A system and method for preventing access to potentially malicious network destinations. The method includes determining a plurality of network destinations and indicators of the plurality of network destinations including an indicator of a first network destination. A plurality of feature vectors are generated based on the plurality of network destinations including a first feature vector based on the first network destination. Access by a user via a computing device to a second network destination is detected. A second feature vector is generated, and an indicator is determined based on the second network destination. The second feature vector is compared to the plurality of feature vectors. The access by the user to the second network destination is blocked based on the indicator of the first network destination, the indicator of the second network destination, and the comparison of the second feature vector to the plurality of feature vectors.

Network attack prevention systems and methods

A method and system for updating and applying a ruleset used for determining and mitigating malware threats. Communications of computing devices are monitored and first data file extracted. A first and second set of features are extracted. A first rule is applied to the first set of features of the first data file to determine a non-match. A second rule is applied to the second set of features to determine a match. A third rule is generated based on the first set of features, non-match, and match. Communications of a particular computing device are monitored and second data file extracted. A first set of features of the second data file are extracted. The third rule is applied to the first set of features of the second data file to determine a match. The second data file is disabled, blocked, or deleted based the match determination by the third rule.
