It seems as they are on a blacklist of your duck dns but not because they tried to hack you but because on those IPs where malware / phishing websites hosted. Likely somebody used those server now as Proxy / tor exit node. It’s of course possible he had bad intentions but that’s not the reason he was blocked. (at least the screenshot suggests that)

Concerning the attack on the wifi I’m not sure what you mean. Do you mean the wifi router / internet modem? Because to gain access to your wifi network from different countries seems very unlikely.
