20130347114 | SYSTEM AND METHOD FOR MALWARE DETECTION - Systems and methods for malware detection techniques, which detect malware by identifying the C&C communication between the malware and the remote host. In particular, the disclosed techniques distinguish between request-response transactions that carry C&C communication and request-response transactions of innocent traffic. Individual request-response transactions may be analyzed rather than entire flows, and fine-granularity features examined within the transactions. As such, these methods and systems are highly effective in distinguishing between malware C&C communication and innocent traffic, i.e., in detecting malware with high detection probability and few false alarms. | 12-26-2013 |
20140359761 | SYSTEM AND METHOD FOR MALWARE DETECTION LEARNING - Malware detection techniques that detect malware by identifying the C&C communication between the malware and the remote host, and distinguish between communication transactions that carry C&C communication and transactions of innocent traffic. The system distinguishes between malware transactions and innocent transactions using malware identification models, which it adapts using machine learning algorithms. However, the number and variety of malicious transactions that can be obtained from the protected network are often too limited for effectively training the machine learning algorithms. Therefore, the system obtains additional malicious transactions from another computer network that is known to be relatively rich in malicious activity. The system is thus able to adapt the malware identification models based on a large number of positive examples—The malicious transactions obtained from both the protected network and the infected network. As a result, the malware identification models are adapted with high speed and accuracy. | 12-04-2014 |
