Analysis of ttsflow 0.1.0 on PyPI did not surface any behavior indicating a supply-chain attack against installers. No install-time or import-time network activity, credential or filesystem harvesting, remote code fetch-and-execute, silent-relay, backdoor, or dependency-dropper pattern was identified in the package's shipped contents.

This campaign consists of similar loader packages, which provide executing code from a given URL. 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.

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Campaign: 2026-10-voice-synthesis-profiles

Reasons (based on the campaign):

  • other

  • Downloads and executes a remote malicious script.
