There are about 100,000 cyber-attacks in Poland daily, according to the research conducted between Q4 2016 and Q1 2017 by F-Secure. Over 65% (65,493) of all cyber-attacks come from Russia. The runner-up is Germany, followed by Poland, the Netherlands and Belgium. These attacks are made via badly-secured server rooms in previously mentioned countries, but hackers can be localised in any country all over the world. Cybercriminals use botnets, malware and ransomware to attack companies, institutions and private individuals. The victims are usually careless users, or those who do not use any firewalls or anti-virus software.
