  • Publication number: 20240106633
    Abstract: Embodiments of this specification provide account opening methods, systems, and apparatuses. An example method is performed by a terminal device that includes a trusted execution environment (TEE) and an encryption hardware-based secure element. When it is detected that a current user initiates an account opening request, the terminal device obtains a user public key of the current user in the TEE, and signs a user public key by using a predetermined manufacturer private key, to obtain a user certificate; signs, in the secure element by using a user private key corresponding to the user public key, opening information; generates an opening request in the TEE based on at least the user certificate and signed opening information; and, in the TEE, generates an opening request packet based on the opening request, and sends the opening request packet to a server that opens an account based on the opening request packet.

  • Patent number: 11677764
    Abstract: The automatic generation of malware family signatures is disclosed. A set of metadata associated with a plurality of samples is received. The samples are clustered. For members of a first cluster, a set of similarities shared among at least a portion of the members of the first cluster is determined. The similarities are evaluated for suitability as a malware family signature. Suitability is evaluated based on how well the similarities uniquely identify the members of the first cluster. In the event the similarities are determined to be suitable as a malware family signature, a signature is generated.

  • Patent number: 11444978
    Abstract: Disclosed is classifying a URL and a page accessed via the URL as phishing or not. URL embedder extracts characters in a predetermined set from the URL to produce a character string trained using ground truth classification of the URL, producing a URL embedding. HTML parser accesses content at the URL and extracts HTML tokens from the page. Further, HTML encoder, trained on HTML tokens extracted from pages at example URLs, each example URL accompanied by a ground truth image captured from the page accessed via the example URL, produces an HTML encoding of the extracted tokens. Also, phishing classifier layers, trained on the URL embedding and the HTML encoding of example URLs, processes a concatenated input of the URL embedding and the HTML encoding to produce a score of a phishing risk.
