The ErrTraffic Malware-as-a-Service framework uses the ClickFix social engineering tactic and EtherHiding blockchain dead-drop resolvers to distribute infostealers and loaders through compromised WordPress sites and fake AI platforms.

Financially motivated actors like Vanilla Tempest are leveraging ClickFix social engineering to deliver modular loaders including BabaDeda, Lorem Ipsum, and Potemkin, ultimately deploying ransomware like Rhysida.

Threat actors can abuse Windows Quality of Service (QoS) policies via PowerShell or WMI to throttle EDR agent outbound bandwidth to near zero, effectively silencing cloud-based telemetry.

Threat actors are utilizing VHDX disk images to deliver Remcos RAT through a multi-stage process involving WMI execution and reflective .NET loading to bypass security controls.
