Details

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

Source: kam193 (11f4beddcb42e2348d31d2ef0605d72198a28e796467c8afbac5c5c30d870315)

Clone of a legitimate Pydantic package with the added downloading of a remote code. The remote code is delivered from the GitHub repository and unpacked as a new module and then called during initialization of any models (runner injected into cloned Pydantic code). During analysis, the remote code was just a placeholder.

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

Campaign: 2026-11-pyprig

Reasons (based on the campaign):

  • Downloads and executes a remote malicious script.

  • clones-real-package
