OT: Watching the Cryptowall spread. It encrypts the local PC first. Was able to contain the Network Stuff with the Alerts in Trend. Still working on the SRP’s.

Applocker/whitelisting = Enterprise SKUs. Which I hardly ever see in my space, nor does the customer base afford the time and effort. Great if you have the budget to do it, sucks if you don't have the licenses and infrastructure. On 7/3/2015 11:54 AM, Jonathan Link wrote: I was posting from my phone in a hurry, DYAC. Software Restriction, not proper pixies. Susan, I haven't seen an executable run in any location that has been blocked by SRP. IF you have a very narrow whitelist, it helps a lot.

I've blocked the user profile folder and added an exception for the desktop and a couple of other places that I can't recall. Users have to move downloaded apps to ther desktop to install. I haven't had a Cryptowall infection in 2 years.

Home users look at OpenDNS (yes even now that Cisco is buying them) Filter attachments/zips. Least priv/non admin. Block the app location (yes this impacts firefox and office installs) Google foolishit for non domain or cryptolocker group policy toolkit Education to your users that that email you got isn't a legit email.
