Custom HTTP Header not applied

[0xArt3mis]

Hi,

I wanted to change the HTTP request headers of the implant to send a custom header. I therefore exported the default c2profile (c2profile export -f default.conf), tried to integrate the following in the headers array in implant_config:

"headers":[{"name":"custom_header_name","value":"custom_header_value","probability":100,"Methods":null}]

and then imported the file using the -o switch to override the config.

c2profiles import -f default.conf -o

and restarted the listener.

Somehow the header is not sent during the checkin request of a new implant. also when I view the c2profile using the command: c2profiles, the header is not shown in client headers.

What is the correct way to add a custom HTTP header to each request of generated implants?
