Cyber-security has evolved to a key priority for Qatar and all nations over the world. Malicious actors from anywhere misuse the cyberspace to perpetrate various crimes such as phishing, Cyber-blackmailing, Cyber-bullying, and communicating or planning terrorist attacks using social media. For instance, there is a tendency from these cybercriminals to use similar writing styles in their messages, which makes it possible for security experts to detect and stop these threats using natural language processing techniques (NLP) as explained in the IBM Security Intelligence online news source. In that context, this project aims at developing author profiling resources and tools for the Arabic language and applying them to cyber-security as an instrument for fighting against cyber-crimes. More specifically, author profiling can be useful for forensics investigations to narrow the set of potential authors when receiving a threat message.
