前述
在网上有看到许多android安全sdk相关的内容，有重复的也有比较新鲜的内容，这里做一个整体的合集，以及后续又看到一些比较新的东西会一起放在这里。
android内sdk目前可以分为以下几个部分（有一些部分可能会存在一些重合）——设备指纹，root相关，环境检测，模拟器特征，改机软件
设备指纹
1.android_id
google给的app唯一id，存放在/data/system/users/0/settings_ssaid.xml文件中，只有在文件存储位置处修改，设备重刷或设备恢复出厂设置等时候才会被修改。可以用Settings.Global.getString() 、Settings.Secure.getString()、Settings.System.getString()来获取(根据/data/system/users/0/下的文件名字推测可用这些方法获取该目录下一些文件的内容)
2.drmid(设备媒体id)
media drm的设备id，同时和app包名以及签名有关，即不同包名或者不同签名，drmid会不一样，可以视为另外一个android_id，缺点是还和包名有关，注意：极少数机型上获取该id的过程存在崩溃且google也在逐渐的废除该id,可参考：https://developer.android.com/identity/user-data-ids
UUID wideVineUuid = new UUID(-0x121074568629b532L, -0x5c37d8232ae2de13L);
try {
MediaDrm wvDrm = new MediaDrm(wideVineUuid);
byte[] wideVineId = wvDrm.getPropertyByteArray(MediaDrm.PROPERTY_DEVICE_UNIQUE_ID);
return Utils.md5(wideVineId);
} catch (Exception e) {
return null;
}3.gsfiid
gsfiid是Google Service Framework ID，Google服务框架 ID
public static String gsfid() {
Context context = DeviceGlobal.getContext();
Uri uri = Uri.parse("content://com.google.android.gsf.gservices");
if (uri != null) {
try (Cursor cursor = context.getContentResolver().query(uri,
null, null,
new String[]{"android_id"}, null)) {
if (cursor.moveToFirst()) {
return Long.toHexString(Long.parseLong(cursor.getString(1)));
}
} catch (Throwable tr) {
Logger.w(TAG, tr.toString());
}
}
return null;
}4.apk相关
apk安装时间和路径，可以通过getPackageInfo中的firstInstallTime获取，可以作为唯一id和防刷
5.boot_id,oaid,imei,serial number
boot_id可以通过cat /proc/sys/kernel/random/boot_id获取，重启后会更新，是uuid格式字符串格式。
imei是SIM卡相关的信息，谷歌已经删除该属性来保护隐私性
serial number是手机adb devices的一串数字，可以通过getprop ro.serialno获取
oaid是国内android广告标识符，用户可以选择重置和退出广告跟踪。
6.文件哈希
使用stat获取/，/data/，/data/system/vendor/firmware，/system/bin，/vendor/lib，/systen/framework，/system/fonts，或者一些固定app目录的文件名，inode，uid，创建时间，最后修改时间组合等属性组合求hash作为指纹
7.网络相关
这里主要是指机器的ip，mac，网络的类型，这里的信息除了可以做设备指纹之外，也可以用来判断设备的环境等特征。获取方法可以通过ip -a或者ip neigh show命令行执行或者读取/proc/net/arp获取相关信息
root检测
1.path检测
getenv("path") 获取路径，和su或者magisk组合，判断root是否存在
2.属性获取
可以通过以下属性特征来判断设备是不是root了
getprop service.adb.root = "1"
getprop init.svc.adb_root = "running"
getprop ro.secure = "0"
getprop ro.debuggable = "1"
getprop ro.build.tags = "test-keys"3.内存扫描
内存扫描有以下几种方式——1.检测/proc/self/maps 是否存在名为“/memfd:/jit-cache"的段（加载zygisk模块）；2.检测栈空间[stack]的权限是否为"rw-p"；3.检测map表是否存在匿名的且具有可执行属性。
4.selinux上下文检测
cat /proc/self/attr/prev，看文件中的内容是否为"u:r:zygote:s0"，其中r表示进程，zygote表示进程权限
5.常见root应用检测
可以尝试包名检测，遍历/data/data/目录，看有没有一下目录
com.topjohnwu.magisk
eu.chainfire.supersu
com.noshufou.android.su
com.noshufou.android.su.elite
com.koushikdutta.superuser
com.thirdparty.superuser
com.yellowes.su
com.fox2code.mmm
io.github.vvb2060.magisk
com.kingroot.kinguser
com.kingo.root
com.smedialink.oneclickroot
com.zhiqupk.root.global
com.alephzain.framaroot
io.github.huskydg.magisk
me.weishu.kernelsu6.其他
可以尝试访问/data，/system，/etc，查询是否有busybox可以执行——尝试which busybox或者是执行busybox
hook检测
1.frida检测
- 默认端口检测——27042
- 常见路径检测——/data/local/tmp/frida-server
- 检查进程/proc/self/fd/目录，寻找是否存在关键字linjector
- 内存模块扫描——frida-agent，frida-gadge，可以去/proc/self/maps文件下找找字符串
- inlinehook检测frida——查询函数头部是不是0xd61f020058000050
2.Xposed检测
- java.lang.ClassLoader.getSystemClassLoader.loadClass("de.robv.android.xposed.XposedHelpers") ——看xposed是否加载
- 遍历/data/data/目录，寻找有无以下包名
de.robv.android.xposed.installer #Xposed框架
org.meowcat.edxposed.manager #EdXposed框架
com.tsng.hidemyapplist #隐藏应用列表
com.tsng.hidemyroot #隐藏Root
org.lsposed.manager #LSPosed框架
me.weishu.exp #VirtualXposed 太极
top.canyie.dreamland.manager #VirtualXposed 夢境
io.va.exposed #VirtualXposed 夢境
io.va.exposed64 #VirtualXposed 夢境
io.virtualapp #VirtualApp
io.virtualapp.sandvxposed64 #VirtualApp- 检测下列文件或文件路径是否存在
/sbin/.magisk/modules/riru_lsposed
/data/adb/lspd
/sbin/.magisk/modules/zygisk_lsposed
/sbin/.magisk/modules/riru_edxposed
/data/misc/riru/modules/edxp
/data/adb/riru/modules/edxp.prop
/sbin/.magisk/modules/taichi
/data/misc/taichi
/sbin/.magisk/modules/dreamland
/data/misc/riru/modules/dreamland
/data/adb/riru/modules/dreamland
/system/bin/app_process.orig
/system/xposed.prop
/system/framework/XposedBridge.jar
/system/lib/
libxposed_art.so

libxposed_art.so
/system/lib64/
libxposed_art.so
.no_orig
/system/bin/app_process_zposed
/system/framework/ZposedBridge.jar
/system/lib/
libzposed_art.so- artmethod结构体判断，artmethod中access_flags和entry_point_from_jni_在hook过程中会发生更改。
3.调试检测
- 调试端口检测——读取/proc/net/tcp，ida远程调试端口用的是23946端口
- 调试进程名检测——直接ps -a，看是否有android-server或者adb-server
- tracepid检测——读取/proc/self/status，查看tracepid是不是为0
- ptrace检测——因为每个进程只能被一个ptrace检测，所以可以自己启动一个ptrace或者对ptrace检测
- 断电指令检测——检测bkpt指令
- dalvik模式下可以用libdvm.so中dvmDbgIsDebuggerConnected()函数检测，art模式下使用libart.so中gDebuggerActive中
- 可以读取/proc/self/cmdline查看内容是否为zygote

主要是判断系统是x86还是arm，arm64的，通常手机是arm或者arm64架构的，模拟器是x86架构的，这里获取的方式使用seccomp来判断
先安装seccomp架子
void install_check_arch_seccomp() {
struct sock_filter filter[15] = {
BPF_STMT(BPF_LD + BPF_W + BPF_ABS, (uint32_t) offsetof(struct seccomp_data, nr)),
BPF_JUMP(BPF_JMP + BPF_JEQ, __NR_getpid, 0, 12),
BPF_STMT(BPF_LD + BPF_W + BPF_ABS, (uint32_t) offsetof(struct seccomp_data, args[0])),
BPF_JUMP(BPF_JMP + BPF_JEQ, DetectX86Flag, 0, 10),
BPF_STMT(BPF_LD + BPF_W + BPF_ABS, (uint32_t) offsetof(struct seccomp_data, arch)),
BPF_JUMP(BPF_JMP + BPF_JEQ, AUDIT_ARCH_X86_64, 0, 1),
BPF_STMT(BPF_RET + BPF_K, SECCOMP_RET_ERRNO | (864 & SECCOMP_RET_DATA)),
BPF_JUMP(BPF_JMP + BPF_JEQ, AUDIT_ARCH_I386, 0, 1),
BPF_STMT(BPF_RET + BPF_K, SECCOMP_RET_ERRNO | (386 & SECCOMP_RET_DATA)),
BPF_JUMP(BPF_JMP + BPF_JEQ, AUDIT_ARCH_ARM, 0, 1),
BPF_STMT(BPF_RET + BPF_K, SECCOMP_RET_ERRNO | (0xA32 & SECCOMP_RET_DATA)),
BPF_JUMP(BPF_JMP + BPF_JEQ, AUDIT_ARCH_AARCH64, 0, 1),
BPF_STMT(BPF_RET + BPF_K, SECCOMP_RET_ERRNO | (0xA64 & SECCOMP_RET_DATA)),
BPF_STMT(BPF_RET + BPF_K, SECCOMP_RET_ERRNO | (6 & SECCOMP_RET_DATA)),
BPF_STMT(BPF_RET + BPF_K, SECCOMP_RET_ALLOW)
};
struct sock_fprog program = {
.len = (unsigned short) (sizeof(filter) / sizeof(filter[0])),
.filter = filter
};
errno = 0;
if (prctl(PR_SET_NO_NEW_PRIVS, 1, 0, 0, 0)) {
LOG(ERROR) << "prctl(PR_SET_NO_NEW_PRIVS) " << strerror(errno);
}
errno = 0;
if (prctl(PR_SET_SECCOMP, SECCOMP_MODE_FILTER, &program)) {
LOG(ERROR) << "prctl(PR_SET_SECCOMP) " << strerror(errno);
}
}
配合上面的代码 。启动调用getpid， 上面的架子会对getpid函数进行拦截 ，然后架构进行判断
string check_arch_by_seccomp() {
if (get_sdk_level() < __ANDROID_API_N_MR1__){
return "";
}
errno = 0;
syscall(__NR_getpid, DetectX86Flag);
if (errno == 386) {
return "I386设备";
} else if (errno == 864) {
return "X86_64设备";
} else if (errno == 0xA32 || errno == 0xA64) {
return "";
}else if (errno == 0) {
//可能是没有开启seccomp
return "";
}
return ("疑似X86模拟器设备"+ to_string(errno));
}4.硬件模块
- 温度模块——可以通过检测cpu温度记录(在/sys/class/thermal/)来判断模拟器，真机存在，模拟器不存在
int thermal_check() {
DIR *dir_ptr;
int count = 0;
struct dirent *entry;
if ((dir_ptr = opendir("/sys/class/thermal/")) != nullptr) {
while ((entry = readdir(dir_ptr))) {
if (!strcmp(entry->d_name, ".") || !strcmp(entry->d_name, "..")) {
continue;
}
char *tmp = entry->d_name;
if (strstr(tmp, "thermal_zone") != nullptr) {
count++;
}
}
closedir(dir_ptr);
} else {
count = -1;
}
return count;
}- 相机相关——摄像头个数，闪光灯是否存在，模拟器通常只有一个摄像头，没有闪关灯
try {
CameraManager manager = (CameraManager) context.getSystemService(Context.CAMERA_SERVICE);
String[] cameraIds = manager.getCameraIdList();
//摄像头个数
CLog.i("cameraIds -> "+ Arrays.toString(cameraIds));
if(cameraIds.length < CAMERA_MINIMUM_QUANTITY_LIMIT){
items.add(
new ListItemBean(
"当前手机可能是模拟器&云手机",
ListItemBean.RiskLeave.Warn,
"camera size -> "+cameraIds.length
));
}
} catch (Throwable ignored) {
}
- 传感器相关——可以检测传感器数目和种类。和正常的同类型设备相比，模拟器拥有的传感器数目比正常的少许多
try {
//3,检测传感器类型,支持的全部类型传感器
SensorManager sm = (SensorManager) context.getSystemService(SENSOR_SERVICE);
List<Sensor> sensorlist = sm.getSensorList(Sensor.TYPE_ALL);
ArrayList<Integer> sensorTypeS = new ArrayList<>();
for (Sensor sensor : sensorlist) {
//获取传感器类型
int type = sensor.getType();
if (!sensorTypeS.contains(type)) {
//发现一种类型则添加一种类型
sensorTypeS.add(type);
}
}
//小米k40 51个传感器类型
//普通的pix 27个
//华为荣耀20 18个传感器
CLog.e("sensor types size -> " + sensorlist.size());
//我们认为传感器少于20个则认为是风险设备
if (sensorlist.size() < SENSOR_MINIMUM_QUANTITY_LIMIT) {
items.add(new ListItemBean(
"当前手机可能是模拟器&云手机",
ListItemBean.RiskLeave.Warn,
"sensor size -> ("+ sensorlist.size()+") \n" +
"sensor type size -> ("+sensorTypeS.size()+") \n"
//+ "sensor info -> \n"+ Sensorlist //打印全部传感器信息
));
}
传感器名称(有AOSP)——
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
ArrayList<Sensor> aospSensor = new ArrayList<>();
for(Sensor sensor:sensorlist){
if(sensor.getVendor().contains("AOSP")){
aospSensor.add(sensor);
}
}
if (aospSensor.size()>3) {
CLog.e("传感器参数是否异常(生产厂商为AOSP)");
items.add(new ListItemBean(
"当前手机可能是模拟器&云手机",
ListItemBean.RiskLeave.Warn,
aospSensor.size()
+"/"+sensorlist.size()+"传感器参数异常 -> "+ aospSensor
));
}
}
