Article Summary

Overview

The ThreatConnect® Domain-Spinning Workbench Spaces App provides four algorithms for identifying potential domain squats related to an input domain name. The list of domain names it provides can be used to take preventative measures against potential squats or actual squats. You can import selected domain names and registrant email addresses into ThreatConnect as Indicators. The methods for identifying squats include open-source algorithms and algorithms developed by the ThreatConnect Analytics team.

Important
Domain-spinning algorithms may produce Indicators unauthorized by a System-wide Indicator import rule, resulting in a failure during the application’s import process. To identify the offending Indicator, review the operating system (OS) logs associated with the Import Playbook.

App Features and Recommendations

Domain Squat Identification Algorithms

The Domain-Spinning Workbench App provides four algorithms for identifying domain squats:

  • Bitsquatting: The Bitsquatting algorithm finds domains that would receive traffic if a bit flip occurs in an Internet device when a given domain is requested.
  • DNSTwist: The DNSTwist algorithm finds domain names that look similar to a given domain name or are possible variants of a given domain name if a user makes a typo when entering in the domain name (“typosquatting”).
  • URLCrazy: The URLCrazy algorithm detects many different variations of a domain, including basic bitsquatting, typosquatting, and common misspellings.
  • XNTwist: The XNTwist algorithm detects internationalized domain names that may be squatting on a domain name.

WHOIS Lookup Options

The Domain-Spinning Workbench App provides two options for retrieving WHOIS data:

  • DomainTools WHOIS Lookup: This option is the best choice for users who have a subscription to the DomainTools service.
  • ThreatConnect WHOIS Lookup: This option is the best choice for users who do not have a subscription to the DomainTools service.

Preparatory Recommendations

It is recommended that all of the Playbook URLs be saved by an Organization Administrator as text variables in your Organization for easier entry into the App configuration and subsequent modification. For instructions on creating variables, see the “Variables” section of ThreatConnect Organization Administration Guide.

It is recommended that you set your Log Out Interval to at least 2 hours so that your logins do not time out during the spin. For instructions on changing your Log Out Interval, see the “Overview Tab” section of My Profile.

Adding and Configuring the App

  1. Follow the steps in the “Adding a Central Space and Configuring an App” section of Central Spaces to create a Space and add the TCS - Domain Spinning v1.0 App to the Space. The final screen in this process will look like Figure 1.

    Figure 1_Domain-Spinning Workbench_7.1.0

     

  2. Click ConfigurePencil icon_Domain-Spinning Workbenchto configure the App. The Configure App screen will be displayed (Figure 2).

     

    • Owner: Enter the name of the Organization that will own any Indicators and other objects imported from the Domain-Spinning Workbench App, or use the $ button to select an owner from the list of variables that is displayed.
    • Tag to Apply to Objects Created During Import: Enter a Tag to apply to all objects imported from the App. A default Tag is provided, and it may be modified if desired.
    • Types of DNS Records to Look Up: This field lists default DNS Lookup record types that the App will access. Add or remove any record types as desired.
    • Maximum Time of Results to Cache (in Days): The information generated by the App is stored in ThreatConnect’s DataStore. This field indicates the maximum amount of time the data are cached in the DataStore before they are refreshed upon another run of the App. The default amount of time is 14 days.
    • Domain Spinning Playbook URL: Enter the URL for the Domain Spinning Playbook, or, if it has been entered as a variable (see the "Preparatory Recommendations" section), use the $ button to select it from the list of variables that is displayed. The following Playbooks are valid choices: Bitsquatting, DNSTwist, URLCrazy, and XNTwist. Each Playbook uses a different algorithm to identify domains.
    • DNS Lookup Playbook URL: Enter the URL for the DNS Lookup Playbook, or, if it has been entered as a variable (see the "Preparatory Recommendations" section), use the $ button to select it from the list of variables that is displayed.
    • WHOIS Lookup Playbook URL: Enter the URL for the Whois Lookup Playbook, or, if it has been entered as a variable (see the "Preparatory Recommendations" section), use the $ button to select it from the list of variables that is displayed. The following Playbooks are valid choices: DomainTools WHOIS Lookup (requires a key; available only to users who have purchased a subscription to DomainTools) and ThreatConnect WHOIS Lookup (available to all ThreatConnect users; note that this service does not produce emails).
    • Import Playbook URL: Enter the URL for the Import Playbook (Domain Squat Import), or, if it has been entered as a variable (see the "Preparatory Recommendations" section), use the $ button to select it from the list of variables that is displayed.
    • Click the SAVE button.
      Note
      Instead of changing configuration settings in one instance of the Spaces App in order to toggle between Domain Spinning Playbooks or types of Whois Lookup Playbooks, you can add multiple instances of the App can be added to the Spaces screen, each with its own configuration settings (e.g., one that uses the Bitsquatting Playbook and DomainTools Whois Lookup, another that uses the DNSTwist Playbook and ThreatConnect Whois Lookup, etc.), so that a different instance of the Spaces App can be used instead of changing configuration settings in one instance.
  3. The Spin screen for the App will be displayed (Figure 3).

     

Using the App

  1. On the Spin screen (Figure 3), enter a domain name and then click the Spin button. This example uses “google.com”.
    Note
    Clicking on the down arrow to the left of the Spin button will display a list of previously searched domains, if any.
    Note
    The Spin button will be grayed out and unclickable until a period and the first letter of a top-level domain (e.g., .com, .edu) are added to the entry. To get results that make sense, enter the entire top-level domain (e.g., “google.com” rather than just “google.c”) before clicking the Spin button.
  2. The domain-spinning process will begin. If the domain has been spun within the Maximum Time of Results to Cache (Figure 2), then the spinning process will be short (i.e., a few seconds to several minutes), as the App will be searching only for new results since the last cache. If the domain has not been spun within the Maximum Time of Results to Cache, the process will probably take a long time (i.e., 15 minutes to 2 hours or more). Once the spin is initiated, the screen will indicate that it is collecting data for spun domains (Figure 4).
    Note
    If at any point, the spin gets interrupted (e.g., your login times out, you close out of ThreatConnect), a subsequent re-spin will take less time, because the results of the interrupted first spin will have been cached.

     

  3. After the spin is underway, the screen will change to a countdown indicating the number of domains in the spin that have not yet had their data collected (Figure 5).
    Note
    The countdown does not always move in real time. It is best used as a general measure of progress rather than an exact indicator of how many domains remain in the spinning process.

     

  4. When the spinning process finishes, a screen with the results will be displayed (Figure 6).

    Graphical user interface, application  Description automatically generated

     

    • The box on the left side of the screen in Figure 6 provides Whois Data and DNS Data for the spun domain. Both sections may be collapsed by clicking on the minus sign to the left of their respective section header. The text to the right of each section’s header shows when the data in that section was last cached. To refresh the data, click RefreshRefresh icon_Domain-Spinning Workbenchto the right of the cache information.
    • The Domain Squats box on the right side of the screen in Figure 6 provides all potential domain squats identified by the Domain-Spinning Workbench App. The number of squats found is shown in parentheses next to the Domain Squats label. A detailed explanation of these results is provided in the “Viewing Domain Squats Results” section.
    • Click the Back button above the Domain Squats box to return to the main spin page (Figure 3).

Viewing Domain Squats Results

The results of the Domain-Spinning Workbench, as shown in Figure 6, are provided on the right-hand side of the screen. Each result consists of several components, as shown in Figure 7.

Graphical user interface, text, application, email  Description automatically generated

 

  • Squat domain name: The domain name of the potential squat. The name is displayed twice, once in a box and once in light-gray text. If the domain has Unicode characters in it, the light-gray text will display the Unicode characters, while the text in the box will display an IDNA-encoded (punycode) domain name.
  • Registrant email address: The email address under which the domain name is registered with Whois.
  • Whois Data: Whois information for the potential squat. Click the plus sign (Figure 6) to expand this section. The “cached at” text on the right-hand side of this element shows when the data in this section was last cached. To refresh the data, click RefreshIcon  Description automatically generatedto the right of the cache information.
  • DNS Data: DNS information for the potential squat. Click the plus sign (Figure 6) to expand this section. The “cached at” text on the right-hand side of this element shows when the data in this section was last cached. To refresh the data, click RefreshIcon  Description automatically generatedto the right of the cache information.
  • Label: The dropdown box at the upper-right corner provides three options (Suspicious, Potential, and Malicious) for classifying the danger level of the squat. Domains that have a registrant email address (i.e., the domain name is registered) have Suspicious as their default label. Domains that do not have a registrant email address (i.e., the domain name is not registered; “Domain Not Registered” is displayed in place of the registrant email address) have Potential as their default label. Users can change the label for each item to reflect their assessment of the danger level of the squat. Thus, changing a squat’s label to Malicious indicates that you have determined that the domain is malicious.
    Note
    The label applies to both the squat domain name and the registrant email address.
  • DeleteTrash icon_Domain-Spinning Workbenchicon: Deletes the domain from the results set. Note that clicking DeleteIcon  Description automatically generatedwill immediately delete the domain. No confirmation window will be displayed.

Importing Domain Squat Results into ThreatConnect

Follow these steps to import and save squat domain names and registrant email addresses as Indicators in ThreatConnect:

  1. Select the checkbox for each item that you want to import, or click the Select All button at the top of the Domain Squats box to select everything. To clear all selected items, click the Select button.
    Note
    Clicking the Select All button will select all items in the search, not just the ones on the current page.
    Important
    If a squat domain name is selected, but the registrant email address associated with it is not, the registrant email address will not be imported. However, if a registrant email address is selected, but the squat domain name associated with it is not selected, the squat domain name will still be imported.
  2. To view all selected items, click the Show Selected button. The Domain Squat Results pane will display only items that were selected (Figure 8). Click the Show All button to go back to displaying all squat results.

  4. Click the Import button on the Do you want to create these entities? window to create the Incident and import the Indicators.

When the import process is complete, the Details screen for the new Incident will be displayed. The Indicators will all be associated with the Incident, and the Incident will be tagged with the text entered in the Tag to apply to objects created during import field in Figure 2 (Domain Spinning Workbench in this example). The squat domain names will be imported as Hosts, and the registrant email addresses will be imported as Email Addresses. Figure 10 shows the Associations tab of the Incident’s Details screen, demonstrating that the six selected Indicators have been associated to the Incident.

Figure 11 shows the Details screen for one of the imported Indicators. It is associated to the Incident created by the Domain-Spinning Workbench App and the other five Indicators imported into ThreatConnect, as indicated by the to the right of the Associations tab name. Also, in addition to the Tag specified in the Tag to apply to objects created during import field in Figure 2 (Domain Spinning Workbench in this example), a Tag for the Suspicious label was created and applied to the Indicator (Domain Spinning: Suspicious in this example).

Important
Every new import from the Domain-Spinning Workbench App creates a new Incident, where each Incident is imported under the name Domain Squats for <domainname.com> (e.g., Domain Squats for google.com). If an Incident with the same name already exists (e.g., if an import for Domain-Spinning Workbench results for a particular domain has already occurred), then a new Incident will be created with the same name. The Incidents will not be associated with each other. If you want to associate the Incidents, you must do so manually. If an imported Indicator already exists in ThreatConnect, the existing Indicator will be updated with the information brought in from the Domain-Spinning Workbench App (i.e., a new Indicator will not be created.=).
Note
The Whois and DNS data found by the Domain-Spinning Workbench App will not be imported into ThreatConnect. Those data must be viewed from inside the App by expanding the respective sections for a particular squat domain name, as shown in Figure 7. However, you may also view Whois registration information for Host Indicators and DNS resolutions for Address and Host Indicators on the Details screen.
