Infoblox has discovered a new malware toolkit called Decoy Dog that uses techniques such as strategic domain aging and DNS query dribbling to avoid detection. This malware is extremely rare, with its DNS signature matching less than 0.0000027% of active domains on the internet. It is delivered through DNS tunneling and has been linked to nation-state actors from China. It has been active for at least a year before its discovery, with three distinct infrastructure configurations identified. It also has strange DNS beaconing behavior, with irregular but infrequent DNS requests.
