Hi everyone,

I am new to this forum, please excuse me if I post in the wrong thread.

Yesterday our office network was hacked by some kind of crypto virus and almost all files from shared folders on two machines were encrypted.

The encrypted files were renamed to [original file name].id-8809371137_helpme@freespeechmail.org.  I didn't find any files with instructions for paying ransom or similar. No nag screen with demands.

The affected machines are on Windows 7 and Windows 10 and are protected by Kaspersky Internet Security. Kaspersky didn't report for intrusion. I ran a full scan on both machines and don't found dangerous or suspicious files. 

I can upload an encrypted file for analysis, but I don't know where.

Any help will be appreciated.

Thank you Jo*,

it seems that this is my case. I don't have desktop wallpaper changed, maybe because I disconnected from network before the end of process . I started the RkhniDecryptor and now I'm waiting with my thumbs crossed. 

Regards,

Kiril

It is believed that this infection is part of a ransomware kit that different affiliates utilize with their own payment email addresses which explains all the "@" ransomwares which have been reported.

There is an going discussion in this related topic.Rather than have everyone start individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in that support topic discussion. To avoid unnecessary confusion...this topic is closed.

Thanks
