Integrating Threat Intelligence with CSIRT Procedure to Increase Efficiency of Incident Response: Malaysia CERT Experience
Technical Level (3 being the highest score): 2

Incident Response procedures may not be comprehensive enough to address complex and sophisticated incidents nowadays. The ever-increasing scale, complexity and globalization of cyber attacks require quick detection, accurate analytics and eradication of the attacks. Hense, a more practical procedure and pro-active approach to fulfill this quest is necessary, which is the focus of the presentation.

The presentation helps to overcome limitations of CSIRT like:

➢ Lack of accuracy and precision of incident detection resulting in undetected incidents in an organization
➢ Time limitation in incident handling affects immediate mitigations of attacks at global level
➢ CSIRT procedures do not cover the scope of understanding attack vectors and threat actor information

A case study related to multiple IP addresses originating from Malaysia that belongs to a single network operator will be highlighted, involved in several large-scale cyber attacks around the world such as data leakage, espionage, commercial fraud and malware activities. In this case study we will show how we identified the Indicators of Compromise, Tactics, Techniques and Procedures, and the Threat Actors and how this information helped in the successful investigation of this incident.

The key points in this presentation are:

➢ The important roles of CSIRTs, CERTs and PSIRTs in eradicating and mitigating large-scale cyber attacks at global level via means of Threat Intelligence
➢ Share our integration workflow that illustrates how Threat Intelligence is delivered in the investigation of an incident for quick and efficient Incident Response, which focuses on a case study of Malaysian IP addresses involved in global large-scale attacks
➢ Share our in-house developed tools and applications that we used for the investigation of this incident
➢ Share our in-house developed tools and tips on customizing existing tools for enhancement and improvement of the Threat Intelligence delivery for effective mitigation of global cyber attacks
