RTR using Falcon Crowdstrike

By Kunal Patil, Senior Threat Hunter

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.

SECURITY OPERATION CENTRE

By Kunal Patil, Senior Threat Hunter
Image
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

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

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

TrickBot Malware Family - A Deep Dive using Falcon Crowdstrike

By Kunal Patil, Senior Threat Hunter
Image
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
