Smaller Fetch Payloads
This week, a significant enhancement was made to the already awesome fetch payload feature by our very own bwatters-r7. The improvement introduces a new option, PIPE_FETCH, which optimizes the process by serving both the payload and the command to be executed simultaneously.
This enhancement directly addresses the challenge of limited space by significantly reducing the size of the command that needs to be run. The PIPE_FETCH option works by initially generating a small command. When this compact command is executed, it fetches the actual, larger command that needs to be run. The fetched command is then directly piped into the shell, streamlining the execution process and making it feasible to use fetch payloads in scenarios where space constraints were previously a limitation.
