3. Store your changes by selecting Save.

SSL certificates

To use an SSL certificate, it must be:

• Accessible on the EclecticIQ Intelligence Center host.

• Placed in a location that can be accessed by the eclecticiq user.

• Owned by eclecticiq:eclecticiq.

To make sure that EclecticIQ Intelligence Center can access the SSL certificate:

1. Upload the SSL certificate to a location on the EclecticIQ Intelligence Center host.

2. On the EclecticIQ Intelligence Center host, open the terminal.

3. Change ownership of the SSL certificate by running as root in the terminal:

   chown eclecticiq:eclecticiq /path/to/cert.pem
   

   Where /path/to/cert.pem is the location of the SSL certificate EclecticIQ Intelligence Center needs to access.

Data mapping

The sections below contain non-exhaustive information about how Group-IB Suspicious IP Socks Proxy data is mapped to EclecticIQ Platform entities and observables.

For more information about the Group-IB API schema, see the Group-IB API documentation.

Map to Indicators

Indicator field name	Mapped from GroupIB Socks Proxy JSON	Example value	Description
Title	items[].ipv4.ip	10.0.0.1	This is the title of the ingested Indicator.
Analysis	items[].source[]	Suspicious IP Socks Proxy Source: source.example.com	Contains information about the phishing kit.
Types	Always set to IP Watchlist	IP Watchlist	Type of Indicator.
Confidence	items[].evaluation.reliability	Medium	See Map reliability values to entity Confidence.
Tags	Suspicious IP - Socks Proxy items[].evaluation.admiraltyCode items[].evaluation.credibility	Various	See: Map Admiralty Code values Map credibility values to entity tags
Producer	Various	Various	See Producer/Information source.
Data marking	Various	Various	See Data marking.

Map Admiralty Code values

Group-IB uses the Admiralty System to assign reliability and credibility values to a piece of information in the admiraltyCode field. For example:

• Object A is assigned an admiraltyCode value of A1 means that it comes from an information source that is “Completely reliable”, and the piece of information can be “Confirmed by other sources”.

• Object B that is assigned an admiraltyCode value of D6 means that it comes from an information source that is “Not usually reliable”, and the piece of information is evaluated as “Truth cannot be judged”.

When these objects are ingested by EclecticIQ Platform, these values are added as tags to the entities to which the Admiralty System classification applies. For example:

• Object A with an admiraltyCode value of “A1” produces entities with these two tags attached:

  • Admiralty Code - Completely reliable

  • Admiralty Code - Confirmed by other sources

• Object A with an admiraltyCode value of “D6” produces entities with these two tags attached

  • Admiralty Code - Not usually reliable

  • Admiralty Code - Truth cannot be judged

The table below describes how admiraltyCode values are translated to tags on EclecticIQ Platform:

Group-IB admiraltyCode value	EclecticIQ Platform tags
A	Admiralty Code - Completely reliable
B	Admiralty Code - Usually reliable
C	Admiralty Code - Fairly reliable
D	Admiralty Code - Not usually reliable
E	Admiralty Code - Unreliable
F	Admiralty Code - Reliability cannot be judged
1	Admiralty Code - Confirmed by other sources
2	Admiralty Code - Probably True
3	Admiralty Code - Possibly True
4	Admiralty Code - Doubtful
5	Admiralty Code - Improbable
6	Admiralty Code - Truth cannot be judged

Map credibility values to entity tags

Group-IB assigns a credibility value to intelligence objects.

When Group-IB intelligence objects are ingested by EclecticIQ Platform, credibility values are added as tags to the resulting entities.

The table below shows how credibility values are translated into tags:

Group-IB credibility value	EclecticIQ Platform tags
0–33	Credibility - Low
34–66	Credibility - Medium
67–100	Credibility - High

Map reliability values to entity Confidence

Group-IB assigns a reliability value to intelligence objects.

When Group-IB intelligence objects are ingested by EclecticIQ Platform, reliability values are used to set the Confidence of an entity:

Group-IB reliability value	EclecticIQ Platform entity confidence
0–33	Low
34–66	Medium
67–100	High

Producer/Information source

Field name	Mapped from GroupIB Socks Proxy JSON	Example value	Description
Identity	N/A	Group-IB	Name of organization or person that created the information. Always set to “Group-IB”.
Roles	N/A	Initial Author	Role of information source. Always set to “Initial Author”.
References	items[].path items[].portalLink	https://bt.group-ib.com/?module=auth&back=https%3A%2F%2Fbt.group-ib.com%2F%3Fmodule%3Dbrand_phishing_kit%26action%3DgetFile%26path%01ba4719c80b6fe911b091a7c05124b64eeece964e09c058ef8f9805daca546b https://bt.group-ib.com/attacks/phishing_kit?searchValue=id:adc83b19e793491b1c6ea0fd8b46cd9f32e592fc	One or more links that lead to source information.

Data marking

Field name	Mapped from GroupIB Socks Proxy JSON	Description
TLP	items[].evaluation.tlp	This sets the entity TLP color using values in GroupIB Socks Proxy JSON.

Supported observables

The following table describes the observable types supported for this feed, and how they’re mapped from GroupIB Socks Proxy JSON:

ASN	Unknown	items[].ipv4.asn (Extracts only ASN number)	Indicator
City	Safe	items[].ipv4.city	Indicator
Country	Safe	items[].ipv4.countryName	Indicator
Country Code	Safe	items[].ipv4.countryCode	Indicator
Domain	Various	Mapped from Maliciousness items[].phishingDomain.Domain Mapped from items[].evaluation.severity. See Map severity to observable maliciousness and as entity tag. items[].phishingDomain.local Unknown	Indicator
IPv4	Unknown	items[].ipv4.ip	Indicator
Organisation	Unknown	items[].ipv4.provider	Indicator
Registrar	Unknown	items[].phishingDomain.registrar	Indicator

Map severity to observable maliciousness and as entity tag

Group-IB assigns a severity value to intelligence objects. When that intelligence object is ingested, its severity value is inherited by the entities and observables it produces.

severity in observables

When Group-IB intelligence objects are ingested to produce observables on the EcleciticIQ Platform, its severity value is used to set the Maliciousness of the observable.

The table below describes how severity values are translated to observable maliciousness:

Group-IB severity value	EclecticIQ Platform observable maliciousness value
red	Malicious (High confidence)
orange	Malicious (Medium confidence)
green	Malicious (Low confidence)

severity added to entities as tags

When Group-IB intelligence objects are ingested to produce entities on EclecticIQ Platform, its severity value is translated to a corresponding value and added as a tag to entities produced from it:

Group-IB severity value	EclecticIQ Platform tags
red	Severity - red
orange	Severity - orange
green	Severity - green
