传送门：全球知名移动间谍软件FlexiSpy的分析(part1)
0x00 前言
这是FlexiSpy分析的第二部分。反病毒的同行注意了，新的IOC和我的jeb数据库文件在本文底部。这个应用很大，因此我需要将它分割为多个部分。在主apk文件中有几个组件。我们先看下assets（注意这些zip文件是apk和dex文件）。

ben@bens-MacBook:~/Downloads/bin/5002_2.24.3_green.APK.out/assets/product$0x01 方法
监控软件有3个版本。这个非常棒，因为它包含了完整的代码注释。
l 泄漏的源码版本是1.00.1。虽然有文档，但是它只有2.x版本以下的一小部分功能。
l 2.24.3 APK文件：这是编译好的代码，不包含任何注释。这比泄漏的源代码版本新。有更多功能。有混淆，且有大量的额外的Modules/assets.
l 2.25.1 APK：编译代码。没有注释。转储中最新版本。我们看出来和2.24.3的区别
有两个Windows可执行程序和一个mac可执行文件。我还没有看它们。
计划从应用的入口点开始（当用户点击图标时发生），并且检查intent接受器。
0x02 AndroidManifest.xml信息
在这有一些有趣的东西。首先包的名字是com.android.systemupdate。这个可能是命名欺骗用户，认为这个应用是一个官方的安卓应用。

用户安装应用程序时运行的第一个activity是com.phoenix.client.PrerequisitesSetupActivity。让我们看下它的功能。
对于大部分的android activities，onCreate方法通常首先运行。在一个GUI初始化后，应用检查手机是否root。
public void onCreate(Bundle arg6) {
super.onCreate(arg6); // ignore
this.setContentView(2130903047); // ignore
StrictMode.setThreadPolicy(new StrictMode$ThreadPolicy$Builder().permitAll().build());
this.o_Button = this.findViewById(2131165209); // ignore
this.o_Button2 = this.findViewById(2131165210); // ignore
this.o_TextView = this.findViewById(2131165207); // ignore
this.k = this.findViewById(2131165208); // ignore
this.k.setVisibility(4); // ignore
this.o_TextView.setText(String.format(this.getString(2130968605), cz.m_superUserCheck(((Context)this)), this.getString(2130968601))); // can return SuperSU or Superuser0x04 root检查 cz.m_superUserCheck
实际的root检查如下。检查是否安装了4个root包中的任何一个。来表明设备是否被root。注意这是代码库中众多root/package检查中的第一个。
public static SuBinaryProvider d(Context arg1) {
SuBinaryProvider v0;
if(e.m_LooksForInstalledPackages(arg1, "com.noshufou.android.su")) {
v0 = SuBinaryProvider.NOSHUFOU_SUPERUSER;
}
else if(e.m_LooksForInstalledPackages(arg1, "eu.chainfire.supersu")) {
v0 = SuBinaryProvider.CHAINFIRE_SUPERSU;
}
else if(e.m_LooksForInstalledPackages(arg1, "com.m0narx.su")) {
v0 = SuBinaryProvider.M0NARX_SUPERUSER;
}
else if(e.m_LooksForInstalledPackages(arg1, "com.koushikdutta.superuser")) {
v0 = SuBinaryProvider.KOUSHIKDUTTA_SUPERUSER;
}
else {
v0 = SuBinaryProvider.CHAINFIRE_SUPERSU;
}
return v0;根据是否检测到root包，设置值为SuperUser或者SuperSU。
public static String m_superUserCheck(Context arg3) {
SuBinaryProvider SuCheck = cz.ChecksforSuPackages(arg3); // checks for 4 packages
String str_returnValSuperSu = "SuperSU"; // default return val
if(SuCheck == SuBinaryProvider.CHAINFIRE_SUPERSU) {
str_returnValSuperSu = "SuperSU";
}
else {
if(SuCheck != SuBinaryProvider.NOSHUFOU_SUPERUSER && SuCheck != SuBinaryProvider.KOUSHIKDUTTA_SUPERUSER && SuCheck != SuBinaryProvider.M0NARX_SUPERUSER) {
return str_returnValSuperSu;
}
str_returnValSuperSu = "Superuser";
}
return str_returnValSuperSu; // can return SuperSU or Superuser0x05 回到onCreate
在root检查后，应用检测SD卡中的一个文件。这个可能是检查应用程序是否之前安装过。根据ac.txt文件是否存在，两种执行将发生：一个启动AutoInstallerActivity，另一个启动CoreService。
this.o_TextView.setText(String.format(this.getString(2130968605), cz.m_superUserCheck(((Context)this)), this.getString(2130968601))); // can return SuperSU or Superuser
this.o_Button.setOnClickListener(new cp(this));
this.o_Button2.setOnClickListener(new cq(this));
if(cz.m_acTextCHeck()) { // checks for ac.txt value on SDcard
Intent o_intentObj = new Intent(((Context)this), AutoInstallerActivity.class); // if the txt file IS present
o_intentObj.setFlags(335544320);
this.startActivity(o_intentObj); // starts theAutoInstallerActivity class
this.finish();
}
else {
this.g = new SetupFlagsManager(o.a(this.getApplicationContext())); // if the txt file is NOT present
this.f = ak.a(((Context)this));
if(this.c == null) {
this.bindService(new Intent(((Context)this), CoreService.class), this.l, 1);
}
else {
this.b();
}
}不管执行什么路径，coreService都会启动。AutoInstallerActivity有一些安装步骤，写一些日志文件，创建一些自定义安装对象和启动CoreService类。此时应用等待用户交互。细节如下。
0x06 com.phoenix.client.receiver.CommonReceiver
Receivers监听android上来的intents。当屏幕解锁，手机重启或者新的SMS消息到达时代码得到响应。
<intent-filter android:priority="2147483647">
<action android:name="android.intent.action.USER_PRESENT" />
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
<action android:name="android.intent.action.PHONE_STATE" />
<action android:name="com.htc.intent.action.QUICKBOOT_POWERON" />
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>0x07 接收SMS
当接收SMS被检测到。应用在SMS消息中查找指定值<*#。这好像是发送给受害者的一个指定的命令控制值。
while(o_Iterator.hasNext()) {
str_intentAction = o_Iterator.next().getMessageBody();
if(str_intentAction != null && (str_intentAction.trim().startsWith("<*#"))) { // look for a "special value" in sms
i_specialCommandFound = 1;
continue;
}
i_specialCommandFound = 0;在泄漏的源代码文件中的交叉引用中1.00.1/_build/source/daemon_remote_command_manager/src/com/vvt/remotecommandmanager/SmsCommandPattern.java表明SMS消息中的这个<**是用于远程命令。1.00.1版本的命令如下。

监控软件监听各种intent表明用户在使用手机：如果屏幕解锁，设备开机等。
label_65: // this is if NO sms is detected
if((str_intentAction.equals("android.intent.action.BOOT_COMPLETED")) || (str_intentAction.equals("android.intent.action.QUICKBOOT_POWERON")) || (str_intentAction.equals("com.htc.intent.action.QUICKBOOT_POWERON"))) {
com.fx.daemon.b.m_relatedToShellCmds(o.m_getDataPath(arg6), "fx.log");
StrictMode.setThreadPolicy(new StrictMode$ThreadPolicy$Builder().permitNetwork().build());
if(CommonReceiver.c()) {
return;
}
if(!CommonReceiver.f_bool_maindZip()) {
return;
}
AppStartUpHandler.a(dataPath, AppStartUpHandler$AppStartUpMethod.BOOT_COMPLETED);
ak.m_generatesSameObj(arg6);
ak.b(arg6);
return;
}第一个条件
在接收到intent后，我们看到if语句
if(CommonReceiver.b_returnTrueIfDebugMode()) {
return;
}代码只检查是否有DEBUG_IS_FULL_MODE，命令将发送给受害者设备。
第二个条件
第二个if语句如下。它执行另一个系列root检查和检查maind.zip文件是否存在。
if(!CommonReceiver.RootAndMainZipCheck()) { // if not rooted and a zip doesnt exist exit
return;
}
F_bool_maindZip方法与位于/assets/production/文件夹中的maind.zip有关。
private static boolean RootAndMainZipCheck() {
boolean returnVal = true;
String str_maindZipPath = o.str_FilePathGetter(b.str_dataMiscAdn, "maind.zip");
if((ShellUtil.m_bool_MultipleRootcheck()) && (ShellUtil.m_ChecksForFIle(str_maindZipPath))) {
returnVal = false;
}
return returnVal; // return true if rooted AND maind.zip is found
}这个方法执行一系列root检查。它查看设备的Build Tags值是否存在test-keys，检查SuperUser.APK应用，su二进制的位置，环境路径检查和尝试调用一个shell。代码如下：
public static boolean m_bool_Rootcheck() {
boolean bool_returnVal = false;
if(ShellUtil.bool_debug) {
Log.v("ShellUtil", "isDeviceRooted # START ...");
}
String str_buildPropTags = Build.TAGS;
boolean str_TestKeys = str_buildPropTags == null || !str_buildPropTags.contains("test-keys") ? false : true;
if(ShellUtil.bool_debug) {
Log.v("ShellUtil", "checkRootMethod1 # isDeviceRooted ? : " + str_TestKeys);
}
if((str_TestKeys) || (ShellUtil.f_bool_checksForSUperSuAPK()) || (ShellUtil.m_bool_SuCheck()) || (ShellUtil.m_boolEnvPathCheck()) || (ShellUtil.m_boolTryToExecShell())) {
bool_returnVal = true;
}
if(ShellUtil.bool_debug) {
Log.v("ShellUtil", "isDeviceRooted # isDeviceRooted ? : " + bool_returnVal);
}
if(ShellUtil.bool_debug) {
Log.v("ShellUtil", "isDeviceRooted # EXIT ...");
}
return bool_returnVal通过下面的方法执行maind.zip检查
public static boolean m_ChecksForFIle(String arg7) {
boolean b_returnVal = true;
try {
c_RelatedToFxExecLib v2 = c_RelatedToFxExecLib.b();
String v3 = v2.a(String.format("%s "%s"", "/system/bin/ls", arg7));
v2.d();
if(v3.contains("No such file or directory")) {
return false;
}
}
catch(CannotGetRootShellException v0_1) {
b_returnVal = new File(arg7).exists();
}
return b_returnVal;回到reveiver
在第二个if语句后有如下的代码。
AppStartUpHandler.a(dataPath, AppStartUpHandler$AppStartUpMethod.BOOT_COMPLETED);
ak.m_generatesSameObj(arg6);
ak.startCoreService(arg6); // starts the "engine"
return;非常简单。Ak.startCoreService(arg6)方法只再次启动coreService。记住这是从文章开头的onCreate方法开始的。
0x09 下集预告
下一步，我将看下CoreService和其他的intent receiver com.vvt.callhandler.phonestate.OutgoingCallReceiver，其监听去电。
0x0A 新的IOCs
对于AV行业来说，在VirusTotal中可以查找到更多的IOC。
