The beacon fires automatically on `pip install` and again on every `import calcboxlite`, so consumers in sandboxed builds, CI runners, REPLs, or downstream libraries all transmit installer identity to the endpoint. The destination host is unrelated to any advertised calculator functionality and is characteristic of an out-of-band interaction collector used for identifying vulnerable installers.\n","affected":[{"package":{"ecosystem":"PyPI","name":"CalcBoxLite"},"versions":["1.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"setup.py","sha256":"ee2f2e437ec1aa2857d526b01c2c8672a374d684892cd8efd58227c1a34efb5f","tlsh":"37f00287d8226433f5cb50d848a06fb07220b5137d029ca538dc23551fc84bad0b0958"},{"path":"calcboxlite/__init__.py","sha256":"bf1bde645d876a9bfb9dd447a30ae01af549e1fc68383922f6d6bb5bbb97758e","tlsh":"e101c0cbfc526413e7cf505840b5c6b072283d0768055879bcec53a61f84caae1b059c"}],"package_integrity":[{"filename":"calcboxlite-1.0.0-py3-none-any.whl","hashes":{"blake2b_256":"32ea3b7167a87d699d831042029ac6decae301b77610d087f9ef3d8f6875d6fb","md5":"2aa6621864b74e29dd17688251b91ee3","sha256":"91c7b84867cbf9d32086eb243829f6fc51e6de751ad3e9512fb6fb2df2a1086c"}},{"filename":"calcboxlite-1.0.tar.gz","hashes":{"blake2b_256":"4756870ba2ed4f76fa798db8008000cff616930052d60ac3880b36368d5598df","md5":"6fc929e0abc0baa398813d5e6796d6c5","sha256":"daae95ad04f5ec2d90751a222ef8f700119bf78ada9a0715938579e63a7c555a"}}]}}}],"references":[{"type":"PACKAGE","url":"https://pypi.org/project/CalcBoxLite/1.0/"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-018816","import_time":"2026-08-28T19:33:50.759180646Z","modified_time":"2026-08-28T17:02:12Z","sha256":"227fe04d85516bd5348dea2c0c25078d057eacb4f439fd6a241ea0409b7afd09","source":"amazon-inspector","versions":["1.0"]}]}}
