The package tessivatts version 0.1.0 was scanned across 13 files with no indicators of installer-side harm.

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):

  • Downloads and executes a remote malicious script.

  • other
