create-kachownpm
Malicious code in create-kachow (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
bin/create-kachow.js declares a BUILTIN_KEYS object containing live API keys for four third-party AI providers (Gemini key starting AIzaSyByPyGWXRVsa0..., OpenRouter sk-or-v1-673e3b6d..., Mistral OiCiNtvBsogE..., DeepSeek sk-7ecd4ed8...). The key-resolution helpers (e.g. resolveGeminiKeys) fall back to these built-in keys whenever the corresponding env var is unset, so any installer running npx create-kachow obtains and uses live credentials against generativelanguage.googleapis.com, openrouter.ai, api.mistral.ai, and api.deepseek.com. Two installer-affecting harms follow: (1) the keys are extractable from the package by anyone who installs it and can be abused against the four third-party providers (credential redistribution); (2) the README advertises a 'deterministic template generator — no AI required' fallback when no keys are set, but the code instead silently routes the user-supplied app description (the appPrompt from ask("Describe your app:")) to those four providers under the author's account, where prompts may be logged. This contradicts documented behavior and makes the data flow non-consensual.

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 create-kachow (version 1.2.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging create-kachow across your stack and pipelines.
If you installed it — respond
create-kachow 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 create-kachow 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 create-kachow 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.
