  The VAST Challenge 2020 Mini-Challenge 1 requires participants to identify
the responsible white hat groups behind a fictional Internet outage. To address
this task, we have created a visual analytics system named CA2: Cyber Attacks
Analytics. This system is designed to efficiently compare and match subgraphs
within an extensive graph containing anonymized profiles. Additionally, we
showcase an iterative workflow that utilizes our system's capabilities to
pinpoint the responsible group.
