G+_William Burlingame Posted February 25, 2017 Share Posted February 25, 2017 I've heard that unmapped NAS drives are safe from ransom ware. Is there any validity to that statement? Link to comment Share on other sites More sharing options...
G+_Scott Snodgrass Posted February 25, 2017 Share Posted February 25, 2017 I'm sure it could still spread to it somehow. Link to comment Share on other sites More sharing options...
G+_Ben Tyger Posted February 25, 2017 Share Posted February 25, 2017 William Burlingame (short answer) ? Does unmapping make network shares immune? No. Does it make it harder to infect? Yes. (Long Answer) basically it depends on how intelligent the malicious code is. Getting a list of enumerated drives ( from the OS) is easy and the chances you'll have access to them is pretty good. But malicious code could also try to browse the local network. Any shares it finds, it could try connect to those. But it also may raise suspicion if lots of connects are bad with invalid rights or connects that user wouldn't normally use. So malicious code may not try to do it.

G+_Lance Foxcoonbit2019 Posted February 25, 2017 Share Posted February 25, 2017 No your computer sill knows it's their so the ransom ware will see it. just discent the drive and it will not see it. Link to comment Share on other sites More sharing options...
G+_Jason Marsh Posted February 27, 2017 Share Posted February 27, 2017 I'd say anything on the same LAN as an affected machine is vulnerable. Daily offsite backup is good insurance against data hijacking. How to prevent users clicking on stuff, talking to "Microsoft" when they call, or opening unexpected attachments; there's no fix for that. Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted February 28, 2017 Share Posted February 28, 2017 Basically, what everyone else said... There's no way to be absolutely certain that your NAS can't be touched by ransomware. If you think there's a good chance you'll get bit, mapped drives are just offering your data up on a silver platter. That's not to say don't do it - just be aware of the risk. Really, a good off-site backup like CrashPlan or Carbonite is the only way to feel safe in my opinion. That may not be a possibility/option for everyone. It took me several months to get the first backup finished on a decent cable connection (5 Mbps upload at the time I think), but I consider that worth the wait. Also, keep passwords on things even for your internal network. You might think your NAS is safe from ransomware because it's not accessible from the Internet and not mapped to any computers, but it's trivial for a virus to scan the network for open file shares.
