An isolated environment is instantiated in response to receiving a request to execute a process. One or more events occurring within the isolated environment in which the process executes are identified. Whether the actual behavior of the process executing within the isolated environment deviates from an expected behavior of the execution of the process is determined. Only when it is determined that the process deviates from the expected behavior is behavior data, which describes the actual behavior of the process during execution, stored. A determination is then made as to whether the process is compromised by analyzing the behavior data that describes the actual behavior of the process.

Micro-virtual machine forensics and detection

The execution of a process within a virtual machine (VM) may be monitored, and when a trigger event occurs, additional monitoring is initiated, including storing behavior data describing the real-time events taking place inside the VM. This behavior data may then be compared to information about the expected behavior of that type of process in order to determine whether malware has compromised the VM. The trigger event may be analyzed in relation to a set of heuristics, and based on the analysis, a data collection process may be initiated wherein the data comprises information about events occurring in the first virtual machine.

Updating a central repository with information about malware resident upon a computer system. Upon detecting the malware executing in a virtual machine, a software module, without manual instruction, sends malware manifest data to a central repository over a network. The malware manifest data may comprise a copy of the malware and all versions, including temporary versions, of any files written to, updated by, or accessed by the malware. The central repository may receive, over a network from at least two computer systems, distinct sets of malware manifest data and may subsequently store the sets of malware manifest data.

Centralized storage and management of malware manifests
