Query: All Infections are Not Created Equal: Time-Sensitive Prediction of
  Malware Generated Network Attacks   Many techniques have been proposed for quickly detecting and containing
malware-generated network attacks such as large-scale denial of service
attacks; unfortunately, much damage is already done within the first few
minutes of an attack, before it is identified and contained. There is a need
for an early warning system that can predict attacks before they actually
manifest, so that upcoming attacks can be prevented altogether by blocking the
hosts that are likely to engage in attacks. However, blocking responses may
disrupt legitimate processes on blocked hosts; in order to minimise user
inconvenience, it is important to also foretell the time when the predicted
attacks will occur, so that only the most urgent threats result in
auto-blocking responses, while less urgent ones are first manually
investigated. To this end, we identify a typical infection sequence followed by
modern malware; modelling this sequence as a Markov chain and training it on
real malicious traffic, we are able to identify behaviour most likely to lead
to attacks and predict 98\% of real-world spamming and port-scanning attacks
before they occur. Moreover, using a Semi-Markov chain model, we are able to
foretell the time of upcoming attacks, a novel capability that allows
accurately predicting the times of 97% of real-world malware attacks. Our work
represents an important and timely step towards enabling flexible threat
response models that minimise disruption to legitimate users.
