Which steps should I do to recover my files which are affected by ransomware.

Please share you experience on this.
Thanks for your time
First you should know what type of ransomware you are infected with. In your case https://www.pcrisk.com/removal-guides/15698-pdf-ransomware this might help you.
Also, You should give a try to some free reamsomware decryptor tools such as STOP Decryptor,Rakhni Decryptor provided by some antivirus companies for free.

If you get the variant of the ransomware you are infected with you can try a specific tool on your files if that helps you.

Apologies if this has been asked before. I tried to find an answer elsewhere, but couldn't find a response that resolved my issue.
I inherited some code for downloading and processing satellite data without a lot of explanation and I am required to make it work. The intention was that this code should run without me needing to do anything but run the script, but there is a bug that prevents it from working properly.
I've been able to narrow the issue to (probably) one line of code:
ds = rioxarray.open_rasterio(tempFile).compute()
where tempFile represents a string for an s3 bucket. The exception message I receive about it is as follows: '/MOD13Q1_A2022193_h09v04_061_2022215010516.hdf' not recognized as a supported file format
I have almost no experience with xarray and rasterio, so I don't have a good idea of where to begin to resolve this. The file does exist at the location and rasterio can process .hdf files (I think), but if that's the case, what may be going on here? Any help is appreciated.
Thanks!
I think I did some stupid thing by creating random data using some command dd if=/dev/urandom of=20GB.bin bs=1GB count=16 iflag=fullblock
in huge size. Actually I was testing the behaviors of something when disk is full.
However Now I wish to delete this. I deleted the dev/urandom folder hoping it will do something, but it seems nothing was deleted without making any difference.
I see some commands online like wipe and shred, However now my dev/urandom folder is deleted, so what exactly should I do now ?
Any kind of help will be great.
you saved the random numbers to 20GB.bin thus you can do rm 20GB.bin to remove it. /dev/urandom is a special file bound to a tool and does not save random files, but just creates them on the fly. Some other tools might depend on /dev/urandom so deleting this device file might let them crash.
I wonder what's the difference between the LocalCacheFolder and the TemporaryFolder.
Regarding MSDN, the LocalCacheFolder is not backed up/restored, but the temp folder isn't either, is it? What's the difference, then? Will only the temporary folder be deleted when I clean up storage manually`?
MSDN doesn't tell me a lot, so I hope someone can tell me the difference. Thanks in advance :)
Both are folders that aren't backup up. The difference between them is that the OS may delete files from TemporaryFolder whenever it needs additional space. With LocalCacheFolder, you're responsible for deleting the files you don't need anymore.

I've been trying to figure out if it is possible to have a jackrabbit repository to be run completely in memory.
Whatever I try in order to run the repository fully in memory, I still end up with a repository directory full of files on my disk?
If anyone has figured this out I'd much appreciate if you could explain how to achieve it.
Thanks

See this 4+ year old blog post, which hopefully still applies and is helpful: http://modeshape.wordpress.com/2008/02/22/speedy-unit-testing-with-jackrabbit/
reputedly, it is possible to make a "malicious" Word document. Maybe using embedded VB script? Anyway, not sure. My question is, is it possible to make an app that safely scrubs all such insertions from a .doc file? Of course, preferably this app should work without actually opening that file in Word application since presumably that may be sufficient for the machine to get damaged.
Is there something like that out there already? Is this even a problem worthy of discussion or in reality there is nothing really malicious that can be done using the Word documents distributed online?
ADDED LATER: johnnyArt, yes, and when you get dirt on your clothes, make sure to go to mommy and tell her about it. Mommy knows best! As a computer programmer, I am interested in learning more about how the world works, including how the world of .doc files and their embedded malicious scripts works. As for using the antivirus and anti-spyware, I will handle these issues without your precious advice. As will, probably, most other users of this forum.
You should scan the file with your antivirus/spyware of choice.
My advice is, if it has malware in it, it's not worth "cleaning" it for use.
Get yourself a clean copy somewhere else.
