The analysis of the ShadowSteal malware represents a critical cybersecurity challenge that requires advanced reverse engineering techniques to uncover the true nature and capabilities of this threat. ShadowSteal is designed with advanced capabilities to infiltrate systems, evade detection, and exfiltrate sensitive information while leaving minimal traces. As we'll discover, this malware employs several sophisticated techniques to hide its true functionality, including packing, encryption, and anti-analysis mechanisms.
In this walkthrough, we'll employ a systematic approach to analyzing ShadowSteal, starting with basic static analysis to identify its obfuscation techniques, followed by dynamic analysis to unpack and reveal its true code. We'll then delve deeper to understand its operational mechanics, including how it maintains persistence, gathers information about the system, captures sensitive data, and ultimately removes traces of its existence. Throughout this analysis, we'll use a variety of specialized tools including Detect It Easy (DIE), x64dbg, FLOSS (FireEye Labs Obfuscated String Solver), and other utilities to peel back the layers of this complex threat. We'll examine entropy values, memory allocations, API calls, string obfuscation techniques, and more to build a comprehensive understanding of ShadowSteal's capabilities. By the end of this walkthrough, you'll have gained valuable insights into advanced malware analysis techniques and a deeper understanding of how sophisticated threats operate.
