dorkbot

Scan Google (or other) search results for vulnerabilities.

dorkbot is a modular command-line tool for performing vulnerability scans against sets of webpages returned by Google search queries or other supported sources. It is broken up into two sets of modules:

  • Indexers - modules that return a list of targets
  • Scanners - modules that perform a vulnerability scan against each target

Targets are stored in a database as they are indexed. Once scanned, a standard JSON report is produced containing any vulnerabilities found. Indexing and scanning processes can be run separately or combined in a single command (up to one of each).

Quickstart

$ pip3 install dorkbot wapiti3
$ dorkbot -i google_api -o key=your_api_credential_here -o engine=your_engine_id_here -o query="filetype:php inurl:id"
$ dorkbot -s wapiti

  --flush-blacklist     Delete all blacklist items

Requirements

Tools

As needed, dorkbot will search for tools in the following order:

  • Directory specified via relevant module option
  • Located in tools directory (within current directory, by default), with the subdirectory named after the tool
  • Available in the user's PATH (e.g. installed system-wide)

Files

All SQLite3 databases, tools, and reports are saved in the dorkbot directory, which by default is the current directory. You can force a specific directory with the --directory flag. Default file paths within this directory are as follows:

  • SQLite3 database file: dorkbot.db
  • External tools directory: tools/
  • Scan report output directory: reports/

Configuration files are by default read from ~/.config/dorkbot/ (Linux / MacOS) or in the Application Data folder (Windows), honoring $XDG_CONFIG_HOME / %APPDATA%. Default file paths within this directory are as follows:

  • Dorkbot configuration file: dorkbot.ini

Config File

The configuration file (dorkbot.ini) can be used to prepopulate certain command-line flags.

Example dorkbot.ini:

[dorkbot]
database=/opt/dorkbot/dorkbot.db

Blacklist

The blacklist is a list of ip addresses, hostnames, or regular expressions of url patterns that should not be scanned. If a target url matches any item in this list it will be skipped and removed from the database. By default the blacklist is stored in the dorkbot database, but a separate database or file can be specified by passing the appropriate connection uri or file path to --blacklist. Note: --add-blacklist-item / --delete-blacklist-item are not implemented for file-based blacklists, and --flush-blacklist deletes the file.

Supported external blacklists:

  • postgresql://[server info]
  • phoenixdb://[server info]
  • sqlite3:///path/to/blacklist.db
  • /path/to/blacklist.txt

Example blacklist items:

regex:^[^\?]+$
regex:.*login.*
regex:^https?://[^.]*.example.com/.*
host:www.google.com
ip:127.0.0.1

The first item will remove any target that doesn't contain a question mark, in other words any url that doesn't contain any GET parameters to test. The second attempts to avoid login functions, and the third blacklists all target urls on example.com. The fourth excludes targets with a hostname of www.google.com and the fifth excludes targets whose host resolves to 127.0.0.1.

Scanner Modules

(general options)

These options are applicable regardless of module chosen

  • report_dir - directory to save vulnerability report (default: reports/)
  • label - friendly name field to include in vulnerability report
  • count - number of urls to scan, or -1 to scan all urls (default: -1)
  • random - scan urls in random order

arachni

Scan targets with Arachni command-line scanner.

Requirements: Arachni

Options:

  • arachni_dir - arachni base directory containing bin/arachni and bin/arachni_reporter (default: tools/arachni/)
  • args - space-delimited list of additional arguments, e.g. args="--http-user-agent Dorkbot/1.0 --timeout 00:15:00"

wapiti

Scan targets with Wapiti command-line scanner.

Requirements: Wapiti

Options:

  • wapiti_dir - wapiti base directory containing bin/wapiti (default: tools/wapiti/)
  • args - space-delimited list of additional arguments

Prune

The prune flag iterates through all targets, computes the fingerprints in memory, and marks subsequent matching targets as scanned. Additionally it deletes any target matching a blacklist item. The result is a database where --list-unscanned returns only scannable urls. It honors (a subset of) the options specified in SCANNER_OPTIONS as follows:

  • random - evaluate urls in random order when computing fingerprints
