The IT Army of Ukraine is a community of tech specialists from all over the world who united after the start of a full-scale invasion of Ukraine by Russia. Hundreds of cyberattacks were carried out, and various secret databases, websites of state bodies, and key enterprises were hacked. The cyber community organizes multimillion-dollar fundraisers for the needs of the military and refugees and also creates useful applications for Ukrainian citizens. Volunteers spend 15-20 hours a week on volunteer projects, that is like a part-time job.
