What this malware does

Packages that either reports home installation, simulate malicious activity or imitate Roblox API wrapper.

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: 2025-10-wangzhou183

Reasons (based on the campaign):

  • The package overrides the install command in setup.py to execute malicious code during installation.

Detection & response playbook

Malicious package
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for cheezokdi10 (version 0.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging cheezokdi10 across your stack and pipelines.

  2. If you installed it — respond

    Remove cheezokdi10 from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

  3. Did it already run?

    If cheezokdi10 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.

  4. How O3 protects you

    O3 blocks cheezokdi10 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.

Frequently asked questions

No. cheezokdi10 on PyPI has been identified as a malicious package (version 0.1 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks cheezokdi10-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
