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?

Outdated and too insecure?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.

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?

CVE-2020-27605
PUBLISHED: 2020-10-21
BigBlueButton through 2.2.8 uses Ghostscript for processing of uploaded EPS documents, and consequently may be subject to attacks related to a "schwache Sandbox."
CVE-2020-27606
PUBLISHED: 2020-10-21
BigBlueButton before 2.2.8 (or earlier) does not set the secure flag for the session cookie in an https session, which makes it easier for remote attackers to capture this cookie by intercepting its transmission within an http session.
CVE-2020-27607
PUBLISHED: 2020-10-21
In BigBlueButton before 2.2.8 (or earlier), the client-side Mute button only signifies that the server should stop accepting audio data from the client. It does not directly configure the client to stop sending audio data to the server, and thus a modified server could store the audio data and/or tr...
CVE-2020-27608
PUBLISHED: 2020-10-21
In BigBlueButton before 2.2.8 (or earlier), uploaded presentations are sent to clients without a Content-Type header, which allows XSS, as demonstrated by a .png file extension for an HTML document.
CVE-2020-27609
PUBLISHED: 2020-10-21
BigBlueButton through 2.2.8 records a video meeting despite the deactivation of video recording in the user interface. This may result in data storage beyond what is authorized for a specific meeting topic or participant.
