Recent incidents of data breaches call for organizations to proactively
identify cyber attacks on their systems. Darkweb/Deepweb (D2web) forums and
marketplaces provide environments where hackers anonymously discuss existing
vulnerabilities and commercialize malicious software to exploit those
vulnerabilities. These platforms offer security practitioners a threat
intelligence environment that allows to mine for patterns related to
organization-targeted cyber attacks. In this paper, we describe a system
(called DARKMENTION) that learns association rules correlating indicators of
attacks from D2web to real-world cyber incidents. Using the learned rules,
DARKMENTION generates and submits warnings to a Security Operations Center
(SOC) prior to attacks. Our goal was to design a system that automatically
generates enterprise-targeted warnings that are timely, actionable, accurate,
and transparent. We show that DARKMENTION meets our goal. In particular, we
show that it outperforms baseline systems that attempt to generate warnings of
cyber attacks related to two enterprises with an average increase in F1 score
of about 45% and 57%. Additionally, DARKMENTION was deployed as part of a
larger system that is built under a contract with the IARPA Cyber-attack
Automated Unconventional Sensor Environment (CAUSE) program. It is actively
producing warnings that precede attacks by an average of 3 days.
