Download the Senf tool - SenfNet.zip

A pop up box will appear to “Open or Save”.

Make sure you save to the “Desktop”.

Right click on SenfNet .zip file, and select “Extract Here” or “Extract All” (depending on what extraction program you have).

Continue through the extraction wizard to unzip the files.

Double click on the SenfNet.exe icon.

Click on the “Browse” button to chose the scan path – you’ll want to scan your entire hard drive, which in this case is C:\.  To make the output easier to read, change the file extension on the log file name to .csv.

When you’re satisfied with your choices, click the “Scan” button in the bottom right-hand corner.  The scans can take quite some time to complete, as the program will be scanning every file on the system.

When the scan is complete, you can double click on the results in the lower window to view excerpts of the data that was flagged as possible sensitive information.

 

Suppose the Senf program returned “C:\Program Files\Purchase Info\senfexample.txt” as a file that might contain sensitive information and you’d like to take a closer look at the file.  The easiest way to navigate to that location would be to right click on Start and select “Explore”.

On the left side of the screen, you’ll see a listing of the contents of the computer, much like this –

In our case, we’re looking for a folder that’s in the C:\ drive, so we need to expand the view of the drive by clicking the plus sign to the left of it.

Now we need to open up the “Program Files” folder in the same way – click the plus sign to the left of the folder.

To open the "Purchase Info" folder, click on the corresponding folder.

In the right pane, you can see the “senfexample.txt” – just double click the file and you can check it for SSNs and credit card numbers.
