I'm not aware of the last, but in previous versions, ransomware encrypt all files and after this he delete original files. If you have a trash/recycle configured, you can recover these files.

Hi All, Is there anything in Samba that will help protect against ransomware? -T -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Computers are like air conditioners. They malfunction when you open windows ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I had to deal with ransomware at the end of April. One of the PCs on my customer's network was infected by opening a realistic looking email apparently from a genuine supplier to the company and personally addressed. The infection occurred on Wednesday, but encryption of the server only took place late on Friday afternoon,...

I'm jumping in here late. There's been a lot of good suggestions already. Something I haven't seen mentioned is rsnapshot. The solution to ransomware like this is a good solid backup regimen and rsnapshot can be part of that. rsnapshot is opensource and based on rsync .. it requires a unix filesystem that supports hardlinks. It works on making a complete snapshot of the file system every 'n' periods. you specify who frequently. The cool...

Samba/Windows shares can be discovered, that's how Windows itself does it when browsing the network. It wouldn't be difficult for a virus to use the FTP protocol as well. However it wouldn't know what server to connect to and what username/password to use if prot...

That's why I'm asking here for (better) ideas. And I posted one idea I found (the ransomware-samba-tools link earlier) already, but I'm just trying to get some dialogue / brainstorming going on here... :-) MJ

Hi all, Just out of curiosity: is there anything we can do, on the samba side, to counter the recent ransomware attacks? (or limit the damage done) I'm thinking like: limit the number of files per second a client (workstation) is allowed to edit, or some other smart tricks..? It would be nice if samba could be an extra layer of defense. Something perhaps a vfs module could help with..? Anyone with...
