摘要： A message-hold decision maker system (102) used with an electronic mail processing system that processes electronic messages for a protected computer network improves the electronic mail processing system's performance by increasing the throughput performance of the system. The improvements are achieved by providing an electronic mail processing gateway (104) with additional logic that makes fast and intelligent decisions on whether to hold, block, allow, or sandbox electronic messages in view of potential threats such as viruses or URL-based threats. A message hold decision maker (106) uses current and stored information from a plurality of specialized classification engines (108, 110) to quickly make the decisions. In some examples, the message hold decision maker (106) will instruct an email gateway (104) to hold an electronic mail message while the classification engines (108, 110) perform further analysis.

摘要： Aspects of the disclosure relate to detecting and identifying malicious sites using machine learning. A computing platform may receive (505) a uniform resource locator (URL). The computing platform may parse and/or tokenize (510) the URL to reduce the URL into a plurality of components. The computing platform may identify (515) human-engineered features of the URL. The computing platform may compute a vector representation of the URL to identify (520) deep learned features of the URL. The computing platform may concatenate (525) the human-engineered features of the URL to the deep learned features of the URL, resulting in a concatenated vector representation. By inputting the concatenated vector representation of the URL to a URL classifier, the computing platform may compute (530) a phish classification score. In response to determining that the phish classification score exceeds a first phish classification threshold, the computing platform may cause a cybersecurity server to perform a first action (540, 545).

摘要： Systems and methods for analyzing applications on a mobile device for risk so as to maintain the privacy of the application user are provided. In the example method, the process receives a request from a mobile device. The request includes a cryptographic representation of application information for an application residing on a mobile device. The method includes comparing the cryptographic representation to an application information database that includes cryptographic representations of applications. The method also includes automatically remediating, e.g., quarantining and retiring, the application if the application matches an application that is a known risk in the database. Exemplary embodiments provide companies with controls to prevent specific applications—which have specific behaviors and are present on mobile devices being used by employees—from being used by employees, without the company having any visibility into what particular applications are being used by the employees on the mobile device.

摘要： Systems and methods for analyzing applications for risk are provided. In the example method, the applications reside on a mobile device that is configurable to access an enterprise system. The example method includes evaluating each of a plurality of applications variously for privacy, data leakage, and malicious behavior. The example method also includes calculating a risk score for each of the plurality of applications based on the evaluating; and automatically remediating (e.g., quarantining) the applications, of the plurality of applications, for which the risk score meets or exceeds a risk score threshold. The method may evaluate all of the applications residing on a mobile device. The method may include grouping application behaviors, for each of the applications, that indicate an increased risk into groups comprising various combinations of a privacy risk, a data leakage risk, an account takeover risk, a device takeover risk, and a malware risk.

摘要： Malicious message detection and processing systems and methods are provided herein. According to some embodiments, the messages are emails and the method for processing emails may be facilitated by way of an intermediary node which may be cloud-based. The intermediary node may be communicatively couplable with an email client and an email server. The intermediary node may execute a method that includes analyzing a link included in an email to determine if the link is associated with a potentially malicious resource, and replacing the link with an alternate link to a trusted resource if the link is associated with a potentially malicious resource.

摘要： Aspects of the disclosure relate to dynamic cybersecurity event detection and training functions. A computing platform may monitor (602) a plurality of user devices to detect (604) a cybersecurity training triggering event. In response to the detection, one or more cybersecurity training session prompts may be generated (612) and transmitted (614) to one or more user devices. User input providing a response to the cybersecurity training session prompt may be evaluated (618) for accuracy and scored (620) for the cybersecurity training session. In some examples, an overall cybersecurity score for a user may be maintained and modified based on the score for the cybersecurity training session. One or more modifications may be identified and executed based on the scores generated.

摘要： Aspects of the disclosure relate to processing external messages using a secure email relay. A computing platform may receive (305), from a message source server associated with a first domain, a first email message and a first set of authentication credentials. Based on validating (310) the first set of authentication credentials, the computing platform may inject (315), into the first email message, a DomainKeys Identified Mail (DKIM) signature of a second domain different from the first domain, which may produce a signed message that identifies itself as originating from the second domain. Based on scanning (320) and validating (325) content of the signed message, the computing platform may send (330) the signed message to a message recipient server, which may cause the message recipient server to validate the DKIM signature of the signed message and determine that the signed message passes Domain-based Message Authentication, Reporting and Conformance (DMARC) with respect to the second domain.
