threats

After I have installed your plugin, I realized that posts are published without our permission. Is there possibility that myStickMenu plugin could be infected by threats?
Invasion websites posts so far are:
https://paper-help.us/
https://paper-helper.org/
https://essayswriting.org/
https://unitedessays.com
Is there a plugin scanner that I could use to exam them, please?
Tks.
