Researchers and security teams have detected a technique that transforms the DNS domain name system into an unconventional means of storing files and data. In general terms, this technique exploits the ability of DNS records to carry information and can be leveraged by malicious actors to hide fragments of code or data in DNS responses without needing to create visible files on victims' systems

The malicious use of DNS as a data channel generates significant risks, including evasion of detection by traditional tools, covert persistence, creation of command and control channels, and stealthy exfiltration of sensitive information. These tactics exploit a blind spot in many infrastructures where DNS traffic is considered legitimate and therefore receives less inspection

Faced with this threat, defensive measures should focus on visibility and advanced detection. Applicable general recommendations include continuous monitoring of DNS traffic, correlation of events with threat intelligence, analysis of anomalies in query volumes and patterns, limiting the size and type of allowed records, and deploying authentication and security mechanisms in DNS such as DNSSEC. Likewise, it is key to integrate EDR and SIEM solutions and leverage AI-based analytics to reduce false positives and detect suspicious patterns at scale
