containing the timestamp, USERDOMAIN/USERDNSDOMAIN/COMPANY environment variables, public IP, hostname, current working directory, and shell command output to a hardcoded interactsh beacon at lszakfghwnvxspyfcmaabd1css99rnq3w.oast.fun over HTTP. The package's own description self-identifies as 'Full RCE PoC -osama', and the package name impersonates the Stripe brand to lure installers into a name they would plausibly trust. Any developer or build system running npm install stripe-internal-utils leaks identifying host and user information to the attacker.
