Hackers are hiding malware inside DNS records, allowing malicious code to bypass security defenses that typically monitor web and email traffic. DomainTools researchers discovered the technique being used to host Joke Screenmate malware, with binary files converted to hexadecimal format and broken into chunks stored in TXT records across subdomains of whitetreecollective[.]com.

Attackers retrieve the chunks through DNS requests and reassemble them into executable malware. The method exploits a blind spot in security monitoring, as DNS traffic often goes unscrutinized compared to other network activity.
