\title{AIL Framework for Analysis of Information Leaks}
\subtitle{data mining - website and darkweb correlation}
\institute{info@circl.lu}
\date{\today}
\begin{document}
\begin{frame}[t,plain]
\titlepage
\end{frame}
\begin{frame}
\frametitle{Privacy, AIL and GDPR}
\begin{itemize}
\item Many modules in AIL can process personal data and even special categories of data as defined in GDPR (Art. 9).
\item The data controller is often the operator of the AIL framework (limited to the organisation) and has to define {\bf legal grounds for processing personal data}.
\item To help users of AIL framework, a document is available which describe points of AIL in regards to the regulation\footnote{\url{https://www.circl.lu/assets/files/inform
ation-leaks-analysis-and-gdpr.pdf}}.
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Potential legal grounds}
\begin{itemize}
\item {\bf Consent of the data subject} is in many cases not feasible in practice and often impossible or illogical to obtain (Art. 6(1)(a)).
\item Legal obligation (Art. 6(1)(c)) - This legal ground applies mostly to CSIRTs, in accordance with the powers and responsibilities set out in CSIRTs mandate and with their constituency, as they may have the legal obligation to collect, analyse and share information leaks without having a prior consent of the data subject.
\item Art. 6(1)(f) - Legitimate interest - Recital 49 explicitly refers to CSIRTs’ right to process personal data provided that they have a legitimate interest but not colliding with fundamental rights and freedoms of data subject.
\end{itemize}
\end{frame}
\section{Objectives}
\begin{frame}
\frametitle{Our objectives}
\begin{itemize}
\item Show how to use and extend an open source tool to monitor web pages, pastes, forums and hidden services
\item Explain challenges and the design of the AIL open source framework
\item Learn how to create new modules
\item Learn how to use, install and start AIL
\item {\bf Supporting investigation using the AIL framework}
\end{itemize}
\end{frame}
\section{AIL Framework}
\begin{frame}
\frametitle{From a requirement to a solution: AIL Framework}
\large{History:}
\begin{itemize}
\item AIL initially started as an \textbf{internship project} (2014) to evaluate the feasibility to automate the analysis of (un)structured information to find leaks.
\item In 2019, AIL framework is an \textbf{open source software} in Python. The software is actively used (and maintained) by CIRCL and many organisations.
\end{itemize}

\end{figure}
\end{frame}
\begin{frame}
\frametitle{Sources of leaks: Paste monitoring}
\begin{itemize}
\item Example: \url{http://pastebin.com/}
\begin{itemize}
\item Easily storing and sharing text online
\item Used by programmers and legitimate users
\item[] $\to$ Source code \& information about configurations
\end{itemize}
\pause
\item Abused by attackers to store:
\begin{itemize}
\item List of vulnerable/compromised sites
\item Software vulnerabilities (e.g. exploits)
\item Database dumps
\item[] $\to$ User data
\item[] $\to$ Credentials
\item[] $\to$ Credit card details
\item More and more ...
\end{itemize}
\end{itemize}

\frametitle{Examples of pastes}
\begin{figure}
\includegraphics[scale=0.32, angle=0]{images/pastes-ex.png}
\end{figure}
\end{frame}
\begin{frame}
\frametitle{Why so many leaks?}
\begin{itemize}
\item Economical interests (e.g. Adversaries promoting services)
\item Political motives (e.g. Adversaries showing off)
\item Collaboration (e.g. Criminals need to collaborate)
\item Operational infrastructure (e.g. malware exfiltrating information on a pastie website)
\item Mistakes and Errors
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Are leaks frequent?}
\begin{center}
\Large{Yes!}\\ and we have to deal with this as a CSIRT.
\end{center}
\begin{itemize}
\item {\bf Contacting companies or organisations} who did specific accidental leaks
\item {\bf Discussing with media} about specific case of leaks and how to make it more practical/factual for everyone
\item Evaluating the economical market for cyber criminals (e.g. DDoS booters\footnote{\url{https://github.com/D4-project/}} or reselling personal information - reality versus media coverage)
\item Analysing collateral effects of malware, software vulnerabilities or exfiltration
\end{itemize}
\begin{center}
$\rightarrow$ And it's important to detect them automatically.
