Unusual Log File Being Generated

I noticed I started getting E-Mails from iThemes Security about a File Change in error_log.

On further investigation this is generating this on a frequent basis:
[25-Nov-2018 21:03:44 UTC] PHP Warning: file_put_contents(/var/www/clients/client74/web304/web/wp-content/uploads/ithemes-security/logs/event-log-adam-zook-consulting-pPrxqCmj6GUP8p1C6NsegS1bjrlpGx.log): failed to open stream: No such file or directory in /home/actualdomainid/public_html/wp-content/plugins/better-wp-security/core/lib/log.php on line 176

I replaced my company name with actualdomainid in this error. /var/www/clients/client74/web304/ was the location my site was on with my previous hosting provider though and I do not have a clue who adam-zook-consulting is and doing a google search has yielded no results either.

Sure enough checking /public_html/wp-content/uploads/ithemes-security/logs there is a file over 10MB called event-log-adam-zook-consulting-pPrxqCmj6GUP8p1C6NsegS1bjrlpGx.log.1 and a newer one that is 6MB called event-log-adam-zook-consulting-pPrxqCmj6GUP8p1C6NsegS1bjrlpGx.log

There is a lot in that file and my domain name is mentioned a lot. I have removed my domain name below:

It looks like the IP 5.153.225.102 is the old hosting provider.

If anyone can offer any advice it would be appreciated.
