Don't Ignore Security Updates: QNAP Fights Ransomware by Force-Installing NAS Patch
In a bid to slow the spread of the DeadBolt ransomware, QNAP last week force-installed updates to its network-attached storage (NAS) devices. It didn't really go according to plan for some users, though, so QNAP today issued a statement about why the move was necessary.

We are constantly looking for ways to improve our products. Future system software updates may include changes that help users better manage the update process."

But many people don't apply a security patch on the same day or even the same week it is released. And that makes it much harder to stop a ransomware campaign."
