This write up is to help the Palo Alto Networks community with detecting a specific PE file.
The sample signature was created on PAN OS Version 7.0.x :
Fill out the appropriate field under the configuration tab
Choose the standard option from the radio button and click on add to create a signature
Since we only have one condition it doesn’t matter if we choose the ‘and’/’or’ condition
To determine a unique string the *NIX utility xxd was used in this case, however any hex editor will work for this purpose. The string was then converted to hex and used in a pattern match to detect the file. In this case the author of the file put what we believe to be their name in the file and that was used as a unique identifier.
Once this custom signature is applied and a web browser is used to attempt to download the file the firewall will either block or alert on detection depending on the action you set.
