    Abstract: Detecting malware includes monitoring an event stream for an executable program, where the event stream includes a plurality of events such as API call events. A first plurality of hash values is determined for the event stream. In response to an occurrence of a trigger event in the event stream, the first plurality of hash values for the event stream can be compared with a second plurality of hash values that represents an event stream for a known malware executable. A determination can be made if a behavior represented by the first plurality of hash values is a permitted behavior based on the comparison.

    Abstract: Detecting a Domain Name Service (DNS) hijacking includes resolving names in a hijack target group list to their respective Internet Protocol (IP) addresses. In response to determining that two names in the hijack target group list resolved to a common IP address, a determination is made whether a legitimate reason exists for the two names in the hijack target group list to resolve to the common IP address. In response to determining that a legitimate reason does not exist for the two names in the hijack target group list to resolve to a common IP address, a DNS hijacking is indicated.

    Abstract: Systems and method identify potentially mislabeled file samples. A graph is created from a plurality of sample files. The graph includes nodes associated with the sample files and behavior nodes associated with behavior signatures. Phantom nodes are created in the graph for those sample files having a known label. During a label propagation operation, a node receives data indicating a label distribution of a neighbor node in the graph. In response to determining that the current label for the node is known, a neighborhood opinion is determined for the associated phantom node, based at least in part on the label distribution of the neighboring nodes. After the label propagation operation has completed, differences between the neighborhood opinion and the current label distribution for nodes are determined. If the difference exceeds a threshold, then the current label may be incorrect.

    Abstract: Methods, systems and devices for securing a bank account against an unauthorized access from a portable electronic device include or include using an auxiliary security device and a portable electronic device. The portable electronic device is adapted for controlling the bank account via the Internet. The auxiliary security device and the portable electronic device communicate via a Bluetooth protocol. Secure access to the bank account with the portable electronic device is based on a combination of information that is indicative of a key that is stored in the portable electronic device and data that is indicative of the key stored in the auxiliary security device that has been transmitted to the portable electronic device.

    Abstract: Systems and methods create virtual disks for access by a virtual machine. The virtual disk can be created from marked folders such that files and folders containing sensitive data or data not necessary for the purpose of a virtual machine using the virtual disk can be omitted from the virtual disk.
