DNS Channel Used to Deliver PowerShell Payload in ClickFix Attacks
A new ClickFix variant uses a DNS-based delivery channel: victims are prompted to run nslookup in the Run dialog, querying an attacker-controlled DNS server. The DNS response contains a PowerShell payload that, when executed, downloads a ZIP with a Python runtime and malware scripts, establishes persistence, and installs ModeloRAT. This marks the first known use of DNS for staging and delivering ClickFix payloads, enabling on-the-fly payload updates and blending with normal DNS traffic instead of relying on HTTP.
