What are these Black marks on insulation?

So I am doing some renovations on my wet bar behind this wall (a project soon to be posted here) and in the process I needed to re-run some of the electrical. When I tore into the wall I found these weird black marks on the insulation everywhere the romex had been previously run. Now the existing romex shows no sign of heat damage or melting and I recently had the meter panel and breaker panel replaced last year. Anybody know what could have caused this and if I should be worried/concerned?

edit: and yes I know it is a big no no to have the leads exposed and connected like I do with wire nuts, but this is only temporary.
