  • Publication number: 20240054231
    Abstract: To decrease development revision cycle time and reduce deployment and execution errors when porting software from a public cloud to a specialized cloud, the software is analyzed for certain characteristics. Analysis may check for non-permitted items, required items, fragile code, morph code, or deny list expressions, for example. The particular items, codes, expressions, or other characteristics targeted by analysis derive from gapping constraints that distinguish the specialized cloud from public clouds, such as an air-gap constraint, a geolocation constraint, or a government security constraint. Software cloud compatibility analyses may be added, removed, or updated using a modular framework architecture, using declarative analysis module declarations, or both. False positive analysis results may be filtered out. Analysis results may include suggestions.

  • Publication number: 20240017254
    Abstract: Described herein is a system and method for determining the presence and/or amount of a target in a sample. In some embodiments, a microfluidic device, such as a strip having a microfluidic network thereon, is inserted into an instrument to perform an assay therein. The strip may be configured to receive the sample from a porous member via capillary action, with minimal or no compression of the porous member. The instrument may include a gas bladder actuation assembly, actuated by an eccentric cam, to compress and decompress a gas bladder on the microfluidic device, thereby enabling fluid movement thereon. The instrument may further comprise a magnet disposed in a fixed location, so as to capture any complexes formed between the target and magnetic particles disposed within the microfluidic device. The magnet may be aligned with an optical detection assembly configured to detect the target captured with the magnetic particles.

  • Patent number: 11503070
    Abstract: The present disclosure generally relates to web page analysis, and more particularly to a classification system for web pages. The classification system may classify a web page as malicious based upon one or more signatures generated for the web page. For example, the classification system may compare one or more signatures generated for a first web page to one or more signatures generated for a second web page, where the first web page and the second web page are the same web page at different times or different web pages. Based upon a similarity of the signatures, the classification system may output whether the first web page is malicious. For another example, the classification system may include a classification model that is trained based upon one or more signatures for one or more classified web pages. The classification model may output whether the web page is malicious.

  • Patent number: 11343269
    Abstract: An inventory of Internet-facing assets related to a username within a social media site is generated using network data gathered from network data sources. Using data sources of known threats, such as malware, phishing attempts, scam pages, blacklisted sites, and so on, a network analytic system generates analytical information about components that are owned, managed, and/or controlled by a target entity. A measure of identity threat is generated based on a classification model using the analytical information.
