Abstract:
Among other things, this document describes a computer-implemented security method such as for authenticated selection of security countermeasures and for reliable identification of computing devices. The method can include receiving, by a computing system, a request from a computing device for an electronic resource. The computing system can identify a security token received from the device that made the request. Based on the security token, particular security countermeasures can be selected that are to be applied to the electronic resource to be served in response to the request. The countermeasures can be operable to interfere with an ability of malware to interact with the served electronic resource when the served electronic resource is on the computing device. Portions of the electronic resource that are to be executed on the computing device can be re-coded using the selected particular security countermeasures.
Abstract:
Methods and apparatus are described for detecting browser extensions. Specific implementations relate to configurable security policies and automated actions performed in response to the detection of browser extensions.
Abstract:
In an embodiment, a computer system is configured to receive, from a client computer, a request with one or more values; determine, based on the one or more values, whether the request is from a platform-specific application compiled for a first computer platform; determine, based on the one or more values, whether the platform-specific application is being executed within an emulator being executed by a second computer platform, wherein the second computer platform is different than the first computer platform.
Abstract:
In an embodiment, a data processing system comprises one or more processors; script analysis logic coupled to the one or more processors and configured to obtain a particular electronic document from a server computer; script injection logic coupled to the one or more processors and configured to insert a set of script code into source code of the electronic document to result in producing a modified electronic document prior to providing the modified electronic document to a client computer; wherein the script code is configured to improve resistance of the client computer to attacks by running upon loading in the client computer and to cause transforming, when running in the client computer, one or more values of one or more elements of the source code of the electronic document into obfuscated values of the one or more elements. As a result, the system and method herein improve resistance of the client computer to attacks.
Abstract:
A computer-implemented method includes receiving, at a computer security server system located between the Internet and a client computing device that makes requests over the Internet, a request for content directed to a particular content server system; forwarding the received request, with the computer security server system, to the particular content server system; receiving code from the particular server system in response to the request; applying a security countermeasure to the received code to created transformed code; providing the transformed code to the client computing device; receiving a communication from the client computing device; and determining that software on the client computing device has attempted to interact with the received code rather than the transformed code.
Abstract:
An app interacts with a human user of a user device that is executing the app while the app is also interacting over a network connection to an API server by making API calls to the API server and using the responses. An intermediary is provided between the API server and user devices/clients that modifies application programming interface interactions to disrupt automated attacks on those client-server interactions, at least as to those API interfaces that are known to be human-interaction API interfaces. The human-interaction API calls are disassociated to thwart automated attacks using those API calls. The disassociation can be provided through the use of user interface builder packages to provide instructions to the app as to performing human user interaction. Disassociating can be done by separating labels from their meaning, such as by assigning random values to the labels or other methods of obfuscating relations and structure.

Abstract:
A computer-implemented security method includes receiving, at a server sub-system, reports from a plurality of clients that were served content served by a web server system, the different versions of content varying from each other by polymorphic transformation that inserts varying content at common locations in the content; determining, with the server sub-system, an effectiveness level of security countermeasures applied to the content, using the received reports; selecting an updated security countermeasure package determined to address malware identified using data from the reports; and providing to the web server system information causing the web server system to switch to the updated security countermeasure package.
Abstract:
This document generally relates to systems, method, and other techniques for identifying and interfering with the operation of computer malware, as a mechanism for improving system security. Some implementations include a computer-implemented method by which a computer security server system performs actions including receiving a request for content directed to a particular content server system; forwarding the request to the particular content server system; receiving executable code from the particular content server system; inserting executable injection code into at least one file of the executable code; applying a security countermeasure to the combined executable code and executable injection code to create transformed code; and providing the transformed code to a client computing device.
