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. WarmCookie is a backdoor malware that cyber attackers use to gain initial access to targeted systems. It is often distributed through phishing emails, frequently using job recruitment lures to entice victims into downloading and executing the malware. Malware Trends Tracker >>>
