Hackathon of PowerShell Malware Detection Engine

Trainer: Shota Shinogi [JP]


PowerShell based malware is everywhere. It is often executed from Office macro or shortcut(LNK) or exploit + shellcode. The functionality can vary but we observed the powershell script used as a stager to download or extract the next malware a lot, and sometimes as backdoor or ransomware. The attackers use the PowerShell because it is a default tools on Windows and the script can be run without touching the file system; file-less. And the most important part is that there are hundreds way to obfuscate the script to make the detection harder.

Microsoft is fighting against those malicious PowerShell with AMSI (AntiMalware Scan Interface) but the attackers always use bypass techniques.

The training will start with some lecture about basics of PowerShell and its obfuscation techniques. Then the attendess will split into small groups and get asked to write a detection engine using the PowerShell logging feature of Windows by Python. The attendees will start with considering the methodology to detect the malicious script. For example, it can be pattern match / black-listed API, symbols-alphanumeric frequency rates, or even AI based text detection engine. Any methodology will be welcomed as long as the attendees can build it. The last part of the training will be a competition, which detection engine is the best. Each group will bring their detection engine and we will measure the detection rate using malware samples.

Reverse Engineering Malware Written in C++ with IDA and Semi-Automated Scripts

Trainer: Hiroshi Suzuki / Hisao Nashiwa [JP]


C++ is widely used in a variety of malware, such as RATs and banking Trojans, etc. Malware written in C++ is often object-oriented. Analyzing it requires knowledge and experience with classes and their inheritance, vtable, and basic strings, in addition to knowledge of analyzing malware written in C. In this course, attendees will learn how to quickly find and deal with such features.

In this course, we will use IDA Free for analysis. Although Ghidra, which is popular among CTF players these days, is useful for analyzing simple and/or small programs, and under certain conditions, it is still inferior to IDA in many aspects, such as processing speed, decompiler accuracy, and a variety of third-party scripts and plug-ins. IDA is still the de facto standard reverse engineering tool.

In this course, while learning how to use IDA, we will analyze actual malware written in C++, and aim to learn the techniques including the know-how. Afterwards, we will practice the techniques we have learned through CTF-style games, having fun, cooperating and competing with each other.

Hypervisor 101 in Rust

Trainer: Satoshi Tanda [JP]


In this class, we will learn the basics of hardware-assisted virtualization technologies on x86 through writing a custom hypervisor in Rust for kernel-code fuzzing.

Hardware-assisted virtualization such as Intel VT-x and AMD-V is the technology that enables today’s many workloads, including cloud computing, isolated software development and validation, and security research. While the understanding of “how it works” is essential for auditing such solutions as well as using the technology for creative purposes, gaining knowledge and experience in this domain is often challenging due to its low-level nature.

Given that, this course will offer the basic knowledge of how hypervisors realize the concept of “VMs”, and as an application of the concept, hands-on experiences in implementing the snapshot-based fuzzer that runs a target as a VM. The hands-on exercises include learning VMCS/VMBC, EPT/NTP, exception interception as well as debugging of CPU itself using Bochs.

With knowledge acquired by this course, the most successful students would discover 0-day vulnerabilities in non-user-mode software such as kernel and UEFI modules by extending their hypervisors or effectively using similar fuzzers such as WTF with the understanding of underneath technology.

Web Tracking and Browser Fingerprinting

Trainer: Kai-Hsiang Chou [TW]


Web tracking is the technique of assigning each user a distinct identifier so that future visits from the same users, whether or not to the same websites, may be recognized and linked. While web tracking techniques have some legitimate usages, they are often used in privacy-intrusive ways, such as profiling and ad targeting. In the early days, many advertisers and website owners relied on stateful tracking techniques. Recently, many have adopted stateless techniques, especially browser fingerprinting, due to their effectiveness and difficulties in blocking them. By running a script to collect browser-specific data, one may identify and track the users without storing any stateful identifiers. This training will introduce several common and novel web tracking techniques, including stateful tracking and browser fingerprinting, their mitigations, and open challenges. We will also discuss some progress in privacy-preserving web tracking.
