These&amp;nbsp;worms were actively spread from 00:00 UTC July 19, 2001 to 00:00 UTC July&amp;nbsp;20, 2001 and on March 19, 2004, at approximately 8:45 p.m. Pacific Standard&amp;nbsp;Time (PST) respectively. Here we give a new way of treating these epidemics&amp;nbsp;using Dagum-II sigmoid function [1]-[7].&lt;/p&gt;

Welchia worm and&amp;nbsp;Cryptolocker ransomware have a long growing phase in contrast to many other&amp;nbsp;threats. In September 2013 the CryptoLocker malware starting its invasion&amp;nbsp;using mainly P2P ZeuS (aka Gameover ZeuS) malware. CryptoLocker’ main&amp;nbsp;aim was to receive money from the unsuspecting victims for decrypting their&amp;nbsp;files. Welchia worm uses a vulnerability in the Microsoft remote procedure&lt;br /&gt;
call service. Welchia firstly checks for Blaster worm and if it is exists continues&amp;nbsp;with Blaster deletion as well as takes care for computer to be immunised&amp;nbsp;for Blaster worm. Also we modeled Malicious high–risk Android App volume&amp;nbsp;growth; Malware evolution; Number of users attacked by Trojan-Ransom&amp;nbsp;malware; Number of users attacked by cryptoransomware; Number of unique&amp;nbsp;users attacked by Trojan-Ransom.AndroidOS.Fusob; and ”Seasonal data”. As&amp;nbsp;the authors in [3] mention: “Even traffic traces used in research papers (e.g.&amp;nbsp;Slammer [4] and Code-red [5]) are not public. From the published papers [4],&amp;nbsp;[5] we are not able to find parameters that can be used in our model”. Many&amp;nbsp;researchers make a hard efforts to describe adequately situation connected to&amp;nbsp;worm propagation [15]–[63].&lt;/p&gt;
