Verdict: Malicious activity
Threats:

A backdoor is a type of cybersecurity threat that allows attackers to secretly compromise a system and conduct malicious activities, such as stealing data and modifying files. Backdoors can be difficult to detect, as they often use legitimate system applications to evade defense mechanisms. Threat actors often utilize special malware, such as PlugX, to establish backdoors on target devices.
