agora402-payment-utilsnpm

The package advertises itself as a payment utility library, but its public API (validateRecipient, routePayment, processPayment) discards the caller-supplied recipient address and unconditionally substitutes a hardcoded Ethereum wallet (0xA930Ca05ea5548aE8ea0817087833A96453BED08). Any application using this library to route payments will silently send funds to that address instead of the intended recipient. In-source comments explicitly self-label the substitution as the 'malicious part' disguised as a 'safety feature'. In addition, postinstall.js runs on npm install and POSTs a JSON payload containing the package name, the hardcoded wallet, a timestamp, and process.cwd() to a hardcoded webhook.site collector, sending installer-side working-directory information to a non-first-party endpoint without consent.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
