Network Drives
Backups are always smart when it comes to data safety. I normally recommend network drives and frequent backups, however the frequent backups may increase in difficulty the larger the data store is.

My question towards cryptowall and other ransomware is can it encrypt network drives? IE can it traverse the connection from the client to the hardware behind the network drive and encrypt those files? If so, how is this accomplished?

Re: Network Drives
Hi Ryan,

Network attached storage can also fall victim to ransomware. As long as the user has read/write access to these locations, the crypto-ransomware can iterate through the files on the mounted drives, look for relevant target files, encrypt and overwrite them. From a technical perspective, this approach is no different than writing and deleting files on or from network shares. It's worth mentioning that crypto-ransomware does not use worm-like exploit techiques to jump from one host to another, it just makes use of the functionalities and permissions that are available to the user.

Re: Network Drives
I know it can traverse mapped drives, but can it hit the "favorites" from explorer as well? If not we could GPO favorites instead of mapped drives. Thoughts?

Outdated and too insecure?
Like Flash, I'm beginning to wonder if it's time to put JavaScript out to pasture for being so ridiculously unsecure.
