It it interesting to note that some threats, even unusual ones, may get wide attention and result in protective actions.  The case in point is the recent cyber threat called Heartbleed. See: 61 percent of people who knew about Heartbleed actually did something about it. Some excerpts follow:

In a survey published Wednesday, the research group found that around 60 percent of American adults — and 64 percent of those online — were aware of the problem. Even more surprising, 39 percent of Internet users surveyed were not only aware of the issue but also took the extra steps of protecting their online accounts by either changing their passwords or canceling accounts.

While that may not seem like a particularly high number, just stop and think about how difficult it is to get 39 percent of Americans to do anything. And, according to researchers, the fact that the vast majority of people who’d actually heard about the flaw went ahead and took steps to protect themselves is pretty significant.
