Taiwan Chapter Status Report for 2010/2011


Taiwan Honeynet Chapter is founded in November 2008. Our mission is to assist in addressing the threats of information security in Taiwan.

Chapter Member:

  • Yi-Lang Tsai, Chapter Leader
  • Yu-Chin Cheng, Board of Director, Full Member
  • In this year, we plan to add more members and contributors. These members come from different universities, organizations or information security researcher.

    The following activities are made by our chapter:

    1. Malware behavior analysis and categories
    2. Abnormal traffic detection and analysis from network traffic flow
    3. Security operation center for incident management and handling
    4. Co-operation Taiwan academic information sharing and analysis center
    5. Huge data indexing and information mining technology
    6. Reverse engineering in malware analysis
    7. Digital Forensics about system and network analysis
    8. Collaboration with TWCERT/CC and leading honeynet working group to build Cyber Clean Center in Taiwan
    9. Rainbow table generators and hash cracks based on cloud computing or high-performance computing
    10. Botnet detection and behavior analysis


    1. Large-Scale Honeynet deployments
    • Get funding from National Science Council and Ministry of Education to establish large-scale honeynet in Taiwan Academic Network(TANet)
    • Build a lot of virtual honeynet in TANet and deployment of more than 3600 IP address.
    • Using Honeywall, Nepenthes, Dionaea, Kippo, Capture-HPC, HIHAT and security tools.
    • Using Splunk to analysis honeynet logs.
    • Information integration system design and development (Security Dashboard)

    2. Design malware analysis platform that is named TWMAN(TaiWan Malware Analysis Net) and release in Sourceforge(twman.sourceforge.net) and OpenFoundry(twman.openfoundry.org)
    3. Cloud-based vulnerability scanners and the evidence collection by network forensics technology
    4. Visualization framework for security analysis


    We are focused on honeynet deployments, malware collection, malware behavior analysis, botnet tracking, malware testbed and distributed data mining. The honeynet have collected a huge amount of data about automatic attack from malware. It is an important issue about botnet in Taiwan. We are trying to analysis malware samples and develop ontology inference for automatic malware analysis.

    1. TWMAN development

    Malware is an important topic of security threat research. In this project, a behavioral malware analysis system TWMAN is presented. This project focuses on using real operation system environment to analysis malware behavioral. Many researchers try to use virtual machine systems to monitor the malware behaviors. Those malware samples will only compromise the virtual operating system or virtual machine, which cannot reflect in the real operating system or real environment. Therefore, some malware researchers suggest that the malware sample should not be analyzed in virtual machine environment since the analyzer cannot gain much useful information in virtual machine environment.
    We developed a real operation system environment to analysis malware behavioral, named Taiwan Malware Analysis Net(TWMAN). In the following section, we explain how to use this real OS environment to analysis malware behavioral and describe the system structure of TWMAN briefly. In order to verify the correctness of analysis results obtained from TWMAN, we compare our analysis results with that from sandboxs, which are VM-based and real operation system analysis technique with CWSandbox of Sunbelt Software.

    2. Malwre testbed development

    The Taiwan Information Security Center(TWISC) was initiated as a research program in April 2005. Taiwan Information Security Center at National Cheng-Kung University ([email protected]) was officially founded on April 1st, 2006. We are using the testbed offered by [email protected] to develop malware testing platform in this year.

    3. Data mining technology development

    Based on our collection from our distributed honeynet, Splunk solution is used for generating search rules and reports. Some parsers are written by our programmers to analysis honeynet logs.

    4. Visualization security data

    We are testing DAVIX toolkit, Google earth API and Gephi for data visualization. Because the huge amount of data about 30 million events are captured by honeynet logs, we need to adopt the visualization technique for the presentation of security data. The source of security data is based on our security dashboard to daily record the security threats.

    Botnet Attack

    In the last year, TANet had been attacked by botnet from internet about 12.5 billion times. We have discovered that several IP addresses could be infected by more than three botnet malwares.

    Security threats

    Botnet is the most serious security threat in Taiwan since tons of computers in Taiwan are infected.

    Unique Malware Sample

    We are collected over 6000 unique malware samples from internet in this year. Our researchers focus on behavior-based malware analysis and use CWSandbox and TWMAN to analysis the malware samples from honeynet. We are planning to establish a malware knowledge database about malware behaviors for our own research and share them with information security researchers. The information will be shared with Government Information Sharing and Analyis Center (G-ISAC) and Malware Exchange System (MES) in Taiwan.

    The goal of our chapter is to develop honeynet in major campus in Taiwan and to deal with security incidents. In addition, we embark on the visualization for security data and the integration of information security analysis systems. The optimal vision is to reduce information security threats in the network environment of Taiwan.


    We are planning to hold an international workshop of Honeynet Project on October, 2011 in Taiwan. The first day is scheduled for technical and research presentations, and the second day is for hands-on training.
