Infoblox Uncovers DNS Malware Toolkit & Urges Companies to Block Malicious Domains

SANTA CLARA, Calif., April 20, 2023 /PRNewswire/ — Infoblox Inc. the company that delivers a simplified, cloud- enabled networking and security platform for improved performance and protection, today published a threat report blog on a remote access trojan (RAT) toolkit with DNS command and control (C2). The toolkit created an anomalous DNS signature observed in enterprise networks in the U.S., Europe, South America, and Asia across technology, healthcare, energy, financial and other sectors. Some of these communications go to a controller in Russia.

A technical analysis of Infoblox’s findings is here.

“Decoy Dog is a stark reminder of the importance of having a strong, protective DNS strategy,” said Renée Burton, Senior Director of Threat Intelligence for Infoblox. “Infoblox is focused on detecting threats in DNS, disrupting attacks before they start, and allowing customers to focus on their own business.”
