Let's drill deeper now and take a look inside one of these files and I'm going to pick " (Business and Industry).txt" and as best I can make it, is a Thai fashion site. Because it's relevant to the story and especially relevant to people who find their data in this breach via an HIBP search, I'm going to list the two sets of files in their entirety via the following Gists: This is where the "more than 23,000 hacked databases" headlines come from as this is how many files are in the archive. rar files giving a grand total of 23,618 files. rar files in it whilst the second has a further 8,949. More on that shortly, let's start with what's in there and we're looking at a zip file named "Cit0day.in_special_for_xss.is.zip" that's 13GB when compressed:Ī couple of folders down are two more folders named "Cit0day " and "Cit0day Prem "Īnd then this is where it gets interesting: The first folder has 14,669. The hard bit for me is figuring out whether it's pwn-worthy enough to justify loading it into Have I Been Pwned (HIBP) or if it's just more noise that ultimately doesn't really help people make informed decisions about their security posture.

In File Explorer under View, in the Show/hide group, select the File name extensions check box.īelow is a list of common Windows file name extensions and formats.It's increasingly hard to know what to do with data like that from Cit0Day.

In the search box on the taskbar, type file explorer, and in the search results, select File Explorer. If you don’t see file name extensions when you view files in File Explorer: To learn more about how to change which program will open a file, read Change default programs in Windows 10. You can change a file name extension, but that won't convert the file to another format or change anything else about it except the file name. Most file name extensions are compatible with more than one program that you have installed. For example, the docx extension tells your computer that Microsoft Word can open the file and to display a Word icon when you view it in File Explorer. In expenses.xlsx, for example, the first part of the file name is expenses and the extension is xlsx.Įxtensions tell your computer which application created or can open the file and which icon to use for the file. Windows file names have two parts separated by a period: first, the file name, and second, a three- or four-character extension that defines the file type.
