Hi guys,


I am using Bigpipe, and there are some phishing windows poped up on my devices without touching/ clicking any link.


Does anyone find similar problem as well?




I have ever setup DNS server manually but unfortunately some site could not be resolve very well. so I changed back to Bigpipe default DNS.


Now some ads windows pop up even no phishing window so far.




I am afraid Bigpipe DNS got cache pollution or something but Bigpipe says there is no problem at all ,and  no one else find same problem.

As promised - without disclosing too many details there was a infected cheap Chinese DVR with a set, default root password, and several backdoor user accounts running on the OP's network. There is malware running on it and I suspect it has been doing some nasty things. I am not 100% sure what kind of malware it was running but looks to be linked to the Mirai botnet. It is bad, without authentication I could view the cameras.


This is why folks you NEVER port forward to any DVR's especially those purchased off ebay / aliexpress. You're just asking for trouble if you do. More expensive, name brand DVR's have their own secure cloud solution and others should only be accessed via a VPN.
