Many people use the Snipping Tool that comes standard with Windows. It allows you to easily take screenshots and also crop them. But it is precisely with the latter that you have to be careful, because you can easily leak sensitive information.
There are several Windows programs for taking screenshots (screenshots). And of course you can take a screenshot by the key combination Shift + Print Screen to use it afterwards Ctrl + v pasted into the Paint program. Want to take part of a screenshot, many use it Snipping Tool which is standard in Windows. Conveniently, you can also crop parts of the screenshot with the Snipping Tool. Unfortunately, a problem has now been discovered when saving screenshots.
Snipping tool vulnerable in Windows
The problem arises when you crop certain things from a screenshot, but this cropped information still ‘remains’ in the saved file. That only happens if you save the trimmed file with the same name as the original. In this case, the file size stays the same instead of getting smaller, even after you cut and delete the information. So after saving the ‘new’ file with the same name, the data from the original image remains in the file, after which it can be easily seen with the help of a hex editor. So if you cut away sensitive information such as usernames and passwords, they can be retrieved. Incidentally, this vulnerability does not occur with the previously mentioned Paint program. We expect Microsoft to release a patches (patch) comes to solve this problem
Fix Snipping Tool vulnerability
The solution to prevent this vulnerability. is simple: give the file a new file name, so you don’t reveal sensitive information. And if you have already saved files in the vulnerable way, open them in Paint, for example, and save them there.
