Abstract

Ucjenjivački softver (engl. Ransomware) je vrsta malicioznog programa ili koda koja pokušava doprijeti do osobnih podataka krajnjih korisnika terminalnih uređaja. Krajnji cilj su korisnici te okorištavanje njima u financijskom smislu. Ucjenjivački softver radi na principu zaključavanja terminalnog uređaja te kriptiranja korisničkih podataka koji se nalaze na memorijskoj pohrani terminalnih uređaja, nakon čega oni postaju nedostupni krajnjem korisniku. Od korisnika se zatim iznuđuje novac raznim kanalima, vrlo često putem kriptovaluta, kako bi povratili, tj. otkupili vlastite podatke. U radu je ucjenjivački softver opisan pored ostalog zlonamjernog softvera te su iznesene razlike između podvrsti zaključavajućeg i kriptografskog ucjenjivačkog softvera uz njihove temeljne načine funkcioniranja. Uspoređene su karakteristike nekih od aktualnih i poznatijih ucjenjivačkih softvera poput WannaCry i Petya te je cjelovita usporedba izražena pomoću tabličnog prikaza. Upravo činjenice i iznesene karakteristike te statistički pokazatelji stvaraju sliku i otvaraju svijest o problemu ucjenjivačkog softvera. Iz tih praktičnih razloga na kraju rada nalaze se savjeti i preporuke kako zaštiti terminalni uređaj te kako promijeniti obrasce ponašanja i loše navike korištenja terminalnih uređaja jer sigurnosni rizici drastično opadaju s kvalitetnom prevencijom i samim prestankom širenja ucjenjivačkog softvera.

Abstract (english)

Ransomware is a kind of malicious program or a code that tries reach and impact to the personal data of end-users of terminal devices. The ultimate goal are end users and exploiting them in a financial sense through blackmail. The blackmailing software works on the principle of locking terminal devices and encrypting user data stored on the same devices after which they become unavailable to the end user. In the second stage of attack money is drawn from the end users through various channels, very often through cryptocurrency to regain or repurchase their own data. In this paper, blackmail software is described beside other malicious software and the differences between the underlying locking and cryptographic blackmail software are outlined with their basic ways of functioning. The features of some of the current and well known blackmailing software such as WannaCry and Petya have been compared, and a complete comparison is expressed by a table. The facts and the characteristics that are presented, as well as the statistical indicators, create a picture and open the awareness of the main problem, named blackmailing software. For these practical reasons at the end of the work, there are tips and recommendations on how to protect the terminal device and how to change behavioral patterns and bad habits of using these existing terminal devices because security risks drastically fall off with quality prevention and with the end of the blackmail software expansion.
