Some years ago, hackers used to be highly sophisticated experts.
Meanwhile, the majority of attacks are driven by silly script kiddies
using high sophisticated tools without understanding what's going on.
Reading some of the spams I receive I found that many of them seem
to be sent with the very same software and address list. There are
billions of spam, but only a few spamming tools. All it takes is just
a simple software upgrade to the next version of the tools to defeat
that hash method. Once spammers learn how to do it, all spammers will
know how to do it. There is not significant number of "low-hanging
fruit".
