Malicious code in gt-tester-exp-profiler-exp-00000017 (PyPI)
Details
**Severity:** Critical **Affected versions:** `= 1.0.0` ## Source: amazon-inspector (f1490f970bd52c80c89f33029f9e875f1fb595014621d50e0ce87a167d1cd348) setup.py installs a site-wide.pth file (gt_tester_exp_profiler_exp_00000017_probe.pth) into site-packages that imports the package's probe module and calls run_probe() at every Python interpreter startup. probe.py performs a plaintext HTTP GET to the bare IP 104.236.116.157 with a per-call random hex tag, fingerprinting the installer's machine to a third party on every Python invocation — not just when the package is explicitly imported. The User-Agent string claims an 'Academic research study' but no consent is obtained at install or runtime. Package metadata is a generic placeholder with no author, homepage, or publisher identification, and the destination is a bare IP not associated with any declared publisher. The.pth mechanism converts what would be an import-time call into persistent host beaconing across every CI job, virtualenv activation, and script execution on the machine. --- Credit: [OpenSSF](https://github.com/ossf/malicious-packages) ([source](https://github.com/ossf/malicious-packages/blob/49d0cfba3689ed9b195d101d3a2a964c6a77f767/osv/malicious/pypi/gt-tester-exp-profiler-exp-00000017/MAL-2026-4753.json)) **References:** - https://github.com/ossf/malicious-packages/blob/49d0cfba3689ed9b195d101d3a2a964c6a77f767/osv/malicious/pypi/gt-tester-exp-profiler-exp-00000017/MAL-2026-4753.json - https://pypi.org/project/gt-tester-exp-profiler-exp-00000017/1.0.0 - https://github.com/advisories/GHSA-4x29-879m-mpvj
