Abstract: Techniques are described for detecting attacks that employ a display name in an email to impersonate an email sender. A computing infrastructure hosting an email security platform may determine a similarity between the display name and an email address from which the email was received. The email security platform may determine the similarity by comparing a string associated with the display name and a string associated with the sender address. The email security platform may generate a similarity value based on a result of the display name being compared with the sender address. The email security platform may determine that the email includes the display name impersonating a name of the sender, based on the similarity value meeting or exceeding a threshold value indicative of impersonation. The email security platform may delete or quarantine the email from an inbox associated with a user account.

Abstract: In one example embodiment, a server obtains network flow metadata of a network flow of a host in a network. The server identifies one or more attributes of the network flow metadata. For each host group of a plurality of host groups, the server determines whether the one or more attributes of the network flow metadata satisfy one or more criteria for the host group. For each host group for which it is determined that the one or more attributes of the network flow metadata satisfy the one or more criteria, the server classifies the host as belonging to the host group.

Abstract: A method is disclosed of tracing a path to be taken by a mobile terminal receiving electromagnetic waves transmitted by transmitter stations, the path being traced by an operating platform, which method comprises a learning phase comprising a taking of the path during which, exclusively on the path, a periodic routine learning recording of successive groups of samples is made in a route memory, a sample comprising at least one value of each of the frequencies received at each of the periodic recordings, and a receive level associated with that frequency, and a comparison of the received levels between a group of pn samples recorded during a sampling of rank n and one recorded preceding group of rank lower than n, a comparison criterion discriminating between remarkable groups and ordinary groups.

Abstract: The invention concerns an installation with piezoelectric element for transmitting or receiving ultrasonic waves in a structure, the electrodes (8) of said element (7) being connected, as the case may be, to a powering circuit producing energizing electric signals designed to enable it to transmit ultrasonic signals in said structure (6), or to a circuit receiving electric signals transmitted by said element under an energizing ultrasound received by it from said structure, said piezoelectric element (7) being integrated in the structure. The powering or receiving circuits of said piezoelectric elements (7) consist each of a magnetic induction loop (9) likewise comprised in the structure (6) and capable of receiving from an external circuit (10, 11) or respectively transmitting thereto, electromagnetic signals.

Abstract: The invention relates to a method for monitoring a person carrying a cellular telephone through a communication network wherein: An expected path for the monitored person is determined by identifying a sequence of successive places or checkpoints, and A real path followed by the monitored person is detected and compared with the expected path, both in space and in sequence, so that An alert is sent to at least one individual, called alertee, through the communication network when the real path differs from the expected path in place, sequence or in both place and sequence. The invention also relates to a cellular telephone and a server implementing such method.
