Windows Defender detects v0.8.0 Windows binary as Trojan:Win32/Bearfoos.A!ml #41

Open

Description

@TomcatSu

Summary

Windows Defender quarantined the AgentDock v0.8.0 Windows x64 core binary during installation.

Environment

Detection

  • Detection name: Trojan:Win32/Bearfoos.A!ml
  • Affected file: agentdock.exe
  • Result: Windows Defender quarantined the core binary, so the local service could not remain running.
  • SmartScreen also displayed an unrecognized-app warning when launching the installer downloaded through a browser.

Verification

The installer SHA-256 matched the checksum published by the official release:

1C3547244A23281932004AC3513F9695E47D7AD0ABEADF77FB778B7C49C6B631

Could you please confirm whether this is a known false positive, whether the release artifact is expected to be signed, and whether a corrected Windows build or updated checksum is available?

No credentials or private configuration data are included in this report.

    补充中文说明:

    在 Windows 11 x64 上,通过官方 Windows 图形化安装程序安装 AgentDock v0.8.0 时,Windows Defender 将核心文件 agentdock.exe 检测为 Trojan:Win32/Bearfoos.A!ml 并隔离,导致本地服务无法持续运行。

    安装程序 SHA-256 已与官方发布的校验值一致:

    1C3547244A23281932004AC3513F9695E47D7AD0ABEADF77FB778B7C49C6B631

    同时,使用浏览器下载的安装程序还触发了 SmartScreen“无法识别的应用程序”提示。请确认这是否为误报、发布文件是否应带有数字签名,以及是否有修正版或新的校验值。

    补充测试结果(v0.8.1):

    在官方 v0.8.1 Windows x64 安装程序的 SHA-256 与官方校验值一致后进行安装,Windows Defender 仍然检测并隔离 agentdock.exe,检测名称为 Trojan:Win32/Bearfoos.A!ml。

    结果:

    • 安装目录可以建立;
    • agentdock-tray.exe 保留;
    • agentdock.exe 被 Defender 移除;
    • 本地 8765 端口没有监听;
    • http://127.0.0.1:8765/healthz 无法连接;
    • AgentDock 本地服务无法持续运行。

    补充以上测试结果供参考。若方便的话,也想请教 v0.8.1 Windows 核心二进制目前是否有数字签名,以及对于 Defender 的这项检测是否已有建议的处理方式。感谢维护与协助。

    现在的版本使用了数字签名,但当前证书属于自签名/非公开受信 CA 信任证书,因此 SmartScreen 仍可能警告;SHA-256 与官方发布文件一致;Defender 的 !ml 检测正在按疑似误报处理。建议先在Defender信任还原,等待后续版本更新受信任签名。
