📢 [EN] Channel Activity Suspended (Indefinitely)
⚠️ Due to unforeseen legal circumstances, our channel owner — and lead developer of the .NET deobfuscation tools — is temporarily stepping away from all public activities.

Reason:
- Ongoing legal investigation tied to alleged "unauthorized software analysis"
- Restrictions imposed by local law enforcement
- No timeline for return

BUT — our tooling remains alive:
✅ We still provide private sales of all our deobfuscators
✅ Full support for VMProtect, ConfuserEx, Babel,
Agile.NET, Eazfuscator, DNGuard, and more
✅ Business as usual — just no public channel updates for now

---

📢 [中文] 频道暂停更新(期限未定)
⚠️ 由于不可预期的法律原因,我们的频道负责人 —— 同时也是核心解混淆工具的开发者 —— 暂时中止所有公开活动。

原因如下:
- 正在接受“非法软件分析活动”的调查
- 本地执法机构限制其网络行为
- 恢复时间暂未可知

但工具服务仍在继续:
✅ 所有解混淆工具仍可私下购买
✅ 完整支持 VMProtect, ConfuserEx、Babel、Agile.NET、Eazfuscator、DNGuard 等方案
✅ 售后与支持一切照旧,仅暂停公开发布
