In some embodiments, techniques for computer security comprise receiving an email message; determining a sender of the email message; determining whether the sender of the email message is trusted, wherein determining whether the sender of the email message is trusted includes determining whether the sender of the email message is associated with a whitelist; retrieving domain-related information by performing a DNS query on a domain associated with the sender; based at least in part on the domain-related information, determining whether the sender of the email message is verified; determining whether the sender is both trusted and verified; and when it is determined that the sender is both trusted and verified, treating the email message as trustworthy, wherein treating the email message as trustworthy includes bypassing a classifier.

In some embodiments, techniques for displaying a URL comprise receiving a URL; normalizing the URL, wherein normalizing the URL includes standardizing an encoding of a character contained in the URL; determining a first element of the URL, wherein the first element of the URL includes a domain; determining a second element of the URL; displaying the URL, wherein displaying the URL includes emphasizing the first element of the URL, and wherein emphasizing the first element of the URL includes displaying the first element of the URL using a first font attribute; and wherein displaying the URL includes displaying a first portion of the second element of the URL using a second font attribute and eliding a second portion of the second element of the URL; and responsive to an interaction with a user interface element, providing a view of the URL in its entirety.

A cryptography module for at least temporarily controlling an operation of at least one computing device. The cryptography module is designed to check at least one memory area of a memory unit capable of being accessed by the computing device, and to control the operation of the at least one computing device as a function of the check.

In some embodiments, techniques for computer security comprise receiving a message, receiving a user-originated request for an action, wherein the action is associated with the message, determining whether the message is trustworthy, and impairing performance of the action, if it is determined that the message is not trustworthy. In some embodiments, techniques for computer security comprise receiving a message, determining whether the message is trustworthy, rendering the message, if it is determined that the message is trustworthy, and rendering a restricted version of the message, if it is determined that the message is not trustworthy.

A computing device that includes at least one processor core for executing a first computer program, the computing device being designed to access a memory device, in particular in order to load the first computer program. The computing device is designed to transmit a first control command, which characterizes the first computer program and/or a memory area of the memory device associated with the first computer program, to at least one cryptography module. The cryptography module is designed in particular to check the computer program, or the memory area of the memory device associated with the first computer program, characterized by the first control command, and the computing device is designed to execute the first computer program.

A cryptography module for a computing device. The cryptography module is designed to check at least one memory area of a memory device which the computing device may access, as the result of which a result of the check is obtained, and to store the result at least temporarily.

Permissioned blockchains with off-chain storage establish integrity and no-later-than date-of-existence for documents, leveraging records containing hash values of documents. When a document's integrity or date is challenged, a new hash value is compared with a record in the blockchain. Proving date-of-existence (via hash value in a publication and/or SMS) for the block containing the record establishes no-later-than date-of-existence for the document. Permissioning monetizes operations, enforcing rules for submission rights and content, thereby precluding problematic material (privacy, obscenity, malicious logic, copyright violations) that threatens long-term viability. Compact records and off-chain storage in a document corral (with quarantine capability) preserve document confidentiality and ease storage burdens for distributed blockchain copies. Using multiple hash values for each document hardens against preimage attacks with quantum computing. Daisy chaining records establishes that relationships existed among documents at registration. Self-addressed blockchain registration (SABRe) permits documents to self-identify their blockchain record address (block ID, index).

A browser emulator is caused to emulate a client environment that is arbitrary values of types and versions of an OS, a browser, and a plugin. Further, the browser emulator monitors execution of a script or a plugin. A browser emulator manager then causes the browser emulator to patrol a predetermined Web site, and accumulates, in an analysis information database, results of access to the Web site in association with information on client environments emulated upon the access to the Web site. The browser emulator manager then refers to the accumulated results of access, and identifies a Web site that causes a difference between results of access according to a difference between client environments.

Systems and methods for providing secure motherboard replacement techniques are described. In one embodiment, an Information Handling System (IHS) may include computer-executable instructions to, during a bootstrap process, obtain a remodeled vendor tracking certificate from a replacement motherboard in which the remodeled vendor tracking certificate comprising inventory information associated with a previous motherboard, and determine that the vendor tracking certificate includes information indicating that the replacement motherboard has replaced a previous motherboard. When it is determined that the motherboard has replaced a previous motherboard, compare the inventory information with one or more devices installed with the replacement motherboard such that when the comparison fails, generate an alert message indicating that an inventory associated with the previous motherboard does not match a current inventory associated with the replacement motherboard, and when the comparison succeeds, allow the bootstrap process to complete.
