Description

AsyncRAT, an open-source remote access trojan, has evolved into a sprawling network of forks and variants since its 2019 release. The article explores its origins, tracing influence from Quasar RAT, and maps out the relationships among various forks. DcRat and VenomRAT emerge as the most widely deployed variants, offering enhanced features and capabilities. Lesser-known forks like NonEuclid RAT, JasonRAT, and XieBroRAT introduce unique plugins and functionalities. The proliferation of AsyncRAT forks highlights the risks associated with open-source malware frameworks, lowering barriers for cybercriminals and contributing to an increasingly complex threat landscape.
