: An employee searches for their company’s staff portal. They land on a compromised website that looks legitimate or offers a "download" for the portal access.
: Once the script confirms it is running on a real workstation (and not a virtual machine used by researchers), it downloads additional malware, such as Gootloader , Cobalt Strike , or ransomware. Key Characteristics File Type : .RAR (WinRAR compressed archive).
: If you encounter a search result leading to a Staffportal.rar download, report the URL to your organization's security team immediately.
: The user downloads Staffportal.rar . Inside this compressed file is typically a highly obfuscated JavaScript (.js) file.
: Only download company software or access portals via official links provided by your IT department or bookmarks you know are safe.
: If the user double-clicks the JavaScript file, it executes using the Windows Script Host. It does not open a portal; instead, it runs a script that gathers system information and reaches out to a Command and Control (C2) server.
