Unmasking AsyncRAT: Navigating the labyrinth of forks

This ESET research blogpost analyzes the AsyncRAT ecosystem and its many forks, tracing origins, a fork hierarchy, and prominent variants (notably DcRat and VenomRAT) while detailing capabilities such as credential theft, AMSI/ETW bypasses, ransomware plugins, USB spreading, clippers, and other specialized plugins; it also provides identification methods, a comprehensive IoC list, and MITRE ATT&CK mappings to help defenders detect and attribute these widely reused open-source RAT variants.
