In addition, better understanding on threats patterns is a key feature for cyber threats prevention, detection, and management and for enhancing defenses. In this work, we study different aspects of emerging threats in the wild shared by 160,000 global participants form all industries. First, we perform an exploratory data analysis of the collected cyber threats. We investigate the most targeted countries, most common malwares and the distribution of attacks frequency by localisation. Second, we extract attacks{\textquoteright} spreading patterns at country level. We model these behaviors using transition graphs decorated with probabilities of switching from a country to another. Finally, we analyse the extent to which cyber threats have been affected by the COVID-19 outbreak and sanitary measures imposed by governments to prevent the virus from spreading. {\textcopyright} 2021 IEEE.}, keywords = {Attack analysis, Case-studies, Computer viruses, COVID-19, Crime, Cybe attack analyse, Cybe threat forecasting, Cyber attacks, Cyber threats, Cyber-attacks, Cyber-crimes, Information analysis, Network security, Spatialoral data analyse for cybe-crime analyse, Threat intelligence, Viruses}, doi = {10.1109/ISI53945.2021.9624677}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85123484404\&doi=10.1109\%2fISI53945.2021.9624677\&partnerID=40\&md5=729113fca1f2d9817bbaa46a6f5d0036}, author = {Cherqi, O. and Hammouchi, H. and Ghogho, M. and Benbrahim, H.} } @conference {Cherqi201879, title = {Analysis of hacking related trade in the darkweb}, booktitle = {2018 IEEE International Conference on Intelligence and Security Informatics, ISI 2018}, year = {2018}, pages = {79-84}, doi = {10.1109/ISI.2018.8587311}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85061056307\&doi=10.1109\%2fISI.2018.8587311\&partnerID=40\&md5=3f2dbe2fc3377bce7e35dd18dfb3710f}, author = {Cherqi, O. and Mezzour, G. and Ghogho, M. and El Koutbi, M.} }
