Abstract: Systems and methods for detection of suspicious phishing webpages are provided. According to one embodiment, a client device captures an image pertaining to a webpage attempted to be accessed via the client device and generates a fingerprint of the webpage based on application of a hash function to the captured image. For each phishing fingerprint within a phishing fingerprint database containing fingerprints associated with known phishing webpages, the client device determines a similarity measure between the generated fingerprint and the phishing fingerprint by comparing the generated fingerprint with the phishing fingerprint such that when the similarity measure meets a threshold, the client device identifies the webpage as potentially being a phishing webpage. The phishing fingerprint database periodically receives an update containing new fingerprints from an online security service.

Abstract: Systems and methods are described for detecting compromised web pages and domains by analyzing of elements of hypertext markup language (HTML) files of a domain. In one embodiment, a security service receives a request including a potentially malicious uniform resource locator (URL) and retrieves a first HTML file to which the potentially malicious URL points and a second HTML file to which a host URL corresponding to the potentially malicious URL points. The security service determines whether the potentially malicious URL is a malicious URL by comparing features of the first HTML file to corresponding features of the second HTML file and when a similarity value resulting from the comparing is less than a threshold, then the security service concludes that the first HTML file was created by a malicious actor and responds to the request with an indication that the potentially malicious URL is a malicious URL.

Abstract: In one embodiment, a method for scheduling tasks comprises, at a task scheduler of a processing node of a plurality of processing nodes: retrieving a first task descriptor from a local memory of the task scheduler, the task descriptor corresponding to a task scheduled for execution at the current time and comprising at least a task execution time, a frequency for performing the task, and a task identifier; determining whether the task descriptor is assigned to the task scheduler for execution; if it is determined that the task descriptor is assigned to the task scheduler for execution: executing the task; updating the task execution time based on the current task execution time and the frequency for performing the task; and re-queuing the task descriptor in the local memory.

Abstract: A unified distributed real-time quota limitation system limits use of shared networked resources in distributed networked environment (DNE). A dispatch center determines an amount of shared resources available to client devices in the DNE. The dispatch center determines an amount of the shared resources to allocate for use by the clients, and sends the clients one or more policies having a resource usage quota that limits the amount of the resource that the client can use. When a client receives a request to perform a task that requires a shared resource, before running the task, the client determines its own usage of the resource and terminates the task if running the task will exceed the quota limit of the shared resource.
