    Details: Source: kam193 (6010189e23e54782200df770b6e40ed7e37284779c25f28cd145aadd9ee8b623) Package clones a legitimate library and adds a hidden code that downloads a malicious script. The script then downloads an archive with malicious executable in the version appropriate to the system architecture, and ensures persistency by adding automatically started service entries. The remote code is a Go-based inforstealer and backdoor previously attributed to Nordkorean cybercrime activities. The malicious code was introduced in version 0.1.1. Besides an infostealer, the package modifies the cloned Bittensor library to collect keys. Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2026-01-gztensor-cli Reasons (based on the campaign): - crypto-related - action-hidden-in-lib-usage - Downloads and executes a remote executable. - clones-real-package - peristence-autorun - typosquatting - obfuscation - backdoor - infostealer
