Cyber espionage group MuddyWater’s or Mercury’s first major campaign was seen as early as 2012. But as things always go in the cybersecurity realm, threat groups, especially those that gain infamy, don’t necessarily just come and go.

Such is MuddyWater’s case in that instead of disappearing, it resurfaces bigger and better each time. PhonyC2—the threat group’s latest addition to its framework—is proof of that. Deep Instinct recently shone the spotlight on PhonyC2’s underbelly by publishing an in-depth investigation on the matter.

The ‘Decoy Dog’ malware toolkit, aimed at enterprises, was uncovered recently by the security analysts at Infoblox by analyzing 70 billion DNS records and traffic that differs from typical online behavior.

Decoy Dog was discovered in early April 2023, and by using domain aging and DNS query dribbling tactics, the Decoy Dog malware assists threat actors in avoiding traditional detection methods. 

This strategy enables them to build a positive reputation with security vendors before transitioning to supporting cybercrime activities.

Decoy Dog has an exceptionally rare and distinct DNS fingerprint compared to the 370 million active domains on the internet, facilitating its identification and tracking.
