Is Telegram the new Dark Web? That is the main question during this interactive presentation. Due to specific functionalities, Telegram has developed into much more than a chat application and this has not gone unnoticed by criminals. Partly due to the strict privacy and security options and the extensive options for group chats, the use of Telegram has not only increased exponentially, but there has also been a strong growth in criminal activities on Telegram. In this interactive presentation we will take you through the dark sides of Telegram, full of drugs, weapons and more, using concrete examples. During this interactive presentation we not only provide an insight into the criminal activities that take place on Telegram, we would also like to discuss the practical and legal possibilities and limitations for investigation by Law Enforcement. We challenge you to share your thoughts about possible solutions to reduce criminal activities on Telegram.
