add-two-numbers-x7q9mnpm
add-two-numbers-x7q9m is a confirmed malicious npm package (MAL-2026-12032) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in add-two-numbers-x7q9m (npm)
What this malware does
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.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for add-two-numbers-x7q9m (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging add-two-numbers-x7q9m across your stack and pipelines.
If you installed it — respond
add-two-numbers-x7q9m is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If add-two-numbers-x7q9m was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks add-two-numbers-x7q9m before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
