ParaBytes ReVerSeMe2 逆向分析过程
Written By lnn1123 06.4.10
最新老受打击,朋友一个个混的不错,感觉自己不行啊,没自信啊,找了一个软柿子来搞,发泄一下.由于本人技术有限,文章很可能
存在错误,所以如有发现请告诉我,最后谢谢你看此文.
看一个这个ReVerseMe要求,如图(1)
图(1)
意思:要你自己添加2个edit框,一个button,然后添加代码验证输入的内容是否是内定的内容
思路: 要求是添加2个edit,一个button应该想到用CreateWindowEx函数来创建,然后才添加验证输入的代码
添加代码前一定先查看区块缝隙,如图(2)
图(2)
400-33a=C6 由于代码可能多余这么大,所以应该添加一个区块,添加区块后,因为要添加验证部分功能,所以还得添加输入表部分
需要的函数 virtulealloc,GetWindowText,一切用lordpe搞定,搞定后如图(3)
图(3)
现在到分析代码的时候了,为wndpro修改跳转添加代码用

这样修改后就完成了这个ReVerseME
修改后的ReVerseMe
Written By lnn1123 06.4.10
最新老受打击,朋友一个个混的不错,感觉自己不行啊,没自信啊,找了一个软柿子来搞,发泄一下.由于本人技术有限,文章很可能
存在错误,所以如有发现请告诉我,最后谢谢你看此文.
看一个这个ReVerseMe要求,如图(1)
图(1)
意思:要你自己添加2个edit框,一个button,然后添加代码验证输入的内容是否是内定的内容
思路: 要求是添加2个edit,一个button应该想到用CreateWindowEx函数来创建,然后才添加验证输入的代码
添加代码前一定先查看区块缝隙,如图(2)
图(2)
400-33a=C6 由于代码可能多余这么大,所以应该添加一个区块,添加区块后,因为要添加验证部分功能,所以还得添加输入表部分
需要的函数 virtulealloc,GetWindowText,一切用lordpe搞定,搞定后如图(3)
图(3)
现在到分析代码的时候了,为wndpro修改跳转添加代码用
