Qilin n'est pas un groupe de pirates informatiques, mais une "franchise" qui permet d'utiliser ses services contre rémunération. Apparue en 2022, elle reste nimbée de mystère. Des lycées du nord de la France aux mairies des Pyrénées-Orientales, un nom revient avec inquiétude : Qilin. Ce mot désigne un animal mythologique asiatique, mais c'est aussi le nom choisi par les concepteurs d'un logiciel malveillant qui paralyse 80% des lycées publics des Hauts-de-France(Nouvelle fenêtre) depuis le 10 octobre.
Analysis Summary
# Tool/Technique: Qilin Ransomware
## Overview
Qilin is a Ransomware-as-a-Service (RaaS) operation, described as a "franchise" that allows affiliates to use its services for a fee.
