Full analysis:	https://app.any.run/tasks/7395cad2-cd1b-4eb9-8875-94da1cf1ec97
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. Oyster (also seen in reporting as Broomstick or CleanUpLoader) is a Windows backdoor/loader actively used in multi-stage intrusion campaigns. Recent campaigns weaponize SEO-poisoning and malvertising to trick IT and dev users into downloading trojanized installers (PuTTY, WinSCP, Microsoft Teams, etc.), which then drop Oyster to establish a persistent foothold and load additional payloads (often leading to data theft or ransomware).
