\maketitle
\end{frame}
\begin{frame}
\frametitle{Problem statement}
\begin{itemize}
\item CSIRTs (or private organisations) build their {\bf own honeypot, honeynet or blackhole monitoring network}
\item Designing, managing and operating such infrastructure is a tedious and resource intensive task
\item {\bf Automatic sharing} between monitoring networks from different organisations is missing
\item Sensors and processing are often seen as blackbox or difficult to audit
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Objective}
\begin{itemize}
\item Based on our experience with
MISP\footnote{\url{https://github.com/MISP/MISP}} where sharing
played an important role, we transpose the model in D4 project
\item Keeping the protocol and code base {\bf simple and minimal}
\item Allowing every organisation to {\bf control and audit their own sensor network}
\item Extending D4 or {\bf encapsulating legacy monitoring protocols} must be as simple as possible
\item Ensuring that the sensor server has {\bf no control on the sensor} (unidirectional streaming)
\item Don't force users to use dedicated sensors and allow {\bf flexibility of sensor support} (software, hardware, virtual)
\end{itemize}
\end{frame}

contribute to a public dataset without running their own D4 server:
\begin{itemize}
\item [\checkmark] Blackhole DDoS
\item [\checkmark] Passive DNS
\item [\checkmark] Passive SSL
\item BGP mapping
\item egress filtering mapping
\item Radio-Spectrum monitoring: 802.11, BLE, etc.

\frametitle{D4 meta header}
\framesubtitle{Meta types}
D4 header includes an easy way to {\bf extend the protocol} (via type 2) without altering the format. Within a D4 session, the initial D4 packet(s) type 2 defines
the custom headers and then the following packets with type 254 is the custom data encapsulated.

\frametitle{D4 server}
\begin{itemize}
\item D4 core server\footnote{\url{https://github.com/D4-project/d4-core}} is a complete server to handle clients (sensors) including the decapsulation of the D4 protocol, control of sensor registrations, management of decoding protocols and dispatching to adequate decoders/analysers.
\item D4 server is written in Python 3.6 and runs on standard GNU/Linux distribution.
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{D4 server - management interface}
The D4 server provides a {\bf web interface} to manage D4 sensors, sessions and analyzer.
\begin{itemize}
\item Get Sensors status, errors and statistics
\item Get all connected sensors
\item Manage Sensors (stream size limit, secret key, ...)
\item Manage Accepted types
\item UUID/IP blocklist
\item Create Analyzer Queues
\end{itemize}

{\bf A distributed Network telescope to observe DDoS attacks}
\end{center}
\vspace{10pt}
\begin{center}
\includegraphics[width=.7\textwidth]{eventhorizon.png}
\end{center}
\end{frame}
\begin{frame}
\frametitle{Motivation}
DDoS Attacks produce an observable side-effect:
\begin{center}
\scalebox{0.8}{\input{bsvol.tex}}
\end{center}
\end{frame}
\begin{frame}
\frametitle{What can be derived from backscatter traffic?}
\begin{itemize}
\item External point of view on ongoing Denial of Service attacks:
\begin{itemize}
\item {\bf Confirm} if there is a DDoS attack
\item {\bf Recover} time line of attacked targets
\item {\bf Confirm} which services (DNS, webserver, $\dots$)
\item {\bf Observe} Infrastructure changes
\end{itemize}
\item {\bf Assess the state of an infrastructure under denial of service attack}
\begin{itemize}
\item {\bf Detect} failure/addition of intermediate network equipments, firewalls, proxy servers etc
\item {\bf Detect} DDoS mitigation devices
\end{itemize}
\item Create models of DoS/DDoS attacks
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{D4 in this setting}
D4 - for data collection and processing:
\begin{itemize}
\item {\bf provide} various points of observation in non contiguous address space,
\item {\bf aggregate} and {\bf mix} backscatter traffic collected from D4 sensors,
\item {\bf perform} analysis on big amount of data.
\end{itemize}
D4 - from a end-user perspective:
\begin{itemize}
\item {\bf provide} backscatter analysis results,
\item {\bf provide} daily updates,
\item {\bf provide} additional relevant (or pivotal) information (DNS, BGP, etc.),
\item {\bf provide} an API and search capabilities.
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{First release}
\begin{itemize}
\item[\checkmark]
analyzer-d4-pibs\footnote{\url{https://github.com/D4-project/analyzer-d4-pibs}}, an analyzer for a D4 network sensor:
\begin{itemize}
\item {\bf processes} data produced by D4 sensors (pcaps),
\item {\bf displays} potential backscatter traffic on standard output,
\item {\bf focuses} on TCP SYN flood in this first release.
\end{itemize}
\end{itemize}
\end{frame}
\begin{frame}
\begin{center}
{\bf Passive DNS}
\end{center}
\end{frame}
\begin{frame}
\frametitle{Problem statement}
\begin{itemize}
\item CIRCL (and other CSIRTs) have their own passive DNS\footnote{\url{https://www.circl.lu/services/passive-dns/}} collection mechanisms
\item Current {\bf collection models} are affected with DoH\footnote{DNS over HTTPS} and centralised DNS services
\item DNS answers collection is a tedious process
\item {\bf Sharing Passive DNS stream} between organisation is challenging due to privacy
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Potential Strategy}
\begin{itemize}
\item Improve {\bf Passive DNS collection diversity} by being closer to the source and limit impact of DoH (e.g. at the OS resolver level)
\item Increasing diversity and {\bf mixing models} before sharing/storing Passive DNS records
\item Simplify process and tools to install for {\bf Passive DNS collection by relying on D4 sensors} instead of custom mechanisms
\item Provide a distributed infrastructure for mixing streams and filtering out the sharing to the validated partners
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{First release}
\begin{itemize}
\item[\checkmark]
analyzer-d4-passivedns\footnote{\url{https://github.com/D4-project/analyzer-d4-passivedns}}, an analyzer for a D4 network sensor:
\begin{itemize}
\item {\bf processes} data produced by D4 sensors (in passivedns CSV format\footnote{\url{https://github.com/gamelinux/passivedns}}),
\item{\bf ingests} these into a {\bf Passive DNS server} which can be queried later to search for the Passive DNS records,
\item{\bf provides} a lookup server (using on
redis-compatible backend) that is a Passive DNS REST server compliant to the Common Output Format\footnote{\url{https://tools.ietf.org/html/draft-dulaunoy-dnsop-passive-dns-cof-04}}.
\end{itemize}

\begin{frame}
\frametitle{A passive SSL fingerprinter}
CSIRT's rationale for collecting TLS handshakes:
\begin{itemize}

\item {\bf find} owners of IP addresses,
\item {\bf detect} usage of CIDR blocks,
\item {\bf detect} vulnerable systems,
\item {\bf detect} compromised services,
\item {\bf detect} key material reuse,

\item ports,
\item IP address,
\item client (ja3),
\item server (ja3s),
\end{itemize}

``JA3 is a method for creating SSL/TLS client fingerprints that should be easy to produce on any platform and can be easily shared for threat intelligence.''\footnote{https://github.com/salesforce/ja3}
\end{displayquote}
\end{frame}
\begin{frame}

{\bf Collect} and {\bf store} x509 certificates and TLS sessions:
\begin{itemize}
\item Public keys type and size,
\item moduli and exponents,
\item curves parameters.
\end{itemize}
{\bf Detect} anti patterns in crypto:
\begin{itemize}
\item Shared Public Keys,
\item Moduli that share one prime factor,
\item Moduli that share both prime factor,
\item Small factors,
\item Nonces reuse / common preffix or suffix, etc.
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{First release}
\begin{itemize}
\item[\checkmark] sensor-d4-tls-fingerprinting
\footnote{\url{github.com/D4-project/sensor-d4-tls-fingerprinting}}:

\item {\bf Interconnecting private D4 sensor networks} with other D4 sensor networks (sharing to partners filtered stream)
\item {\bf Previewing datasets} collected in D4 sensor network and providing {\bf open data stream} (if contributor agrees to share under specific conditions)
\item {\bf Leverage MISP sharing communities} to augment Threat
Intelligence, and provide accurate metrology.

\begin{frame}
\frametitle{Get in touch if you want to join the project, host a sensor or contribute}
\begin{itemize}
\item Collaboration can include research partnership, sharing of collected streams or improving the software.
\item Contact: info@circl.lu
