Get Detailed Explanations for How Infrastructure is Attributed to an Organization's Assets

Attribution Explainability provides detailed explanations for how infrastructure is attributed to an organization’s assets. The data fields give insights into domains and IP/CIDR.

Domain Source

The domain attribution process identifies why and how a domain is linked to the organization. It uses the Source and Attribution Reasons fields to provide transparency.

Important Notes

• Historical domain data (prior to [release date]) may lack attribution reasons, so “No Source” is displayed in the Source field.
• Detailed attribution data is available on the Attribution tab of the Infrastructure page, but older records might not always be available in the Change Log.

Source

The Source field indicates the method used to associate the domain with the organization. It can have the following information:

Customer-Provided

Added upon request by the organization.

DNS Domain

Identified using DNS records.

GIA Domain

Attributed through the Bitsight Graph of Internet Assets (GIA) using machine learning and data correlation.

Primary Domain

The main domain representing the organization online.

Registered Domain

Derived from WHOIS registration information.

Redirect

Domains that automatically forward visitors to the organization's primary domain through redirects.

Attribution Reasons

The Attribution Reasons field explains why an asset (such as domain) is linked to and attributed to an organization. This can include:

• Evidence from domain registrations (e.g., WHOIS data).
• Correlations with other infrastructure attributed to the organization.
• Manual research or customer-provided data.

Customer-Provided

Company-provided assets.

Slug Name: CUSTOMER-PROVIDED

DNS

The domain, attributed due to its DNS records.

Slug Name: dns_domain

GIA Domain

The domain attributed to the organization using the Graph of Internet Assets (GIA).

Slug Name: graph_domain

Primary Domain

The primary domain this organization uses as its internet presence.

Slug Name: primary_domain

Registered Domain

The registered domain, attributed based on WHOIS registration information.

Slug Name: registered_domain

Secondary Domain

A secondary domain attributed through manual research. It is used as a foundational point for attributing additional infrastructure, including other domains and IP addresses, from various data sources.

Slug Name: secondary_domain

Manual Domain

The domain attributed through manual research.

Slug Name:: manual_domain

Common Reason Codes

Reasons for attribution.

Customer Confirmation

Assets explicitly provided by the customer (company-provided assets).

DNS Mapping

Shows associations such as IPs to domains or domains to IPs (e.g., 104.22.74.242/32 mapped to example.com).

Manual Assignment

Attributions based on manual research.

Observed Associations

Identifies shared usage of infrastructure or other overlaps, such as domains and IPs seen in DNS traffic.

Redirects To/From

Indicates redirections between domains or URLs, such as example.com redirecting to www.example.com.

Unique Identifiers

Links based on artifacts such as email addresses, phone numbers, logos, or physical addresses.

Examples

Domain Attribution

• Redirects: example.com redirects to www.example.com.
• DNS Mapping: 104.22.74.242/32 maps to example.com.

IP Attribution

• IPv4 Mapping: 192.168.1.1 attributed to a company via DNS records.
• IPv6 Mapping: 2001:db8::ff00:42:8329 linked through observed associations.

Other Identifiers

• Email Address: Associated with the organization through WHOIS records.
• Logo: Identified in metadata or website records.
• Phone Number: Attributed via public or private records.

Evidence for Domains

The Evidence field describes why a particular asset is suggested.

Summary Explanation

The Evidence field contains a series of summarized relationships between assets. Each summary indicates a potential connection, such as redirects, DNS mappings, certificates, or web page associations.

Examples:

• professional.bu.edu to cpe.bu.edu suggests a redirect observed between two assets.
• xmail.bu.edu to newmail.bu.edu indicates DNS mappings leading to an asset association.

Step-by-Step Relationship Breakdown

Each step provides crucial context that explains how the connection was inferred, allowing users to validate the suggested assets.

The context includes:

From

The starting asset or domain in the relationship.

Last Seen

The most recent date this relationship was observed, ensuring users can evaluate its relevance.

Record

The observed data source for the relationship.

Relation

The type of connection or linkage between a company and assets during attribution. Relations:

• associated with
• has
• has nameserver
• is nameserver for
• is redirected from
• is routed from
• linked to
• managed by
• manages
• maps to
• redirects to
• registered with
• relates to
• routes to
• used to register
• verified by
• verifies

To

The resulting asset or domain in the relationship.

Example Breakdown

Summary: cpe.bu.edu to professional.bu.edu

Steps:

• From: cpe.bu.edu
• Relation: is redirected from
• To: professional.bu.edu
• Record: REDIRECT
• Last Seen: 2024-09-13

This means that professional.bu.edu was observed redirecting traffic to cpe.bu.edu as of September 13, 2024 based on a recorded redirect.

How to Interpret and Use the Evidence

1. Evaluate Summaries: Use the summaries to get a quick overview of how the asset is linked to the organization.
2. Validate Steps: Dive into the step-by-step relationships to verify the data against internal records.
3. Check Relevance: Pay attention to the Last Seen date to ensure the data is current.
4. Assess Data Sources: Consider the Record Type (e.g., DNS or certificate) to understand the strength of the evidence.
