sympy-dev has 4 versions on PyPI flagged in 1 incident we track. Other versions of this package are not implicated - only the exact versions listed below were named by the source advisories.
Check what you actually have installed with pip show sympy-dev.
A PyPI typosquat of SymPy was published by the account "Nanit" across four versions on Jan 17, 2026. It fetches a remote JSON config, downloads an ELF, and executes it from a memfd to evade disk-based detection. The payload is XMRig mining Monero on infected developer workstations.
Versions named here: 1.2.3, 1.2.4, 1.2.5, 1.2.6
Treat the machine as compromised rather than simply upgrading. Packages in these incidents typically execute at install time, so the payload has already run with whatever credentials were in the environment.
sympy-dev is one of many packages in these incidents, and it is usually pulled in as a transitive dependency rather than one you installed directly. Paste your requirements.txt to check every dependency at once - it runs in your browser and nothing is uploaded.
Version data comes from the public advisories cited on each incident page. We list only versions those advisories name - we don't infer additional ones. Think this is wrong or incomplete? Tell us.
