Hello,
Thank you for contacting support.
Why do you suspect that the root cause was our plugin? Do you have any logs on the server that could confirm this?
In any case, a complete security audit should be done on the website as that code is not standard on the file you mentioned so it’s likely you have malware on the website.
Don’t hesitate to get in touch if you have any other questions.
