摘要： This document describes techniques for detection of code-based malware. According to some embodiments, the techniques utilize a collection of known malicious code and know benign code and determine which features of each type of code can be used to determine whether unclassified code is malicious or benign. The features can then be used to train a classifier (e.g., a Bayesian classifier) to characterize unclassified code as malicious or benign. In at least some embodiments, the techniques can be used as part of and/or in cooperation with a web browser to inspect web content (e.g., a web page) to determine if the content includes code-based malware.

摘要： Techniques for execution of multiple execution paths are described. In one or more embodiments, an execution of a portion of executable code is conditioned upon a particular environment-specific value. For example, the execution of the executable code can cause one type of output if the value of the variable equals a particular value, and can cause a different type of output if the value of the variable equals a different value. Techniques discussed herein can enable the executable code to be executed such that multiple outputs are produced, e.g., by executing the code according to the different values for the variable. In implementations, the multiple outputs can be analyzed for various attributes, such as presence of malware, implementation and coding errors, and so on.

摘要： A method described herein includes at a computing device, receiving, over a network connection, a data packet from an external source, wherein the data packet comprises a compressed abstract syntax tree (AST)-based representation of source code written in a scripting language. The method further includes decompressing the compressed AST-based representation of the source code to generate a decompressed AST. The method also includes causing at least one processor on the computing device to execute at least one instruction represented in the decompressed AST subsequent to the compressed AST-based representation of the source code being decompressed.

摘要： Data formatting rules to convert data from one form to another form are automatically determined based on a user's edits. A machine learning heuristic is applied to a user's edits to determine a data formatting rule that may be applied to data. For example, a user may make edits that add/remove characters from data, concatenate data, extract data, rename data, and the like. The machine learning heuristic may be automatically triggered in response to an event (e.g. after a predetermined number of edits are made to a same type of data) or manually triggered (e.g. selecting a user interface option). The data formatting rule may be applied to other data and the results of the formatting reviewable by the user. Based on further edits/reviews, the data formatting rule may be updated. The data formatting rules may be stored for later use.

摘要翻译： 根据用户的编辑自动确定将数据从一个表单转换为另一个表单的数据格式化规则。 机器学习启发式应用于用户的编辑以确定可应用于数据的数据格式化规则。 例如，用户可以进行从数据添加/移除字符，连接数据，提取数据，重命名数据等的编辑。 可以响应于事件（例如在对相同类型的数据进行预定数量的编辑）或手动触发（例如，选择用户界面选项）之后，可以自动地触发机器学习启发式。 数据格式规则可以应用于其他数据以及用户可评估的格式的结果。 根据进一步的编辑/评论，可能会更新数据格式规则。 可以存储数据格式化规则供以后使用。
