While looking for something else, I discovered that Google (of course) knows what people are trying to hack lately:

 
Agreed, this information is not overly useful.  These hacks are basically on the opposite end of the threat scale from the over-hyped "Advanced Persistent Threat" (APT).  Let's call it the "Basic Sporadic Annoyance" (BSA), just to come up with a new acronym :).

The BSAs still tell us though what "average" wannabe hackers seem to be interested in breaking into, namely: websites, online games, wifi and phones.  Cars, pacemakers, fridges and power plants are not on the list, suggesting that these targets are apparently not yet "popular" enough.

Being fully aware of the "filter bubble" https://en.wikipedia.org/wiki/Filter_bubble we had several people try the same search, and they largely got the same result. Looks like Facebook really IS currently the main wannabe hacker target.  But Facebook don't need to worry all that much. Because if you just type "How to h", then the suggestions reveal that other problems are even more prominent than "hacking Facebook":

If your results (of the "how to hack" query, not the latter one) differ significantly, please share in the comments below.  Updated to add: Thanks, we have enough samples now :)
