- CNC-IPs-feed - Feed of IPs associated with command-and-control servers
- Phishing domains – Feed with domain addresses that are known to be associated to phishing attacks
- Malware domains - Feed with domain addresses that are known to be associated with malware
This document describes how to integrate the Bitdefender Advanced Threat Intelligence service with the ThreatConnect Platform. Once the integration is successful, the IOCs provided by Bitdefender Advanced Threat Intelligence service will be visible in the ThreatConnect platform and ready for usage.
Before proceeding with the installation, please ensure the following items are already available:
- Access to ThreatConnect instance
- At least one ThreatConnect API user (See Creating User Accounts)
- Bitdefender Authentication Token . This is provided by Bitdefender and it is used for authentication when connecting to Bitdefender Advanced Threat Intelligence services
Bitdefender Advanced Threat Intelligence app for ThreatConnect is available on Github at: Github Link. Download the app package (represented by the file with the tcx extension and install it in your instance.
The steps required to install the app are outlined in the ThreatConnect System Administration Guide (Install an App and Feed Deployer). Additionally, for more information you can contact your ThreatConnect Customer Success Engineer
Note: This step is not required for users who use Feed Deployer as it is automatically performed by the Feed Deployer Wizard
The ThreatConnect Platform provides the ability for customers to schedule applications as jobs, specifically known as Job apps, that can
be run at configured intervals. Bitdefender has developed a Job app for ThreatConnect customers by the name of Bitdefender Threat Intelligence that handles the complete process of downloading and ingesting the threat feed into the ThreatConnect Platform. In
order to configure the Bitdefender job, follow the steps mentioned below:
- In your ThreatConnect console, navigate to the gear-icon on the top menu bar. From the drop-down menu, click on Org Settings
- Select the Apps tab , then click on the small
+icon to add a new job - Enter a name for the Job name (e.g. Bitdefender Daily download). From the Run Program drop-down list select Bitdefender Threat Intelligence . Press Next to proceed to the next configuration screen
Note: If you cannot see Bitdefender Threat Intelligence listed as an option, double check the App Installation step above or contact your Customer Success Engineer
- In the next screen configure the Job parameters as follows:
- Bitdefeder API key : The auth token that was provided by your Bitdefender representative. If you do not have an API key, send an email to oem-sales@bitdefender.com
- Feed Type : choose the feeds for which you want data to be downloaded. The feed description can be found in the previous section - Introduction
- Hash type : for each file indicators, specify the hash type you want to be added. Currently for each file indicator, MD5, SHA1 and SHA256 are available as hash types. If there is a need to have multiple hashes available for each file indicator, recreate a new job and specify a different hash value
- Threat Rating : set the default Threat Rating assigned by ThreatConnect Platform to the imported indicators
- Confidence level : modify the Confidence score assigned to imported indicators
- Log level : specify the Job log level. Useful when debugging the job execution
- ThreatConnect Owner : select Bitdefender Threat Intelligence as the owner of imported data.
- Press Next to move to the next screen where options regarding job schedule can be configured:
Note: For Confidence level, we recommend leaving a value of 100 due to the low rate of false-positive it is expected to be returned by the Bitdefender Threat Intelligence feeds
Note: Bitdefender recommends configuring the job to run on a 1h interval to ensure that the latest data is fed in the ThreatConnect platform
- Finally, press Next to configure Notifications about job execution
- Press Save to store the job in the ThreatConnect platform
The new job created should be listed in the Jobs list table. The job will not run until it is marked as active.
To activate the job, move the slider in the right direction.
Note: Data will start flowing in the ThreatConnect Platform either when the scheduled time is met or when a manual trigger is performed. To trigger manually the job, go the Job previously defined and click the Run Job button located in the Options column
From time to time, Bitdefender retires indicators in its threat feed that it estimates are, no longer malicious and pose any significant threat.
These indicators previously ingested into the ThreatConnect Platform should also be deleted accordingly to avoid false-positives. ThreatConnect provides the ability for users to configure an indicator deprecation policy to allow ThreatConnect indicators to drop in confidence rating if their confidence rating is not being maintained and updated. Once the indicator rating reaches a minimum value (i.e.
0%), it can either be set to inactive or delete.
To configure an indicator deprecation policy depending upon the type of your ThreatConnect instance, please refer to the detailed knowledge-base article from ThreatConnect: CONFIGURING INDICATOR CONFIDENCE
DEPRECATION (See section Configuring Indicator Confidence Deprecation for an Organization and Configuring Indicator Confidence Deprecation for a Community or Source)
The recommended indicator deprecation rule settings for Bitdefender threat feed are as follows:
- Action at Minimum selected to be Delete so that indicators are deleted as soon as they reach minimum confidence
- Percentage checkbox checked which means that indicator confidence will be dropped as a percent of its previous
value - Confidence amount set to 100 so that 100% of an indicator's confidence is dropped
- Interval value set to 1 day which is the period after which the confidence emphasized textwill be dropped
- Recurring checkbox also selected so that deprecation is performed on a recurring basis
In simple words the recommended deprecation rule can be stated as, "After every day, drop the confidence of each indicator by 100% of its previous value and when any indicator's confidence reaches the minimum value, delete it from ThreatConnect"
To view the data, click on Browse button located in the top menu of ThreatConnect console. From here, there are two options: either filter by selecting a specific Indicator or by searching for a specific Indicator name .
The mapping between Bitdefender feed data and the Indicators and Tags that are added in ThreatConnect can be observed in the table
| Feed name | Indicator type | Tag |
|---|---|---|
| APT File IP | Address | apt-ip |
| APT File feed | File | apt-file |
| C&C IP | Address | c2-ip |
| Phishing Domains | Host | phishing-domains |
| Malware Domains | Host | malware-domains |
