clipboardcache: Windows security hole?
What are clipboardcache-n files aimed at?
This morning I have found on my C:\temp\ directory 4 files named clipboardcache, then clipboardcache-1, clipboardcache-2 and clipboardcache-4, w/o any extension. All had the same size (7.49Mo).
Intrigued by this name, I opened them in my favorite text editor. Indeed, the content was an old e-mail I copied-pasted from GMail to an hexadecimal editor[1]. So, to be more precise: this was the content of my clipboard at a given instant, more than two weeks ago.
If Windows uses a temporary file to handle large clipboard content, I admit it ; but why does the OS leave such a file in seeming total read access?
I wonder whether this is a security hole that Microsoft engineers forgot to fix. Perhaps the files were created by PS-Pad?
I could not reproduce the issue.
I tried to contact MicroSoft in order to submit a bug report, but the only way I found was to phone them in the US… I doubt many bug reports reach MicroSoft headquarters[2]
This is pretty simple, it’s called “temporary” for a reason. This has more to do with your lack of cleaning temporary files in disk cleanup. If you take the time to learn the windows OS and file structure system, or how applications work, then you won’t be complaining about the things you don’t understand. Otherwise, don’t question why it’s there as you are obviously not capable of understanding things past Lamens terms.
Also – The company is called “Microsoft” it’s not “MicroSoft”.
