Zararlı Yazılımların Karekterislik Analizi: Cryptowall Fidye Yazılım Analizi

Abstract

CryptoWalls ranks first among the Ransomware in terms of its design, objectives, and damages. Cybercriminals use CryptoWalls in a wide range of applications, from cross-country cyberterrorism to demanding ransom from an ordinary Internet user. Despite all the measures taken, an effective protection against CryptoWalls has still not been developed. This motivates cyber criminals, and new versions of updated CryptoWalls are released every day, becoming a more difficult problem to be solved. Current research studies discuss the general characteristics and consequences of CryptoWalls. How do CryptoWalls work? How the CryptoWall detection and technical analysis are done? Detailed studies on the answers to these questions will contribute to solving this problem. This study discusses detailed analysis of CryptoWall detection on a real victim's computer, targeted by the CryptoWall attack of cybercriminals. The study is of importance since it addresses how the CryptoWall attack infiltrates the target system, shows the analysis steps of its characteristic actions, and identifies the originating company of the CryptoWall malware.
