In the ever-evolving landscape of cybersecurity threats, a recent discovery has sent shockwaves through the industry. Meet "Decoy Dog," a formidable malware that has taken the foundation of the Pupy RAT, an open-source remote access trojan, and transformed it into a sophisticated and highly potent threat. Today, we delve into the depths of this malicious entity, revealing it’s never-before-seen capabilities that have left experts astonished.
The origins of Decoy Dog remain unclear as yet, but it's suspected to be operated by a handful of nation-state hackers, who employ distinct tactics but respond to inbound requests that match the structure of client communication. Decoy Dog makes use of the domain name system (DNS) to perform command-and-control (C2). An endpoint that's compromised by the malware communicates with, and receives instructions from, a controller (i.e., a server) via DNS queries and IP address responses.
Java Code Execution and Sophisticated Communication:
The malware has the ability to execute arbitrary Java code on client systems, adding an extra layer of complexity to its attacks. Furthermore, the malware employs a mechanism akin to a traditional DNS domain generation algorithm (DGA) to connect with emergency controllers. This innovative communication technique involves Decoy Dog domains designed to respond to replayed DNS queries from compromised clients, making it even more challenging to detect and combat. According to Dr. Burton, head of threat intelligence at Infoblox, Decoy Dog outperforms its predecessor Pupy, with a command to redirect communication from the current controller to an alternative one, detected through statistical analysis of DNS queries.

Decoy Dog Threat Actors' Swift Adjustments and Ongoing Threat:
The threat actors behind the operation are said to have made swift adjustments to their attack infrastructure in response to the earlier disclosures, taking down some of the DNS nameservers as well as registering new replacement domains to establish remote persistence. The first known deployment of Decoy Dog dates back to late-March or early-April 2022, following which three other clusters were detected as under the control of different controllers.
