Collective Intelligence Framework v3 - Part 1

By Kunal Patil, Senior Threat Hunter

Basic About CTI


Cyber Threat intelligence(CTI) is a Technology which helps an Organization to collect and Analyze threat data received from multiple resources. Cyber threat intelligence is an automation process where it accumulate data from various external resources (such as FEEDS) and recognize the threats suitable for the Organization. By importing the Data from CTI, the next step is to exporting the CTI data into Existing Security systems.

 Collective intelligence Framework is an underlying Structure of CTI which helps any organization to gather all Threat Data at one place.

In this blog we are discussing how to Install Collective Intelligence Framework v3 (Bearded Avenger) into security structure.

Details Information About CIF you will found at : csirtgadgets

Basic Requirements for Bearded Avenger CIF v3 :

  • OS: Ubuntu 16 LTS,  x64
  • RAM: 16GB
  • Cores: 4 (As Sqlite, ElasticSearch, CIF-Router among other apps would be running on same instance)
  • HDD Capacity: 100GB
  • Internet Access for feeds collection
  • Root Privileges (required to setup the framework)
  • VM Snapshot: A snapshot to be taken after vanilla installation of OS.

STEPS :


Firstly, we need to install Dependencies required for implementing CIFv3, Dependencies like SQLite and Elasticsearch need to Install in Beginning.

1) Install SQLite


Here we are installing SQLite 3.17.0 on Ubuntu 16.04 using below commands :

  • sudo add-apt-repository ppa:jonathonf/backports  


  •  sudo apt-get update && sudo apt-get install sqlite3


 
To remove SQLite:

  • sudo apt-get remove sqlite3

To check whether SQLite installed successfully

  • apt list --installed | grep sqlite


    

2) Install Elastic Search


To Install Elastic Search we first we have to get JDK 8 , if JDK is not installed hit the below Commands to install JDK :

  • sudo apt-get install default-jdk
  • javac -version
  • sudo apt-get update



After successfully installation of JDK 8, proceeds with the Elastic Search installation, Here we are installing Elasticsearch v5.6.3.

Commands to Execute : 

a) wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.6.3.deb sha1sum elasticsearch-5.6.3.deb



    
b) sudo dpkg -i elasticsearch-5.6.3.deb




c) Start the Elasticsearch services using below commands:

  • sudo systemctl enable elasticsearch.service
  • sudo systemctl start elasticsearch.service
  • sudo systemctl status elasticsearch.service



d) Final output should be like below image to confirmed elasticsearch installation is successfully
done : GET 127.0.0.1:9200



3) Install Collective intelligence framework

 First we required to install dependencies to install CIFv3, i.e Bearded Avenger Deployment kit

Deployment kit is available at GIT HUB , it will install dependencies like MarkupSafe, jinja2, PyYAML, six, pycparser, cffi, pynacl, enum34, idna, asn1crypto, ipaddress, cryptography, bcrypt, pyasn1, paramiko and ansible. Now hit below commands :

  • tar -zxvf bearded-avenger-deploymentkit-3.0.x.tar.gz
  • cd bearded-avenger-deploymentkit-3.0.x
  • sudo bash easybutton.sh


Now Install Bearded Avenger CIFv3 by getting code from GIT HUB sdk-master, Enter the below commands :

  • sudo python setup.py install

After this Command OUTPUT be like Below image :


Now by default it Creates cif user at /home, switch the USER to cif and hit command cif :

 Finally the CIFv3 Bearded Avenger has been Executed Completely, final OUTPUT be like this:




How Start with CIF and Filter FEEDS from different resources will Be Coming in my NEXT BLOG, CIFv3 Part 2

Real Time Response Real Time Response is a powerful tool that gives security administrations the ability to remotely access systems for administration tasks, remediation actions or forensics collection, etc. without requiring physical access to the system. For more information on the CrowdStrike solution, see the additional resources and links below. In the Falcon UI, navigate to Activity > Detections. Commonly, a new detection will be the event that triggers a need for remediation.Directly from a given detection, the “Connect to Host” button allows you to remotely connect and take action. You can also connect to a host from Hosts > Host Management. Once connected, you will be presented with a list of commands and capabilities available in Real Time Response. With the ability to run commands, executables and scripts, the possibilities are endless. A few examples are listed below.

Top Commands Mostly Used By System Administrator. 1) IPconfig IPCONFIG Simply entering ipconfig at the command line will return basic addressing information for your system, including the adapter name, IP address, subnet mask, and default gateway. 2) IPconfig /all IPCONFIG/ALL Shows all networking information for the system, including host name, node type, adapter names, MAC addresses, DHCP lease information, etc. 3) Ping PING Ping command to verify that a host can be reached over the network. This command is useful for diagnosing host and network connectivity problems. The device sends a series of ICMP echo (ping) requests to a specified host and receives ICMP echo responses. 4) Ping "Website-name" PING TO WEBSITE   This above command used to find the IP address associated with The Specific Website. eg: 10.24.126.25 is the IP address for Website Intranet.indusind.com 5) Tracert "IP address" TRACE COMMAND Tracert comm

SECURITY OPERATION CENTRE

By Kunal Patil, Senior Threat Hunter

What is SOC?                    Security operations centers monitor and analyze activity on networks, servers, endpoints, databases, applications, websites, and other systems, looking for anomalous activity that could be indicative of a security incident or compromise. The SOC is responsible for ensuring that potential security incidents are correctly identified, analyzed, defended, investigated, and reported. SOC works with collaboration with People, Process and Technology.  SOC Architecture PEOPLE:                  The best way to think of a SOC is as a centralized team of people who provide threat monitoring, investigation, and response.  Larger SOCs employ a three-level analyst structure for handling security alerts generated by a security system or SIEM.  Level 1 analysts are responsible for real-time monitoring of security alerts, doing triage on them, and deciding whether an alert is serious enough to be escalated to a Level 2 analyst.  Level 1 analysts se

In Previous blog we learned how to setup CIFv3, in this section we will discuss how to integrate data and filter the Resulted Data by-passing different parameters to it. We might have question that what happens exactly after hitting cif command or how cifv3 fetches feeds from external resources. well in this blog i will cover every details of CIFv3 but before that lets study few terminologies to understands the implementation of this Project. CIFv3 uses few Terminologies like : 1) TLP TLP stands for Traffic Light Protocol originally created by UK government for the Purpose of sharing of sensitive data. There are four colors in TLP (same like traffic lights) : RED - Not for disclosure, restricted to participants only AMBER - Limited disclosure, restricted within own organisation and clients or customers. GREEN -  Limited disclosure, restricted to the community but not via public channels WHITE - Disclosure is not limited 2) Timestamps CIF supports three Times

Use Case  Falcon OverWatch has identified probable TrickBot malware on host NAOUXXXX. A renamed copy of Vhd2disk was executed on the host, likely from a successful phish. This in turn wrote and executed a malicious file, likely TrickBot malware, and established persistence for it with a registry key. Introduction  Emotet Often referred to as a banking trojan or worm. It is a very advanced threat that is updated multiple times a day by the cybercrooks controlling it. Emotet is an advanced, modular banking Trojan that primarily functions as a downloader or dropper of other banking Trojans. Additionally, Emotet is a polymorphic banking Trojan that can evade typical signature-based detection. It has several methods for maintaining persistence, including auto-start registry keys and services. It uses modular Dynamic Link Libraries (DLLs) to continuously evolve and update its capabilities. TrickBot TrickBot is most commonly installed by the Emotet Trojan, which is spread through phishing em
