Update Forms J4 (attacked)

Hi,
I’ve been hit by numerous attacks across dozens of websites where I had the form installed. We even suspect that email accounts may have been compromised on sites where SMTP was configured. Now, I have to go through each site and rebuild them from a clean installation, a massive undertaking.
I would have appreciated more direct communication regarding the severity of the situation.
All my sites are running on J5 or J6, but I have one site on J4.4.14 where I can't update the component. Which file should I use to at least resolve the issue?
Thanks.
Thanks.
