    Hello,

    I noticed something interesting when I checked in on the firewall this morning. My firewall is still in learning mode but the list of whitelisted urls grew over the weekend.

    Taking a closer look I noticed a few things. (I have about 50 urls listed)

    1. All of the whitelisted urls list a single IP
    2. All whitelisted urls were created within a 2 minute window.
    3. The first two urls seem legit at first glance. Both are /wp-admin/admin-ajax.php but with different params. However, the same IP is listed as the rest of the urls. The same IP is listed for the rest of my whitelisted urls. All of which seem suspicious.
    4. The rest of my whitelisted urls are all paths to files, plugins, and themes that do not exist on my server. Judging by the filenames (almost all have to do with viewing or downloading) I can only come to the conclusion that someone (most likely a bot judging by the 2 minute window) was running through a list of known exploits.

    I’m wondering why my only whitelisted urls are from this one IP/user? The firewall has been learning for almost a week and the live traffic feed shows many visitors both bots and human. Why did it choose to whitelist traffic by this user? Especially since 95% of the urls are to non existing files, plugins, and themes. Why whitelist a 404?
