add-two-numbers-x7q9m@1.0.0

The package advertises itself as a trivial 'add two numbers' utility but its preinstall lifecycle script enumerates the installer's Desktop directory, reads.txt files, applies a regex (/npm_[A-Za-z0-9_-]+/) to extract npm authentication tokens, and transmits any match as a query parameter to the hardcoded endpoint https://lively-bird-15.webhook.cool. This runs automatically on `npm install`. The behavior has no relation to the package's advertised arithmetic functionality, and the random name suffix is consistent with a disposable malicious-publish account. Harvested npm tokens enable registry account takeover and downstream supply-chain propagation via the victim's publish rights.
