For most people – that is, those who keep their security up-to-date – these attempts to hack, using an old and easily available script – are harmless. It is an attempt to place a script into the core of a site so that it can be exploited. A conversation about the attempts is available here, with a few solutions. Banning the IPs being used works, but can be time-consuming as several people using a wide range of IPs appear to be trying this exploit.
The simplest solution, of course, is to have your security – and the version of WordPress you are using – up-to-date at all times. Other than that, the only thing that is likely to be effected is bandwidth.
