It seems that: "with open(filename, 'rw+b') as f:" in modify.py doesn't works in Windows.
I tried a number of solutions without success. How can we get around this?

I guess there is some issue with open file and seek() method on windows..

Thx Daniele

Good evening,

Please could someone run through how exactly to execute (encrypt/decrypt functions) the script?

Kind regards,

Alex.

This is a reference to the comments made on #7. The windows implementation on python seems to struggle with reading and writing to a file without seeks and flushes separating them. While I was seeking between the read() and write(), I did not between the write() and the next blocks read(). One hacky way to solve this is a seek. Any seek, even if it does nothing, like f.seek(f.tell()) will fix it. Or the more proper way (which will come in a commit fixing this issue soon) is f.flush(). I just wanted to document it.

.

Is it possible to add some explanation in the README about the structure of the code and the algorithm?

It would not only make this project more educational but it would also make it easier for people to understand the code better and thus to make contributions.

Thanks.

I am trying to run this, I'm making a demo for small comapnies about the risks and dangers of Ransomware, So we want to demonstrate in a Virtualbox Win7 machine what could happen.

Now when I run the software at first it gave a permission error (set start folder as: "C:\Users"). So I tried the active user by doing the following:

# change this to fit your needs.
    startdirs = [os.getenv('USERPROFILE')]

I've confirmed that this works with a print function inserted.
Buuut.. I run the script now by opening an Administrative CMD and running

python C:\python27\Ransom\main.py

But it just takes soooo damned long without any noticable actions happening..
Just let it run for an hour, nothing happened.
It's a clean Win7 image with Python2.7 and PyCrypto installed I didn't have much files on here so I used "C:\Users\user\Pictures" as start dir and put some sample pics in there..

Eventually I would like to use pyinstaller to compile it to an executable (for believability and relating to the bussinessmanagers)

So is there anything I'm missing?
Also is there a way to just run this against C:\ without permission errors?

Thanks in advance!
