Deep Dive into Active Directory(AD) Attack Techniques
Mars Cheng [TW]
For either On-Premises, Hybrid, or Azure environments, Microsoft Active Directory (AD) is widely used by enterprises as a backbone for identity and access management. AD is recognized by adversaries for providing access to a company's crown jewels. Although AD has critical functionalities for enterprise operation, attackers can abuse these mechanisms provided by AD services to compromise an enterprise network to achieve their operations.
In this training course, we will deep dive into On-Premises exploring different kinds of AD services and technologies. We will cover various AD attack techniques by abusing the underlying mechanisms. This course is expected to be lab-intensive with over 5 hands-on practices. For each training lab, there will be an in-depth discussion as a core concept to enable the student to understand the theoretical background and effectively implement an attack technique.

How (not) to build a vulnerable LLM web app
Shota Shinogi [JP]
Since OpenAI released the ChatGPT API (to be more specific; Completion API), the era of LLM integrated system has come. Many companies build chatbot, or more complex web applications, to guide the user, or to perform some business operation, identifiing malware. Then a new hacking technique "Prompt Injection" was born.
The session will cover how to build a system with LLM, then the hacking technique related to LLM; jailbreak to bypass the safeguard of LLM, prompt leaking to steal the prompt, prompt injection to manipulate the LLM result, and more attack method to finally compromise the whole LLM integrated web app.
Shota Shinogi is a security researcher at Macnica, pentest tools author and CTF organizer. He is an expert in writting malware for Red Team purpose and to evade the detection from EDR, sandbox, IPS, antivirus and other security solutions.

Handling Threat Intelligence: Techniques of consuming and creating threat intelligence
Tomohisa Ishikawa [JP]
To prevent advanced threat actors from compromising systems and mitigate similar attacks, it is crucial to employ threat intelligence. This involves the collection, analysis, and dissemination of diverse information regarding threat actors and their Tactics, Techniques, and Procedures (TTPs). Effective prevention and detection rely heavily on this practice. Additionally, by sharing analyzed and generated threat intelligence both within and beyond the organization, we can enhance early warning mechanisms for the industry and cybersecurity communities.
When discussing the "analysis of attack", security engineers typically think of techniques such as malware analysis, vulnerability assessment, and forensics. However, a fundamental question arises: How can we effectively utilize the outcomes of technical analysis to enhance prevention and detection efforts?
In this lecture, we will explore three key areas. Firstly, we will delve into the foundational principles of threat intelligence theory, covering various concepts such as the types of intelligence, the threat intelligence cycle, and attribution. Secondly, we will focus on analysis techniques and the practical application of threat intelligence. Drawing from information obtained through activities like malware analysis and forensic analysis, we will learn how to leverage frameworks like MITRE ATT&CK to comprehend TTPs. We will also explore how to apply this knowledge to threat hunting, purple teaming, and discussions regarding countermeasures. In the third part of the lecture, we will explore the process of translating this acquired threat intelligence into actionable prevention and detection measures. This will involve learning about the creation of Indicators of Compromise (IOCs) using tools such as YARA and SIGMA.

Additionally, he has authored a book on threat intelligence in Japanese and has translated four DFIR books and one API security book from O'Reilly Japan.
Fuzzing in the kernel world
Yi-Han Wang [TW]
Fuzzing is an important tool for finding out security bugs automatically. Today, the lecturer will primarily focus on system-level fuzzing, as implementation bugs at this level can cause severe and disastrous consequences.
The course will begin with a thorough overview of general fuzzers, followed by an introduction to virtualization and system-level fuzzers. Throughout the course, the lecture will explain the concept and motivate participants to conduct their own tests using fuzzers. The aim is for everyone to gain a comprehensive understanding of fuzzing technology and its practical applications.
