Custom Binary

The command (cmd) plugin allows legba to interact with a custom executable and use either its exit code or a string pattern to determine a success or failure. It can be used to integrate with clients and utilities that are not natively supported by legba and parallelize their execution in order to attack credentials.

Options

Name	Description
--cmd-binary <CMD_BINARY>	Command binary [default: not set]
--cmd-args <CMD_ARGS>	Command arguments. {USERNAME}, {PASSWORD}, {TARGET} can be used as placeholders [default: not set]
--cmd-success-exit-code <CMD_SUCCESS_EXIT_CODE>	Process exit code to be considered as a positive match [default: 0]
--cmd-success-match <CMD_SUCCESS_MATCH>	String to look for in the process standard output to be considered as a positive match

Examples

Use the unzip utility to find the password of a password protected ZIP archive (as seen in this recipe):

legba cmd \
    --single-match \
    --cmd-binary unzip \
    --cmd-args "\\-oP '{PASSWORD}' \\-d /tmp {TARGET}" \
    -U "" \
    --password wordlist.txt \
    --target data/protected.zip
