奥拉星Flash端逆向(1)

ffdec反编译version目录树:

1.1 通过http://aola.100bt.com/play/start~1.xml 中v=""拿到version版本号

1.2 下载并使用ffdec反编译http://aola.100bt.com/play/versiondata~{version}.swf

1.3 export DefineBinaryData → bin后缀修改为xml

ffdec命令调用批处理swf解包流程

2.1 源项目地址 GitHub - jindrapetrik/jpexs-decompiler: JPEXS Free Flash Decompiler

2.2 使用java -jar ffdec.jar --help 查看支持的命令

2.3 此处使用 java -jar ffdec.jar -export binaryData <输出目录> <swf文件> -format xml
