GuLoader, a malware downloader active since 2019, primarily delivers RATs and information stealers. It employs sophisticated anti-analysis techniques, including polymorphic code for dynamic constant construction and complex exception-based control flow obfuscation. The malware has evolved to handle multiple exception types, making tracing its execution flow challenging. GuLoader uses dynamic hashing, encrypted strings, and stack-based string encryption to conceal critical information. It often hosts payloads on trusted cloud services to bypass reputation-based detection. The malware's consistent development and updating of anti-analysis techniques suggest it will remain a significant threat in the future.
