Denis Periša (born July 23, 1983) is a political activist, whistle blower and computer hacker from Šibenik, Croatia. He was convicted and criminally charged[1][2][3][4] in September 1999. He was forbidden to use computer systems or internet for hacking e-mail of politician Veselin Pejnović[5] and planting backdoor to his network. He founded the computer security website Jezgra.org in 1997 that is still active today. Founder of ŠI-WIFI wireless organization for his town in late 2005.[6][7] Denis also claims himself to be a DJ,[8] photographer[9] and recently a writer of the book called "My first suicide", which has yet to be released.[10]
Background
Childhood
Periša was raised in Šibenik, Croatia, with his sister Tina. Periša became interested in computers at an early age, programming in Basic by age thirteen, doing small games on Commodore 128, and forming hacking groups at age fifteen in local computer club.[citation needed]
Medical condition
In early childhood he had a medical condition with his right lung.[11] After surgery he was unable to vaccinate against a common illness and shortly after he got Tetanus after a cat scratched him.[12][13] He was saved by a former military officer of Yugoslav army (JNA) who ordered a military helicopter for him to be sent from Šibenik to Zagreb for emergency and life saving medical care. After many years he fully recovered but the physical scars of surgery and Tracheotomy on his neck is left as a reminder of near death experience. He acquired very asocial behavior due to lack of socialization.
Education
He often skipped school and didn't like to attend it. After he was arrested his mom was delighted that he shows interest in computer science and called the local firm "Ciam" which said "we cannot teach your son anything more, he could train our technicians".[14] He went to numerous schools. He found photography to be most interesting skill he could learn but he dropped out after 2 years, never graduating high school.
Music
Denis has a lifelong interest in hip-hop music, performing as a DJ in a band in 2006.[15] Later he was a DJ[16] in gigs at nearby towns and he is the co-founder of "Zadar Muzika" with many hosted events.[17][18] Denis also started making his own rap songs and doing hip-hop production with performers from former Yugoslavia countries.[19]
Activism
Law and order
Beginning in 2017, Denis worked on numerous cases for local police and DORH (State Attorney) by coming across and prosecuting online bullies and people spreading hate with possible use of physical violence towards others. Starting with man that that endorsed another for killing his parents and encouraging others to do same with cops. He spoke about how to report such crimes on National Television.[20][21][22][23] Shortly after he was threatened and was put under police protection.[24][25] Later on he was searching for fugitive Ivica Todorić and his online servers.[26]
Computer security
Denis founded the computer security website Jezgra.org at age 15. Throughout his life he was involved in public speaking and hacktivism[27] along with activism.[28]
He claims he was guilty for various online scandals like hacking folk music websites.[29] He also claims his computer skills were recognized after building firmware that could improve wireless strength of device (SE515 by Siemens) that was popular and very spread out in Croatia and that part of Europe.[30]
He was often critical about Croatia secret services that they have no clue what is going on and are not prepared for current century.[31]
Political standoff
In August 2010, Denis in his own words claims he publicly whistle blew Social Democratic Party (SDP) for overspending the local city budget on town wireless network saying that they are throwing away money and giving it to their party member and it will all be for nothing.[32] He privately mailed the city mayor[33] on which the mayor replied rough with no interest.[34] That gave Denis steam to publicly confront city Mayor Ante Županović [35] and said they are stealing money.[36]
He claims he turned out to be right in 2013 after local news paper tested out existing wireless network and concluded it was not working.[37] After local political scene changed to Croatian Democratic Union (HDZ) it became apparent that Denis will be next man in charge of rebuilding and maintaining local city wireless as most competent. So he did just that in late 2014.[38]
Anonymous
After decade of claiming to lead hacking groups Denis claims he finally joined Anonymous group firstly fighting against ACTA and similar acts.[39] He endorses and motivate people to start using Linux OS if nothing then for lower power consumption and better power saving.[40] On June 4, 2015 Denis appeared on a skype interview for "Alter EGO" show talking about internet and anonymous representing himself as one of internet freedom fighters.[41]
Atheism
Denis is declared atheist and is strongly opposed to Catholic church. Lately Denis introduced himself to public as one of atheist activist in his home town. -"Atheist wing of Croatia in starts its branch in town Šibenik".[42]
ACTA
In early 2012 Denis was strongly against ACTA and similar acts claiming that if we start to censor Internet, we can say goodbye to democracy.[43]
Public speaking

In 2014 Denis started public speaking on some conferences. He was first invited to lecture in Split, Croatia on STFF (Split Film Festival) as a guest speaker with subject "HACKING AND THE (PRIVACY) PROTECTION" lasting two hours.[44][45][46][47] After which he gave interview with same subject to H-Alter magazine with subject "Table to table via smartphones" where he commented all his previous work along with recent WikiLeaks arrests.[48]
