# C2 Frameworks

### Disowning binaries launched from SSH

* Often with C2 frameworks you will be in an SSH session on linux and will spawn a C2 payload to revieve your reverse connection back.
* When this process is launched in the context of you ssh session, it to will die if/when you exit the ssh shell.
* Need to disown the process before exiting your ssh session

```
#launch secondary payload
./bad.elf &
#view your current jobs 
jobs -l
#output
[1]-  4581 Running                 ./bad.elf &
#disown jobs
disown -h jobID
disown -h %2
## You should not see any jobs running on the screen ##
#verify with
jobs -l
##If disown is not on the target machine##
./bad.elf &!
```
