Abstract
JavaScript biblioteke omogućavaju veću brzinu i jednostavnost programiranja Web sadržaja. Kako bi se prikrile know how tajne i maliciozan kod koristi se obfuskacija. Obfusciranje je namjerni čin kojim se nešto preoblikuje kako bi se teže razumjelo. Često korišteni obfuskatori poput obfuscate.io pružaju mnogo metoda koje proizvode različite obfuscirane verzije istog izvornog koda. Sličnu funkcionalnost obfuskaciji posjeduje i minifikacija koja također pretvara originalni kod u oblik koje je teži za razumjeti, no za razliku od obfuskacije, minifikacija smanjuje veličinu koda čime ga ubrzava te joj je to primarna funkcionalnost. U ovom radu dan je pregled obfuskacije i minifikacije te metoda koji alati za obfusciranje i minificiranje koriste. Razvijen programski alat pomoću parametara poput regexa, entropije i veličine riječi detektira i razlikuje minificirane i obfuscirane JavaScript biblioteke. Prikazan je rezultat izvođenja programskog alata nad bazom podataka koja sadrži sve naslovne stranice koje su u hrvatskoj domeni. Rezultati prikazuju veliku prisutnost minificiranih te malu količinu obufsciranih JavaScript biblioteka. Ovakvo automatizirano detektiranje pokazalo se iznimno bržim i u nekim slučajevima boljom od ručnog detektiranja obfuskacije i minifikacije.
Abstract (english)
JavaScript libraries allow for faster and easier programming of Web content. In order to conceal the know-how secrets and malicious code, obfuscation is used. Obfuscation is a deliberate act of reshaping something to make it harder to understand. Commonly used obfuscators such as obfuscate.io provide many methods that produce different obfuscated versions of the same source code. Minification has similar functionality to obfuscation, which also turns the original code into a form that is harder to understand, but unlike obfuscation, minification reduces the size of the code, which speeds it up, and is its primary functionality. This paper provides an overview of obfuscation and minification and the methods used by obfuscation and minification tools. The developed software tool uses parameters such as regex, entropy and word size to detect and distinguish minified and obfuscated JavaScript libraries. The result of running the software tool on a database containing all title pages that are in the Croatian domain is presented. The results show a high presence of minified and a small amount of obfuscated JavaScript libraries. This automated detection has proven to be extremely faster and in some cases better than manual detection of obfuscation and minification.
