I was wondering something about Recaptcha validation.
I currently implemented the recaptcha in my form, but the recaptcha doesnt seem to prevent the submit handler of the form. So I assume I have to write my own specific code for it. However!...is this bot-safe? Cant bots just disable the recaptcha validation and still submit the form?
Please enlighten me,
Thanks!
You need to plug the recaptcha in a manner that it is required to have a successful test to submit the form. As you can see, on the official docs of Google, they will handle the challenge for the user (or bot) and send you a success, either false or true.
If it does not pass, do not allow them to submit the form. If they do disable the JS, they will not be able to submit it neither ofc.
And yeah, a recaptcha works well against bots, it's the goal of it. Some low recaptchas can be a bit too naive and data bots could detect some patterns and still succeed a submission but they are a few and you can still go for a score of 1 or 0.9. It basically determines "how much are you human", 1 guarantees that it's really unlikely that it's a bot.
Why isn't the submission blocked in your case ? It's the thing that you need to investigate or post a question with it's content.
This module is aimed towards Nuxt, so it may help be a good start.

I recently picked up NuxtJS en Vue to write a blog and wish to add a Google Recaptcha.
The best validation is a server side validation obviously. So before users can submit the form, the back-end needs to verify the google recaptcha response. I was wondering if I could do this through my Nuxt-app itself?
So instead of having a method that validates if there is a recaptcha response, I was wondering if I can write something in a special hook(maybe validate()?) that is unavailable from bots on the clientside but still checks if the recaptcha response is valid. Before sending the form.
Is this possible, is yes/no how and why not? Please enlighten me!
Cheers and thanks in advance.
Technically it might be possible to validate the Recapthca key on the frontend, but since you need to use your private key to do so, your private key would be exposed.
Also it shouldn't be the frontend's decision whether or not to submit the form based on a Recaptcha. The frontend should submit the form - and the backend should decide how to handle the submission based on the Recaptcha result. Otherwise bots would still be able to hit the endpoint.
My client needs me to implement captcha on his form. The form's action is set to an external page, to which we do not have access.
I wanted to use Google's reCaptcha but it seems that piece of code (which does the checking) needs to be placed in the targed page (which we cannot access).
What is the solution? I tried with using some simple Javascript array and jQuery checking of the value but it seems that spammers after couple of months learned how to dig the values out of the page code (yes, the values are written there, it's javascript - and I do not know better way) because the spam is arriving again.
A good client-side way would be even better. If you know a script or some code to be used here it'd be very appreciated.
Host another server with captcha and submit your form there. In case of success, submit the form from the captcha server to the one you don't have access to.
I am tracking Form Submission leads through Event triggering on my Google Analytics account. The Form in website is built in such a technical way that Form submission is happening through "Submit" tag, instead of normal "Click" way. The source code image of my form's submit button, may help you in getting this. Please use below link to open the image, as StackOverflow is not allowing me to post the images:
https://www.dropbox.com/s/q4ltjs46knjwcrc/Event%20Tracking%20Code%20Example.png
Due to the nature of form, I have placed the "OnSubmit" Event tracking code in the Form ID tag of the source code. Again, please use the below link to open the same:
https://www.dropbox.com/s/443fzcz6a6jrfsu/Form%20Submit%20Tag.png
Now, my query is, have I installed the event tracking code properly? I mean, would this event be triggered, when someone submit form on my website successfully?
This is running since a couple of days and I have been reporting the leads as well in my GA account through this event, but not getting the leads in the inbox. When checked with my technical team, they said there might be server issues, due to which the lead information is not coming to inbox.
I am not sure, whether it is a server error causing leads information going somewhere else other than inbox, OR it is an wrong event tracking that is showing me wrong numbers??
Can anyone please help me on this. Thank you very much.
The question about the tracking code being installed properly could be possible, it justs depends on your kind of implementation. However, do note that Google recommends to add a slight delay between the moment the action takes place (in your case, the form being submitted) to the moment that Google can receive the event in order to be logged.
Consider about adding a small delay before your form gets sent. Take a look at this recommendation from the Analytics Help.
I have website which is luckily on top of Google but there are spam messages with backlinks of different websites from spammers too so what i thought a solution to prevent visitors from putting back links in Multiline Text Area ?
I have tried with required field validation and some other ways but unlucky yet.
I am bit familiar with Javascript but after searching i did not find any javascript to prevent backlinks in text area.
If any one can help me a bit or just give me an idea ?
Client-side validation is easy to bypass, but server-side validation should not.
I mean that client-side validation may work with human users but spam bots may send requests to your server bypassing your form or they even don't understand JavaScript.
Do the whole client-side validation for human users but repeat the same validation in the server-side so no one will be able to bypass your rules.
I am a web developer for a web site that is occassionally plagued by form bots. Recently I received an error notification of a problem with the form submission that should be impossible for a human user. You cannot submit the form without JavaScript enabled but the server side script received a form field value that the JavaScript validation will not allow.
I suspect that a form bot managed to submit the form without running the JavaScript but I'm not entirely sure this is the problem because a real user had a similar problem. I know how to use honeypot fields as a countermeasure for form bots but I need to test my countermeasures. Therefore I need a working form bot to attack my form so I can see what the result would be and to verfiy that my countermeasures will work.
I think you can use PHP with Curl to submit web forms but I can't find any sample code. I would prefer to use an actual form bot so I can be sure that the honeypot fields aren't easily circumvented.
Does anyone know what is currently being used to attack web forms? How do you test your countermeasures to ensure they are effective?
Personally, I use a FireFox extension called Tamper Data. You submit the form normally, but then you can modify the HTTP parameters (Variables, cookies, etc) before it's sent to the server. That way, you can manually change the validated fields. You could automate it with PHP and CURL...
The thing is, you don't want to run an actual bot against it, because that would only test one (maybe two) methods of breaking your validation. You want to run your own, that way you can test every possible combination that you can think of. If you automate it with PHP/CURL, you could then run the test with every change (an integration test) to verify that you didn't "break" anything... It shouldn't be too hard to write, since the CURL functions are pretty well documented...
What about captchas to protect your form?
