How DNSStager Hides Malware in DNS Queries for Stealthy Penetration Testing

DNSStager is an open‑source tool that encodes, splits, and embeds payloads into DNS AAAA or TXT records, uses a fake DNS server to deliver the chunks, reassembles them on the target, and injects the shellcode directly into memory, enabling covert malware delivery when only DNS traffic is allowed.
