A discrete three-dimensional (3-D) processor comprises first and second dice. The first die comprises 3-D random-access memory (3D-RAM) arrays, whereas the second die comprises logic circuits and at least an off-die peripheral-circuit component of the 3D-RAM arrays. The first die does not comprise the off-die peripheral-circuit component of the 3D-RAM arrays.

Aspects of the disclosure are directed to a system for classifying software as malicious or benign based on predicting the effect the software has on the platform before the software is actually deployed. A system as described herein can operate in close to real-time to receive, isolate, and classify software as benign or malicious. Aspects of the disclosure provide for accurate classification of malicious programs or scripts even if ostensibly the program appears benign, and vice versa, based on the effect predicted by a machine learning model trained as described herein. The system can also be implemented to isolate and verify incoming scripts or software to the platform, to provide a predicted classification while not substantially impacting processing pipelines involving platform resources or the user experience with the platform in general.

In some examples, a system receives first measurements of data items used by a build server in building an executable program, the data items copied from a data repository to a storage partition that is separate from the data repository, and the storage partition to store the data items relating to building the executable program by the build server. The system determines, based on the first measurements and according to a policy specified for the storage partition, whether a corruption of the data items used by the build server in building the executable program has occurred.

Apparatus, systems, methods for measuring a side-channel is disclosed. The methods involve obtaining a first measurement of a magnetic field in a first range from the side-channel of the at least one electronic device; generating a version of the side-channel; obtaining a second measurement of the magnetic field in a second range from the version of the side-channel; and generating a composite measurement of the magnetic field from the side-channel of the at least one electronic device based on the first measurement and the second measurement. The first range includes a minimum threshold and at least a portion of the second range is less than the minimum threshold of the first range.

Disclosed herein are systems and method for blocking malicious script execution. In one exemplary aspect, the method may comprise detecting an execution of a script that creates or modifies a file on a computing device and recording a first report comprising a list of operations involved in the execution of the script, an identifier of the script, and an identifier of the file. The method may comprise determining that the file includes malicious code using a malware scanner and recording a second report comprising an indication that the file includes malicious code and an identifier of the file. In response to determining that identifier of the file is present in both the first report and the second report, the method may comprise generating and storing a first rule that prevents complete execution of any script that shares at least one operation in the list of operations with the script.

Disclosed herein are systems and method for preventing zero-day attacks. A method may include receiving a first report including information about an execution of a first script of an application that modifies a file on a first computing device, and receiving a second report including an indication that the file includes malicious code. In response to determining that an identifier of the file is present in both the first report and the second report, the method may include generating and transmitting, to the first computing device, a first rule that prevents execution of any script that shares at least one operation of the first script. The method may include, in response to determining that a vulnerability detected by the first rule is not present in a vulnerability database, generating an entry in the vulnerability database for the vulnerability as a zero-day vulnerability and transmitting an alert to the application developer.

Provided are a cyber threat information processing apparatus, a method thereof, and a storage medium storing a cyber threat information processing program. It is possible to provide a cybersecurity threat information processing method including disassembling an input executable file to obtain disassembled code, and reconstructing the disassembled code to obtain reconstructed disassembled code, into a hash function, and converting the hash function into N-gram data (N being a natural number), and performing ensemble machine learning on block-unit code of the converted N-gram data to profile the block-unit code by an identifier of an attack technique performed by the block-unit code and an identifier of an attacker generating the block-unit code. It is possible to detect and address a variant of malware, and identify malware, an attack technique, an attacker, and an attack prediction method within a significantly short time even for a variant of malware.

In one embodiment, a system for managing a virtualization environment includes a set of host machines, each of which includes a hypervisor, virtual machines, and a virtual machine controller, and a data migration system configured to identify one or more existing storage items stored at one or more existing File Server Virtual Machines (FSVMs) of an existing virtualized file server (VFS). For each of the existing storage items, the data migration system is configured to identify a new FSVMs of a new VFS based on the existing FSVM, send a representation of the storage item from the existing FSVM to the new FSVM, such that representations of storage items are sent between different pairs of FSVMs in parallel, and store a new storage item at the new FSVM, such that the new storage item is based on the representation of the existing storage item received by the new FSVM.

A DNS server receives from a receiving email system, a DNS query for an email domain stored at the DNS server, the DNS query including identifying information of a sender of an email. The DNS server extracts the identifying information of the email sender from the DNS query and identifies one of a plurality of delivering organizations from the information. The DNS server determines whether the identified delivering organization is authorized to deliver email on behalf of the email domain. In response to determining that the identified delivering organization is authorized to deliver email on behalf of the email domain, the DNS server generates a target validation record based on the identity of the authorized delivering organization and the email domain, the target validation record including one or more rules indicating to the receiving email system whether the delivering organization is an authorized sender of email for the email domain.
