Description

Rapid7 has determined that users with JAVS Viewer v8.3.7 installed are at high risk and should take immediate action. This version contains a backdoored installer that allows attackers to gain full control of affected systems. **Completely re-imaging affected endpoints and resetting associated credentials is critical to ensure attackers have not persisted through backdoors or stolen credentials.** Users should install the latest version of JAVS Viewer (8.3.8 or higher) **after** re-imaging affected systems. These findings were identified through an investigation performed by Rapid7 analysts.
