- 输入图定案: 库内零硬件文件读, 种子=ANDROID_ID+服务端hydeviceid_config+MID, 属性层无关(X1/X2) - 真机全段解密 dump(phone_dump_hydev_full) + merge_decrypted 合入原文件 → unidbg 可直接加载 - unidbg(JDK21+patch) harness: JNI 桩(SharedPreferences日志化/Settings.Secure/NativeBridge) 金测试: androidId 加密态与 getGUID 全部与真机一致 - 遗留: NativeBridge.b(100) 原生归属库未定(非hydeviceid/udb/device-util), 当前桩替顶 - 修正结论: '单机不可铸造'判断错误, GUID=b(100)=f(androidId密, config, MID) 输入全可控

"""真机 FULL dump libhydeviceid.so (r-x + r-- + rw- 全部段, 含解密后的 .data/.got).
|
|
|
|
上次 phone_dump_hydev 只抓 r-- (代码+rodata), .data/.got/.bss 全零 —— unidbg 需要
|
|
完整解密镜像(密钥/GOT 都在 .data). 本脚本抓到全部可读内存.
|
|
|
|
用法:
