The processor is configured to load the program instructions from the memory, and by executing the program instructions, to process a three-dimensional image of a portion of a body of a subject in which multiple brachytherapy to identify clusters of voxels of the image corresponding to the seed groups, respectively, to compute respective estimated positions of the brachytherapy seeds based on respective dimensions of each of the clusters, and to store or communicate the estimated positions for use in computing an effective dose of the brachytherapy seeds. Other embodiments are also described.

Abstract: Methods and systems for penetration testing of a networked system involve assigning network nodes to disjoint classes based on current information about the compromisability of the network nodes. The classes distinguish between nodes not currently known to be compromisable, nodes that only recently have become known to be compromisable, e.g., by a first method of a attack, and nodes that have been known for a longer time to be compromisable. Nodes that only recently have become known to be compromisable can be re-targeted by the penetration testing system to determine whether such nodes can be compromised using multiple methods of attack and not just using the first method of attack.

Abstract: Apparatus and methods are described for use with electrophysiological signal detecting electrodes, and a transcranial magnetic stimulation device. A computer processor drives the transcranial stimulation device to apply one or more pulses of transcranial magnetic stimulation to a subject. Within a given time period of applying one of the one or more pulses of transcranial magnetic stimulation to the subject, the computer processor detects an electrophysiological signal of the subject, using the electrophysiological signal detecting electrodes. At least partially in response thereto, the computer processor predicts an outcome of treating the subject for a neuropsychiatric condition, using a given therapy, and generates an output on an output device in response to the predicted outcome. Other applications are also described.

Abstract: A method for executing a penetration testing campaign comprises performing a determination of conditional compromisability for one or more network nodes, including examining each given network node of the one or more network nodes to determine whether it can be compromised from a network node that is already determined to be compromisable and that can communicate with the given network node to the extent required for exploiting a vulnerability applicable to the given network node. Subsequently, for a selected target network node determined to be conditionally compromisable, a potential attacking node is selected from the already-determined-to-be-compromisable nodes and a check is made whether the selected potential attacking network node can communicate with the selected target network node to the extent required, thus leading to a determination that the selected target network node is not only conditionally compromisable but also actually compromisable by an attacker.

Abstract: Carrying out a penetration testing campaign in a networked system by a penetration testing system, for determining a way for an attacker to compromise the networked system, comprises determining that the attacker can obtain user credentials of a first user, determining that when using the user credentials the first user has access rights to a first network node of the networked system, determining that a second network node of the networked system is compromisable by the attacker during the penetration testing campaign, determining that the first network node was accessed from the second network node, and based on the foregoing, determining that the first network node is compromisable by the attacker during the penetration testing campaign, and determining the way for the attacker to compromise the networked system which includes a step of compromising the first network node using the user credentials of the first user.

Abstract: Methods and systems for penetration testing of a networked system by a penetration testing system. In some embodiments, both active and passive validation methods are used during a single penetration testing campaign in a single networked system. In other embodiments, a first penetration testing campaign uses only active validation and a second penetration campaign uses only passive validation, where both campaigns are performed by a single penetration testing system in a single networked system. Node-by-node determination of whether to use active or passive validation can be based on expected extent and/or likelihood of damage from actually compromising a network node using active validation.

Abstract: Methods and systems for penetration testing of a networked system by a penetration testing system (e.g. that is controlled by a user interface of a computing device) are disclosed herein. In one example, a penetration testing campaign is executed according to a manual and explicit selecting of one or more goals of an attacker of the penetration testing campaign. Alternatively or additionally, a penetration testing campaign is executed according to an automatic selecting of of one or more goals of the attacker (e.g. according to a type of attacker of the penetration testing campaign).

Abstract: Penetration testing campaigns generate remediation recommendations based at least in part on information about files stored in network nodes of the tested networked system. Information is obtained about files stored in a plurality of network nodes of the networked system, and based on the obtained information, a corresponding data-value score for each network node of the plurality of network nodes is determined according to a common data-value metric. The penetration testing campaign is executed, following which one or more remediation recommendations are selected based on the data-value scores corresponding to at least some of the plurality of network nodes.
