Hello Everyone My nodered server has been hacked, by adding some invisible nodes to my flows.json while I was working on it. I detected it because of a nodered message stating that some nodes where changed without ay action from me. Looked like someone edited another instance of the flows.json fil…

[image] jbudd: count by a notification on the editor once successfully logged in Nice idea but what is the call to action if I see this message? Is there a log with IPs and even then, it's the past so I can't know whether those IPs will come again. A message like this is more confusing than …

[image] gregorius: A message like this is more confusing than useful - IMHO - since there is nothing I can do except click it away. You could also investigate as to what was connecting to your device. The message itself is a call to do something, whether you or others do is entirely in your …

[image] dceejay: Obviously there could be more - as per blocklists allowlists etc - but ideas on making those easy to setup much appreciated. What about a restriction on the local network (192.168.1.1/24) - the script can get the IP address and ask the user if it is correct? I fear that the …

I was just thinking - at the moment - of counting bad password submissions, not really connected to blocking outside attackers. It could be my bad keyboard skills, someone else in the office trying to share my work or aliens from the internet. Not actually sure how NR could maintain a count (over …

I know, but doing it during the NR installation would be more beneficial because very few people will do it before having pain.

[image] E1cid: The message itself is a call to do something, What? There is a message and I don't know what to do ... but I have to do something. If I was a newbie and saw that message, what would I do? Probably come here and ask ... That shouldn't be the point of the message.

If you don't know, then you ask, or play stupid your choice.

[image] jbudd: Not actually sure how NR could maintain a count (over reboot/restarts), never mind a list of IPs. Create a flow, use the flow context to store the IPs and block as seen fit. Using a http-in node as the entry point and bob's your uncle! My blog is one http-in node and many litt…
