In this page, you can find a list of IPs that will occasionally try to log into your Synology via SSH. This blacklist has been carefully prepared by Marius Bogdan Lixandru over several years of investigations. Below, you will find instructions to implement the list and add it into your Synology NAS DSM or Synology router SRM device. This block list is completely compatible with all Synology NAS and Synology Routers like RT1900ac, RT2600ac, MR2200ac (follow the instructions below to add it on the router). The IP blacklist will be updated regularly. Remember, when you upload the file, upload it with the same name shown below: deny-ip-list this is the best and most effective Block IP List for your Synology NAS device. I will be reviewing the whole deny ip list every 1 month.
