It looks like there’s another round of Mikrotik RouterOS vulnerabilities out there. Given this, we strongly encourage everyone to update their Mikrotik devices to the latest releases of RouterOS at the Mikrotik downloads page.
This is especially if your router is connected to the Internet.
Additionally if you’re not using Winbox, it might be a good idea to disable the Winbox service.
See this article for more info. The article contains some pointers about where to look in your router to check whether you might have been compromised or not.
If you have any questions or concerns, I’d encourage you to chat about the issue with other members.
