Clop Ransomware in Action: A Comprehensive Analysis of Its Multi-Stage Tactics

Abstract

Recently, Clop ransomware attacks targeting non-IT fields such as distribution, logistics, and manufacturing have been rapidly increasing. These advanced attacks are particularly concentrated on Active Directory (AD) servers, causing significant operational and financial disruption to the affected organizations. In this study, the multi-step behavior of Clop ransomware was deeply investigated to decipher the sequential techniques and strategies of attackers. One of the key insights uncovered is the vulnerability in AD administrator accounts, which are often used as a primary point of exploitation. This study aims to provide a comprehensive analysis that enables organizations to develop a deeper understanding of the multifaceted threats posed by Clop ransomware and to build more strategic and robust defenses against them.
