Hi, This version is no longer vulnerable to a simple factorization attack. I'm still analyzing it in case there is a new vulnerability.

JonnyTech commented 8 years ago

@Googulator, can anyone here do anything to help?

mariosangiorgio commented 8 years ago

I'd be happy to help too

juanpark commented 8 years ago

Yep hearing reports on .xxx .ttt. .micro on the Korean front also.

annadn commented 8 years ago

What about .zzz version? Does it work for it?

Demonslay335 commented 8 years ago

@annadn .zzz is one of the "older" variants, this script will still work for it. It will currently only not work for .xxx, .ttt, and .micro.

annadn commented 8 years ago

@Demonslay335 Thank you so much for the answer. Hope all of us will get our precious files back!

I had been atacked with .vvv variant a couple weeks ago... today my neighbour was too, with .micro

(argentina)

i've already took precautions making a backup on a hard disk... my neighbour wasn't so lucky..

is it possible to know what program are they explointin? adobe?

Demonslay335 commented 8 years ago

@fedeq4 Typically it is a spam email with a bad attachment or link to a malicious site that runs a exploit kit. Exploit kits attack multiple things at once; its like a shotgun attack against the browser, Flash, Shockwave, and any possible plugins it can detect. The email is directly an executable that is run to start the infection.

@willyset Do you need help with decrypting your .ccc files? If you have trouble with the instructions in the readme, you may post a link to a sample encrypted file and I can help you.

willyset commented 8 years ago

I've managed to partially decrypt my files, but I lost files due to this virus is able to return?

I am confused how to restore my files were gone after I hit it and my virus scan with SpyHunter and Malwarebytes, and most of my lost files including photos of my family, anyone have a solution for this?

if file encryption stay a little longer finish.

@willyset The virus and those tools do not delete any personal data. The virus encrypts all files, but you should be able to decrypt them if you were able to get the proper key. Did TeslaCrack skip files? You may have only decrypted one of the PrivateKeyFiles, which there can be many if the computer was rebooted during the infection. If you send me a sample file, I can get you the "master" key that should decrypt all of your files.

ohh then why with my files, why be lost, confused,, I've sent examples of his files in a previous email, I try decryption but the results are nothing like this:

I don't see any links to sample files. If you are replying by email to GitHub, it doesn't accept attachments I don't think. You may email me a sample to demonslay335@gmail.
