摘要： An unlabeled sample is classified using clustering. A set of samples containing labeled and unlabeled samples is established. Values of features are gathered from the samples contained in the datasets and a subset of features are selected. The labeled and unlabeled samples are clustered together based on similarity of the gathered values for the selected subset of features to produce a set of clusters, each cluster having a subset of samples from the set of samples. The selecting and clustering steps are recursively iterated on the subset of samples in each cluster in the set of clusters until at least one stopping condition is reached. The iterations produce a cluster having a labeled sample and an unlabeled sample. A label is propagated from the labeled sample in the cluster to the unlabeled sample in the cluster to classify the unlabeled sample.

摘要： Embodiments in accordance with the invention install a primary security browser extension first in the browser event notification order list and a secondary security browser extension last in the event notification order list. On receipt of a user data event including user confidential data at the primary security browser extension, the user confidential data is obfuscated by the primary security browser extension and the user data event including the obfuscated data is released to a next browser extension in the browser event notification order list. Upon receipt of the user data event at the secondary security browser extension, the obfuscated data is restored with the original user confidential data and the user data event is released for further processing.

摘要： Described herein are systems, methods, and software to enhance the management of responses to incidents. In one example, a method of improving incident response comprises identifying an incident in an information technology (IT) environment associated with a first entity of a plurality of entities, and identifying action implementation information related to the incident. The method further anonymizes the action implementation information for the incident, and determines action suggestions based at least on the anonymized action implementation information.

摘要： A method and system detect buffer overflows and RLIBC attacks by determining if a critical call initiating function is a “potential threat”. In one embodiment, a critical call initiating function is considered a potential threat if the value of the return address of the critical call initiating function points to a location in memory between the location of the highest Thread Environment Block (TEB) or Process Environment Block (PEB) and the location of the lowest Thread Environment Block (TEB) or PEB. In another embodiment, a critical call initiating function making a call to a predefined critical operating system function is considered a potential threat if the value of the return address of the critical call initiating function points to the beginning of a new function with a zero offset.
