Abstract
Disclosed are exemplary aspects of systems and methods for detection of phishing scripts. An exemplary method comprises: generating a bytecode of a script; computing a hash sum of the generated bytecode; determining a degree of similarity between the hash sum of the bytecode and hash sums in one or more groups of hash sums of known phishing scripts; identifying at least one group of hash sums that contains a hash sum whose degree of similarity with the hash sum of the bytecode is within a threshold; determining a coefficient of compactness of the identified group of hash sums and a coefficient of trust of the identified group of hash sums; and determining whether the script is a phishing script based on the degree of similarity, the coefficient of compactness and the coefficient of trust.
