SckTool sends text and binary data to a server for testing and debugging. Originally written while analyzing the MyDoom A/B/C backdoors and useful for plenty of analyses since.
| Feature | Detail |
|---|---|
| Multiple clipboards | The current send-buffer contents can be swapped down to two other text pads for quickly cycling between payloads. Implemented as the 1 and 2 buttons next to the port textbox. |
| Data buffer expansion | The send buffer supports the [DATA] tag, which expands to a predefined length of bytes. Expansion runs either on send (with the checkbox option) or immediately in the textbox via the now button. Useful when a payload needs an exact byte count. |
| Binary data | The send buffer supports %xx hex character encoding for non-printable characters. The % escape character can be customized for more readable output (e.g. _ or .). |
| Data file sending | Drag and drop a file onto the send-file textbox and click Load file to load it into memory. You can optionally reset the send-buffer size to a specific value if data packets must match a target size. |
| %TEMP% file listing | If exploring file-upload features of backdoors, they often create uploads in %TEMP%. The file listbox can be manually refreshed to watch for new files and shows their size on selection. |
