Ransomware | A simple ransomware for my school 's project | Cryptography library

I have problem deleting the following folders from the exclusions because my CPU is on 90% Usage because of these exclusions and I don't know when and why even they are on my list. I have updated windows yesterday and my CPU starts heating up... I scanned the PC and no threat detected. But suddenly I opened the exclusion list and found some garbage is in the list which is not able to delete while the Remove button is disabled. Is this a ransomware update attack or a malware attack on Microsoft server side which is providing vulnerable updates?

I am working on Ransomware for learning.

So I Copy-and-pasted this and edited it like this but When I encrypt and decrypt a text file, it appends a string that looks like a random string. How can I fix this issue?

like:

I'm storing backups in Cloud Storage. A desirable property of such a backup is to ensure the device being backed up cannot erase the backups, to protect against ransomware or similar threats. At the same time, it is desirable to allow the backup client to delete so old files can be pruned. (Because the backups are encrypted, it isn't possible to use lifecycle management to do this.)

The solution that immediately comes to mind is to enable object versioning and use lifecycle rules to retain object versions (deleted files) for a certain amount of time. However, I cannot see a way to allow the backup client to delete the current version, but not historical versions. I thought it might be possible to do this with an IAM condition, but the conditional logic doesn't seem flexible enough to parse out the object version. Is there another way I've missed?

The only other solution that comes to mind is to create a second bucket, inaccessible to the backup client, and use a Cloud Function to replicate the first bucket. The downside of that approach is the duplicate storage cost.

I'm using reactjs as frontend and expressjs as backend. the server got hacked with a low power ransomware but didn't affect the website files themselves but i had to add firewall on mongod instances to limit the other IPs to access the database and it all worked out great, after that i tried to add an item in the database using the frontend and it worked alright reading the data works and adding data works the problem was with the deleting when i delete using postman the request is sent and deletes the item ok, and when using firefox dev tools i edited my request to delete the specific item and it deleted it but when using frontend it doesn't do anything no request is sent doesn't give me any response no status codes no nothing. The Frontend:

Due to a ransomware virus, we had to restore a back-up image of the TFS server code repository that we made some days ago.

Fortunately I have an updated copy in my local workspace with the latest changes that were checked in just before the disaster. The snapshot restored does not have this latest changes. So now some files in my local workspace are newer than those in the snapshot restored, I mean my local workspace has some files which contain changes not present in the snapshot restored. Furthermore and despite of some files in my local workspace are different from those in the snapshot, they are not marked as checked-out in Team Explorer.

As the latest changes are in my local workspace (and not in the snapshot because they were lost in the restore process) I would like to check-in my local workspace into the current restored snapshot so that my local workspace gets exactly the same as the snapshot (TFS server code repository). How can I do it?

I have thought to perform a "Get Latest version" on my local workspace in order to sync it with the snapshot (code repository). I understand that "Get Latest Version" will find the differences (and conflicts to resolve) between my local workspace and snapshot and then it will automatically check-out the necessary files so that I can review and check-in them later. Is that the correct way to proceed in this situation? Am I right? Also, as far as I know, doing a "Get Latest Version" don't delete the changes locally in my workspace, right?

Recently my computer was plagued by a .help ransomware virus that appears to have come from an infected word document on the web. As it started renaming files(.[helprecover@foxmail.com].help) and encrypting my C drive files from the top down (alphabetically), I noticed what was happening when some program shortcuts started to go white. The only thing that slowed it down and actually bought me time was the virus was held up trying to encrypt the huge sum of Matlab files one by one, which it never finished todo. (Btw windows defender did not detect anything only once i put malwarebytes on my laptop i was able to quarantine it).

Essentially my question is far fetched but mathematically or conceptually is it possible to create a file or program that is not large but would take forever (long time) to encrypt with AES or the RSA encryption algorithms?

Back in 2016 all of my data on my laptop hard drive was encrypted by the CERBER ransomware. I refused to pay Ransome money to hacker.

I have all of my important data preserved in an external hard disk. After 4 years now, I am hoping that some solution is there to decrypt my data.

In these data, there are my childhood images which are once in a lifetime memories.

Please guys I'll appreciate any kinda help. If you are professional then any premium support would work too.

Can't wait to hear from you guys.

Thank you so much in advanced, Siddharth shah

I'm very new to React and working on this example.

I've modified one of the example charts from react-vis and have it working with my local data:

This is my plotBar.js file:

Below is part of my code in which I am trying to iterate over PE files. I am still getting the same error which is:

[Errno 2] No such file or directory: '//FlickLearningWizard.exe'

Tried using os.path.join(filepath) but it does not do anything since I am have already made the path. I got rid of '/' but it did not add much. Here is my code:
