特点如下:

1) 试用次数记录在 0 号物理驱动器第 62 扇区,即使重装系统,也不会被覆盖
2) 启动进程 A.exe,伪装进程 B.exe,实际进程 C.dat, B 和 C 同名
A ---> 读取 C,在内存中解密[ C 其实是个加UPX壳的 exe]
   ---> 创建 B,挂起,得到B的主线程环境
   |
   |_> 在 B 的空间里,写入 C,随后,修改 B 的主线程环境,使得 EIP 为 C 的入口
|_> 启动 B 的主线程(实际上是运行 C)

总结陈述:

1) rsRSWBSW.exe :
加载 RSWBSW.dat,解密; 启动 RSWBSW.exe 进程并挂起;
将解密后的 RSWBSW.dat(实质是加 UPX 壳的 exe 文件)写入 RSWBSW.exe 进程空间,替
换掉 RSWBSW.exe 的内容,随后,启动替换后的 RSWBSW.exe 主线程

2) RSWBSW.dat :
被解密后,可以从 rsRSWBSW.exe 进程中复制出来,另存为一个 exe文件,比如 ppx.exe,
随后,UPX脱壳,然后修改指令,爆破

3) RSWBSW.exe :
启动 rsRSWBSW.exe,完成 1) 2) 动作,随后自己退出

4) 试用次数写在 0号物理驱动器第 62 扇区[ 512字节/扇区 x 62 = 7C00h ]偏移 100h
处,格式是 52 53 57 42 00 1C => R S W B . .
