    摘要： A method for generating a cross-site scripting attack is provided. An attack string sample is analyzed for obtaining a token sequence. A string word corresponding to each token is used to replace the token for generating a cross-site scripting attack string. Accordingly, a large number of cross-site scripting attacks are generated automatically, so as to execute a penetration test for a website.

    摘要： A method for detecting a malicious script is provided. A plurality of distribution eigenvalues are generated according to a plurality of function names of a web script. After the distribution eigenvalues are inputted to a hidden markov model (HMM), probabilities respectively corresponding to a normal state and an abnormal state are calculated. Accordingly, whether the web script is malicious or not can be determined according to the probabilities. Even an attacker attempts to change the event order, insert a new event or replace an event with a new one to avoid detection, the method can still recognize the intent hidden in the web script by using the HMM for event modeling. As such, the method may be applied in detection of obfuscated malicious scripts.

    摘要翻译： 提供了一种用于检测恶意脚本的方法。 根据web脚本的多个功能名称生成多个分布特征值。 在将分布特征值输入到隐马尔可夫模型（HMM）之后，计算分别对应于正常状态和异常状态的概率。 因此，可以根据概率来确定web脚本是否是恶意的。 即使攻击者也尝试更改事件顺序，插入新事件或替换事件以避免检测，该方法仍然可以通过使用HMM进行事件建模来识别隐藏在Web脚本中的意图。 因此，该方法可以应用于检测模糊的恶意脚本。

    摘要： A botnet detection system is provided. A bursty feature extractor receives an Internet Relay Chat (IRC) packet value from a detection object network, and determines a bursty feature accordingly. A Hybrid Hidden Markov Model (HHMM) parameter estimator determines probability parameters for a Hybrid Hidden Markov Model according to the bursty feature. A traffic profile generator establishes a probability sequential model for the Hybrid Hidden Markov Model according to the probability parameters and pre-defined network traffic categories. A dubious state detector determines a traffic state corresponding to a network relaying the IRC packet in response to reception of a new IRC packet, determines whether the IRC packet flow of the object network is dubious by applying the bursty feature to the probability sequential model for the Hybrid Hidden Markov Model, and generates a warning signal when the IRC packet flow is regarded as having a dubious traffic state.

    摘要： A citation record extraction system is provided for extracting citation records from publication list pages having different layouts and contents. An HTML rendering engine receives a publication list web page, parses the publication list web page to obtain layout information of the web page. A web page sequence builder generates a web page characteristic sequence for the web page according to the layout information. A web page repeated pattern analyzer analyzes repeated patterns presented in the web page characteristic sequence, screens out non-citation records therefrom, and obtains a citation record of the publication list web page.
