\frametitle{A passive SSL fingerprinter}
CSIRT's rationale for collecting TLS handshakes:
\begin{itemize}
\item Pivot on additional data points
\item Find owners of IP addresses
\item Detect usage of CIDR blocks
\item Detect vulnerable systems
\item Detect compromised services
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Objectives}
History of links between:
\begin{itemize}
\item x509 certificates (And therefore their fields)
\item Ports
\item IP address
\item Client (ja3)
\item Server (ja3s)
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Problem statement}
\begin{itemize}
\item CIRCL already offers a similar service based on SSLDump
\item SSLDump needs some love - maintaining it is hard
\item Alternatives do not span the entire TLS Handshake (Salesforce's ja3)
\item TCP reassembly is not an easy problem to solve (Cloudfare uses tshark)
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{sensor-d4-tls-fingerprinting}
Main features:
\begin{itemize}
\item Take over SSLDump's duty
\item written in Golang
\item uses Go packet for tcp reassembly and spans whole handshake
\item ja3, ja3s, certificates, ip src / dst, port src / dst, TLSH
\end{itemize}
Current caveats:
\begin{itemize}
\item Support for TLS 1.3 pending
\item Reassembly requires RAM
\end{itemize}
