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].firstname.lastname@example.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.
