  • Publication number: 20260330016
    Abstract: A prompt injection detection system intercepts queries to a generative artificial intelligence (AI) system and generates a response to the query with a first large language model (LLM). A second LLM is then instructed to determine a number of intents of the query, a true question the query is asking, whether the response is responsive to the true question the query is asking, and an explanation for the response being responsive or non-responsive to the true question. If the response is non-responsive to the true question of the query, the detection system blocks the query from being communicated/input to the generative AI system and flags the query as potentially being associated with a token smuggling prompt injection attack.

  • Publication number: 20260332609
    Abstract: An indication of a potential network threat and one or more network entries associated with the potential network threat are received. One or more example network exploit content associated with the potential network threat are identified. At least a portion of the one or more network entries and at least a portion of the identified one or more example network exploit content are analyzed using a large language model to determine a large language model output associated with whether the potential network threat is a false positive threat. The large language model output is utilized to provide a computer security analysis result.

  • Publication number: 20260332636
    Abstract: A security feed normalizer aggregates and normalizes threat intelligence data across security feeds and extracts threat descriptors of cybersecurity threats from the aggregated/normalized data. A first large language model (LLM) determines whether each threat descriptor is informative, i.e., comprises sufficient information for reproducing/generating network traffic of the corresponding cybersecurity threat. For informative threat descriptors, a second LLM generates network traffic for the corresponding cybersecurity threats. The generated network traffic is used for subsequent remediation of corresponding threats.

  • Publication number: 20260323621
    Abstract: This application provides a communication method and apparatus based on a configured grant configuration and an inter-frequency measurement configuration, to reduce a service transmission delay when an SPS transmission occasion collides and/or a CG transmission occasion collides with an MG. In this method, an access network device may send first configuration information and second configuration information to a terminal. The first configuration information is used to configure a first CG transmission occasion and a first time offset, and the second configuration information is used to configure a measurement occasion for inter-frequency measurement. The terminal and the access network device can perform transmission of uplink data on a second CG transmission occasion when the first CG transmission occasion overlaps the measurement occasion in time domain.

  • Publication number: 20260252464
    Abstract: A testing framework conducts a dialogue with a multi-modal foundation model to determine how to interact with an application via a user interaction emulator tool based on images captured from the UI of the application. Initially, the testing framework will capture an image of the application UI. The testing framework then prompts the foundation model to explain how to interact with the application to achieve a function of the application given the captured image. The testing framework derives commands from the model response for running the user interaction emulator tool and captures an image of the application UI after the interaction and again prompts the foundation model to determine whether the function was successfully performed or to explain a failure. The testing framework continues the dialogue with successive prompts for interaction with the application informed by the explanation of preceding failure.

  • Publication number: 20260247473
    Abstract: A physical downlink control channel (PDCCH) monitoring method is used to reduce power consumption of a terminal device. The method includes obtaining a first discontinuous reception (DRX) parameter used to configure a first DRX and a second DRX parameter used to configure a second DRX. A start time of a first cycle period of the first DRX is t1, a start time of a second cycle period of the second DRX is t2, and t1 is earlier than t2. When a time difference between t1 and t2 is less than a first threshold, PDCCH monitoring is initiated at a time t3, where t3 is no later than t2 and t3 is later than t1. This enables the terminal device to delay the start time of the first cycle period, reducing the time of PDCCH monitoring, thereby reducing power consumption of the terminal device.

  • Patent number: 12711186
    Abstract: A cybersecurity intelligence system maintains a current view of published cybersecurity issues by periodically crawling websites that publish information about cybersecurity issues, including first impression issues and updates to issues. The system aggregates unstructured descriptions for a same issue. For each published issue detected from crawling, the system prompts a foundation model to generate a structured representation that can be consumed. The structured representation includes key-value pairs corresponding to issue type and affected vendor product. Distilling and consolidating the issue descriptions into these informational components intelligently surfaces salient features of the information for addressing issues. After some quality assurance of the structured representations from the model, the structured representations are published for access by consumers.

  • Publication number: 20260238668
    Abstract: Techniques for inline exploit detection via loose condition forwarding and cloud analysis (e.g., cloud-based security analysis) are disclosed. In some embodiments, a system/process/computer program product for inline exploit detection via loose condition forwarding and cloud analysis includes monitoring network traffic of a session at a security platform; selecting a subset of the monitored network traffic associated with the session to send to a cloud-based security service for analysis based on a security policy, wherein the selected subset of the monitored network traffic is determined to be associated with suspicious session traffic that is selected using a prefilter condition (e.g., a prefilter signature, heuristics, machine learning implemented prefiltering condition, etc.) for an unknown exploit; and receiving, from the cloud-based security service, results of the analysis based on the security policy, and performing a responsive action based on the results of the analysis based on the security policy.

  • Publication number: 20260222442
    Abstract: A system facilitates multi-session, multi-aspect analysis of conversations between users and applications that leverage language models (“generative AI applications”). The system retrieves conversation logs for conversations carried out between users and a generative AI application(s) and sorts the conversation logs by conversation. The system analyzes the conversations in multiple aspects for various use cases: security, analytics, and organizational compliance. In the security analysis, the system analyzes the queries and responses of each conversation to determine if the conversation includes a multi-turn attack. For the analytics and organization compliance use cases, the system evaluates how end users are using the generative AI application(s) across conversations to provide customers with additional insights, such as the spread of subject matter areas for which employees are using the generative AI application(s).

  • Patent number: 12694110
    Abstract: A genetic algorithm is implemented to generate prompts that evade content filters of generative artificial intelligence (AI) systems. The genetic algorithm applies grammar operations to mutate candidate prompts, communicates the candidate prompts to generative AI systems, and selects candidate prompts that successfully evade content filters according to corresponding responses. A disambiguation model that corrects grammar in prompts is tested on the selected prompts to determine if grammar is properly corrected. Once tested, the disambiguation model is deployed in an ensemble with a classifier that outputs verdicts for prompts with grammar corrected by the disambiguation model.
