melcuratts 0.1.0 contains no observed install-time or import-time execution of attacker-controlled code, no credential or environment harvesting, no outbound network to attacker-controlled destinations, no silent relay of caller-supplied data, no persistence or backdoor mechanism, and no shipped third-party credentials. No supply-chain attack fingerprint is present in the package 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):

  • Downloads and executes a remote malicious script.

  • other
