docs(huya): 模拟器存活闪退诊断报告与 Frida 探测脚本证据
- 诊断报告: attach 主进程静默退出/EGL 崩溃, 仅约 4s 窗口可抓帧 - scripts: attach/spawn/hook/emu 系列 Frida 脚本与抓帧/验证工具 - evidence: identity/reqchain/frame/inputbuf/magic_buf/propedge 抓取样本, emu_* 存活对比, diag_* 策略实验, baseline 裸测基准

"""模拟器 hdid v8: spawn + 三件套 + 内存扫描 32hex (App 启动即扫, 无需触发登录).
|
||||
|
||||
时序(成功验证): spawn → bypass×2(挂起) → resume → 立即 patch_guard → 主JS:
|
||||
1. 轮询 hook setSafeDeviceId/getHdid/createWupDeviceInfo (保险)
|
||||
2. 轮询: mod-base 出现后 3s, 扫描进程内存找 [0-9a-f]{32} ASCII 字符串并去重
|
||||
3. SSL_write 抓 hypasswordLogin (万一触发登录)
