QSnatch Technical Report

In October 2019, SecurityScorecard’s Threat Intelligence team discovered QSnatch, a malware targeting Quality Network Appliance Provider (QNAP) Network Attached Storage (NAS) systems. A NAS is a dedicated file storage server providing data access to heterogeneous clients. A business might use such a server for storing the data in a single place and providing access to the data to its employees, clients, partners. The NAS provided by QNAP Systems, Inc. runs a Linux-based operating system called QTS.

This report details a technical analysis of the malware, details of the discovery, a timeline of QSnatch’s history, and data and indicators of compromise (IoC) about the infected systems.
