Details

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

Source: kam193 (6f2ecdbc9e024d6dc51c8e5d48941c5aac432db65ad733317aed159d480973cd)

During installation or import, package silently adds a new authorized SSH key. It's closely related to the 2026-05-ninja-core-utils campaign, but there is no built-in crypto exfiltration.

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

Campaign: 2026-05-ninja-ssh-proto

Reasons (based on the campaign):

backdoor
obfuscation

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.
