This technical analysis details a malicious email campaign from September 2026 that distributes a backdoor via a customized ScreenConnect installer. The attack begins with a phishing email impersonating the Social Security Administration, claiming that a monthly electronic statement is available for download. Users who click the link are directed to a spoofed government website which prompts the download of a malicious executable.
Technical artifacts include a PE32 executable that establishes remote access through the ScreenConnect platform. Post-infection traffic analysis shows the malware communicating with specific relay servers and IP addresses to facilitate unauthorized control of the victim's machine. This incident highlights the ongoing trend of attackers utilizing legitimate remote desktop tools to maintain persistence and bypass security detections.
