Hey everyone, I wanted to share my recent experience with securing my OpenHAB setup after a concerning incident. I hope this can help others stay vigilant and proactive in protecting their systems.
Earlier this week, I noticed some unusual activity on my OpenHAB server, which runs on a Raspberry Pi 4. It seemed like someone had gained unauthorized access and executed several commands with sudo privileges. The logs showed a series of commands that downloaded scripts, installed packages, and modified configurations, particularly affecting my Node-RED setup. While I’m still piecing together exactly how the breach occurred, I’ve taken immediate steps to secure my system.
First, I closed all unnecessary ports on my router to limit potential entry points. Next, I reviewed the cron jobs and system logs to ensure no lingering malicious processes. I also restored my Node-RED settings from a backup, as the attackers had altered the configuration files, which temporarily broke my flows. Thankfully, I had regular backups in place, which made the recovery process smoother.
Now, I’m focused on thoroughly scanning my system to ensure no remnants of the attack remain. My question to the community is: Does anyone know of a reliable antivirus solution or scanning method for OpenHAB systems? I’d like to be extra sure that everything is clean before resuming normal operations.
This incident has been a good reminder of the importance of security best practices, such as using strong passwords, limiting access, and keeping software up to date. I’m grateful for the resilience of my setup and the tools that allowed me to recover quickly. I’d love to hear any tips or experiences others have had in securing their OpenHAB installations.
Stay safe out there, and happy automating!
