While they do not contain the malicious payload and the usage remains unknown, they are clearly a coordinated campaign to place multiple deceptive ways to load malicious code.\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\nCampaign: 2026-10-voice-synthesis-profiles\n\nReasons (based on the campaign):\n\n - Downloads and executes a remote malicious script.\n\n - other\n\nJudge assessment: The package implements a remote code loader: on import, `load()` fetches an arbitrary Python script from a caller-supplied URL, writes it to disk under a temp cache directory, and executes it in-process via `exec(compile(src, ...))`. The example URL baked into the docstring (`https://example/serve/eval-profile.py`) is classified as a C2 endpoint by the IOC classifier. The mechanism is generic by design — the actual malicious payload lives server-side behind the profile URL, making the package itself appear clean to static scanners while enabling arbitrary code execution at runtime. The attacker model is a supply-chain loader: a downstream package or user is socially engineered into calling `run(url=\u003cattacker-controlled-url\u003e)`, at which point any credential theft, persistence, or exfiltration payload can be deployed. The OSV advisory confirms this is part of a coordinated campaign of similar loader packages under the 2026-10-voice-synthesis-profiles campaign.\n\nENTRY\n  zennittts/__init__.py (module-import: 58)\n\nDESTINATION\n  - 1 fetched-payload (urls)\n  (values recorded in verified_iocs)\n\nEXFIL\n  - Network Request in zennittts/__init__.py: \"urllib.request.urlopen(\"\n\nADDITIONAL FINDINGS\n  - Dynamic Code Execution in zennittts/__init__.py: \"compile(src, mod.__file__, \"exec\")\"\n\nPAYLOAD FILES\n  zennittts/__init__.py","supportingMedia":null}],"references":[{"url":"https://opensourcemalware.com/threats/fcc6e5d7-f382-4c70-baac-bd6be4fc20fd","name":"Malicious pypi package: zennittts","tags":["advisory"]},{"url":"https://osv.dev/vulnerability/MAL-2026-18151","name":"","tags":["advisory"]},{"url":"https://pypi.org/zennittts","name":"","tags":["vendor"]}],"metrics":[{"format":"CVSS_V3","scenarios":null,"cvssV2_0":null,"cvssV3_0":null,"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","baseScore":9.6,"baseSeverity":"CRITICAL"},"cvssV4_0":null,"other":null}],"problemTypes":[{"descriptions":[{"lang":"en","description":"Embedded Malicious Code","cweId":"CWE-506","type":"CWE"}]}],"affected":[{"vendor":"unknown","product":"zennittts","collectionURL":"https://pypi.org","packageName":"zennittts","repo":"","defaultStatus":"affected","versions":[{"version":"all","status":"affected","versionType":"","lessThan":"","lessThanOrEqual":"","changes":null}],"cpes":null,"modules":null,"programFiles":null,"platforms":null}],"cpeApplicability":null,"rejectedReasons":null,"replacedBy":null,"x_vulnetix_aliases":{"direct":["MAL-2026-18151"]}},"adp":null}}
