hello all,

 

one of our network drive has been encrypted by a crypto virus. all DOC XLS PDF files have now the JSE extension and an unique size 562ko

we have no ransom note. it came from an user who opened an attached file containing a JSE script disguised in PDF in a RAR file. it created a fly.jse file in the startup menu and many cmd.exe in background that renamed the files on network drive.

ID ransomware says: SHA1: 3bc738d2d662bcb5f3325b3e1f0f011a68e4ba45

trend micro says nemucod but cannot decrypt it.

do you have an idea?

i'm gonna try to link a crypted file

Samples of any encrypted files or suspicious executable's (installer, malicious files, attachments) that you suspect were involved in causing the infection can be submitted (uploaded) here with a link to this topic. There is a "Link to topic where this file was requested" box under the Browse button...it's best to compress large files before sharing. Doing that will be helpful with analyzing and investigating by our crypto malware experts.

After our experts have examined submitted files, they typically will only reply in a support topic if they can assist or need further information. If not, then the submitted files were not helpful.

It is identified as Nemucod because that is also the name of a dropper, not just a ransomware.

 

Did the RAR file come with a password in the email or something? It is not opening for me, as it is an unregistered ACE archive that may be password-protected. I'm working on trying to get the payload for the actual malware itself.
