I have been receiving a great many emails recently reporting issues within my website that, when gone back and looked up, have been reported as being Brute force attacks. Upon further inspection of their location. I have noticed a great deal of them are coming from the same IP address, and seem to be linked to Google, or Yahoo for example this site:
reports the following IP: 18.104.22.168, Which originates from google cloud, as brute force.
Is there a good way to distinguish between apparent brute force attacks, and Crawlers checking the site?
Update: all emails are being generated from production site. The error reporting is issuing a null reference exception.
