# **0x01 介绍** #

Adobe(R) Malware Classifier 是一款win32恶意软件分析工具，本身采用python脚本编写。支持dll,exe等windos程序。

其中最主要的是基于行为检测和特征归类就行分析，本引擎对130000个恶意程序和16000个正常软件进行分析比对，归纳。

实现精确匹配。

[官方地址][Link 1]

其中代表含义如下：

\# 0 = CLEAN //安全程序  
\# 1 = DIRTY //恶意程序  
\# UNKNOWN //未知程序。

采用4种算法进行分析。

![Center 1][]

FP 假阳性 将正常文件误判为恶意软件

TN 真阴性 将正常文件判定为正常文件

TP 真阳性 将恶意软件判定为恶意软件

FN 假阴性 将恶意软件判定为正常文件
