Looks like someone (or something) is scanning your machine for vulnerabilities.

It’s a great time to make sure all your OS updates and applications are up to date :wink:

Doing some Google searches, there’s some info here on that:

Hi everybody,

Apache server records all incoming requests and all requests processed to a log file. The format of the access log is highly configurable. The location and content of the access log are controlled by the CustomLog directive.
