ClickFix Variants, Deepfake Scams and ViewState Attacks Feature in 2025 Threat Trends

Summary
Huntress reviews 2025 threat trends, including cross-platform ClickFix lures, deepfake-enabled social engineering and attacks exploiting exposed ASP.NET machine keys for ViewState code injection.
Key points
- ClickFix lures victims into pasting attacker-supplied commands; variants target macOS and Linux, while FileFix uses Windows File Explorer.
- A reported fake AnyDesk installer attack used a Cloudflare Turnstile lure and an MSI disguised as a PDF to deliver MetaStealer, an infostealer that harvests credentials and files.
- Huntress recommends restricting Windows shortcuts and clipboard use to help mitigate ClickFix attacks.
- Deepfake video in a Zoom meeting reportedly persuaded an employee at a Web3 organization to download a malicious extension; the article also describes deepfakes used in fraud and job-related infiltration.
- The article recommends preparing for deepfake impersonation with response plans, physical validation and strict account-reset controls.
- Microsoft identified more than 3,000 publicly disclosed ASP.NET machine keys that could enable ViewState code injection if used on servers.
- The article cites ViewState attacks involving hardcoded keys in Gladinet CentreStack and Triofox, and a zero-day affecting Sitecore deployments (CVE-2025-53690).
Article Details
- Event Type
- Huntress reported 2025 cyber threat trends involving ClickFix-style social engineering, deepfake-enabled attacks, and exploitation of ASP.NET ViewState weaknesses.
- Impact
- Reported attacks have led to delivery of MetaStealer to steal credentials and files, employee compromise through deepfake impersonation, financial fraud, and arbitrary code execution through ViewState deserialization. The article cites a $25 million fraud loss at Arup and exploitation affecting Gladinet CentreStack/Triofox and Sitecore deployments.
