bscan: an asynchronous target enumeration tool

bscan is a command-line utility to perform active information gathering and service enumeration. At its core, bscan asynchronously spawns processes of well-known scanning utilities, repurposing scan results into highlighted console output and a well-defined directory structure.

was written to be run on Kali Linux, but there is nothing inherently preventing it from running on any OS with the appropriate tools installed.

pip install bscan

Usage

bscan has a wide variety of configuration options which can be used to tune scans to your needs. Here’s a quick example:

$ bscan \
> --max-concurrency 3 \
> --patterns [Mm]icrosoft \
> --status-interval 10 \
> --verbose-status \
> scanme.nmap.org

What’s going on here?

• –max-concurrency 3 means that no more than 3 concurrent scan subprocesses will be run at a time
• –patterns [Mm]icrosoft defines a custom regex pattern with which to highlight matches in the generated scan output
• –status-interval 10 tells bscan to print runtime status updates every 10 seconds
• –verbose-status means that each of these status updates will print details of all currently-running scan subprocesses
  scanme.nmap.org is the host upon which we want to enumerate

bscan also relies on some additional configuration files. The default files can be found in the bscan/configuration directory and serve the following purposes:

• patterns.txt specifies the regex patterns to be highlighted in console output when matched with scan output
• required-programs.txt specifies the installed programs that bscan plans on using
• port-scans.toml defines the port-discovering scans to be run on the target(s), as well as the regular expressions used to parse port numbers and service names from scan output
• service-scans.toml defines the scans be run on the target(s) on a per-service basis

usage: bscan [OPTIONS] targets

an asynchronous service enumeration tool

positional arguments:
  targets               the targets and/or networks on which to perform enumeration

optional arguments:
  -h, --help            show this help message and exit
  --brute-pass-list F   filename of password list to use for brute-forcing
  --brute-user-list F   filename of user list to use for brute-forcing
  --cmd-print-width I   the maximum integer number of characters allowed when printing
                        the command used to spawn a running subprocess (defaults to 80)
  --config-dir D        the base directory from which to load the configuration files;
                        required configuration files missing from this directory will
                        instead be loaded from the default files shipped with this
                        program
  --hard                force overwrite of existing directories
  --max-concurrency I   maximum integer number of subprocesses permitted to be running
                        concurrently (defaults to 20)
  --no-program-check    disable checking the presence of required system programs
  --no-file-check       disable checking the presence of files such as configured
                        wordlists
  --no-service-scans    disable running scans on discovered services
  --output-dir D        the base directory in which to write output files
  --patterns [ [ ...]]  regex patterns to highlight in output text
  --ping-sweep          enable ping sweep filtering of hosts from a network range
                        before running more intensive scans
  --quick-only          whether to only run the quick scan (and not include the
                        thorough scan over all ports)
  --qs-method S         the method for performing the initial TCP port scan; must
                        correspond to a configured port scan
  --status-interval I   integer number of seconds to pause in between printing status
                        updates; a non-positive value disables updates (defaults to 30)
  --ts-method S         the method for performing the thorough TCP port scan; must
                        correspond to a configured port scan
  --udp                 whether to run UDP scans
  --udp-method S        the method for performing the UDP port scan; must correspond
                        to a configured port scan
  --verbose-status      whether to print verbose runtime status updates, based on
                        frequency specified by `--status-interval` flag
  --version             program version
  --web-word-list F     the wordlist to use for scans
