This document discusses the challenges of software preservation and reproducibility in science and technology. It outlines how software is a key component of modern research but is fragile and can be lost. The state of software reproducibility in computer systems research is examined, finding that the majority of papers could not be reproduced. The Software Heritage project is introduced which aims to collect, organize, preserve and share all software to address these issues and support reproducibility. Open source software and replication are advocated for as important principles for software preservation platforms. Collaboration from the community is needed to integrate software preservation into development and publishing workflows while addressing legal and licensing issues.

When it comes to actual, real-world, active malware detection there are surprisingly few choices. Most companies invest in one anti-virus vendor and when they suspect a compromise they simply wait for them to issue signatures. If a company thinks they may be compromised but there is no AV signature, then what? What if we could use basic python scripting to identify malware based on signatures we produce in real time? There are plenty of python tools, scripts and frameworks for malware identification including yara, pefile, nsrl hash db, pyemu, hachoir, volatility and pyew. What if we could integrate these together into a system for centrally issuing indicators of compromise? What if hosts we suspect as being compromised used this system to check themselves for compromise? Lets find out...

FuzzyDbg is a debugger that integrates fuzzing and execution tracing functionality. It generates mutated inputs to test programs and identify crashes. When a crash occurs, it saves the crashing input and execution trace which details the functions triggered prior to the crash. This provides more information for analyzing crashes than a typical debugger. It aims to reduce performance overhead during tracing and provide a one-stop debugging solution.

The document discusses a smart fuzzer tool that can automatically generate test cases to test applications by providing semi-valid or corrupted input files. It specifically describes a smart fuzzer for PNG image files that understands the PNG file format and can selectively corrupt chunks like IHDR, pHYs and other common chunks. The smart fuzzer aims to test application robustness by detecting crashes or abnormal behavior when handling invalid input. It also discusses how fuzzing tools can range from simple to more advanced ones that virtualize file streams for fuzz testing at scale.

Abstract-Software is ubiquitous in our daily life. It brings us great convenience and a big headache about software reliability as well: Software is never bug-free, and software bugs keep incurring monetary loss of even catastrophes. In the pursuit of better reliability, software engineering researchers found that huge amount of data in various forms can be collected from software systems, and these data, when properly analyzed, can help improve software reliability. Unfortunately, the huge volume of complex data renders the analysis of simple techniques incompetent; consequently, studies have been resorting to data mining for more effective analysis. In the past few years, we have witnessed many studies on mining for software reliability reported in data mining as well as software engineering forums. These studies either develop new or apply existing data mining techniques to tackle reliability problems from different angles. In order to keep data mining researchers abreast of the latest development in this growing research area, we propose this paper on data mining for software reliability. In this paper, we will present a comprehensive overview of this area, examine representative studies, and lay out challenges to data mining researchers.

This document discusses using data mining techniques to improve software maintenance and reliability. It provides an overview of applying techniques like classification, association rule mining, and clustering to mine software engineering data from code bases, change histories, and bug reports. Specifically, it describes mining frequent patterns and rules from source code and revision histories to detect bugs as deviations from these patterns. A methodology is presented that involves parsing source code to build an itemset database, applying frequent itemset mining to extract programming patterns and rules, and detecting violations of rules as potential bugs. Challenges and limitations of these approaches are also discussed.

SHIELDEXTM is a solution that uses content disarm and reconstruction (CDR) technology to sanitize incoming external files by removing potentially malicious code and reconstructing only approved contents, in order to protect against advanced persistent threats (APTs) in a way that existing security methods cannot. The solution scans file structures, applies CDR technology, and provides logging and reporting while allowing only safe documents internally through various network access points.

This document provides an overview and outline for a research project titled "Finding Forensic Artifacts From Window Registry". The research aims to analyze the Windows Registry to find forensic artifacts from USB devices and unauthorized access. The summary provides background on the structure and contents of the Windows Registry. It also outlines some open problems regarding artifacts left in the Registry when USB devices are connected. The proposed solution will analyze specific locations in the Registry related to USB and other forensic artifacts. This research aims to build upon prior work by providing a deeper analysis of USB device identifiers and Registry locations beyond just installation locations.

The document discusses the challenges of preserving software to ensure reproducibility in science. It notes that 81% of computer science papers studied were found to be non-reproducible due to a lack of available source code and documentation. Preserving software is complex as it often has dependencies on other software and hardware. However, software embodies much of our scientific and technical knowledge, so efforts must be made to preserve and provide access to source code in order to establish reproducibility as the foundation of scientific inquiry.

"Keynote - Preserving Software: Challenges and Opportunities for Reproducibility of Science and Technology" By Roberto Di Cosmo, Irill for ScilabTEC 2015

It started with computer hacking and Japanese linguistics as a kid. Zach Mathis has been based in Kobe, Japan, and has performed both red team services as well as blue team incident response and defense consultation for major Japanese global Japanese corporations since 2006. He is the founder of Yamato Security, one of the largest and most popular hands-on security communities in Japan, and has been providing free training since 2012 to help improve the local security community. Since 2016, he has been teaching security for the SANS institute and holds numerous GIAC certifications. Currently, he is working with other Yamato security members to provide free and open-source security tools to help security analysts with their work.

An expert in mobile network security provided a summary of hacking 5G networks. Some key points include: 1) Standard IT security techniques uncovered issues when applied to upgraded legacy 4G networks, such as unpatched operating systems, weak configurations, and lack of encryption. 2) Future 5G networks introduce new security risks due to increased complexity from virtualization and automation layers, as well as a continuously evolving attack surface extending into cloud infrastructure. 3) Red team exercises show that hacking mobile networks has become a multi-step process, where initial access through one vulnerability can enable lateral movement and privilege escalation to compromise critical systems or customer data.

Printer has become one of the essential devices in the corporate intranet for the past few years, and its functionalities have also increased significantly. Not only print or fax, cloud printing services like AirPrint are also being supported as well to make it easier to use. Direct printing from mobile devices is now a basic requirement in the IoT era. We also use it to print some internal business documents of the company, which makes it even more important to keep the printer safe. Nowadays, most of the printers on the market do not have to be connected with USB or traditional cable. As long as you are using a LAN cable connected to the intranet, the computer can find and use the printer immediately. Most of them are based on protocols such as SLP and LLMNR. But is it really safe when vendors adopt those protocols? Furthermore, many printers do not use traditional Linux systems, but use RTOS(Real-Time Operating System) instead, how will this affect the attacker? In this talk, we will use Canon ImageCLASS MF644Cdw and HP Color LaserJet Pro MFP M283fdw as case study, showing how to analyze and gain control access to the printer. We will also demonstrate how to use the vulnerabilities to achieve RCE in RTOS in unauthenticated situations.

While hackers have known the importance of sharing research to improve security for years, the importance of coordinated vulnerability disclosure is increasingly recognized by governments around the world. The principals of disclosure an protecting security researchers are common across borders, but different countries have some key differences. This panel will present a global perspective that may in turn inform key public policy and company behavior. ENISA has published 'Coordinated Vulnerability Disclosure policies in the EU' in April 2022 . This report not only provides an objective introduction to the current state of coordinated vulnerability disclosure policies in the Member States of the European Union, but also introduces the operation of vulnerability disclosure in China, Japan and the USA. Based on these findings, the desirable and good practice elements of a coordinated vulnerability disclosure process are examined, followed by a discussion of the challenges and issues. This session aims to share the contents of this report and clarify the challenges and future direction of operations in Japan, as well as national security and vulnerability handling issues in the US, in a panel discussion with representatives from various jurisdictions. The panelists are involved in the practice of early warning partnership notified bodies in Japan, the authors of the above report in Europe and the contributors to the above report in the US. In Japan, the issues of system awareness, incentives, increase in the number of outstanding cases in handling and so-called triage in handling vulnerabilities will be introduced. From the United States, the Vulnerabilities Equities Process for National Security and the publication of a non-prosecution policy for vulnerability research will be introduced, as well as a historical background on the issue. The aim is that the panel discussion will enable the audience to understand the international situation surrounding CVD, as well as future trends, in particular the important role of vulnerability in cybersecurity and the challenges faced by society around it.

ハッカーたちの間では、セキュリティ向上のために研究を共有することの重要性が何年も前から知られていた。一方、協調して脆弱性を開示することの重要性も、世界中の政府によってますます認識されるようになってきた。情報開示とセキュリティ研究者の保護という原則は国境を越えて共通であるものの、国によって重要な違いがある。本パネルでは、重要な公共政策や企業の行動に影響を与える可能性のあるグローバルな視点を提示する。 ENISAは、2022年4月に「EUにおける脆弱性開示政策の調整」を発表した。本報告書では、EU加盟国における脆弱性開示の協調政策の現状を客観的に紹介するだけでなく、中国、日本、米国における脆弱性開示の運用を紹介している。それらを踏まえて、協調的な脆弱性開示プロセスに望ましい要素やベストプラクティスの要素を検討し、その後、課題や問題点について議論する予定。 本報告書の内容を共有し、日本における運用の課題と今後の方向性、米国における国家安全保障と脆弱性対応の課題を、各法域の代表者とのパネルディスカッションで明らかにすることを目的としています。 パネリストは、日本では早期警戒パートナーシップ通知機関の実務に携わる方々、欧州では上記報告書の執筆者、米国では上記報告書の寄稿者 日本では、脆弱性対応における体制意識、インセンティブ、未処理案件の増加、いわゆるトリアージなどの課題が紹介される予定 米国からは、国家安全保障のための脆弱性情報の開示方針（Vulnerabilities Equities Process）、脆弱性研究の不起訴方針の公表などを紹介するとともに、この問題の歴史的背景を紹介する。 パネルディスカッションを通じて、脆弱性開示政策を取り巻く国際情勢や今後の動向、特にサイバーセキュリティにおける脆弱性の重要な役割とそれを取り巻く社会が抱える課題について参加者に理解していただくことを目的とする。

2021年10月、Lazarusグループに関連する可能性が高いユニークなローダーであるWSLinkの最初の分析を公開。ほとんどのサンプルは難読化され、高度な仮想マシン（VM）難読化機能で保護されている。サンプルには明確なアーティファクトが含まれておらず、当初は難読化を公的に知られているVMと関連付けなかったが、後にそれをCodevirtualizerに接続することに成功。このVMは、ジャンクコードの挿入、仮想オペランドの暗号化、仮想オペコードの重複、難読化手法仮想命令のマージ、ネストされたVMなど、いくつかの追加の難読化技術を導入する。 本発表では、VMの内部を分析し、合理的な時間で難読化技術を「見抜く」ための半自動化されたアプローチについて説明する。また、難読化されたバイトコードと難読化されていないバイトコードを比較し、本手法の有効性を紹介する。われわれの手法は、仮想オペコードのセマンティクスを抽出する既知の難読化解除手法に基づいており、単純化規則によるシンボリック実行を使用。さらに、バイトコードチャンクとVMの内部構成を記号ではなく、具体的な値として扱い、既知の難読化手法で追加の難読化技術を自動的に処理できるようにする。

In October 2021, we published the first analysis of Wslink – a unique loader likely linked to the Lazarus group. Most samples are packed and protected with an advanced virtual machine (VM) obfuscator; the samples contain no clear artifacts and we initially did not associate the obfuscation with a publicly known VM, but we later managed to connect it to CodeVirtualizer. This VM introduces several additional obfuscation techniques such as insertion of junk code, encoding of virtual operands, duplication of virtual opcodes, opaque predicates, merging of virtual instructions, and a nested VM. Our presentation analyzes the internals of the VM and describes our semi automated approach to “see through” the obfuscation techniques in reasonable time. We demonstrate the approach on some bytecode from a protected sample and compare the results with a non-obfuscated sample, found subsequent to starting our analysis, confirming the method’s validity. Our solution is based on a known deobfuscation method that extracts the semantics of the virtual opcodes, using symbolic execution with simplifying rules. We further treat the bytecode chunks and some internal constructs of the VM as concrete values instead of as symbolic ones, enabling the known deobfuscation method to deal with the additional obfuscation techniques automatically.

Kimsuky is a North Korean APT possibly controlled by North Korea's Reconnaissance General Bureau. Based on reports from the Korea Internet & Security Agency (KISA) and other vendors, TeamT5 identified that Kimsuky's most active group, CloudDragon, built a workflow functioning as a "Credential Factory," collecting and exploiting these massive credentials. The credential factory powers CloudDragon to start its espionage campaigns. CloudDragon's campaigns have aligned with DPRK's interests, targeting the organizations and key figures playing a role in the DPRK relationship. Our database suggested that CloudDragon has possibly infiltrated targets in South Korea, Japan, and the United States. Victims include think tanks, NGOs, media agencies, educational institutes, and many individuals. CloudDragon's "Credential Factory" can be divided into three small cycles, "Daily Cycle," "Campaign Cycle," and "Post-exploit Cycle." The"Daily Cycle" can collect massive credentials and use the stolen credentials to accelerate its APT life cycle. In the "Campaign Cycle," CloudDragon develops many new malware. While we responded to CloudDragon's incidents, we found that the actor still relied on BabyShark malware. CloudDragon once used BabyShark to deploy a new browser extension malware targeting victims' browsers. Moreover, CloudDragon is also developing a shellcode-based malware, Dust. In the "Post-exploit Cycle," the actor relied on hacking tools rather than malicious backdoors. We also identified that the actor used remote desktop software to prevent detection. In this presentation, we will go through some of the most significant operations conducted by CloudDragon, and more importantly, we will provide possible scenarios of future invasions for defense and detection.

Social media is no doubt a critical battlefield for threat actors to launch InfoOps, especially in a critical moment such as wartime or the election season. We have seen Bot-Driven Information Operations (InfoOps, aka influence campaign) have attempted to spread disinformation, incite protests in the physical world, and doxxing against journalists. China's Bots-Driven InfoOps, despite operating on a massive scale, are often considered to have low impact and very little organic engagement. In this talk, we will share our observations on these persistent Bots-Driven InfoOps and dissect their harmful disinformation campaigns circulated in cyberspace. In the past, most bots-driven operations simply parroted narratives of the Chinese propaganda machine, mechanically disseminating the same propaganda and disinformation artifacts made by Chinese state media. However, recently, we saw the newly created bots turn to post artifacts in a livelier manner. They utilized various tactics, including reposting screenshots of forum posts and disguised as members of “Milk Tea Alliance,” to create a false appearance that such content is being echoed across cyberspace. We particularly focus on an ongoing China's bots-driven InfoOps targeting Taiwan, which we dub "Operation ChinaRoot." Starting in mid-2021, the bots have been disseminating manipulated information about Taiwan's local politics and Covid-19 measures. Our further investigation has also identified the linkage between Operation ChinaRoot and other Chinese state-linked networks such as DRAGONBRIDGE and Spamouflage.

Malwares written in Go is increasing every year. Go's cross-platform nature makes it an opportune language for attackers who wish to target multiple platforms. On the other hand, the statically linked libraries make it difficult to distinguish between user functions and libraries, making it difficult for analysts to analyze. This situation has increased the demand for Go malware classification and exploration. In this talk, we will demonstrate the feasibility of computing similarity and classification of Go malware using a newly proposed method called gimpfuzzy. We have implemented "gimpfuzzy", which incorporates Fuzzy Hashing into the existing gimphash method. In this talk, we will verify the discrimination rate of the classification using the proposed method and confirm the validity of the proposed method by discussing some examples from the classified results. We will also discuss issues in Go-malware classification.

Goで書かれたマルウェアは年々増加している。Goはクロスプラットフォームの性質を持っており、複数のプラットフォームを標的にしたい攻撃者にとって好都合な言語である。その一方で、ライブラリが静的にリンクされていることからユーザ関数とライブラリの区別が難しく、アナリストにとって解析が困難である。そうした状況で、Goマルウェアの分類や探索の需要が高まっている。 本講演ではgimpfuzzyという新たな提案手法を用いてGoマルウェアに対し類似性の計算や分類が可能であることを検証する。われわれは既存手法であるgimphashにFuzzy Hashingを組み込んだ「gimpfuzzy」を新たに実装した。講演では提案手法を利用した分類の判別率を検証し、分類された結果の中からいくつかの事例を取り上げその妥当性について確認する。また、Goマルウェアの分類における課題についても検討を行う予定である。

This document discusses the results of long-term scanning and analysis of Winnti 4.0 and ShadowPad malware command and control (C2) protocols. It finds that Winnti 4.0 C2s primarily use TLS, HTTPS, and HTTP, while ShadowPad variants primarily use TCP, HTTPS, and HTTP. Analysis of the protocols reveals encryption methods, packet structures, and server-side functionality. Over time, the number and distribution of active C2s changed, likely in response to research publications and incident response actions. The document advocates for anonymization techniques and merits and risks of future research publications.

We are swamped with new types of malware every day. The goal of malware analysis is not to reveal every single detail of the malware. It is more important to develop tools for efficiency or introduce automation to avoid repeating the same analysis process. Therefore, malware analysts usually actively develop tools and build analysis systems. On the other hand, it costs a lot for such tool developments and system maintenance. Incident trends change daily, and malware keeps evolving. However, it is not easy to keep up with new threats. Malware analysts spend a long time maintaining their analysis systems, and it results in reducing their time for necessary analysis of new types of malware. To solve these problems, we incorporate DevOps practices into malware analysis to reduce the cost of system maintenance by using CI/CD and Serverless. This presentation shares our experience on how CI/CD, Serverless, and other cloud technologies can be used to streamline malware analysis. Specifically, the following case studies are discussed. * Malware C2 Monitoring * Malware Hunting using Cloud * YARA CI/CD system * Malware Analysis System on Cloud * Memory Forensic on Cloud Through the above case studies, we will share the benefits and tips of using the cloud and show how to build a similar system using Infrastructure as Code (IaC).

Stream processing is a crucial component of modern data infrastructure, but constructing an efficient and scalable stream processing system can be challenging. Decoupling compute and storage architecture has emerged as an effective solution to these challenges, but it can introduce high latency issues, especially when dealing with complex continuous queries that necessitate managing extra-large internal states. In this talk, we focus on addressing the high latency issues associated with S3 storage in stream processing systems that employ a decoupled compute and storage architecture. We delve into the root causes of latency in this context and explore various techniques to minimize the impact of S3 latency on stream processing performance. Our proposed approach is to implement a tiered storage mechanism that leverages a blend of high-performance and low-cost storage tiers to reduce data movement between the compute and storage layers while maintaining efficient processing. Throughout the talk, we will present experimental results that demonstrate the effectiveness of our approach in mitigating the impact of S3 latency on stream processing. By the end of the talk, attendees will have gained insights into how to optimize their stream processing systems for reduced latency and improved cost-efficiency.

If you’ve ever had to analyze a map or GPS data, chances are you’ve encountered and even worked with coordinate systems. As historical data continually updates through GPS, understanding coordinate systems is increasingly crucial. However, not everyone knows why they exist or how to effectively use them for data-driven insights. During this webinar, you’ll learn exactly what coordinate systems are and how you can use FME to maintain and transform your data’s coordinate systems in an easy-to-digest way, accurately representing the geographical space that it exists within. During this webinar, you will have the chance to: - Enhance Your Understanding: Gain a clear overview of what coordinate systems are and their value - Learn Practical Applications: Why we need datams and projections, plus units between coordinate systems - Maximize with FME: Understand how FME handles coordinate systems, including a brief summary of the 3 main reprojectors - Custom Coordinate Systems: Learn how to work with FME and coordinate systems beyond what is natively supported - Look Ahead: Gain insights into where FME is headed with coordinate systems in the future Don’t miss the opportunity to improve the value you receive from your coordinate system data, ultimately allowing you to streamline your data analysis and maximize your time. See you there!
