Secure computation environments are protected from bogus or rogue load modules, executables and other data elements through use of digital signatures, seals and certificates issued by a verifying authority. A verifying authority-which may be a trusted independent third party-tests the load modules or other executables to verify that their corresponding specifications are accurate and complete, and then digitally signs the load module or other executable based on tamper resistance work factor classification. Secure computation environments with different tamper resistance work factors use different verification digital signature authentication techniques (e.g., different signature algorithms and/or signature verification keys)-allowing one tamper resistance work factor environment to protect itself against load modules from another, different tamper resistance work factor environment. Several dissimilar digital signature algorithms may be used to reduce vulnerability from algorithm compromise, and subsets of multiple digital signatures may be used to reduce the scope of any specific compromise.

A system and method for detecting malware by modeling the behavior of malware and comparing a suspect executable with the model. The system and method extracts feature elements from malware-infected applications, groups the feature elements into feature sets, and develops rules describing a malicious probability relationship between the feature elements. Using malware-free and malware-infected applications as training data, the system and method heuristically trains the rules and creates a probability model for identifying malware. To detect malware, the system and method scans the suspect executable for feature sets and applies the results to the probability model to determine the probability that the suspect executable is malware-infected.

A system S is defined which is capable of simulating a computer (virtual computer, VC) for the purpose of software performance monitoring. The system is implemented as a set of software modules (SM) that can be exchanged to change the behavior of the VC. The VC is driven by a CPU emulator, and can run any operating system (virtual operating system, VOS) that is supported by the available SM's. The system is designed to log accesses to system resources and the nature of these accesses. The system is particularly useful for determining whether an executable or file contains an unknown virus, with a very low risk of false positives. Detected viruses include encrypted, polymorphic, metamorphic and other virus types.

In an inspection facility (e.g. at a gateway server, at a proxy server, at a firewall to a network, at an entrance to a local area network or even at the user's computer) connected to an anti-virus center for updates, a method for protecting a computer from suspicious objects (e.g. a file, an executable, a Web page, an email message, etc.), the method comprising the steps of: inspecting an object; upon determining the object as suspicious, holding the object in quarantine (e.g. preventing from the object to be forwarded to its destination) for a time period, thereby enabling the inspection facility to be updated during the time period by the anti-virus center; upon ending of the time period, re-inspecting the object, thereby inspecting the object by updated inspection tests; and upon determining the object as malicious by the re-inspection, blocking the object, otherwise forwarding the object toward its destination.

A method for mitigating false-positives as detected by antivirus software comprising accessing an operating system file that has been identified as malware; creating a signature for the operating system file; comparing the created signature to a signature database; and, if the created signature is not found in the signature database, defining the operating system file as malware. An operating system file, as used herein, is any file included as a part of the operating system binary executable file set, as well as any files added from third party vendors that integrate with or plug into the operating system.

An apparatus and method for self-healing of software may rely on a distribution object in a directory services of a network to provide data for controlling distribution of software and installation of files associated therewith. A software object may represent a software product, system, data structure, application, or the like, from a single byte, to a complex program. A directory services system is responsible for maintaining a data store of inter-related logical entities (directory services objects), including software objects and a distribution object containing all distribution information associated with certain distribution processes. Maintenance methods may be programmed into a directory services object or some other executable to verify the existence of files required for particular software. Verification may be completed in association with a launch request, by explicit request, or in an ongoing maintenance procedure. Maintenance may include executables and data to control, complete, and record integrity of distributed files as a distinct activity or as an ongoing, routine, periodic process of verification and appropriate re-installation of files, operating transparently to a user.

An executable file containing malicious software can be packed using a packer to make the software difficult to detect. The executable file is loaded into the computer's memory and executed as a process. A memory dump module analyzes the address space for the process and identifies an executable file image within it. The memory dump module creates a memory dump file on the computer's storage device containing the file image and modifies the file to make it resemble a normal executable file. A signature scanning module scans the memory dump file for signatures of malicious software. If a signature is found in the file, a reporting module sends the host file for the process and the memory dump file to a security server for analysis.

A polymorphic threat manager monitors an incoming email stream, and identifies incoming email messages to which executable files are attached. The polymorphic threat manager characterizes incoming executable files according to at least one metric. For example, the polymorphic threat manager can decompose an executable file into fragments, hash some or all of these, and use the hashes as characterization metrics. The polymorphic threat manager subsequently de-obfuscates executable files, and creates corresponding characterization metrics for the de-obfuscated images. The characterizations of executable files before and after de-obfuscation are compared, and if they differ sufficiently, the polymorphic threat manager determines that the file in question is polymorphic. The characterization metrics of such an executable file after de-obfuscation can be used as a signature for that file.

Security analysis and vulnerability testing results are “packaged” or “bound to” the actual software it describes. By linking the results to the software itself, downstream users of the software can access information about the software, make informed decisions about implementation of the software, and analyze the security risk across an entire system by accessing all (or most) of the reports associated with the executables running on the system and summarizing the risks identified in the reports.

An enhancement to e-mail user interfaces and message formats includes a dynamic preview window to view and retrieve attachments and summaries of e-mail messages directly in the e-mail list view or inbox view without opening an e-mail message. The efficient viewing mechanism further allows previews without cluttering the listing of the e-mails in the inbox by allowing the client to detect special preview instructions within an e-mail and run executables within the preview window. The enhancement is applicable to standalone e-mail clients (POP or IMAP based) and to web-based e-mail systems.

A collection agent monitors a mobile network for data samples containing executable code. The collection agent accepts executables and forwards them to a sample collection center for further analysis, reporting, or in some instances initiating one or more mitigating actions. Depending on the network protocol being monitored, the collection agent responds to connection attempts from nearby mobile devices.

A system and method for detecting malware on a mobile platform in a mobile network. The system and method verifies that an executable is malware-free by computing the checksum of the executable and comparing that checksum with a checksum obtained from a malware-free copy of the executable. The checksum is a sum of all 32-bit values in a code section and an import section of said executable, a byte sequence at an entry point in said executable, a size descriptor of an import table, a size descriptor of said import section, a cyclic redundancy check of said executable, or a combination thereof.

A software system is disclosed which facilitates the process of tracing the execution paths of a program, called the client. The tracing is performed without requiring modifications to the executable or source code files of the client. Trace data collected during the tracing operation is collected according to instructions in a trace options file. At run time, the tracing library attaches to the memory image of the client. The tracing library is configured to monitor execution of the client and to collect trace data, based on selections in the trace options file. Conditional tracing, through the use of triggers and actions taken in response to the triggers, allows the developer to control the tracing operation. The triggers can be conditional triggers in which the corresponding action is taken only if a conditional expression is satisfied. The system can trace multiple threads and multiple processes. The tracing system provides a remote mode and an online mode. In remote mode, the developer sends the trace control information (which can include triggers and corresponding actions) to a remote user site together with a small executable image called the agent that enables a remote customer, to generate a trace file that represents execution of the client application at the remote site. In online mode, the developer can generate trace options (including triggers and corresponding actions), run and trace the client, and display the trace results in near real-time on the display screen during execution of the client program.

A method, apparatus, client and server are directed at providing a simplified scheme to deliver email messages that include text message body, and/or MIME attachments from desktop computing devices to messaging (such as SMS) and wireless internet capable phones. A web form is provided for users to compose messages and/or adding MIME attachments from their PC. Also provided in the form are input fields for users to enter device numbers for recipients. Upon submitting the form, message body and MIME attachments are uploaded and stored on the server. An email WAP page that contains the message body and the links to all the MIME attachments is created dynamically and stored on the server. The server then queries a service database and looks up a domain routing table to build the email like messaging addresses for recipients. The server sends a notification message with an embedded link to the email like messaging addresses. The link, such as a URL, a script, an executable, a program, and the like, pointing to the email WAP page, can be invoked from mobile devices. When the link is invoked on the mobile device, it sends a request to the server for the email WAP page. Upon receiving the request from the mobile device, the server collects the information about the mobile device; queries a device database for formats, display and capabilities; locates and loads the email WAP page; converts the MIME attachments to the formats supported by the mobile device; formats the email WAP page for display on the mobile device; delivers the formatted email WAP page to the mobile device. The email WAP page can be viewed, downloaded, and played on the mobile device. The scheme of the present invention supports a device number based authentication. The scheme of the present invention can also be implemented to deliver email messages to multiple mobile devices. The scheme of the present invention can expand the PC to SMS capabilities by enabling text messaging with arbitrary message length.

A management method is disclosed for managing license information indicating an allowed amount of usage of a program executable on a peripheral device or a function provided by the peripheral device. The method includes the steps of acquiring, from the outside, license identification information for identifying license information, and license information indicating an amount of a change in right of usage of the program, managing license identification information corresponding to license information that has already been installed, determining whether license identification information corresponding to license information is included in license identification information managed in the management step, and performing operation such that if it is determined in the determination step that the license identification information corresponding to the license information is included in the license identification information managed in the management step, changing the value of the already installed right of usage of the program by an amount equal to a change in the right of usage of the program.

A system and method for providing a user interface with search query broadening is described. A query defining a search executable on potentially retrievable information is accepted. The query is parsed. A broadened query is provided. At least one of the broadened query and results of a search executed on the broadened query is presented.

A solid-state storage subsystem, such as a non-volatile memory card or drive, includes a main memory area that is accessible via standard memory access commands (such as ATA commands), and a restricted memory area that is accessible only via one or more non-standard commands. The restricted memory area stores information used to control access to, and/or use of, information stored in the main memory area. As one example, the restricted area may store one or more identifiers, such as a unique subsystem identifier, needed to decrypt an executable or data file stored in the main memory area. A host software component is configured to retrieve the information from the subsystem's restricted memory area, and to use the information to control access to and/or use of the information in the main memory area.
