*Sigh* Do a search on SpiceWorks, though. Was about to start making those changes when I found out, SURPRISE!!! Not so! The files get encrypted anyway. Now, I'm one of the few slackers whose users have Admin rights (I know, I know.) and I was made fun of by a colleague in a different company about how that and GPOs and such would have saved me.

Particularly pwned machines (or ones that are hit with another infection by one of the previous methods) will be set up to be remotely commanded to download and install the Crypto program. Files have also been delivered directly via DropBox and other file sharing accounts.

Or the Email will have an infected attachment that is NOT caught by most (almost ALL) AV programs for the first day or so. Usually it comes in the form of an Email with a direct link to click on (Scariest one I've seen? Link just said 'Click here to open this message.') that will take you to an infected site. Getting CryptoLocker and it's variants is horrifically easy. There's other telltale signs as well, but that one is the most obvious.

Tell me more about the PC that got your network infected and how you dealt with that employee. Furthermore, we didn't even have to touch our Veeam backup system. We were up and running by noon Monday, but had we considered the flash pool issue, we could have been back online by 9 a.m. Nimble Storage really came through for us, and so did the support team from Pernix Data. We now know that we need to consider removing VMs from the flash pool before restoring from a snapshot, and we need to retain more hourly snapshots. Overall, I'm pleased with the fact that we were able to quickly save 99.9% of our documents from ransomware. We only retained 15 hourly snapshots, so we have changed that to 24 for future incidents. By the time we looked on Tuesday to pull from Monday, the morning snapshots had been over-written. We did have snapshots running, but not enough were retained. Unfortunately, we lost Monday morning data.

I took another host server and cloned the VMs from Friday afternoon, and I was able to see clean documents offline (documents created after the ransomware infection) and I'm currently working on moving these files back to the production servers (after scanning them, of course). However, we still had snapshots of Friday afternoon. Those servers booted right up and the data was clean and unencrypted. The first clone we booted was still infected, so instead of using a clone from Friday morning, we used the snapshot from Thursday night. Once that was done, we were able to boot the cloned VMs. We had to call Pernix Data support and their engineers had to manually clear the VMs from the flash pool. Because of this, we couldn't boot the cloned VMs. We should have removed the VMs from the virtual flash pool before attempting to run from a cloned snapshot. We found that the outbreak occurred midday the previous Friday so we wanted to run from a snapshot on Friday morning. I called Nimble support back for a walk through in our first snapshot recovery. Sure enough, I found decryption instructions on our shared folders.ĭue to the infection's symptoms, we were quickly able to find the machine that caused the outbreak and quarantine the PC and the two servers affected. After a brief chat, the technician suggested I look for evidence of ransomware. On my way to the office I called the Nimble Storage support line to discuss the snapshot consolidation errors. The interesting thing is the VMs worked just fine, but all documents were corrupt. He rebooted the virtual servers, but the problems remained. He mentioned seeing VMware errors regarding snapshot consolidation. Monday morning: I got a text from my coworker - our file servers are down. To sum that up, we have Pernix using flash writes on the host and Nimble with flash reads on the SAN, giving us killer performance. (If you've never heard of Pernix, check them out.) We use Nimble Storage for our SAN and Veeam for our backups.

If you'd be interested in writing a post on the subject of best practices, security, networking, backup, storage, virtualization, or MSPs for the series, PM Eric to get started.Įquipment check: We are a VMware house running HP Proliant D元60 G8 hosts, each with one 480GB Intel 730 series SSD for a virtual flash pool powered by Pernix Data. This is the 363rd entry in the Spotlight on IT series.
