Many thanks for your submission. It looks good. We just need to fix up that predicate I think.

Thanks!

How can i do that ? could you help me ? with this ?

Absolutely! So if you attempt to validate your BCheck within Burp then you should see a syntax error from this line:

if {check2.response.status_code} is "200" and "\"type\":\"application\"" and "\"password\":" in {check2.response.body} then

The reason for this is the first and clause is incomplete and needs a 'subject'. So if you want to check the response body from check2, then you could write:

if {check2.response.status_code} is "200" and "\"type\":\"application\"" in {check2.response.body} and "\"password\":" in {check2.response.body} then

I'm not entirely sure of your BCheck detection logic though so you make need to modify this.

Hope that helps!
