  • Publication number: 20250202919
    Abstract: A method for detecting and preventing bot activity in a protected environment by leveraging API behavior analysis is disclosed. The method includes identifying target APIs vulnerable to bot attacks through the analysis of parameters such as user credentials and session tokens. It determines the importance of target APIs based on call volume and context, generating correlation keys from headers, cookies, or payloads to track API flows. The method identifies mandatory and probable pre-APIs using historical patterns, assigns risk scores based on criticality, and validates API request sequences in real-time by analyzing integrity and sequence likelihood. Caching mechanisms store data related to APIs, correlation keys, and invocation paths for real-time lookups. Incoming requests are assessed for missing pre-APIs or sequence deviations, with substitute APIs validated against thresholds. Requests flagged as bot traffic are blocked, ensuring secure API workflows and mitigating automated threats effectively.

  • Patent number: 12321753
    Abstract: Disclosed methods include initiating a system basic I/O system (BIOS) and, responsive to detecting an empty drive, accessing evaluating local BIOS telemetry data associated with installation of a new drive. Upon determining that the BIOS telemetry data a specified criteria, a long disk self-test (DST) and a short DST, may be performed. If the DSTs generate no hardware errors, hard drive service data including, for example, call log and service tag history associated with the information handling system, may be retrieved from a cloud backend to authorize an OS installation. Upon approving an OS installation, a service operating system (SOS) image may be retrieved from an OEM backend and a special key operable to cause a startup service of the SOS to boot to an OS installation flow may be accessed from a firmware volume in SPI flash to enable the SOS to initiate an OS installation flow.

  • Patent number: 12321755
    Abstract: An operating system (OS) software service detects an accessibility change event and takes a snapshot of the accessibility settings before sending and receiving memory-mapped input/output (MMIO) commands with an embedded controller (EC) to establish trust using existing security hardening methods. The software service may send an MMIO command that includes the profile as a payload to the EC. The EC extracts the profile payload and saves it to an NVRAM variable before signaling a basic input/output system (BIOS) during early boot of an available accessibility profile. The EC publishes an accessibility profile presence to a BIOS pre-EFI initialization (PEI) layer, which sends a command to the EC to return the response.

  • Publication number: 20250111044
    Abstract: Disclosed methods and systems consume vulnerability information from one or more security services associated with an information handling system. Based at least in part on the vulnerability information, a vulnerability status of the information handling system and/or an application running on the information handling system is determined. A vulnerability mitigation policy corresponding to the vulnerability status is determined and the vulnerability mitigation policy is then enforced while the vulnerability status persists. Enforcing the vulnerability mitigation policy may include restricting functionality of the information handling system, restricting execution of the application, or both.

  • Publication number: 20250045384
    Abstract: Disclosed systems and methods employ an embedded controller (EC) to monitor password activity and, responsive to detecting the password activity satisfying a criterion associated with a security policy managed by the EC, take action to restrict access to and/or operation of the platform in accordance with the security policy. The monitoring of password activity may include monitoring unsuccessful password change and password unlock attempts in both a preboot and runtime operating environment and within any of various available boot paths including, as examples, an operating system (OS) boot path, a network OS boot path, and a service OS (SOS) boot path. The OS boot source may be one of various telemetry events reported to a cloud-based risk assessment engine. Monitoring password change and password unlock attempts may include monitoring how many unsuccessful password change and unlock attempts have occurred since a most recent successful password change or password unlock attempt.

  • Patent number: 12086260
    Abstract: Systems and methods are provided to perform BIOS recovery for a first information handling system that is in a no-boot state, i.e., in which the original equipment manufacturer (OEM) boot block (OBB) on the first information handling system is corrupted or damaged and thus does not properly execute. OBB BIOS recovery may be achieved using logic executing on a second and different information handling system that is wirelessly communicating with initial boot block (IBB) BIOS firmware that is executing on the first information handling system. The logic executing on the second information handling system may select and download (e.g., from a remote server) a correct uncorrupted and undamaged copy of the BIOS recovery firmware version for the first information handling system, and then wirelessly transfer the downloaded new copy of the OBB BIOS firmware version to the first information handling system via an established secure wireless connection.

  • Patent number: 11928214
    Abstract: SPI firmware updates can be performed at runtime. A secure SPI flash access domain can be created during pre-boot and used at runtime to deliver and write a SPI firmware update to SPI flash. The secure SPI flash access domain can ensure that only a trusted component running on a trusted CPU core can access a SPI memory layout used to deploy the SPI firmware update to the SPI flash. Once the SPI firmware update is written to the SPI flash, a reboot can be triggered so that the updated SPI firmware is loaded to perform the boot process.

  • Publication number: 20240031316
    Abstract: Disclosed are systems, methods, and non-transitory computer-readable storage media for managing email attachments in an online content management system. In some implementations, a messaging client can receive input attaching a content item to an electronic message in a message thread. In response to the input, the messaging client can store the content item in a file system managed by an online content management system, generate a link to the content item, and insert the link in the electronic message. The content item can be shared with the recipients of the electronic message such that the content item can be synchronized across recipient devices by the online content management system. The messaging client on each recipient device and/or the sender's device can present representations of the attachments associated with the message thread in a centralized location on a GUI of the messaging client.
