Re: New ransomware that targets backups. Are we susceptible

Post by dburris »

What someone gains admin access to the Veeam B&R server, deletes the backups, and then encrypts files. I understand we could use external USB drives or tapes to keep the data safe. But what if we are relying on Veeam Cloud Connect for off-site backups. I see there is an option there too to "Delete from disk". Is there a way to keep the Veeam Cloud archives safe from in this scenario?

Thanks,
Dave

Your service provider certainly can arrange that. One way that immediately comes to my mind is to setup periodic storage-based snapshots on backup repository.

Is it enough to use windows defender as antimalware scanner on each computer? In addition, I can conduct strong password policy, update all antimalware and net protecting software, plus keep primary security rules https://www.bestvpnrating.com/blog/9-ti ... rd-snowden I mean if I maintains security system in decent order, will this new malware penetrate in the system or pass round?

Of course it would, because Windows Defender only carries signatures to known malware. If you're "lucky" to get a newly released one, it won't protect you.

hey guys
I see some of you are using non domain joined veeam servers. How do you go doing restores directly back to the servers. IE AD users, Mailbox objects. We found in version 8 it failed to complete file restores correctly unless it was on the domain.
We always use tape however would like some tips on securing the backup repository

Hi Luke,

Can't remember well how it was in v8, but today this should not be a problem. For example, see here https://helpcenter.veeam.com/docs/backu ... tml?ver=95 to recover AD objects where you can specify a particular username / pwd to connect to your AD for restore. Do note however that your networking must allow this so look at the requirements for ports also.

On the backup repository. I tend to use a specific account to connect to the backup repository. An account that isn't used for something else. Ransomware tends to run in a user context (the user that it used to start its bad things) so if that account is not used, it won't succeed in encrypting your backup files. Please don't forget to store that account / pwd somewhere in a safe (preferred outside the company premises) so that in worse case you have access to the files :-)

Any know cases of this latest Ransom-WannaCry infecting backups, from the AV vender info, the VBK extension isn't listed, so hopefully its ok.

Hi Mark,

From what I can find, VBK are indeed not affected by this one. But never say never as these tend to change very fast :-(. Don't forget that MSFT has patched the security hole with the March update so make sure your machines are patched!

We moved Veeam to a backup-only domain (no-email, no web-browsing, etc.) to gain the benefits of AD, while limiting exposure to Ransomeware.

does anyone have a nice powershells script we can run to target client and servers to see if the computer is protected from this attack?
for me it seems like the ms17-010 website refers to very many different KBs and also that some KBs replace other etc.
Would be great to have a powershelgl script we could execute on all servers and clients to verify it this gap is closed.
