摘要： A data transmission subsystem, operably coupled to the bar code reading engine, communicates such symbol character data to the communication interface of a host system over a communication link therebetween. The data transmission subsystem implements a plurality of different communication interfaces. During an interface configuration mode of operation, the data transmission subsystem is able to automatically configure itself such that its interface is suitable for communication to the communication interface of the host system. Moreover, the device is thus capable of interfacing to a variety of different host devices in an automatic and error free manner with minimal human involvement, thus providing significant advantages over the prior art bar code symbol reading devices.

摘要： One embodiment relates to a computer-implemented method for detecting malicious scripts in web pages. A local engine and an application are executed at a client computer. The local engine intercepts an access by the application to a web page at a universal resource locator (URL) under a domain. The local engine determines scripts at the URL and scripts at other URLs under the domain. Using that information, the local engine determines if the scripts at the URL include one or more unique script(s). The local engine sends the unique script(s), if any, via a network to a script analyzer. The script analyzer may then perform emulation of the unique script(s) to detect malicious code therein. Other embodiments, aspects and features are also disclosed.

摘要： Cross-site scripting vulnerabilities in a Web browser that may lead to malware execution on a computing device are reduced. The specific vulnerabilities arise from HTML-based e-mails using e-mail service providers (e.g., Hotmail, Gmail, Yahoo) that have unknown or malformed HTML elements and Javascripts. These unknown elements may execute in a browser and cause harm to the computing device. To prevent this, the e-mail is parsed to create a DOM tree. The DOM tree is filtered using a normal element filter. The modified DOM tree is filtered a second time using a script analyzer filter to isolate potentially harmful HTML and Javascript elements. These elements are then emulated to determine which of them are in fact malicious. These malicious elements are then prevented from executing, for example, by preventing the e-mail recipient from opening the e-mail in the browser.
摘要翻译： Web浏览器中可能导致计算设备上恶意软件执行的跨站点脚本漏洞减少。特定的漏洞源自使用电子邮件服务提供商（例如Hotmail，Gmail，Yahoo）的HTML电子邮件，其中包含未知或格式错误的HTML元素和Javascript。这些未知元素可能在浏览器中执行，并对计算设备造成危害。为了防止这种情况，电子邮件被解析为创建一个DOM树。使用普通元素过滤器过滤DOM树。修改后的DOM树第二次使用脚本分析器过滤器进行过滤，以隔离可能有害的HTML和Javascript元素。然后将这些元素模拟以确定其中哪些实际上是恶意的。然后，例如通过防止电子邮件接收者在浏览器中打开电子邮件来防止这些恶意元素的执行。

摘要： A machine learning model is used to identify normal scripts in a client computer. The machine learning model may be built by training using samples of known normal scripts and samples of known potentially malicious scripts and may take into account lexical and semantic characteristics of the sample scripts. The machine learning model and a feature set may be provided to the client computer by a server computer. In the client computer, the machine learning model may be used to classify a target script. The target script does not have to be evaluated for malicious content when classified as a normal script. Otherwise, when the target script is classified as a potentially malicious script, the target script may have to be further evaluated by an anti-malware or sent to a back-end system.
摘要翻译：机器学习模型用于识别客户端计算机中的正常脚本。机器学习模型可以通过使用已知正常脚本的样本和已知潜在恶意脚本的样本的训练来构建，并且可以考虑示例脚本的词汇和语义特征。机器学习模型和特征集可以由服务器计算机提供给客户端计算机。在客户端计算机中，机器学习模型可用于对目标脚本进行分类。当分类为普通脚本时，目标脚本不必对恶意内容进行评估。否则，当目标脚本被分类为潜在的恶意脚本时，目标脚本可能必须由反恶意软件进一步评估或发送到后端系统。

摘要： An application document known to include malware (such as a document exploit) is opened and executed by its corresponding software application. Behaviors of this document (such as registry, file system, network and process) are monitored and recorded using internal software drivers and hook modules. A behavior report is generated and a baseline pattern is created including a number of regular expressions. A suspicious document of the same type as the monitored document is opened and executed by the same corresponding software application. Behaviors are monitored in the same way and a behavior report is generated. This behavior report is compared to the baseline pattern and a determination is made as to whether a document exploit is present. Known benign documents may also be opened, monitored and their behavior recorded, resulting in creation of a known benign pattern for the corresponding software application.

摘要： A Web browser or operating system of a computer maintains a historical URL list of Web sites and Web pages that have been accessed in the past. When a prescan module of antivirus software performs an initial prescan of a computer before the antivirus software is installed, it queries this historical URL list to obtain the URLs that have been accessed in the past. These URLs are sent to a URL online query service located remotely over the Internet in order to determine the status of any of these URLs. Each URL is attempted to be matched with a database of known malicious URLs including associated malicious files and associated cleanup patterns. The query service then informs the requesting computer of the status of a particular URL sent, sending back any related malicious files and any appropriate cleanup pattern. A time period associated with each URL in the database indicates when it is known that the URL was malicious.
