FinnSec Security is a Finnish hacker group who claims responsibility for the 2016 attacks against KELA and the Finnish Ministry of Defense's websites; all claims of which are unfounded. The group also claims responsibility for taking down Finnish state ICT centre, State Reporting System and Finnish social insurance institute KELA. National Bureau of Investigation (NBI) arrested 3 young men during the proceeding criminal investigation.
FinnSec Security's original Twitter account (@FinnSecSecurity) is frozen. Originally the group claimed to be from Russia. Shortly after the claim was made, Finnish police reported this to be false.
The founder and leader of the group "JQuery" got arrested again for similar charges, having infected over 3500 computers by spreading malware via YouTube videos. The groups name was soon changed to UnrealSecurity. The group made a homepage dubbed "unrealsecurity.net", however the leader got arrested once again in 2017 and the site is left without an administrator
