小白爆破租车管理系统
小白第一次发帖，有讲的不清楚的地方还请大家批评指正呀！！有点小慌！{:301_975:}软件是无壳的，适合萌新练手，大佬无视吧！{:301_997:}软件打开 按注册 提示 注册码错误
直接载入od
到解码段 00401000
中文搜索ascii 注册码错误
找到 关键跳 004E487E /74 3F je short Rent.004E48BF 把je改为jmp
F8单步 到 004E48F1 /0F84 30010000 je Rent.004E4A27直接nop填充
复制到可执行文件 保存修改 ok对比看看
需要练手的小白可以下载练练，大佬就直接飘过吧{:301_998:}

解码段 00401000怎么来的，？楼主解码段 00401000？
ctrl+g 然后输入00401000 追注册码更有意思，继续加油 还有这种操作 厉害了 感谢分享。学习了 这个够叼啊。`1 谢谢分享,收藏学习!{:1_893:} 嗯~~~~~要是把租车系统破解了就妙了 哈哈，原来破解这样有意思 感谢分享。 牛{:1_893:}，学习了
