During the course, students will learn - where and how to find the information you need; - What tools can make it easier to find information; - how to circumvent certain restrictions on access to data; - basic principles of cybersecurity and online hygiene. This is not an in-depth course on OSINT. It's a point training with a list of specific methods that takes a small amount of time and allows you to quickly start an investigation using relevant tools. Students will be able to learn how to search for information by nickname, photo, work with state registers, business tools, search for geolocation, and determine the time of a crime. To provide more in-depth knowledge, LingvaLexa's cyber specialists conduct weekly and monthly courses, depending on the request. This course is free of charge.
