Summary

Malicious code in aliyun-python-sdk-v2 (PyPI)

Details

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

Source: kam193 (29bd2455a576643c51939bd166abab847afd04c3142b576e3f9f0c7978763181)

Series of packages impersonating Alibaba Cloud. Two oldest hide code to run obfuscated code, but are likely to be used as dependency as the obfuscated code is not inside. The newest describe similar functionality, but the inside is highly obfuscated. Package names closely reassemble names of real Alibaba packages

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

Campaign: 2026-02-alibabacloude

Reasons (based on the campaign):

typosquatting
impersonation
obfuscation

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.
