It has come to our attention that a rogue botnet is currently using a
vulnerability in the RouterOS Winbox service, that was patched in RouterOS
v6.42.1 in April 23, 2018.

Since all RouterOS devices offer free upgrades with just two clicks, we
urge you to upgrade your devices with the "Check for updates" button, if
you haven't done so already.

Steps to be taken:

- Upgrade RouterOS to the latest release
- Change your password after upgrading
- Restore your configuration and inspect it for unknown settings
- Implement a good firewall according to the article here:


All versions from 6.29 (release date: 2015/28/05) to 6.42 (release date
2018/04/20) are vulnerable. Is your device affected? If you have open
Winbox access to untrusted networks and are running one of the affected
versions: yes, you could be affected. Follow advice above. If Winbox is not
available to internet, you might be safe, but upgrade still recommended.
