What is an IST file

IST files mostly belong to Text Editor. IST files have multiple roles depending on where they come from. One common role is as a credit card dump file that holds smart card attack data. This type of file is used in security operations and may be produced by specialized tools from companies like ZOOLANDER X.
Another role is as an InstallShield Template that stores configuration settings. If your IST file comes from IncrediMail, it functions as a settings file. More information is available on the IncrediMail website.
There is also a use as a smart card test script, which is handled by tools such as JCOP Shell to automate testing on smart card systems.

If the content is text-based, open the file with a text editor like Notepad or Notepad++.

Always determine the file’s origin before using or editing it.

IST file format:

If you know the file format, you can also find out how to open or edit the file. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. Knowledge is power - this also applies when dealing with unknown or faulty files. In the following you will find our evaluation of the IST files:
