An individualized time-to-live (TTL) is determined for a reputation score of a computer file. The TTL is determined based on the reputation score and the confidence in the reputation score. The confidence can be determined based on attributes such as the reputation score, an age of the file, and a prevalence of the file. The reputation score is used to determine whether the file is malicious during a validity period defined by the TTL, and discarded thereafter.

Installer package information is presented to a user in response to an attempted installation of an application on an endpoint. The attempted installation is detected and the installer package is identified to an information server. The installer package may be identified using a hash key or other unique identifier. In response, the information server provides to the endpoint information associated with the identified installer package based on information received from a plurality of other endpoints. The endpoint may also provide installation and application information related to the installer package to the information server. In one embodiment, when the information server obtains more than the threshold amount of information for an installer package, the information server may analyze the information and provide the analysis to requesting endpoints. The analysis may include the risk or performance impact of the installer package, or the category or functionality of the application.

Techniques for securely performing reputation based analysis using virtualization are disclosed. In one particular exemplary embodiment, the techniques may be realized as a computer implemented method for performing reputation based analysis comprising detecting a specified activity associated with a virtual client, determining a reputation associated with the specified activity, and performing an action associated with the determined reputation.

A computer-implemented method for authenticating requests from a client running trialware through a proof of work protocol is described. A request received from a client running trialware is analyzed. A cryptographic puzzle is generated if an authentication token is not included with the request. The cryptographic puzzle is transmitted to the client. A solution to the cryptographic puzzle received from the client is analyzed. A response to the request is generated if the received solution to the puzzle is validated.

A method and system for protecting users from accidentally disclosing personal information in an insecure environment. In one embodiment, the method includes monitoring I/O device input data associated with a guest operating system on a virtualization platform. The guest operating system has less privilege than a privileged operating system on the virtualization platform. The method further includes determining whether the I/O device input data corresponds to personal information of a user, and delaying or blocking the transfer of the I/O device input data to the guest operating system if the I/O device input data corresponds to the personal information of the user.

Detecting anomalous network activity through transformation of a terrain is disclosed. A set of network properties is mapped into a multidimensional terrain. The terrain is transformed into an observation domain in which data events of interest are amplified relative to other data comprising the terrain. The transformed terrain is evaluated for anomalous network activity.
