matplotlibePyPI
Malicious code in matplotlibe (PyPI) Remove it immediately and rotate any exposed credentials.
What this malware does
Clearly typosquatting packages, but no known malicious parts.
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.

Detection & response playbook
TyposquatFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for matplotlibe (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 matplotlibe across your stack and pipelines.
If you installed it — respond
matplotlibe is a typosquat — you almost certainly intended a legitimately-named package. Remove matplotlibe, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If matplotlibe 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 matplotlibe 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 matplotlibe-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.
