VENOMOUS#HELPER Phishing Campaign: A Wake-Up Call for RMM Tool Security
Since April 2025, a sophisticated phishing campaign named VENOMOUS#HELPER has targeted over 80 organizations, primarily in the U.S. Attackers impersonated the U.S. Social Security Administration, sending emails that directed recipients to download malicious executables disguised as official documents. These executables installed legitimate Remote Monitoring and Management (RMM) tools—SimpleHelp and ScreenConnect—on victims' systems, granting attackers persistent remote access. The use of these legitimate tools allowed the attackers to evade detection by standard security measures.

The dual deployment of RMM tools highlights the need for organizations to scrutinize the use of such software and implement robust monitoring to detect unauthorized installations.
