I have one website that is consistently getting weird form submissions. It's a contact form that captures name, email, subject, and message. Five to ten times per day it gets a submission where all the fields are filled in, the name and the email appear to be real, but unrelated (e.g., "Tom Jones", and "bob_smith@<major_email_provider>.com), and the subject and message are each one (apparently) random word (e.g., today, one had the subject "infrastructure" and the message "Ball").

Is this some known "attack" (I put that in quotations since at only 5-10 per day, it's clearly not a DOS or something)? Should I care about it? Should I do something about it?

  • Possible, but also possibly unlikely. How is the form protected? Do you have a Captcha on it? Does the processing script protect against direct submissions (i.e. post data from external sources that didn't come from a genuine form submission)? Mar 31, 2022 at 10:33
  • It does have Captcha (v3). I ... don't know about direct submissions. It's a Contact Form 7 form in WordPress, and I'm not sure how they handle that under the covers. Mar 31, 2022 at 13:13
  • OK, that's a fairly robust contact form plugin (it's perhaps the go-to contact form fr WP). Mar 31, 2022 at 16:12
