Plugin contains a link to malware infected site?

Hello, Wordfence has recently alerted me to the fact that this plugin contains a link to a url that Google has listed as a site containing malware. Specifically,
s (no space)

Is the plugin author affiliated with this site or has my plugin been compromised? Or is there another explanation? Thank you.
