@rafaelsene01/agent-flownpm
Malicious code in @rafaelsene01/agent-flow (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
The package's main and bin entry, dist/agent-flow.js, is shipped as a heavily obfuscated bundle produced by javascript-obfuscator (declared as a devDependency in package.json). After deobfuscation, the runtime behavior matches the advertised purpose: a local Express server bound to 127.0.0.1:5522 that talks to api.github.com using the user-provided GH_TOKEN/GITHUB_TOKEN environment variable (or the local gh auth token output), manages git worktrees, and spawns the local claude CLI. No remote code fetch, no eval of remote content, no read of installer secret paths (~/.aws, ~/.ssh, ~/.netrc, ~/.npmrc), and no exfiltration destination beyond api.github.com. The postinstall hook only runs npm install --prefix web when web/package.json exists, which it does not in the published tarball. Obfuscating an MIT-licensed distributed bundle is a code-review-hostility concern rather than a supply-chain attack, but it materially raises the cost of independent verification and warrants human review.
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.

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 @rafaelsene01/agent-flow (17 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @rafaelsene01/agent-flow across your stack and pipelines.
If you installed it — respond
@rafaelsene01/agent-flow 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 @rafaelsene01/agent-flow 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 @rafaelsene01/agent-flow 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.
