Denis Periša (born July 23, 1983) is a political activist, whistle blower and computer hacker from Šibenik, Croatia. He founded the computer security website Jezgra.org in 1997. He was convicted and criminally charged in September 1999.[1][2][3][4] He was forbidden the use of any form of computer system or the internet for hacking the e-mail of politician Veselin Pejnović while planting a backdoor to his network. In 2005, he founded ŠI-WIFI wireless, an organization that was formed for his town.[5][6]
Law and order
During the COVID-19 pandemic, as part of a group, Periša made 3D-printed face shields for the local hospitals in Drniš and Knin.[7][8][9][10][11][12]
Beginning in 2017, Periša worked on cases for local police and DORH (the state attorney) by coming across and prosecuting online bullies and people spreading hate with the possible use of physical violence towards others. He spoke about how to report such crimes on national television.[13][14][15][16] Shortly after that, he was threatened and put under police protection.[17][18] Later on, he searched for fugitive Ivica Todorić and the servers Todorić used.[19]
Political standoff
In August 2010, Periša claimed that he blew the whistle on the Social Democratic Party (SDP) for overspending the local municipal budget on a wireless network.[20] He informed the city mayor Mayor Ante Županović privately,[21] who replied with little interest.[22] Periša then publicly confronted Županović[23] to accuse him of stealing public money.[24]
A local newspaper tested out the existing municipal wireless network in 2013 and concluded that Periša was right, and it was not working.[25] After the Croatian Democratic Union (HDZ) took power, Periša was appointed to rebuild and maintain the local city wireless network, which he did in late 2014.[26]
Anonymous group
After a decade of claiming to lead hacking groups, Periša claims he finally joined the Anonymous group firstly fighting against ACTA and similar acts.[27] He encourages people to use the Linux OS for supposedly lower power consumption and better power savings.[28] On June 4, 2015, Periša appeared on a Skype interview for the Alter EGO show talking about the internet and anonymously representing himself as one of the internet freedom fighters.[29]
