Abstract: Cyber security testing with automated system message processing for input and result determination is disclosed, including issuing, by a test tool, a call to an authorized service; identifying, by the test tool, one or more system-level error messages generated after issuing the call; determining, by the test tool based on at least one first system-level error message, a missing input for the call to the authorized service; and reissuing, by the test tool, the call to the authorized service with the missing input.

Abstract: An anonymous leaderboard for a monitored computing environments is provided. In response to an entity registering with the monitored computing environment (MCE), an encrypted identity and a dynamic non-fungible token (NFT) are generated for the registered entity, where the dynamic NFT has an associated blockchain technology data structure. The blockchain technology data structure is associated with the encrypted identity. A progress element notification is received from the MCE in response to the entity satisfying criteria for a predefined progress element associated with the MCE. In response, a static NFT, corresponding to the predefined progress element, is generated and stored as a block in the blockchain technology data structure. An entry in an anonymous leaderboard output is generated based on the blockchain technology data structure, where the entry identifies the entity by the encrypted identity.

Abstract: A computer-implemented method for generating penetration tests automatically includes parsing an existing system test case, and identifying a particular program call in the system test case. The particular program call can require a particular data access authorization. The method further includes, in response to the system test case including the particular program call, generating a penetration test using a predetermined attack vector. The method further includes executing the penetration test and detecting an unauthorized access being performed during the penetration test. Further, the method includes responsively, sending a notification that identifies the particular program call.

Abstract: A method includes receiving test objective data indicates an objective to be achieved during a cybersecurity test of a target system. An attack tree is generated by processing the test objective data into attack tree data including a plurality of data parameter sets and links between data parameter sets. Complexity of the attack tree is analyzed based on the test objective data using a combinatorics model. The attack tree is reduced to achieve the objective of the cybersecurity test based on the analyzed complexity of the attack tree.

Abstract: Methods, systems and computer program products for providing a customized display of social media content that is automatically filtered based on emotional content are provided. Aspects include receiving a plurality of social media posts that have been published for display by a social media service. Aspects also include receiving an emotional profile including social media post filtering preferences that are based on emotional content of social media posts. In response to performing an emotional content analysis of each of the plurality of social media posts, aspects include identifying a set of emotionally acceptable social media posts and a set of emotionally unacceptable social media. Aspects also include causing the set of emotionally acceptable social media posts to be displayed in a primary news feed window of the social media service in association with an account of the user of the social media service.

Abstract: Techniques for system kernel error identification and reporting for a computer system are described herein. An aspect includes detecting an error during the execution of a program. Another aspect includes determining whether the error is a system kernel error in the program. Another aspect includes, based on determining that the error is a system kernel error, generating a report regarding the determined system kernel error.

Abstract: A system includes a memory system and a processing system operably coupled to the memory system. The memory system includes a plurality of address spaces. The processing system is configured to perform operations including creating a data space from within a primary address space and a primary address space number access list entry referencing the data space. An unauthorized caller routine in a home address space configured to issue a service request including an address space-switching program call from the home address space to a program call target routine in the primary address space. The address space-switching program call references the primary address space number access list entry in the primary address space. A vulnerability identifier associated with the program call target routine is created and logged based on one or more conditions indicative of a cross-memory integrity violation detected responsive to the service request.

Abstract: A system includes a memory system and a processing system operably coupled to the memory system. The processing system is configured to perform operations including setting a target register to point to a first protected storage location of the memory system resulting in a protection exception upon access, calling an authorized service, and confirming that the authorized service uses the target register based on detecting the protection exception. The target register is adjusted to point to a parameter list including one or more known values and a pointer to a second protected storage location resulting in the protection exception upon access to confirm use of a value of the parameter list responsive to calling the authorized service. Parameter list testing and target register testing is repeated for locations in the parameter list and target registers to construct a testing profile for vulnerability testing of the authorized service.
