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

Tools / Dependencies

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
[dorkbot.indexers.wayback]
domain=example.com
[dorkbot.scanners.arachni]
arachni_dir=/opt/arachni
report_dir=/tmp/reports

Blocklist

The blocklist 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. The internal blocklist is maintained in the dorkbot database, but a separate file or databasecan be specified by passing the appropriate file path or connection uri to --external-blocklist. Targets are matched first against the internal blocklist and then optionally against any provided external blocklists.

Supported external blocklists:

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

Example blocklist 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 blocklists 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.

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 blocklist item. The result is a database where --list-unscanned returns only scannable urls. It honors the random flag to compute fingerprints in random order.

General Options

These options are applicable regardless of module chosen:

  --source [SOURCE]     Label associated with targets
  --count COUNT         number of urls to scan, or -1 to scan all urls
  --random              retrieve urls in random order
