Hardware embodiments are described in which the dynamically-generated code is permitted to executed but is monitored to ensure that the execution criteria are met. | 05-05-2022 |
| 20220138314 | AUTOMATED GENERATION OF A SANDBOX CONFIGURATION FOR MALWARE DETECTION - A method that automatically generates blacklists for a sandbox application. The method first obtains a set of disassembled operating system (OS) dynamic-link libraries (DLLs) and then identifies application programming interfaces (API) functions that have respective kernel interruptions. The identified API functions that have kernel instructions are saved to an interrupt list. Based on the interrupt list, a processor generates a blacklist that includes for each of the DLLs, the identified API functions in the interrupt list, all API functions that directly or indirectly invoke one of the identified API functions in the interrupt list via one or more nested API functions. The method outputs the blacklist to the sandbox application that operates on a sample file to emulate API functions of the sample file that match the blacklist. All other APIs not identified as being blacklisted, are then considered whitelisted and are allowed to run natively. | 05-05-2022 |
| 20220138316 | CHARACTERIZING SUSCEPTIBILITY OF A MACHINE-LEARNING MODEL TO FOLLOW SIGNAL DEGRADATION AND EVALUATING POSSIBLE MITIGATION STRATEGIES - The disclosed embodiments relate to a system that characterizes susceptibility of an inferential model to follow signal degradation. During operation, the system receives a set of time-series signals associated with sensors in a monitored system during normal fault-free operation. Next, the system trains the inferential model using the set of time-series signals. The system then characterizes susceptibility of the inferential model to follow signal degradation. During this process, the system adds degradation to a signal in the set of time-series signals to produce a degraded signal. Next, the system uses the inferential model to perform prognostic-surveillance operations on the set of time-series signals with the degraded signal. Finally, the system characterizes susceptibility of the inferential model to follow degradation in the signal based on results of the prognostic-surveillance operations. | 05-05-2022 |
| 20220138317 | Detecting and Protecting Against Cybersecurity Attacks Using Unprintable Tracking Characters - Aspects of the disclosure relate to detecting and protecting against cybersecurity attacks using unprintable tracking characters. A computing platform may receive a character-limited message sent to a user device. Subsequently, the computing platform may detect that the character-limited message sent to the user device includes suspicious content. Then, the computing platform may generate a modified character-limited message by inserting one or more special characters into the character-limited message and cause transmission of the modified character-limited message to the user device. Next, the computing platform may receive, from the user device, a spam report that includes the modified character-limited message. Then, the computing platform may identify a presence of the one or more special characters included in the modified character-limited message and adjust one or more filters based on the identification. | 05-05-2022 |
| 20220138333 | SYSTEM AND METHOD FOR ENABLING AND VERIFYING THE TRUSTWORTHINESS OF A HARDWARE SYSTEM - To determine whether an IoT system connected with a network environment (e.g., the internet) is compromised, a networked Trust as a Service (TaaS) server receives system data indicative of various characteristics of the IoT system, wherein the system data is harvested by a software agent installed on the IoT system. The TaaS server initially establishes a baseline characteristics profile for the IoT system, such that subsequently received system data from the software agent may be compared against the baseline characteristics profile to quickly identify discrepancies between the originally established baseline characteristics profile and current operating characteristics of the system. Such discrepancies may be caused by desirable software updates, in which case the discrepancies may be integrated into the baseline characteristics profile, or the discrepancies may result from the IoT system being undesirably compromised. | 05-05-2022 |
| 20220141237 | DETECTION OF ABNORMAL OR MALICIOUS ACTIVITY IN POINT-TO-POINT OR PACKET-SWITCHED NETWORKS - A method of detecting abnormal or malicious activity in a point-to-point or packet-switched data communication network includes tapping a link in the network to obtain a data stream transmitted from a node of the network in parallel with transmission of the data stream through the network. The tap is non-invasive because it does not interfere with the normal traversal of the data stream across the network. This is useful for certain applications, such as mission-critical systems, where it is desirable to monitor the network and inspect the data without adversely impacting or otherwise interfering with the normal operation of the system. The method further includes decoding a communication protocol encoded in the data stream to obtain payload data from the data stream, analyzing the payload data to detect abnormal or malicious activity, and notifying a host of the network of the detected abnormal or malicious activity in the payload data. | 05-05-2022 |

The interface system includes a gateway, a vulnerability scanner, switch, cameras, network access controller, and machine learning module. The interface system detects any unusual activity from a device on the network and can take autonomous decisions based on calculated scores to allow or block the unusual activity. | 05-05-2022 |
| 20220141240 | COMPUTER-IMPLEMENTED METHOD AND BLOCKCHAIN SYSTEM FOR DETECTING AN ATTACK ON A COMPUTER SYSTEM OR COMPUTER NETWORK - The disclosure relates to a computer-implemented method for detecting an attack on a computer system or computer network. The method includes: inserting an analysis code or module for the computer system or computer network as a smart contract into a blockchain having a plurality of blocks linked to one another; defining parameters for the analysis code; executing the analysis code based on the parameters; and inserting the analysis result into the blockchain. At least a portion of the parameters corresponds to the behavior of the computer system or computer network and includes a log file of the computer system or computer network. | 05-05-2022 |
| 20220141242 | SYSTEM AND METHOD FOR PROTECTION OF AN ICS NETWORK BY AN HMI SERVER THEREIN - A defense suite for an industrial control system (ICS) network is disclosed. The defense suite is installed and executed on a network server hosting the human-machine interface (HMI) function of the network, thereby gaining communication privileges of the HMI server to query and perform other operations with programmable logic controllers (PLCs) and other assets of the network. The defense suite further comprises a network protection engine (NWPE) that alerts a defense suite user of suspicious activity in the network. Normal behavior of the network is obtained by a learning engine, during a learning period. The learning engine can be reactivated after a configuration change in the network. The data suite also comprises an operating system protection engine (OSPE), for preventing removable devices from accessing the HMI server and a preventing execution of unauthorized executables. The OSPE is also trained for which programs are authorized through its own program discovery module. | 05-05-2022 |
