Abstract: An apparatus for managing data in a network is provided. The apparatus includes a memory, and a processor configured to identify a first leader device and a second leader device in a swarm comprising a plurality of devices based device parameters, receive a request for downloading data, download, as the first leader device, the data from a content device in response to the request, store the downloaded data to the memory, transmit the data to the second leader device, and divide the swarm into a first sub swarm comprising the first leader device and a second sub swarm comprising the second leader device.

Abstract: An embodiment of the present invention is directed to systems and methods for securing contactless cards from unauthorized payments, including card cloning attacks. An embodiment of the present invention provides a password at the time of usage of the card to decrypt the data contained in the card at the time when the user is initiating a transaction. In this exemplary illustration, card data may be encrypted at rest, and decrypted at the time of use. Other variations may include a switchable antenna that is disabled at rest and enabled during a transaction.

Abstract: Traffic into and out of an organization-level network is monitored. A request for an encryption key from ransomware infecting a computer in the organization-level network to a remote command and control server is detected. A simulated reply to the ransomware is generated. A known encryption key for which the corresponding decryption key is also known is substituted for the encryption key supplied by the C&C server. The simulated reply containing the substituted known key is then supplied to the ransomware, such that the ransomware uses the known encryption key to encrypt files accessible from the computing device, and requests payment in order to provide a decryption key. Instead of paying the ransom, the encrypted files are decrypted using the known decryption key corresponding to the known encryption key which was provided to the ransomware.

Abstract: A display apparatus having a communicator configured to communicate with an external device; a display; and a controller configured to receive schedule information about reproduction of a plurality of pieces of content from the external device, determine whether second content to be reproduced following first content is completely downloadable until a reproducing completion time of the first content based on the received schedule information, download the second content while reproducing the first content if it is determined that the second content is completely downloadable, and start downloading the second content instead of reproducing first content if it is determined that the second content is not completely downloadable.
