Malicious code in sympy-dev (PyPI) Remove it immediately and rotate any exposed credentials.
What this malware does
Package downloads and executes code from remote servers, indicating malicious behavior. Multiple files and IPs involved. Package impersonates popular sympy package.

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 sympy-dev (4 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging sympy-dev across your stack and pipelines.
If you installed it — respond
sympy-dev is a typosquat — you almost certainly intended a legitimately-named package. Remove sympy-dev, 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 sympy-dev 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 sympy-dev 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.
