Summary

Malicious code in amigapythonupdater (PyPI)

Details

-= Per source details. Do not edit below this line.=-

Source: kam193 (46cf32631436ddacf36a4984b254c10554b4e94c6099c5012a96ec3a7c5426a1)

During import, only in specific environments, a module containing code disguised as telemetry is imported. This code then exfiltrates sensitive environment variables and cloud tokens to a hardcoded location, as well as starts a job listening for commands to execute. Likely dependency confusion attempts

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

Campaign: 2026-02-amigapythonupdater

Reasons (based on the campaign):

exfiltration-generic
exfiltration-env-variables
The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.
dependency-confusion

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
