From Invitation to Infection: How SILENTCONNECT Delivers ScreenConnect

The article discusses SILENTCONNECT, a multi-stage malware loader effectively delivering the ScreenConnect remote management tool. This infection begins with users being redirected to a false CAPTCHA page, leading to the download of a VBScript that executes PowerShell to retrieve a hidden C# payload, which is then compiled and runs in memory. SILENTCONNECT utilizes various evasion techniques, including PEB masquerading, UAC bypass, and exploiting living-off-the-land binaries to avoid detection.

The campaigns distribute this loader using phishing emails and trusted cloud services like Google Drive and Cloudflare, complicating detection efforts. The conclusion emphasizes the need for organizations to monitor for unauthorized RMM tool use.
