I did some checking into the threads you posted. In some of the threads users were simply posting questions and concerns. As for the actual vulnerabilities brought up in the threads, we have either already fixed them or will shortly. The vulnerabilities we have fixed can be found listed in the firmware release notes.
I want to reiterate, however, that we do take security issues seriously, and we do work towards making our products as secure as possible. So, if an issue arises, you can rest assured that we will jump on it right away. Moreover, we have been notifying users when we’ve identified legitimate security issues. I know because I’m the one that posts them in the forums.
Furthermore, and I’m not sure how aware users are of this, but WD has already become very proactive in soliciting help from users when product issues arise. We contact the users, usually within a day or so, to get as much information as we can to correctly identify and replicate the issue on our test products.
Finally, what you or others may perceive as silence, is simply us working with the affected users behind the scenes investigating the issue. If it turns out to be a real bug, there is nothing more that can be done until it is fixed in another firmware update, hence the apparent silence. What we have started doing more of is posting what has been fixed in a firmware update.
Hopefully, this helps to clear things up a bit.
