Increase In Brute Force Attacks on American Networks By Chinese Networks on 4th of July.

I started to track my security logs a lot more since I began to notice the amount of alerts I was getting via email on holidays. There is definitely a connection, American networks are under attack during American holidays specifically from 00:00 to 14:00, this time the attacks weren’t just coming from Chinese networks but Mexico & France.

Here is a list of the latest culprits…
