Abstract

A method is provided in one example embodiment that includes receiving message sender traits associated with email senders, and receiving a dataset of known malware identifiers and network addresses from a spamtrap. The message sender traits may include behavior features and/or content resemblance factors in various embodiments. The method further includes classifying the email senders as malicious or benign based on the behavior features, and further classifying the malicious senders by malware identifiers based on similarity of content resemblance factors and the dataset of known malware identifiers and network addresses. In certain specific embodiments, a supervised classifier, such as a support vector machine, may be used to classify the malicious senders by malware identifiers.
